The '''Gellar Field''' is a energy field that protects a space ship, oneself, and crew from getting a Class 10 Clusterfucking from [[Chaos]] while traveling in the [[Warp]].

As everyone knows, the ''only'' way to get ''anywhere'' without taking fucking forever is to use the Warp. That is, unless you are the [[Eldar]], in which case you can go much faster with [[Webway]]s as long as you don't get lost (actually Webways are usually slower, trading speed for safety). Or you are the [[Tyranid]]s and can use [http://en.wikipedia.org/wiki/Alcubierre_drive gravitational Star Trek bullshit]. Or you are the [[Necron]]s and can screw the laws of physics seven ways till Sunday. Or you are the Tau who invent new and less-shitty-then-previous but still-shitty-non-Warp-limit-as-x-goes-to-the-speed-of-light drives like every 20-30 years (well, we say “invent” but the Eldar noted their “crippling lack of creativity” so more like they go Blood Raven on intellectual property...so, like Space China but small). So maybe not everyone knows. But everyone ''definitely'' knows that all sorts of fucked up shit lives in the Warp, whose '''ONLY''' goal is to fuck you up (both literally and metaphorically) in 57 (or more) different variations. The Gellar Field prevents this from happening, so the Servants of the [[Imperium]] can go to your planet and kill your [[Cultist|Chaos-worshiping]] ass!

== The Warp, Giant Space Cathedrals and You ==
Its been mentioned a few times in the fluff that while the Gellar field on Imperial ships most definitely has a mechanical component, the field is reinforced by all the giant statues and gold bling that the humans of the setting feel the need to shove on every square inch of the hull. It actually makes a kind of sense when you think about it: The warp is a realm governed not by boring old logic but rather the thoughts and feelings of everyone in real space. Since Imperial ships are already borderline worshiped by humans as the physical manifestation of humanity's might and manifest destiny to rule the stars, turning them into ''actual'' space borne cathedrals (I.E. places of worship) could have an effect similar to the old belief that demons can't enter holy ground.

== Let's Take an Example ==
The [[Orks]] are a fantastic test case of what happens when someone who doesn't use Gellar Fields travels through the Warp.

The Orks ''can'' use a ''similar'' device to a Gellar Field, that focuses the power of the WAAAGH! into an energy field to keep the Daemons and other warp monsters away. It involves jamming [[Awesome|Really Big Teef]] onto the ship in an effort to frighten passing Warp-monsters. Hell yeah! This may or may not be a kind of ferryman payment to Gork or Mork for safe passage. Of course, if that technique doesn't work, the Orks will usually just give the unlucky daemons that tried to board their spacecraft a good stompin'. Either way, the Orks like both outcomes.

Many grassroots WAAAGH!s get underway by hitching a ride on a passing [[Space Hulk]]. These are convenient because they can enter and exit the Warp (saving on having to make a very complicated Warp Drive), have tons of cargo space (for all of the boyz to ride in), and frequently come equipped with friendly passengers such as Genestealers, Daemons, Chaos Cultists, or other some forgotten horror (for in-flight entertainment). This travel method, while common for Orks, would be ''utterly disastrous'' for any other race. Space Hulks have no guidance systems: they can spend decades in the Warp and come out right where (and when) they started, or spend a few days in the Warp and arrive hundreds of years in the past around a totally uninhabited planet. While all of this waiting around is happening, the totally unshielded Hulk is ripe for invasion from Daemons, who not only look at Realspace beings as a food source but are actively drawn to anything Real that happens to pass by. Brainsuckers, sanity-feeders, life-drainers, and eight-million copies of [http://www.scp-wiki.net/scp-106 Radical Larry] are on standby to slither into the Hulk and track down any Ork stupid enough to have hitched a ride in the first place. All of that would be bad enough, but because the Warp and Realspace don't mix well, Space Hulks are constantly in danger of of doing things like [[wat|phasing into themselves, having infinitely-looping corridors]] and generally getting all M.C. Escher.

It's lucky for the Orks that they don't care much. Any other race would be driven mad, slaughtered entirely, and/or be devastated to learn that they arrived decades too late (or hundreds of years too early) to stop the conflict they were sent to fight. Orks by contrast will readily fight anything and everything, including themselves (and terrifying horror-movie antagonists) as a general first response to unpleasant or unfamiliar circumstances. Due to their below-average intelligence they generally take eldritch horror with a puzzled chin-scratch and eventual dismissal (or assault and battery). Ork WAAAGH!s are also fairly independent of things like nations or strategic timelines, so "showing up too late" is almost always a non-issue. (In one instance the Orks in question showed up too ''early'', catching their own WAAAGH! right before it left. Long story short, the Warboss killed his past self to get two of his favorite gun and the WAAAGH! stopped in its tracks) The above is not to say that Orks who hitch a ride on Space Hulks are perfectly fine. They aren't. Many would-be WAAAGH!s begin and end when the horde jumps aboard a Space Hulk, and it shows up on the other side of the galaxy with a few thousand new sets of Ork skeletons inside.

Now i realize that this is gonna need some dumbing down, think of the Gellar Field as ways to enter a party. The Imperial way is to sneak in without drawing attention and getting swamped by the crowd. The Ork way of doing things is to jump into the sea as long and as annoying as possible, either annoying everything away or, much like a college Frat party, drawing in things either like-minded or things FAR worse. but then again these are Orks we're talking about, they probably think whatever jumps on to their boat is just some fighting practice until they reach wherever they seem to be going.

As of the opening of the Great Rift, [[Nurgle]] has devised an insidious new plague that has allowed him to bypass the shielding of the Gellar Fields. The <s>"Gellarpox"</s> {{Blam}} {{Blam|Engineer's Syndrome}} works by infecting the laborers who maintain the Gellar Field generators, and more importantly it spreads through ''the generator itself'' (luckily, said generator has to be malfunctioning, but even a single minor malfunction can cause it to be infected). The infected humans show no initial symptoms other than strange dreams, but are subtly compelled to sabotage their work so the Gellar Field begins to weaken. When the time is right, they mutate and the infected generator turns into a horrific mass of biomechanical infectious tissue that endlessly spawns mutants, abominations, and the occasional daemon, almost certainly dooming the voidship the generator was formerly a part of. Although, it seems to keep doing its job so if you can hold the line until entering realspace and then blast the thing, you have a chance.

Tau (τ) is the 19th letter of the Greek alphabet, 300 in Greek numerals, and also the name for 2π.

It is also the name of the Warhammer 40K race known as the '''Tau''' (or "bluies", as the Valhallan 597th call them)(or "Space Communists" as anyone on /tg/ will tell you), (or "T'au" as GW copyright lawyers call them) are a playable race and a minor and overall insignificant power in ''[[Warhammer 40,000]]''. When first discovered by humanity, the Tau were a barbaric and primitive people. Their planet was then trapped in a warp storm for a few thousand years and they emerged from the other side as a unified species, led by the [[Druids|mysterious]] Ethereal caste and devoted to the concept of the "[[Greater Good]]". Their new empire supposedly has around 115 worlds, although only 36 of those have any sort of activity on them and the rest are either useless rocks or not shown/mentioned at all. They were growing until recently, when the Imperium sent a large invading force to counter them.

Although a dystopian society in its own right, the Tau Empire is noted for being one of the LEAST awful places in all the galaxy of 40k. It's also [[Derp|not really an empire]]; the Tau government, the Ethereal caste, is essentially an edifice of meritocracy and nepotism-Tau leaders are appointed to their position by even higher ranking leaders and/or a council of their future peers; the highest ranking Tau, the Aun'O, is elected by his future underlings, much like the Catholic pope, but is still simply considered the weightiest voice of a group (like a prime minister), not an Emperor with absolute power. While Tau civilization has the behavioral tendencies of many empires throughout history (expansionism, military conquest of weaker states, forcible integration of the conquered peoples, etc.), it is the government structure of a state that makes it an empire, not foreign policies. Essentially, they are ''imperialist,'' but not an ''empire''. That said, an imperialistic nation is an empire, not the form of government. So, it is an empire without an imperial government. Like the United States during its Westward expansion.

The Tau started as a classic case of successful design-based [[Troll|trolling]] on the part of [[Games Workshop]]. They were originally developed because GW felt that their setting needed an optimistic race and that their wallets needed more money, which they could get by selling shedloads of 40k to the robot-obsessed Japanese. The Tau, therefore, are the least [[grimdark]] faction in the game; [[Tau Diplomacy|they're the dudes willing to negotiate when they've beaten their enemies]] ([[The Beast|we cannot forget the green skinned diplomats our boy sent out during his siege of terra]]) while all the others are either too [[Chaos Space Marines| murderously psychotic in ways incomprehensible to anyone who does not share the same batshit insanity]], [[Imperium|religiously overzealous]], [[Eldar|arrogantly indifferent]], [[Orks|simplemindedly violent]], [[Necron|murderously enigmatic]], [[Tyranid|more interested in eating you than anything]], or [[Dark Eldar|all of the above]] to offer such courtesies.

This began to change in the 6th edition. For all the claims that GW doesn't listen to its fans, someone seemed to have heard the incessant bitching many fa/tg/uys made over the Tau [[Belisarius Cawl|being shoehorned into the setting]] [[Primaris Marines|in the worst way possible.]] As a result, the Tau began to take on an Orwellian flavor and Imperium-esque elements, with the Ethereals being totalitarian autocrats performing acts of ruthless indifference towards their subjects, including [[Nazi|eugenics]] or up to [[Exterminatus]] of lost races (e.g. Orks and Tyranids), in the guise of being for the Greater Good.

Twelve year old [[fluff]] (from ''[[Dawn of War]]'', supported by [[Deathwatch]] supplements describing Achillus Crusade) has them <s>arbitrarily sterilizing the rebelling humans on Kronus once they come under the rule of the Tau Empire</s> sterilizing a group of humans attempting to revolt and distract Tau forces in the middle of a planet-wide, 6-way free-for-all (to be fair though, had it been anyone else they were revolting against, including the Imperials, those humans would be dead, [[Grimdark|most likely the slow and painful way, or even suffer such a terrible fate as to wish for death]]).

The Tau Codex leaves ambiguous the question of just how much of their success is due to various forms of indoctrination, caste-based conditioning, and subtle mind control. This has only been exacerbated by the recent Farsight Enclaves supplement, which makes the Ethereals come off as mustache-twirling, Saturday-morning-cartoon villains. It speaks volumes about the 40k setting that in spite of all this they're ''still'' the friendliest race in the galaxy.

Also, the Tau have twenty planets after a handful were eaten by Tyranids (discounting allied held worlds and worlds with little to no inhabitants on them). Despite this, fanfiction writers who somehow got hired by GW and Tau fans alike have this strange habit of treating them like a major faction. For instance, a galaxy ruling combined empire with the Imperum and Eldar usually includes the Tau because the writer doesn't realize the Tau are one of the smallest, most insignificant minor species in the galaxy. This isn't to insult them, they can always get stronger; it's just the plain truth, currently that is. The setting stretches millennia, so who knows how far they can go, hopefully they'll become more and grow experienced as time goes on assuming the setting doesn't fall into constant grind never proceeding to the next year for decades ''again''.

One of the more hateful aspects of the Tau is that Games Workshop feels the need to make them seem viable as an army by having their power fluctuate wildly, for example, the Tau can easily subjugate Imperial Hive Worlds and deport its population so easily that it doesn't even get a footnote. You know, those planets in which the population of a single city shocked an Tau ambassador because ''the city's population was greater than the entirety of the Tau species''? Imagine entire planets of those cities, cities in which everyone is an experienced killer (which is why Space Marines love recruiting from Hive Worlds), armed and ready to fling themselves at any invading xenos to purge them with extreme prejudice. These are the same worlds whose PDF is large enough to enforce Imperial rule, and so contribute massive numbers of Imperial Guard (on top of having their own substantial forces).

As an example of this, take the Battle of Mu'gulath Bay, known as the Battle of Agrellan to the Imperium. This was a fight over a Hive World which the Tau won, how? Using Riptide Battlesuits. According to GW, the Riptide's armor was impervious to nearly all anti-armor weaponry (lascannons, krak missiles, and heavy meltas are a threat to Baneblades and knights and heavier stuff can even threaten Titans, so we know this is bullshit). The kicker though, is that '''''Deathstrike Missiles''''' ''did nothing'' when its shields were active. You know, the missiles '''''Titans are afraid of''''' and can vaporize armies? And can use Titan-killer warheads? '''Those Missiles'''. This is but one example, another goes back to the Taros campaign in which a Tau stronghold was mysteriously unable to be blown to hell by sustained bombardment from Colossus mortars and then the Tau ''sallied out'' to engage the Imperial forces and won. In addition, a lot of fights are won by their opponents being uncharacteristically stupid, for example in both the Taros Campaign and the Battle of Agrellan the Imperium suddenly forgets how to defend itself, its supply lines and in the second Damocles Gulf Crusade, engages the Tau using formations and tactics that cater to the Tau in the extreme (this is especially egregious in the finale), [[wat|and even has an assassin forget to use her gun to instantly kill her target]]. Even the Marines aren't immune to this sudden stupefying aura, as we have Space Marine Terminators wielding storm shields were shot and killed because they were too busy telling each other to raise their shields up to block the Tau's shots [[derp|instead of raising their shields up to block the fucking shots.]]

There were like three or four of these suits, by the way.

=="Naive Weeaboo Space Communists"==
[[Image:Tau Weeaboo.png|thumb|right|Cue hotblooded music by [https://www.youtube.com/watch?v=-r6xYnFDoV0 JAM Project].]]
The Tau's naiveté might seem at odds with the GRIMDARK-ness of the setting (and to a degree, a lot of it is), but the thing is, Games Workshop specifically plays this straight FOR the [[grimdark]] and ''knows'' that the seeming futility of the Tau's optimism only further accentuates the general hellishness of the rest of the galaxy - and dear [[Emperor|god]] do they play this up for maximum effect. In the 41st millennium, the Tau come across as ''more'' than a little naive to the other races; the Imperium sees any contact with aliens as heretical and will shoot them with [[bolter]] rounds as soon as they look at them; the [[Ork]]s just want to kick the shit out of things; and the [[Eldar]] see the Tau as young and powerful because of their technology but also as a race in its infancy, just staggering out of its borders for the first time and wandering into a pond full of [[Saharduin|sh]][[Dark Eldar|ar]][[Chaos|ks]].

In older fluff, the Tau were implied to have been secretly uplifted by the Eldar through the creation and subtle control of the Etherals (especially the mind-influencing pheromone secreting gland at the base of Etherals’ spines) and guiding them through reverse-engineering Imperial technology from the ruined colony ships. Eventually the Eldar abandoned them because the Tau never accomplished anything notable on their own due to a crippling lack of creativity. Humans must be in physical contact with an Ethereal or perhaps subjected to heavy doses of the pheromone in other ways to be sufficiently affected but aliens are affected merely by being in the vicinity of an Ethereal. Whether this is canon or not now is uncertain. It all probably is, seeing as it hasn’t been retconned/overwritten. Or GW forgot about it.

Putting it simply, there's an ongoing joke that the Tau are some of the most successful trolling performed in the history of mankind just by ''existing''; a case of the company installing them just to mix things up whilst at the same time keeping them surprisingly on-level.

The combination of the above fluff, however, paired with their highly advanced technology, generally "Asian" feel (their Fire Caste's combat doctrine is often reminiscent of Sun Tzu's "''Art of War''" - but derived from two distinct Tau hunting methods), use of [[Mecha|battlesuits]] (just [[Imperial Knight|like]] [[Dreadnought|the]] [[Titan (Warhammer 40,000)|Imperium]]), [[Hammerhead Gunship|heavy firepower]] which rivals that of the Imperial Guard, and one of the [[Fish of Fury|most broken tactics in tabletop 40K until it was finally fixed an edition later]] has conspired to make them very much hated (and by that we mean a source of butthurt) by a reasonable-sized population of the [[/tg/|40K fan populace]], and /tg/ has rightly dubbed the Tau [[Weeaboo]] (as much due to their Asian-ness as anything else) as a result (even when people can use the same logic to point to the Imperium's xenophobia, the fanatical worship of the God-Emperor, extensive use of Mecha and suicide attacks, use of suicide attacks as punishment for dishonour, and fondness for over-the-top dialogue in general and conclude that the Imperium of Man is Imperial Japan in Space). As a dark twist on this inherent Asian-ness, a thread concerning lack of grimdark fan fluff on Tau led to the creation of [[Sept V'iet]], the Viet Cong Tau.
[[Image:Tau fire warriors.jpg|490px|thumb|left|The [[Greater Good]]: translatable as [[Deal with it|"if you want to make an omelette, you gotta break some eggs."]]]]

And again in a case of much cultural confusion, the Tau are often considered [[Communism|communists]] (despite being a rigorous, hierarchical, near-eugenicist class society that would drive Marx into [[RAGE]]) due to their central philosophy of casting aside the self in favour of the Greater Good. This is partly because it's a nearly twenty year old meme by this point and memes that old are very stubborn about dying... and partly because we're a bunch of ignorant fucks. If anything the Tau more resemble the class system of Plato's ''Republic'' crossed with the caste system of India and [[Star_Trek#The_Federation|Star Trek's Federation]], and a little bit of facism as well (because they're the only ones in the entire galaxy who bother to try diplomacy with xenos rather than [[Exterminatus|exterminate]] them (partly because all but a few alien species are horrific space monsters that only a complete idiot would try to negotiate with)).

Even then, the Tau has more in common with the Imperium than the noblebright space hippie Feds; they adhere to a highly strict doctrine of eugenics, as [[Love Can Bloom|all forms of love, sex or breeding between different castes]] are, translated from Tau lexicon into Gothic, '''[[HERESY]]'''. The Tau also have an explicit merchant caste as well as a single unified currency which is something that the Imperium of man very much does not have along with a system of standardised wage labour which makes them actually more Capitalist than the still stuck in Feudal Economics Imperium. Contrast to the Craftworld Eldar who's society of post-scarcity voluntary labour actually is fully Communist, albeit there's still nobles entitled to bigger houses.

As well, the Tau treat their [[Tau#Tau_Member_Races|non-Tau comrades]] as second-class citizens with no say in the Tau government, and demand them to abandon their old culture and conform to a Tau Empire, basically becoming like everyone else. Ergo, the Tau, despite not being the exterminate-all-other-species kind of racist, are still an ethnocentric, aristocratic empire pretending to be a Federation, not unlike Britain during their 'tenure' as the rulers of India.

To double the weebiness but to greatly decrease the communism connection, the Tau are remarkably similar to war-time era Imperial Japan. Not in terms of military doctrine but in terms of its geopolitics. Like Imperial Japan they're a young power situated in the east, relatively far from most of their possible rivals' centres of power. Like Imperial Japan they have a seemingly nice enough doctrine in terms of rhetoric; "Greater Good" and "Co-Prosperity Sphere"; but in terms of practise what it means is that they want to replace the old empires in the region with their own. Like Imperial Japan they're at a significant disadvantage in terms of production power compared to their most serious rivals in the region, and hope to compensate for that by tactical superiority and winning big decisive battles to topple the old powers.

To further solidify the connections to Japan in the early 20th century, the Tau Empire even borrows some terminology, such as "spheres" of expansion, a firm belief that despite their grotesque material inferiority to their primary enemies the power of their ideals and their superior willpower shall overcome their enemies all, and a dogged insistence on picking fights it probably can't win. Imperial Japan knew that America alone had nearly twelve times the industrial power, with Britain having thrice Japan's military-industrial might, France just about matching theirs, and the Soviets having four times that, and even China; despite being a wartorn barely functional shithole, could be a quagmire for it. But Japan didn't give a shit because they thought that they were so awesome they could somehow get all these people to surrender through a combination of being better at war than their soft, mewling enemies and that they simply believed in their destiny to rule the waves more than anyone else did. Much like how the Tau is fully aware that the Imperium, the Orks, the Necrons, and the Tyranids could all squash them flat in a stand up fight, but believe this is immaterial because their belief in the greater good shall overcome all and they have mastered the ways of war while their foes are mired in ignorance.

What is for sure though is that, whatever part of the terribly suited to analysing politics outside of the modern era one-dimensional spectrum of political agenda they are on (probably wherever you'd put Imperial Japan during world war two), the Tau government is mainly oligarchical, with the vast majority of political power concentrated in the Ethereal caste. This is further driven home by the fact there is a Tau splinter faction led by one of their two best generals alive, Commander [[Farsight]] of the Farsight Enclaves, whose government is a non-caste society seemingly devoid of merchants, meritocratic semi-democracy. The problem is, until people stop dragging him out of his self-imposed exile to fight Tyranids, Orks, and other Tau, he's a dictator the way Optimus Prime is sometimes depicted. Farsight's government is one most certainly [[RAGE|NOT recognized by the Tau Empire]], who have finally gotten around to dispatching a fleet to silence them. <s>This, of course, is [[Advancing_the_Storyline|imminent plot stuff that will never happen]] because it's always the 41st millennium.</s> nope, GeeDubs ''finally'' decided to move the plot forward, thankfully. We still have yet to see the outcome of this fleet dispatch, though.

However, the new codex has HEAVILY downplayed their naiveté, bringing back the original codex mention that the Ethereals have officially declared some species "[[Exterminatus|lost causes]]" and that the [[Greater Good]] demands they be killed to the last.
*[[Orks]] were the first of the big players of 40k to get this treatment. They pretty much were the only serious competition Tau had before they discovered the Imperium, and it only took them a few weeks of study to realize the fact that Orks are beyond reason or sanity. They still have not realized that their encounters with Orks have merely been minute numbers of stragglers.
*[[Tyranids]] unsurprisingly ended up on "shoot on sight" list pretty much after the first contact. Like with Orks, the Tau are unaware of the small force of Tyranids they have experienced and that the main fleet they "destroyed" has since come back stronger.
*[[Eldar]] briefly were on the list too, owning this to the first contact being made by the Commorites, and not just any, but [[Urien Rakarth]] himself. It took some nuked Exodite world and Craftworld intervention for tau to realize that not all space-elves are insane rapists and scratch them off the list. Probably more encouraged by the Eldar effortlessly curbstomping them than actually carring that they shot the wrong Spelves.
*[[Space Marines]] seem to be entering the list as of the second Damocles war. The reason is not because it's impossible to reason with them, but because after some intense Water caste psychoanalysis and Nagi "mind-[[rape|ripping]]" they pretty much declared that astartes aren't ''people'' but merely a ''weapon'' and as such have no place in Tau'Va. Since this means they ignore the [[Blood Angels|artistic]], [[Thousand Sons|scholarly]], [[Word Bearers|philosophical]], and [[Ultramarines|administrative]] aspects of being Astartes intended to give them purpose after the Great Crusade ended the Tau are probably just scared shitless of Space Marines and the sheer inspiration their presence brings even off the battlefield.

To sum it up, the Tau Empire is still an expansionist empire prone to using military force, but far better than almost every other polity in the setting, as it permits others to exist with rather lenient standards, and isn't dedicated to the purposeful extinction of all other life in the galaxy. On the other hand, they don’t care if you’re some primitive feral species or a peaceful member of a species they have decided to be a lost cause. Also, as a result of surviving attacks from the major factions in the galaxy yet being blissfully unaware that those were merely tiny brushes or stragglers of vastly larger forces, the Tau believe they have proven they can truly hold their own in the galaxy against all the major players. As of Eighth Edition they were corrected quite painfully due to the opening of the Great Rift and the loss of most of their Fourth Sphere Expansion forces to a Warp rift, and following a massive Chaos invasion they have been forced to face the possibility that their empire might have bitten off more than it can chew.

Ironically, if their tech really is reverse-engineered Imperial tech (science-wise), it might not be heresy to... take it back.

==Military Doctrine==
[[Image:TauTyr2.jpg|right|500px|thumb|Close-quarters painting [[Drawfag|strikes again.]]]]
The Tau disdain [[Choppy|melee]] [[Rip and tear|combat]] in favour of [[Shooty|ranged combat]], which renders them instantaneously [[Matt Ward|less manly]] in the eyes of most of /tg/'s playerbase. The reasons behind this are complicated. Generally, Tau see hand to hand combat in warfare as an anachronism, which makes sense, considering their basic guns can rip apart tank side armour, and compared to almost all other major races Tau have less muscle strength and reaction speed, which makes them ineffective in melee even if they are trained.

Even the last reason alone is enough to avoid close combat, seeing as [[Necrons]] use similar logic, despite their [[Necron Warrior|Warriors]] and [[Necron Immortal|Immortals]] being much stronger and tougher, and actually highly trained in close combat, but equally as slow, though if the Necrons do want to get into melee, they're certainly not lacking in specialists. That said, Tau do practice martial arts, but only for ritual purposes - Fire Warrior trials and rites involve knives and swords, while Ethereals have a tradition of fighting non-lethal duels to settle disputes, using sharp bladed weapons no less, so they are often quite good with their fencing style, as [[Aun'Shi]] has shown to some unfortunate Orks.

Some people think Tau military doctrine has been hit hard with the same [[grimdark|stupidity]] nerf bat as every other fieldable army; every other faction has some reason for their material to be as limited as they would be in a fantasy setting, but the Tau have widespread education, unlike Men and Orks; reasonable access to production facilities relative to their population, unlike Necrons and Eldar; and are capable of coherent research and development, unlike Tyranids and Daemons.

For fluff reasons which have never been explained (the crunch reason is obvious), they have the same motif as every other army of equipment often being more valuable than the person wielding it, leading to most personnel being fielded with "inferior" equipment. The most obvious example of this is that they always, under whatever circumstance, field infantry in simple combat armour rather than some sort of battlesuit - its only advantage is having less bulk, as the Tau have a reason not to build larger transports to cope with the shitloads of battlesuits they could deploy instead.

This argument is analogous to saying that real-world militaries should only use armored vehicles and not have infantry, and says more about fa/tg/uy ignorance than Tau doctrine. The Tau likely practice economy of force, which has consequences both on and off the battlefield. Sending excessive amounts of force at a target is wasteful, as the excess firepower would be more useful elsewhere. If one only has a XV8 Battlesuits and no infantry, but a swarm of grots in a nearby pass needs to be taken out, they have no choice but to commit a very valuable unit to a task far beneath its worth. This is also an economic matter, as lower power units are cheaper and the Tau do not have an infinite supply of the rare materials needed to produce the strongest Battlesuits.

One could easily field a number of fire warriors for far less than the cost of a single battlesuit, and considering many foes will fall beneath "mere" infantry, any cost-aware faction would prefer the infantry's use over an expensive battlesuit. Similarly, when it comes to occupying or garrisoning territory, numbers of soldiers is significantly more important than quality of soldiers as they need to cover ground and establish a presence. In other words, they are the army who most resemble modern forces in terms of strategy, and mixed armies of infantry, armor and support elements are a good combination. And who the fuck can with a straight face call a pulse rifle and carapace grade armour "inferior equipment"? The view their equipment or doctrine is nerfed also ignores that armies have to replace lost and damaged equipment as well as actually get that equipment to the troops or they're absolutely fucked. An expensive army of battlesuits is lovely right until combat losses alongside wear and tear reach a point where the empires production can't keep up with losses or supply problems mean they don't reach the front (armies in 40k have been shown running low on ammo something far easier to produce and transport in large numbers than battlesuits). A army based around soldiers armed with "cheap" rifles and armour is a lot easier to produce and keep in the field even in the face of casualties or supply problems.

The Tau's superior [[Dakka|firepower]] is similar to that of the [[Imperial Guard]], but their strategy is different in that they tend to rely less on mass warfare and more on sophisticated technical support (drones, stealth technology, railguns), with an emphasis on tactical precision, mobility, and the initiative of individual squads of units, much like how modern warfare is waged (apparently if the Imperial Guard learned from Tau tacticians and fought with modern tactics instead of zergrushing everything then they would have been the most powerful army in the galaxy, but no, that ain't GRIMDARK and AWESOME enough [unless you're [[Lord Solar Macharius|Macharius]]]). Their military doctrine is not based on winning by attrition and/or throwing out quality tactics in favour of absorbing and dishing out heavy shocks in bloody epic clusterfucks like the Imperials, Orks and early World War II-era Soviet Russia. (Unless you count the later war "deep warfare", which is actually the combat doctrine the Tau ripped off. 40k really seems to like the Russians...)

Rather, they use infiltration and their sophisticated battlesuits to [[Anal Circumference|bypass enemy strong points and launch deep into their rear]], cutting supply lines and logistics, destroying headquarters and support units, leaving enemies cut off and functionally helpless. There are numerous examples of Tau literally starving and/or thirsting entire armies to death by cutting out their supply lines, while simultaneously harassing them with night raids, ambushes and air strikes to the point the survivors are leaderless, demoralized, out of ammo and fuel, and can barely stand due to exhaustion. The [[Imperial_Armour_Volume_Three:_The_Taros_Campaign#Volume_Three_-_The_Taros_Campaign|Taros]] campaign is a prime example of these tactics (and of the Imperium's strategic stupidity).

Of course, these kinds of tactics only work fine against more convenient armies like the Imperial Guard or Orks. When it comes to Space Marines and Eldar, who sport mostly aerial/warp/webway supply lines, operate as elite armies without obvious weak spots to exploit, have similar or superior tactical mobility and badass officers that can survive most assassination attempts, Tau lose huge parts of their usual advantages (but get the numerical superiority in return). Against utterly unconventional foes, like Tyranids, Daemons or Necrons... well, all times they faced such foes, Tau either devised some entirely new strategies, or lost horribly.

[[File:TauTyr.jpg|thumb|left|300px|90% of Tau [[dakka]] comes in the form of [[Plasma|pretty blue lights.]]]]
The Tau, again, boast some of the most powerful ranged weaponry on the tabletop game, and can crank out more concentrated firepower than any other faction with the lone exception of the Imperial Guard and maybe the orks if you only count number of bullets in the air, and even then, the Tau's weapons hit quite a bit harder. They have pathetic hand-to-hand combat skills, however, and so the Tau bolster this by using several inducted races (the [[Kroot]], Vespid, and even some [[Gue'vesa|humans cut off from the Imperium during the Damocles Crusade]]) to act as buffers against assault troops to allow Tau Fire Warrior teams and their heavy, long-ranged firepower to tear enemies apart. The most pivotal, and perhaps most infamous, part of the Tau army are their [[Battlesuit|Battlesuits]], which can mount multiple heavy weapon systems and provide excellent mobility to their pilots, all on a fairly durable unit.

They also have an extremely powerful navy, though not quite as formidable as the Imperium's, if largely because of number differences. Tau air units are among the best in the game, with aircraft superior or equal to Imperial Guard equivalents, including a stealth fighter, multipurpose heavy fighter, a superheavy fighter with guns that can one-shot a Titan, and their own [[Manta|Titan-equivalent]] (which is a small starship). Unlike the Imperium, they usually deploy swarms upon swarms of flyers, with only Orks, Tyranids, and Necrons able to rival them in numbers when things come to dogfights—kind of the way the Imperial fleets' atmospheric support craft were supposed to work if fleet officers weren't a bunch of assholes who do everything they can to provide as little air support as possible.

On defense, the Tau are a bit unusual: they leave only token garrisons at their colonies to protect them. These garrisons are intended for scouting rather than combat, avoiding engagement in order to observe and report on invaders using Pathfinders, scanning towers, and drones. Because the Tau have fairly powerful spacefleets and usually keep their forces within reasoned distance of potential hotspots, any potential threat can be quickly dealt with by organizing a hunter cadre to be sent to deal with the situation. For those of you who don't get it, it's Frederick the Great's "he who tries to protect everything protects nothing" strategy.

Of course, this strategy means Tau must have some worlds actually being heavily defended - and in fact they do. Sept worlds tend to be guarded by some nasty space stations and garrisoned by an unreasonable amounts of hunter cadres and auxiliary troops, which allows them to act as major defensive nodes from which response fleets are dispatched and to which evacuation fleets rally (think feudal Japan style castles from which commanders would send trained garrisons out to protect the lands around it from encroaching armies), and in case some really scary shit like an Imperial crusade or a Tyranid hive-fleet comes into the sept, it is on the sept world where the decisive battle is fought (See the First Damocles Crusade for an example of this tactic in action).

This has, however, backfired on occasion, since it does mean that the Tau garrisons are very vulnerable in the initial stages of an attack. It also makes them very vulnerable to Orphean War style rapid assaults where the attacker is advancing so quickly the defender doesn't even have time to relay the news that they're under attack to the rest of their army. While the Tau haven't yet faced something like the Maynarkh Dynasty, they are awfully close to the Sautekh Dynasty and Imotekh is a noted cantankerous asshole and egotistical conqueror.

A rare advantage the Tau have is their willingness to change military strategy. As examples, look at how they changed tactics in reaction to the [[Damocles Crusade]] by the Imperium of Man, and even built an entirely new space fleet to match humans in straight-on space fights, or their unusual but effective choice of switching to older weapons when dealing with [[Hive Fleet Gorgon]].

==Fleet==
In the old fluff, Tau used to have a reverse-engineered imperial warp drives, tuned to only skim the surface of the warp and bounce back to materium after a short while. New fluff on the other hand retconned that, by giving them what is called "slingshot drive" for their FTL, and from what little fluff we have on it, it looks like the actual warp drive (in the modern physics meaning, i.e. warped time-space bubble). The practical applications, however, are the same in both new and old fluff - Tau FTL is much slower than the Imperium's, but is predictable, reliable, and not affected by warp storms (a big deal, given Tau spent half of their history inside one). As a result, Tau are capable of building proper interstellar logistics lines, ones the Administratum can only dream of, but their strategic mobility is <s>lacking functionally superior to</s>...different compared to pretty much every other faction (even the non-Warp drive using FTL factions are different; the Necrons and Eldar teleport while the Tyranids bring their production power with them).

Additionally, Slingshot drives are rather big, heavy and power-hungry, even compared to the Warp drive (which takes up a 1/3rd of a smaller imperial ships). As a result, escort-class Tau spacecraft are built without FTL drives and are hooked to bigger ships for the purpose of interstellar travel, which basically make them equivalents of the Imperium's system monitor ships, with the same benefits (cheap, compact and too fast, powerful or durable for their size) without their major downside (being incapable of FTL flight). The Tau also have to concentrate their forces on an interplanetary scale; they can't throw a bunch of ships into a warzone from halfway across the galaxy as orks and humans can.
Tau empire have two fleets:
*Kor'Vatra, or "merchant fleet", is made of older modular ships that double as merchant and colony vessels (hence the name). One of their main shticks is huge arcs of fire for most gun batteries, with side batteries easily covering front arc, and nose batteries covering all but the stern - as a result, while Kor'vatra Ships may not have as much firepower as Imperial or Ork ones, they can focus more of it on one target. On the flip side, merchant ships while decently fast at sub-light, are not very agile, and must rely on escort wings and auxiliary fleets against more maneuverable foes. Even after the founding of Kor'Or'Vesh, Kor'Vatra still see a lot of military use, especially against the Imperium, <i>precisely</i> because it's regarded as non-military fleet, so Tau diplomats could tell their imperial colleagues "What battle cruisers on your orbit are you talking about? It's just our merchant vessels, moving goods to and from our trade missions".
*Kor'Or'Vesh, or "combat fleet" is a newer fleet, made for battling Imperium's fleet in straight up battle, after Kor'Vatra get run over during Damocles crusade. Made out of more compact, maneuverable and better armored ships, it may lack Kor'Vatra's wide arks of fire, but is superior in every other regard, and as Taros and second Damocles campaigns showed it is more then capable of fighting off humans even if outnumbered.
Both fleets use largely the same technologies - railguns as (by tau standard) short-ranged high damage gun batteries, ion cannons as long range beams (lance equivalent), and above all, their brokenly-powerful ordinance second only to Eldar ones (and available in far greater numbers) - Mantas, Barracudas and EMP drone-torpedoes reign supreme at extreme ranges, gaining Tau navy the same reputation their ground armies have. Because their ordinance is so powerful, most Tau ships tend towards carrier and torpedo boat archetype, and suffer horribly if enemy comes within macro-cannon or god-forbid boarding range (that is IF they manage to come that close).

==Non-combat Fluff==
[[File:Tau city.jpg|450px|thumb|right|Contrary to what [[Imperium of Man|some]] believe, what this picture shows might just be the future for the entire galaxy if the Tau [[Great Crusade|get their way.]]]]
The Tau were a new race/culture found by the Imperium of Man during their "slash and burn" exploration of their galactic neighborhood. The Tau were still pastoral, had just discovered flint tools and charcoal, and the Imperium had them scheduled for "[[Grimdark|routine cleansing]]" (Low Gothic for “ruthless genocide”) to make sure they never got off-world and developed into an entity capable of threatening humanity. Needless to say, that plan was promptly [[derp|fucked up]]. By an unfortunate (or fortunate, depending on your feelings towards a species' right to not be mercilessly exterminated for no reason whatsoever) coincidence which almost certainly involved the dickery of [[Tzeentch]] or [[Cegorach]] or [[The Deceiver|something]], a warp storm occluded the Tau homeworld, so nobody could get in or out. Since the Tau were virtually invisible in the warp, the warp storm didn't have much of an effect on them as they were immune to the influences of Chaos.

[[FAIL|The sector was labeled "lost to Chaos,"]] and cleansing was [[What|deferred indefinitely]]. Then [[Age of Apostasy|this shit]] happened, and almost all records about Tau were lost in the ensuring [[Rape|clusterfuck]] of civil war. Only the Adeptus Mechanicus still had records of this first contact when the storm died down 6,000 years later. The Damocles Crusade relocated the Tau, who were completely untouched by the warp storm and now using interstellar colony ships and pulse rifles. The extermination order still stood—it was just going to be much more difficult than the Imperium expected, seeing as the Tau, instead of [[C.S. Goto|throwing spears and rocks at their tanks]] and Space Marines, were now throwing [[ion cannon|ion charges]], [[plasma|plasma blasts]], and [[railgun|electromagnetically-accelerated hypervelocity projectiles]] at their tanks and Space Marines.

Tau history is pretty typical up through the iron-age: a knack for engineering, warfare between "urban" farmers and "barbarian" nomads, and unrestrained growth causing a series of plagues, leading to a dark age. Here's where things go sideways, though the Tau see it as the start of their endless Golden Age: the arrival of the Ethereals. Legend tells of a five-year siege at the castle of Fio'taun, with both sides starving and succumbing to disease, when two foreign Tau entered the battlefield. One went to the castle, the other to the barbarian tribes. Each of these Tau had a quiet grace and irresistible authority. In just a few hours, the castle was persuaded to open their gates, and the barbarians laid down their weapons, and both parties met to parley a truce.

These strange Tau called themselves "Ethereals," and stressed the importance of peace and understanding between all Tau. They described a "Greater Good" that each Tau must strive towards. Soon after, soon enough to seem simultaneous, more of these strange new Tau emerged across the continent with their message of peace and co-operation for all Tau. Their quiet authority was always respected, and their message of harmony was universally embraced. Wait a minute, [[God-Emperor of Mankind|I've seen this]] [[Great Crusade|historical pattern before]]....

Perhaps uniquely for the setting, Tau-human interactions bear the whiff of realpolitik. On the one hand, the Imperium wants to exterminate them ''eventually'', but the upper management generally realizes that the Tau are going to be a giant drain of resources and manpower to get rid of, given the stiff resistance they put up in [[Damocles Crusade|previous campaigns]] and their [[Riptide|uniformly]] [[railgun|advanced]] [[battlesuit|technology]]. Furthermore, they serve as a useful buffer state against various threats on the Eastern Fringe, from Orks and Chaos raiders to Tyranid hive fleets to alien forces the Imperium hasn't had (recorded) contact with. Their existence deflects danger from Imperial space, and in a place and time when the Imperium is [[Time of Ending|coming under attack from all sides]], that's more important than dogma.

This strategy is not unique to the Tau only though, as the Imperium allows countless other (much more dangerous) xeno empires to prosper in the Eastern Fringe to serve as an ablative shield against much nastier shit. Amongst those is (for example) the Charadon ork empire, which is older than the Imperium and spawns a Waaagh! or two per millennium (even with the routine warboss assasination raids that the Ultramarines make). Even after the emergence of the genius warboss Snagrod and his Waagh on Rynn no one cared to issue a crusade against them. So yeah, the Tau empire is not even close to being spotted by the High Lords, not to mention recognized as a threat dangerous enough to actually do something about.

Conversely, the Tau have realized just how massive an undertaking expanding through the entire universe would really be, and are taking it slow. They mostly absorb Imperial buffer worlds stripped of manpower and armament in the face of massive redeployments to face other threats, offering the Empire's protection in return for annexation and outright conquering the places that don't take the deal. The Tau have claimed that they are engaging in this sort of aggressive behavior because ''someone's'' going to [[Tyranids|gobble]] those settlements up sooner or later, and if ''they'' don't do it, then whoever does won't be [[Exterminatus|nearly as nice about it]]. While baldly self-serving, that logic is...well, mostly correct, really.

There's no lost love between the Imperium and the Tau, but open full-scale war is probably unlikely in the near-future.

And then the Second Damocles Crusade happened.... even the imperium isn't that stupid, so this almost certainly involves that tricky dick Tzeench trying to stop the greater good from ruining all his plans. ...Or nurgle...or, well any of the ruinous powers really. Or that ancient scheming old sperg [[Eldrad]], for that matter.

Looking at the new galactic map, where the Tau are now sandwiched between their own eye of terror and a Necron dynasty, they are soon to be fucked.

=== Castes ===
[[File:Commander HawkEye.jpg|thumb|290px|right|<s>Join the Greater Good, lose your virginity to a hot alien babe!</s> Unapproved of sexual contact is an offence to the greater good Gue'La. Now get back to work or you won't get your overtime pay! ]]
Tau society after the arrival of Ethereals was organized into castes; everyone with a place, and a place for everyone. [[Love Can Bloom|Interbreeding between castes and Xenos races]] is one of the most severe crimes in the Empire, in other words, [[Heresy]]. This was outlawed by the [[Ethereal]]s presumably to preserve the biological differences between castes, and as part of this effort they have taken over the practice of sex entirely. Tau society has been manipulated so that Tau do not form romantic bonds of a long-lasting nature and do not even consider sex to be anything other than a state-mandated act meant only, like everything else, to serve society and the Greater Good. In essence, Tau are conditioned to never have sex until and unless their superiors say they are worth breeding.

Their superiors pick their breeding partners (the Tau get NO input into this) and the couple basically spends a few days off from work screwing around before going their separate ways to never see each other again. If a Tau did somehow get over their social conditioning and thought of sex as something more than a mandated duty, they'd be [[Blam|punished/killed for illegal activities/perversion]]. An Imperial genetor's report in the fourth edition Tau codex observes the presence of synthetic proteins in Tau internal organs and suggests them as evidence that their evolution has been accelerated, though he might have been confused by synthetic proteins that the Tau were given. [[/tg/]] seems to be under the strong impression that they are mammals, as you can see in the picture further down the page, despite the complete implausibility of this theory. The frequent [[/d/|sexualization]] of the Tau by fa/tg/uys is a mystery to many, but clearly not all. [[PROMOTIONS|Not nearly enough]], in fact.

==== {{anchor|Fire|Fire Caste}} Shas (Fire) ====
The '''Fire Caste''' consists of the various [[Fire Warrior|warriors]] of the Tau Empire. The miniatures of a Tau army in a [[Warhammer 40,000]] game are almost exclusively Fire Caste. Other castes think Shas are overly-aggressive hotheads due to their tendency to solve all problems by applying more plasma (when Tau encountered other sentient species, Fire Caste representatives immediately voted to hunt down and exterminate them, just like they hunted down dangerous local life forms on the other world they colonized), although for Humans and Eldar, who's history knows numerous [[Wyches|kinky]], [[Haemonculus|horrid]], [[World_Eaters|Earthshatteringly mad]], [[Night_Lords|batshit insane]], [[Blood Angels|bloodthirsty]] individuals and groups, mention of the "Aggressively Hotheaded" Tau would end up with them collectively pointing fingers and laughing at them. On the other hand, it also shows how calm and disciplined other castes are.

They are taller than Earth Caste Tau, and physically stronger than the Air and Water Castes, though still shorter and weaker than a typical Human. They pretty much compensate for this by giving their basic Fire Warrior a [[pulse rifle]], which is sort of like an automatic sniper-[[plasma]] gun, and employ heavily armed and sophisticated battlesuits for their elite infantry. Oh yeah, and [[Railgun]]s. Company -sized Tau forces are called "Hunter Cadres".

==== {{anchor|Earth|Earth Caste}} Fio (Earth) ====
The '''Earth Caste''' are the laborers and engineers; they are the "civilians" of Tau society. Their appearance can vary widely, though other Tau would describe them as "plain." They all have a stoic outlook, with little ambition other than to excel in their career of choice and work for the Greater Good. Unlike the Imperial worker classes, whose quality of life generally ''starts'' at working 14-hour days seven days a week while living off of dried, recycled dung chips and goes [[Such is life on Volg|''downhill from there'']], the Earth caste is mostly concerned with technological planning and engineering.

They have robots to do the grunt work. The Farsight Enclaves field some Earth Caste pilots for their battlesuits, demonstrating their more flexible caste systems and/or their desperation for manpower. Doing so makes them ''even worse'' in close-combat than Tau already are, but they make up for it with technical training and tweaks to the suits' software and mechanics, re-rolling missed shots and equipment failures.

==== {{anchor|Air|Air Caste}} Kor (Air) ====
The '''Air Caste''' are the intermediaries between Tau. In more primitive times they served as messengers and couriers, and sometimes scouts/explorers, gliding on membranous anatomical surfaces through T'au's atmosphere. When the Tau started exploring offworld, it was the Air Caste that took charge of the vessels traveling between the stars. Now the Air Caste are the Tau stellar navy/airforce/mailmen, piloting the Empire's various carriers, warships, and emissary cruisers. Air caste Tau tend to be tall and slender like runners or dancers, and this is frequently exaggerated by the years the Tau navy spends in low-gravity.

They are much less likely to be eaten by [[daemon]]s due to a faulty Geller Field than their Imperial equivalents, but only because their ships are much slower, using a "slingshot drive" to temporarily enter the Warp and bounce back into real space. Despite their slender stature and lack of muscle mass, Air caste pilots are extremely resistant to G-force, making them excellent void and atmospheric fighter pilots (simultaneously, as small Tau voidcraft also double as atmospheric craft).

==== {{anchor|Water|Water Caste}} Por (Water) ====
The '''Water Caste''' are the emissaries to non-Tau. They are diplomats, merchants, civil servants. The most open-minded Tau can be found among the Water caste, with some even showing individual ambition (but still for the greater good of the Tau Empire). When a new culture is encountered, the Water caste are sent in first to negotiate. If talks break down, the Water caste are withdrawn from the area and it's time for the Fire Caste to then start negotiating with pulse weapon fire. Also, unlike their Imperial equivalents in bureaucracy, the [[Administratum]], they are brisk, efficient, and very good at their jobs. No dumping valuable ammo on an uninhabited dust world because no one signed the paperwork not to.

It's a less known fact that Pors also run the Tau intelligence and espionage network, and Por'Os and Por'Els from this branch are pretty much Tau Inquisitors except more competent, much saner, and not nearly as good at kicking asses personally. As of the second Damocles Crusade the Imperium has designated the Water caste as a primary threat above any other Tau caste, as their subterfuge, diplomacy and propaganda has cost the Imperium more worlds and manpower than the Fire and Air caste's military prowess combined, and they even managed to totally outplay the Inquisition on its own field, which royally pissed them off.

==== {{anchor|Ethereal|Ethereal Caste}} Aun (Ethereal) ====
The '''Ethereal Caste''' are basically the philosopher-kings described by Plato in "The Republic". They are selfless and always focused on what is best for the Greater Good ("Tau'va") for all Tau and every Tau without exception. The Ethereals are inspirational to all Tau caste members, and merely being near one will inspire a Tau soldier, engineer, pilot, or diplomat to work harder.

In the case of the Fire Caste, some Ethereals accompany hunter cadres in battle during important deployments so as to better lead/inspire the troops, which works because all Tau in the combat zone will fight to their bitter deaths. They also seem to have semi-magical powers (don't ask how they work, none of the Tau know themselves) that allow Tau around them to do special things, like running while shooting. The [[Adeptus Mechanicus]] theorizes that the respect the Ethereal Caste gets from all other Tau is caused by a pheromone. <b>ALL GLORY TO THE HYPNOTAU......</b>.
Also, ''[[Xenology]]'' relates a story from a major, insectoid race called the [[Q'Orl]] which alleges that the [[Eldar]] stole one of their queens. Given that these queens have a magic, yellow, diamond-shaped sack that produces mind-control pheromones…well, let's just say the characters in the story figure it out quickly enough. There is a theory that the Ethereals themselves are also affected by their own pheromones, which could explain why they're so selfless and uncorrupted despite their absolute power (although being uncorrupted no longer seems to apply after 7th/8th edition).

This can also be supported by the (old as fuck and likely retconned) novelization of [[Warhammer_40,000:_Fire_Warrior|Fire Warrior]], where the Ethereal character has a pretty level head and chipper demeanor despite having been [[Anal_Circumference|repeatedly captured and tortured by both the Inquisition and Chaos, watching his diplomatic retinue chopped up by a Chaos Lord, and mind-raped by said Chaos Lord all in the span of roughly two days.]] Either he's a stoic old motherfucker, or he's just too busy tripping his blue balls on his own pheromones to give a shit.

8th ed has a particularly interesting story in it and it proves without a shadow of a doubt: the Ethereal caste does use some kind of mind-altering substance or influence on the Tau. During a meeting with Commander O'Ryn and Aun'Va (who is a solid hologram controlled by an AI at this point) in the planet of Junica, their location was ambushed by Chaos forces and Aun'Va (or the AI acting like Aun'Va) ordered O'Ryn to send her forces on what's essentially a suicide mission. O'Ryn, not seeing the point of throwing her and her soldiers' lives at such a hopeless battle, actually ''defied'' the command of an ethereal (and the space pope himself, no less) and retreated. It could've been an interesting and pretty terrifying critique of how manipulative a totalitarian system can be and that the Ethereals don't shy away from anything to keep the people in line. But no, it was explained with mind control, which is way lazier and honestly way less terrifying.

O'Ryn was eventually declared a renegade and Farsight took her in, but it does indeed prove that the unflinching and unquestioning loyalty and fanaticism that the ethereals' physical presence inspire on nearby Tau aren't due to their charisma or the Tau's indoctrination, and instead on something more sinister. To put this into perspective: O'Ryn has been the first Tau since Farsight to actively defy an ethereal's command and the main reason she was able to do so was because she was speaking to an AI-controlled drone, instead of the actual space pope.

===Tau Names===
Tau have ridiculously long, detailed and actually meaningful names. Their names contain their caste, rank, birth sept, and one or more nicknames earned by them through the course of their lives. Fluff does say that they ''do'' have birth names, but those are only used before tau earn at least one appropriate nickname, as a name given to them by comrades is considered more valuable than one just chosen by random at their birth. The nickname part and it's importance surprisingly is actually taken from the Roman culture, which is weird, given most Tau culture tend to be based on China and Japan (except for their social and government structures which are copied almost verbatim from Plato's Republic).

Also, do note the lack of last names, which is expected, since Tau society pretty much have no institute of a family, with children being raised in a centralized facilities apart from their parents. As tau grow, move through ranks and achieve respect of his comrades his name changes appropriately, switching the rank part, adding new nicknames and sometimes dropping the old and outdated ones. For example, when Farsight was still a lowly fire warrior, his name was '''Shas'La Vior'La Shoh''' (Fire Caste Private of the Hot-Blooded sept Inner Light), and at the "present days" '''Shas'O Vior'La Shovah Kais Mont'yr''' (Fire Caste Commander of the Hot-Blooded sept Farsight Skillful Blooded). How the fuck Tau bureaucracy is able to keep track of their population with their names constantly changing is a mystery, but it seems they have no problem with that, probably because they just track ID numbers when names are too much of an issue like most sane people who work with databases.

For the sake of convenience Tau often use shortened versions of names, almost always dropping the sept part and secondary nicknames, and if speaking within one caste the caste part too, so in the case of Farsight other fire warriors could refer to him as O'Shovah, while for example an Ethereal would call him Shas'O'Shovah (assuming Farsight allows this given his seething hatred of Ethereals, he's the type who'd force them to use his full name out of spite). Humans and other non-Tau often get this system wrong and shorten the names in a ways that make little sense: for example, Imperium's Taros invasion force thought the Taros' chief Ethereal's name was Aun'El, which was only his caste and rank, and as the book was mostly written from the Imperium's standpoint, we still don't know what was his actual name.

One final stroke of Tau naming, is that as they abandon their true (birth) names it makes them even more resistant to sorcery and daemonic powers that often require target's true name to amplify their effect or even make the spell work at all.

===Psychic/Chaos Defenses===
Tau are an entire <s>race</s> species (with five races) of psychic blunts, they cannot produce psykers and have limited innate resistance to some forms of psychic powers and daemonic bullshit. People often mistake this resistance to outright invulnerability, but in truth it's more akin to camouflage - Tau souls are so dim they are indistinguishable from the spirits of non-sapients at best, and at most times they even blend in the psychic background of inanimate objects. This may have something to do with how unemotional tau are, as some of the more passionate subjects in the fluff had been slightly affected by warp shenanigans like faint whispers and slight feelings of "wrongness" in places where humans creep out and try to run away immediately, while more calm and collected tau hadn't noticed anything strange. If for example a telepath tries to mind-rape a tau or a daemon tries to posses a tau he'd find it hard to find a soul to target, but if he manages to find it there would be even less resistance than with regular humans. Sadly while this trait is often shown in the fluff, it does not affect tau crunch in any way.

This innate defense is further strengthened by the Greater Good philosophy deeply indoctrinated into each Tau from childhood and (allegedly) reinforced by a subtle mind control (“allegedly” Tau fans ignore their own fluff (like that pulse rifles are not plasma weapons) explaining about the Ethereals’ mind-influencing pheromones, fluff with enough detail it explains that humans are affected in physical contact and other species just need to be in the vicinity of an Ethereal. We can assume the Tau likely spread it in air, water, and food.). Tau'Va being the antithesis of all the creeds of Chaos makes Tau all but immune to its temptations, and only a single Tau has ever actually fallen to Chaos, the Water Caste member Water Spider who was possessed by a Daemon of Tzeentch. That being said, the Tau have only just been exposed to the more material horrors of the galaxy; should they become jaded and start losing faith in the Greater Good (as inferred with giving up on indoctrinating certain species), well, that would be an entirely different situation. Their allies, including the Kroot, have been known to go all-in with Chaos worship, although Tau seldom take culture from their allied races.

8th Ed is here, and has confirmed that the Tau aren't immune to Chaos, just slightly difficult for Daemons to spot. When the Tau started the 4th Sphere Expansion with their new warp drives: they didn't take a note from the Imperials' tech and failed to invent the [[Gellar Field]] too, meaning they were fully vulnerable to the Warp's denizens. The entire experience was hilarious. First was the unpredictability of their warp drives (known as "slipstream technology" to them) that caused most of their expeditionary fleet to be destroyed due to unleashing massive tears in the fabric of reality, [[lulz|while being broadcasted to the Tau sept worlds, causing the Ethereals to rapidly evacuate their bowels as they scramble to censor the event to the wider populace.]] Those that weren't immediately torn up by the warp rifts, were sucked into the Warp where a vast majority was either destroyed after drifting in the more unsavory parts of the Warp, or the various daemons mucking about.

Contact was lost, but the Tau managed to find the survivors later, nestled into several worlds that were the original target for conquest. The Tau that survived however, were acting weird. Some of them started shoving off the Greater Good, while some worshiped a voice that they claim to be the Greater Good itself (which may or may not be a warp entity), while some were outright driven insane. A disturbing trend about them however, is their total [[Imperium|xenophobia and brutality]]. Any non-Tau who wasn't driven off from the 4th Sphere colonies were murdered for [[Chaos God|something]] that was telling the survivors that the auxiliaries were the reason for their loss and torment due to their more powerful connection to the Warp, so killing all non-Tau was the only way to ensure the survival of the Greater Good.

That being said, they're still hard for Daemons to see, considering that the Fourth Sphere dove into the Warp unprotected and "merely" got off with plain Chaos corruption when most people who try that shit critfails their [[anal circumference]] roll and either gets torn apart by daemon cocks or becomes [[Chaos Spawn|an Unnameable Beast]]. But this event does still prove that the Chaos Gods can still influence the Tau with enough warp exposure, so it wouldn't be surprising if a few of them started going bughouse-nuts and began carving 8-pointed stars on their persons in the future. Especially with virtually the entire [[Death Guard]] and a large force of the [[Thousand Sons]] heading straight for the wormhole that links the Fourth Sphere colonies to the center of the Empire...

==Alliances==
{{MattWard}}
[[File:Illus4.jpg|280px|right|thumb|Unfortunately for some [[Slaanesh|deviants]] [[Extra Heresy|and heretical elements on]] [[/tg/]]. [[Not as Planned|This is what an actual canon Tau Female looks like.]] No boobs, no curves, no ass, no redeeming qualities other than having a face of your grandmother and the nose of a mutilated vag. Know the alien. Hate the alien. Purge the alien. The Emperor Protects! <s>This is an Ethereal though, so the other castes should be fair game.</s>]]
In 6th edition, Tau are notable for being one of two factions (the other being Imperial Guard) who can ally with anyone except for 'Nids. Yes, this includes both Chaos Space Marines and Chaos Daemons, although, according to the Farsight Enclaves supplement, <s>Farsight is one of the few Tau (maybe the only one ''period'') who actually understands the existence of Chaos, so the average Tau would consider them to be just another kind of alien.</s> Farsight rebelled because the Ethereals understand the existence of Chaos on some level, but keep it suppressed from the general populace so they're not entirely screwed. [[Emperor|Which sounds vaguely familiar]]. It is probably going to end [[Horus Heresy|about as well]], too (although due to cultural differences likely in it's own distinct way); all of this is, of course, assuming that the 'nids don't NOM everything before the Tau get the opportunity to fuck their own shit up.

Their current level of naïveté leads to a few... ''interesting'' alliances, to say the least.

First off, Tau ''can'' ally with [[Ork]]s, even though fluff-wise they are viewed as enemies of the Greater Good to be purged wherever encountered. Smaller Ork warbands (mostly [[Blood Axes]]) frequently act as mercenaries, of course, so the Tau might use them in that capacity. Plus, there might be fluff changes coming up (most notably, it was rumored that the [[Gretchin Revolutionary Committee]] would return in the new Orks codex; they, of course, would get along quite well with the Tau).

They are also battle brothers with both the Space Marines and Eldar, which has caused a large amount of headscratching on /tg/. The Eldar make a modicum of sense; after all, the Eldar most likely had a hand in their synthetic evolution and the creation of the Ethereals, and the Eldar are well known for being expert manipulators. A Tau-Space Marine alliance, though, would be odd, to say the least, since Tau and Space Marines are always going at it in the [[fluff]]. Of course, a minor [[Space Marine Chapter|chapter]] could always find an alliance with the Tau, or even [[Heresy|join the Greater Good]], but that seems far-fetched at best. Old fluff from back in the 3rd edition codex tells a story of a Tau commander letting an Apothecary remove the aul glands from dead Marines, establishing that the Tau are honourable warriors in the minds of this particular chapter. Isn't too hard to guess that someone at GW felt the battle brothers thing was a bit of a head-desk move, so they tried to fix it.

The weirdest part, though, is that Tau ''aren't'' Battle Brothers with the Imperial Guard, despite (or maybe because of) the existence of [[Gue'vesa]] (Imperial Guard defectors).

7th edition corrected all of this for the Tau, making them only battle brothers with themselves and certain allies of convenience, like Necrons and the Eldar, while the rest are desperate allies or, in the case of daemons and 'Nids, allies of the apocalypse. This effectively "fixes" the issue from the point of view of a butthurt puritan while still allowing for those who bought Tau models to include them as allies in their games.

8th edition totally destroyed any chance of Tau having allies in matched play games. Taudar is dead, thank fuck.

==Tau Member Races==
[[File:Dynamic entry by majesticchicken.jpg|right|thumb|550px|Look up fuckers! You're invited to the latest imperial party and we're not taking "no" for an answer!]]
The Tau are the only faction that willingly accept other races into their ranks. Typically, the races are extended a hand from the Water Caste first, and if they still pose a problem or otherwise refuse to be reasoned with, the Fire Warriors are sent in. It should be noted that tau usually are not in haste of annexing the world, and if the aliens don't want to join right now but aren't immediately hostile and open to trade, Water Caste would slowly but surely convert them into a Greater Good to the point that one day they themselves would ask to join the Empire. The species, when annexed or conquered, are usually allowed to keep their planet, but must answer to the authority of the local Ethereal and possibly the local Shas'o. Most of them are fluff and don't show up on the tabletop, but it would get a little ridiculous if you could purport to play a 'single' 40k race that included, like, twelve different races.

* Demiurg - <s>[[Squats]] reborn.</s> NOT ANYMORE the Squats are back and not Demiurg at all! They are a race of space-faring miners specializing in ionic weaponry who serve the Tau with their engineering and mining abilities. They also serve as an example of something the Imperium will never do: <s>save dead codex races (Well, okay, they're sort of saved...).</s> They make an appearance in Battlefleet Gothic: Armada though, so that's nice.
* Galgs - Frog/Toad People who are regularly hired as mercenaries. No other information available. Probably [[Lizardmen#Slann|Slann]] In Space.
* [[Gue'vesa]] - Humans who have not only defected to the Tau, but chosen to take up arms and fight alongside them to serve the Greater Good. Rules for them are found in [[Forge World|Forge World's]] Imperial Armour Volume 3. (If the current trend goes on we may see Sisters join up with the Tau, <s>which might be an improvement for the Sisters.)</s>{{BLAM}}{{BLAM|HERESY!}}
* Hrenian - Alien mercenaries employed for their skills as light infantry. No other information available. Probably [[Lizardmen#Skinks|Skinks]] In Space.
* Ji'atrix - A spacefaring race. No other information available. (Dammit, GW [[Writefag|writefags]].)
* [[Kroot]] - Predatory gene-assimilating avian humanoids. They are the first alien race to be actively recruited by the Tau as mercenaries, and are so regularly hired that they have officially progressed to being considered Auxiliaries of the Tau forces.
* [[Vespid|Mal'kor]] - Insectoid aliens, also known as Vespids, who are native to a gas giant planet within the Tau Empire. Serve as Auxiliaries.
* Morralian - Also known as "Deathsworn". No other information available.
* [[Nicassar]] - A voidfaring race of [[psyker]]s and the only psychically-gifted species in the Tau Empire. The Tau have carefully hidden them away from the Imperium due to their (actually justifiable) psyker-phobia. Were the second alien species to join the Greater Good.
* Ranghon - No information available.
* [[Tarellian]] - These guys are basically [[Lizardmen#Saurus|Saurus]] IIIIN SPAAAAACE!!!!!! Not really part of the Empire, but rather mercenaries who will gladly fight humans and Tyranids on the cheap since the Imperium virus-bombed their home world and the Tyranids nommed their biggest colony.
* Poctroon - The first sapient species to be found by the Tau, [[wikipedia:Siege of Fort Pitt|they were "accidentally" driven extinct by Tau smallpox]], and their planet just by coincidence was a great place to set a Sept World.
* Nagi - Brain worms that, due to their horrific appearance and inability to communicate, were attacked by the Fire Caste. They managed to sort it out, though, and now they work with the Ethereals as advisors (because having brain worms about as "advisors" isn't a bad idea or anything). They have been shown in a few books so far, and were involved in a "mind-rip" (guess outright calling it "rape" was too much) of a space marine POW, while being so self-righteous and smug about their mental superiority they could give Eldar a run for their money. Apparently they can also at least perceive the Warp (which they call "extra-dimensional space"), and probably manipulate it as well, and know enough about it to outright refuse to go anywhere near demonically-tainted Agrellan when the Tau invaded it.
* Ji'atrices, Morralians, or Ranghons are probably other Warhammer Fantasy Races In Space, such as [[Lizardmen#Kroxigor|Kroxigors]] or Trolls, given the overall tendency of the Tau to incorporate Fantasy races missing from 40k.

The usually genocidal actions of the other races, most notably the [[Imperium]], also serve as a motivating factor for less-powerful races to join the Tau. While the Tau do seem a minor threat to the Imperium now, if the current policy continues, there will be more and more races joining up with the them if for no other reason than avoiding [[Exterminatus|extermination]]. Of course, the Tau are just coming to realize how vast and powerful the Imperium really is, and while a lot of their member races really ''are'' the victims of crazy, evil, fascist extermination protocols, there's always the chance that someone responsible for a "Hell World" or "Nightmare World" might join up, and the damage might be done before they realize their mistake...,

==In a Nutshell==
;'''The Stated Reason Why People Hate Tau'''
Weeaboo space confucianists (Asian Commies)—not grimdark enough.
;'''The ''Real'' Reason Why People Hate Tau'''
Until the edition update, this would, most assuredly, be [[Fish of Fury]]. Fuck, even most Tau players felt this was bullshit. Post-edition update, it was that certain [[Matt Ward|undesirables]] felt that they were trying to take the mantle of the 40K universe's "rightful" Imperial protagonists. And because they are not [[Choppa|choppy]] enough. And then 6th Edition codex came, and Tau became one of the shootiest armies in the shootiest edition ever, not to mention their ability to bitchslap cheesmongers, having straight counters against any of the Wardex bullshit. When the 7th edition came out they became overpowered AF and they took the title as the chedder cheese of Warhammer.
More generally, the Tau battle philosophy is "deny your opponent the chance to interact with you," which is a good philosophy for real soldiers but can make for frustrating or uninteresting gameplay.
;'''A Real Reason Why People Like Tau'''
The one race that isn't being a wall of dicks. If the Tau are trolling done by Games Workshop, then the target of said trolling was any fatbeard that needs a constant supply of grimdark to stay alive. Of course, the mind-influencing pheromones they use to conquer new worlds and their psycho-indoctrination mass re-education facilities will just have to be ignored if you don't want destroy your wishful thinking for a half-way decent faction to exist in 40k. But people have always been good at ignoring shit that doesn't fit into their perceived image of something.
;'''Another Real Reason Why People Like Tau'''
Unlike many other Races in 40k the Tau are capable of fitting into many other Sci-fi Universes without much Problems. Such as Star trek where they would be at home along side other Peaceful yet also Tyrannical Factions like the Federation. Compared to the Necrons or Eldar which would be both Roflstomps and completely different from all other groups in that Universe. (Unless it [[Doctor Who|Doctor Who]]).
;'''The Real Reason Why People Play Tau'''
Arguably have the most powerful guns in the game. Often twin-linked. Often on cool-looking robot battlesuits. [[meme|Also markerlights]]. Also [[Riptide|RAPETIDE]]. Tau players may also have a tendency towards sadism.
;'''A Solid Reason People Don't Play Tau'''
They're fucking expensive. Seriously. On a points-per-pound level, they cost more than any other (plastic) army. This is doubly true if you like battlesuits, but of course you do because you're playing Tau.
;'''Helping Necrons? Or are they Necrontyr descendants?'''
An often overlooked issue is that Tau have almost no warp signatures, just like Necrons, hate Warpspawns and Warp in general (despite the fact that in 6E they can work with them...I just...I don't...WAAAARD!!!), just like Necrons, have the exact same skull shape, stature and short lives, and the overwhelming need for Technology and beam weapons, JUST LIKE NECRONS. [[GW]] may have planned a race that simply prepares a pacified, multiracial galaxy for Necrons to feast upon, supported by Ethereals that have a C'tan phase blade. Then there is a reference of "dark seed in east" by the Deceiver, so the tricky C'tan might give Tzeentch the finger in the [[JUST AS PLANNED]] competition. Or maybe GW just has so little creativity that they simply made a new civ conforming to an Old One's standards without knowing it. Given that recent murmurs have suggested that something absolutely massive is in the works at GW, ''anything'' could be possible, though past experience has led us to believe that it will simply be a Tau wearing a silly [[hat]].

==TL;DR==
<s>The good guys</S>
High-tech, Mech-loving alien race who are the ''least'' [[grimdark]] of factions. Can't melee for shit but can blow you back to the stone age with ranged weaponry if you have the misfortune of being downrange. You will either love them or hate them because of all this, and many neckbeards do feel the [[butthurt]]. For some reason Tau females are [[/d/|awkwardly sexualized]] by a non-insignificant minority of fa/tg/uys, which has shown up in some draw- and writefaggotry. As the saying goes: "You can't spell TAUNT without TAU."

== Warhammer Fantasy ==
Unlike most other factions in 40k, Tau have no clear antecedent from [[Warhammer Fantasy]]. Some think the anime influences and rapid industrialization/militarization point towards Nippon; others feel the caste system might be related to the Kingdom of Ind. However, neither faction has ever been explored in great detail (or any detail at all), so it's impossible to say whether Tau are similar to those factions; instead, we must compare to the real-world equivalents of the Old World nations. Slightly more controversially, there are elements of Cathay (which is the Anglicized word for China back in the British Empire heyday, so yes) in the Tau. Cathay has been described as being technologically advanced (at least on par with the Empire), including terra-cotta automaton warriors (which the Chinese definitely used to make to pay homage to the First Chinese Emperor's over inflated ego, more than a millennia ago), although such comparison is stated by some to have [[Skub|already been implemented in the characterization of the Eldar and thus, is considered as ''seriously'' stretching up a notch.]]

More recently, some have connected the Tau and their subject races to other factions in Fantasy. The rapid evolution of the Kroot and their overall savagery is (somewhat) similar to the Gors of the Beastmen (although the Beastmen are in the 40k universe themselves). The Empire also shares the xenos-friendly viewpoint of the Tau, although they're not expansionistic, and decidedly less concerned with a unified government structure so long as everyone pays their taxes, for better or for worse. Others compare them to dwarves: dwarves don't use Chaos magic, are short, technologically advanced, kinda casty and blue (understood in many countries as "hopelessly drunk") basicly all the time. Tau don't use Chaos warp magic, are short, technologically advanced, very casty and blue all the time (in regards to skin colour). Both also get seriously grudgy and angry when you piss them off.

==Trivia==
[[File:Tau Ripoff.jpeg|thumb|right|300px|FOR THE [[Blood Ravens|GREATER THEFT]]!]]
* Some have said that Tau resemble the protagonist KYNE from the Amiga video game Brataccas, which was released in 1986. Tau were first added to Warhammer 40k in late 2001. Some would dismiss this as coincidence, but Games Workshop has a long history of ripping off designs from other games; [[Beastmen]] are [[Broo]] from [[Glorantha]], very large chunks of 40k are a little too similar to [[Judge Dredd]], and all of the Greater Daemon model designs are stolen from early [[Dungeons & Dragons]]. These properties are understandable as Games Workshop was still selling games of those IPs when Warhammer was first created, but Brataccas is an obscure game from a forgotten system that was quite forgettable even at release, even if Amiga games tended to get fantastic cover art. This being said another of GW's early products was also puzzles of of this style of '70's/'80's Sci-Fi art. The Tau cast system does resemble the Protoss caste from [[Starcraft]], which predates the release of the Tau by 3 years... You have the Templar (Fire/Air Castes) Judicators (Ethereals + Water Castes) and Khalai (Earth Caste). In addition to a rogue sub-caste in the Dark Templar (Farsight Enclaves). This is Ironic considering that GW originally was making a deal with Blizzard to make games based on their properties. GW asked too much/Blizzard didn't like the terms and left... to make Warcraft and Starcraft. Just think, we <s>COULD have had a Warhammer Fantasy RTS</s> (Total War: Warhammer exists now) and World of Warhammer Fantasy Battle MMO. Starcraft would have become a Rogue Trader RTS. It was probably a mistake on GW's part, as they REALLY missed out. Stealing the Tau from the Protoss was probably done because GW was still salty.
* Tau are technically canon to the Marvel Comics universe, as the series Venom: Space Knight repeatedly used Tau vehicles for aliens in the scenery. In fact, they have the balls to even keep the Tau Sept symbol! Also, you can see what appears to be a Eldar tank, as well as a Necron. The irony of the ripoff masters Games Workshop getting ripped off is juicy, even more so when its realized that lawsuit-happy Games Workshop (who literally tried to copyright "pauldrons" while they plagiarized Eldar from Tolkien and had some contention between [[Malekith|two very similar Dark Elf characters of theirs]]) couldn't do shit about it because Marvel is owned by Disney, and nobody beats The Mouse™. (except Marvel/Disney settled out of court rather than risk the wrath of the Ordo Legalitus)

Plague Wars

2019-10-09T18:53:10Z

2600:1006:B15F:8F83:C4A6:EFF5:645A:4441: /* The aftermath: spring cleaning Ultramar */

{{Topquote|Nurgle's blessings will be released into the atmosphere ensuring Complete. Global. Saturation.|Plague Champion Wesker to Ultramarine Captain Redfield during the war.}}

The Plague Wars were a series of conflicts between the forces of the Plague God [[Nurgle]], led by the Traitor [[Primarch]] [[Mortarion]], and the Imperium of Man, particularly the [[Ultramarines]] [[Chapter]] and descendants, led by the Lord Commander of the Imperium, [[Roboute Guilliman]]. The conflict arose from Nurgle's ambition to expand his domains to the [[Ultramar]] planets, taking advantage of the then ongoing [[Indomitus Crusade]] and the fact that the [[Cicatrix Maledictum]] had obscured the realm from regular warp travel. The start of this campaign marked the end of the Indomitus Crusade, and it is the one of the major background events for the Dark Imperium novel and the Fate of Konor campaign.

==Nurgle starts seeding his new garden==
And isn't '''THAT''' just the most horrifically disgusting title you've ever read. In~uen~do!

Way back before the [[13th Black Crusade]] had started, the Chaos God Nurgle was trying to absorb the Ultramar Realm to his Garden. In small amounts, he promoted and favoured small cults of pestilence and corruption to grow and prosper, unbeknownst to imperial authorities. Starting from neighboring Imperial systems to the galactic North of Ultramar, now known as the [[Scourge Stars]], small nurglite incursions tried to spread the plagues to the rest of the systems, but these attacks were of small effect. It wouldn't be until the start of the 13th Black Crusade and Roboute Guilliman's Indomitus Crusade that the scenario would be right for a nurglite campaign to become a real threat.

The main forces leading the nurglite forces were the [[Death Guard]] Legion, led by the Traitor Primarch Mortarion and [[Typhus]], plus a major force of daemons under the Great Unclean One [[Ku'Gath]]. These forces, however, could not launch a direct invasion on the core planets of Ultramar, due to its massive defenses and fortifications, not to mention the infights between the three chaos leaders, who each wanted to gain Nurgle's favours all for themselves alone. Thus, they started a campaign of fear and attrition on nearby worlds, attacking and corrupting nearby agri worlds, forge worlds and hive worlds. Taking advantage of the situation, nurglite forces launched plague after plague unto these planets, ranging from zombie plagues to nurglings exploding from the inside of the victim's body, which only meant their forces grew bigger and bigger.

When news of escalated aggression made it to Roboute Guilliman, he dissolved the Indomitus Crusade and launched his forces to reclaim and rescue the Ultramar Realm.

==The Imperial Counterassault and the other Chaos Gods ruin Nurgle's fun==
After Guilliman arrived and surveyed the direction of the war, he decided to first try and cut Chaos reinforcements from their origin, since the forces of Nurgle were still too great in number for the arriving imperial fleet. Cutting chaos forces from the Scourge Stars meant that reinforcements would cease to arrive, a hard blow for the nurglite armies. Aiming to destroy the source of the undead armies, Guilliman's forces attacked and destroyed most of the Greater Daemons and Daemon Engines, stopping the enemies's cannon fodder from appearing.

After a massive series of imperial counterattacks, the remaining Chaos Gods took that opportunity to invade the Scourge Stars, which meant that the Death Guard and associates were forced to retreat to the Scourge Stars to defend and fortify the Plaguefather's foothold in realspace.

==The aftermath: spring cleaning Ultramar==
After the war was over, dozens of planets in the Ultramar Realm were horribly contaminated by plagues. The imperial authorities oversaw the purging and rebuilding of these systems. Which goes to show how good the Imperium is at dealing with Chaos that it can cleanse and rebuild worlds taken by Nurgle. Or any of those tumor freaks. Once that was over, Ultramarine forces launched a series of attacks to nearby chaos-controlled systems. The Death Guard, still in realspace and once finished with the defense of their worlds, decided to take a stroll through [[Tau]] controlled territory, which became the most threatening campaign for the tau since Damocles Crusade. More accurately, the Tau ran into them and lost contact with that entire expansion sphere. Which surprised no one.

{{topquote|What fool would plan to defeat their enemy by dying forever themselves?|Asdrubael Vect}}

'''Ynnead''' is the [[Eldar]] god of the dead and may or may not be the reincarnation of David Bowie. Ha! [[Just as planned|Bet you can't unsee that now!!!!]] ([[Cegorach|Cegorach pls]])). He was previously more of a concept than an actual being, representative of what may be the last hope of the Eldar against their eternal enemy, [[Slaanesh]] - and possibly Chaos in its entirety. The Eldar expect him to save them from Slaanesh. Whether by absorbing their souls or killing Slaanesh we don’t know, though the Eldar expect him to kill the Warp tumor. Those with more sense (i.e. the fandom) question the wisdom of sending a being made of Eldar Souls to fight something that specializes in eating Eldar souls. Just food for thought.

== Overview ==
When Slaanesh was born, she devoured most of the Eldar race, and their souls, and most of their gods, and basically caused a lot of things to get badly screwed up, making a terrible mess in the toilet afterwards that the Eldar were forced to mop up. The crap on the wall that won't scrub off was that the surviving Eldar found Slaanesh was constantly hungering for their souls, laying in wait for the moment when any member of their race died to completely consume them. In the past the Eldar believed that when they died, their soul would be reincarnated - with Slaanesh's coming, the Eldar's ability to reincarnate disappeared. To save themselves from this fate, the Craftworld Eldar use [[spiritstone]]s to trap their souls upon death. The spiritstone is then used to intern the soul within the Infinity Circuit of a Craftworld, next to a carefully placed egg timer, where the soul is free to roam around and commingle with the other Eldar souls of the Craftworld.

As more souls over time have been added to the infinity circuits, the Eldar [[Farseer]]s perceived something stirring from this collection of souls; this was Ynnead, a god formed from untainted Eldar souls and the power of [[Asuryan]], the king of the Eldar gods, who passed on his power to the Farseers of the Eldar before he was devoured by Slaanesh. The Farseers believed that when the last Craftworld Eldar dies, Ynnead will be fully born and will rise up to cast down Slaanesh, destroying him/her/it forever. It's unknown whether this would have been feasible or not considering Slaanesh's immense power, but Ynnead represented the Eldar race's last, best hope for a better future, and so all their efforts went toward making him as strong as possible.

Worship of Ynnead was, and likely remains, pretty controversial among the Aeldari, as would be expected of xenos modeled on the "dying elder race" shtick. Death is literally his entire purpose and portfolio, and the species that alternately worships and reviles him is coming increasingly closer to extinction - about as permanent of a death as you can get in this universe. [[Grimdark|Their last and best hope is essentially a gamble involving the soul of every single Eldar, alive or dead, on the off chance that they ''might'' be rid of Slannesh forever, and if that fails...]]

Those who accept Ynnead have the following point of view: Ynnead is the [[Eldar]] god of the dead. Or at least he will be, as he is currently being created. He is in godly limbo at the moment while the Eldar try to amass enough pure souls, or at least souls that have overcome petty desires, in the various [[Craftworld]]s' [[Infinity Circuit]]s which are bonded together by the Eternal Matrix that links all the Infinity circuits and World Spirits together through the Webway, to give him enough mojo to become a proper god.

With the release of the Gathering Storm, it turns out that the Ynnead is [[Emprah|anathema]] to the Chaos Gods and they are actually afraid of it - yeah, and Khorne wears high heels. On the other hand, Slaanesh has already been put on a bus in Age of Sigmar (Never mind he's getting some new stuff already) and Ynnead is a pretty good way to put Slaanesh on a bus in 40k too.

Other Aeldari see the worshipers of Ynnead as a misguided [[Heresy|heretical]] death cult who are risking the souls of the Aeldari race on a gamble. It also doesn’t help that the Yncarne bears more than a passing resemblance to Slaanesh.[https://www.warhammer-community.com/2018/09/30/24th-sept-grim-dark-corners-the-aeldari-pantheongw-homepage-post-2-gw-homepage-post-3/ 1]

Basically, Ynnead is the Eldar's last hope against [[Slaanesh]]. '''Ynnead''' is the [[Eldar]] god of the dead and may or may not be the reincarnation of David Bowie. He's alive (for a given value) and active now, but this is new fluff and as always in WH40k the Eldars' plan did [[Not As Planned|not survive]] contact with reality.

Slaanesh was born out of unbridled hedonism, giving them the theme of extreme pleasure. Ynnead is born out of the dead post-fall Eldar who are vengeful but still optimistic stuck-ups, so Ynnead would theoretically be born out of the Eldar's [[Khorne|vengeance]] and [[Tzeentch|hopes]] for a better tomorrow. Assuming it follows the same process as Slaanesh; Ynnead probably won't go rogue and will follow the main purpose of its creation. Probably.

Could the Eldar have simply had a bunch of Farseers, Warlocks, and Exarchs of each Path commit ritual suicide to reincarnate as an Eldar-Emperor being like the ancient human shaman did in outdated fluff? Probably, but these are Eldar. Their whole schtick is being cowardly pussy-tards. They would probably be too afraid of failing and being eaten to take such a chance. Or worse, it succeeds inside Slaanesh, further strengthening the abomination. That sounds about right for 40K.

Something to consider: Ynnead is a very different god then any other active entity in the setting. All of the other gods are immortal beings of perpetual nature. They are always focused on the concept of being endless, be it stagnation, warfare, evolution or excess. Only The Emperor shares a base concept with Ynnead, which is the concept of finality. Ynnead is the god of Death, and death is by its very concept a mortal thing, making it impossible for the Chaos gods to comprehend. So few demons are truly destroyed that the ruinous powers don’t actually view the concept beyond something mortals do in their spare time, and facing mortality would be such an alien concept that it would make them fear its existence. Ynnead was able to negate the position of Slaanesh, the disease of nurgle, the sorceries of tzeench and stop the senseless conflict of khorne. It’s existence is the possibility of ending them, and so they fear what they cannot understand. Ynnead May be small now but if it ever reaches a higher strength, the Chaos gods will have major problems.

==The Gathering Storm==
Surprise! Instead of sucking up all the dead Eldar souls, Ynnead is prematurely "born" during the 13th Black Crusade following the fall of [[Cadia]]. [[Eldrad|Eldrad Ulthran]] attempts to summon him early by stealing the fossilized bodies of all the dead Farseers from all the Craftworlds, and conducting an elaborate ritual on a crystal moon. It gets fucked up by the [[Deathwatch]], and only a tiny fraction of Ynnead enters the Materium.

After searching through space, this fragment discovers [[Yvraine]]. Due to her history, she was considered the ultimate expression of being Eldar because apparently the true Eldar are supposed to travel all the paths of life, even the dark ones. With her is the [[Visarch]], a former [[Exarch]] of the Dire Avengers who trained Yvraine and had his heart broken when she chose to leave rather than succeed him. He ended up sneaking into Comorragh, pretended to be an [[Incubi|Incubus]], and fought his way to Yvraine after she unlocked the power of '''The Sword of Sorrows''', one of the severed fingers of [[Morai-Heg]] forged into a sword by [[Vaul]]. The Visarch would later get his own sweet croneblade, '''The Sword of Silence''', when it was pulled from the heart of Craftworld Biel-Tan.

Together, Yvraine and the Visarch become the prophets of Ynnead, preaching that not ALL the Eldar have to die for Ynnead to be born. This ends up fracturing Eldar society at all levels, and Biel-Tan ends up tearing itself apart over whether or not this is actually Eldar [[heresy]]. The destruction of Biel-Tan causes all kinds of Warp holes to tear themselves into existence around the ruins, and Ynnead births an Avatar through them known as the Yncarne (get the pun?), the one-horned ghost-fire model that's been making the rounds in photos of the latest White Dwarf.

Yvraine, Visarch, and Yncarne are now gathering [[Ynnari|an army of all the branches of the Eldar race]] who believe they can fight Chaos without all having to hara-kiri, while those who don't believe in Ynnead are preparing to kill all the heretics for daring to alter the fate of the Eldar. Eldrad himself is imprisoned and placed on trial by the Eldar Inquisition, because he's not Eldar enough, and proposed, after his failure to birth Ynnead, allying with the [[Imperium of Man]] to defeat Chaos once and for all. Even if the other Eldar don't like the idea of becoming best buddies with the Imperium they still reluctantly agreed that they are still the best of a bad bunch, what with the other options being either the [[Orks]] or [[Tau]] both of who are either too "young" (translated as to naïve and inexperienced to face the forces of Chaos and lack the incredible power of any major faction) or simply too uncooperative and uncouth to be allied with (basically ever alien that isn’t a devoted Imperial citizen ordered to cooperate), that didn't stop Yvraine from helping to resurrect [[Roboute Guilliman]], so perhaps an actual alliance may be possible.

It may also be that Ynnead simply disagrees with the stupidity of not allying with the only faction both willing and able and actively doing something against chaos. It could also be possible that once Guilliman gets in charge the Imperium will stop killing everything that isn't human and start killing everything that is a demon with them. That would be stupid and doom the Imperium, though, because the whole reason the Imperium spends its time killing aliens is that countless alien species keep attacking them constantly. So, if the Imperium stopped fighting them, it would be quickly overwhelmed.

==The Croneswords==
The five Croneswords are legendary shapeshifting blades said to have been formed from the five broken fingers of the severed hand of [[Morai-Heg]]. According to legend, the five blades are imbued with a connection to Ynnead, and will reveal themselves when the unborn god begins to stir, where the blades will find their way into the right hands and lead to the eventual salvation of the Eldar race.

The blades are as follows:
*'''Kha-vir, the Sword of Sorrows''' - The first awakened blade, appeared to [[Yvraine]] while in the fighting pits of Commoragh
*'''Asu-var, the Sword of Silent Screams''' - Was pulled out of the Biel-Tan Infinity Circuit before the craftworld broke apart, is now held by the [[Visarch]]
*'''Vilith-zhar, the Sword of Souls''' - Currently wielded by the [[Yncarne]], was recovered from Belial IV.
*'''The Spear of Twilight''' - Relic weapon of the [[Iyanden]] [[Craftworld]], said to drain the life of its wielder. Had been wielded by Prince [[Yriel]] since the invasion of [[Hive Fleet Kraken]], it's power awakened after Yriel fell to [[Nurgle]] daemons and resurrected him.
*The fifth blade has not been found, but is currently being sought on the [[Necron]] infested [[Exodite World]] of Agarimethea by '''Nuadhu Fireheart''' of Craftworld [[Saim-Hann]]. ''(potentially a returned special character for the next codex?)''

Imperial Navy

2019-10-08T20:25:27Z

2600:1006:B15F:8F83:C4A6:EFF5:645A:4441: /* Battleship */

[[File:imperialnavy1.jpg|400px|thumb||Cathedrals IN SPEHSS!]]

{{Topquote|When you began, you couldn’t have possessed enough bones for the whole ship. It would look stupid with a few dozen skeletons nailed to the walls. So, how do you start? Do you save up enough bodies for a corridor at a time, or put them away until you have enough to decorate the entire vessel?’|Jain Zar,-Storm of Silence}}

{{Topquote|By my faith, may the light of the Emperor spread to the farthest star. By my duty, the galaxy will belong to the righteous. By my actions, the Imperial Navy shall be honoured and remembered on Holy Terra. For the Emperor of Mankind, AND FOR THE BATTLEFLEET GOTHIC!|Imperial Navy Captain Abridal, shorty before his blaze of glory that ultimately stopped the 12th Black Crusade and saved billions of Imperial lives.}}

The '''Imperial Navy''' is one of the main branches of the [[Imperium of Man|Imperial]] military in [[Warhammer 40,000]] (although very little of the Navy actually appears in the tabletop game). They are also one of the main factions in the beloved spin-off game [[Battlefleet Gothic]].

Unlike the [[Imperial Guard]], who get killed in the <s>thousands</s> <s>millions</s> billions every day, the Imperial Navy rarely suffers that many casualties. This is because, unlike the [[lasgun|flashlight]] used by Guardsmen, the main weapon of the Navy is a giant, heavily-armed, heavily-armored battleship that puts other races' spaceships to shame (well, except [[Necrons]]). These ships are also [[Awesome|massive, flying, Gothic cathedrals]].

Depending on how you look at it (and who you're looking at), the officers of the Navy are either wealthy cowards or badass gentlemen. In either case, their ships have crews numbering the hundreds of thousands or even millions (we're not kidding when we say that each ship has its own language(s) and culture(s)), since the Imperial Navy doesn't understand how auto-loaders work, so loading a gun requires thousands of slaves running on treadmills. Of course, this might be the fault of [[Adeptus Mechanicus|a certain other branch of the Imperium, who, coincidentally, ''do'' have working auto-loaders on their ships]]. In any case, [[Grimdark|the Imperium has found it cheaper and ''more effective'' to use manpower because they have ''that many people'' to throw at even the tiniest of problems.]] Except that the cost of hundreds of thousands or even millions of chain-gangs adds up over centuries and millennia whereas maintenance for the machinery would basically amount to "apply oil while chanting". Of course, for a major officer, most days simply require him to press a button and blow something up, then go back to drinking his tea. Oh, and ''maybe'' scramble the ground-support flyers, if he's feeling charitable that day.

Note that, back in the [[Great Crusade]], the Imperial Guard and Imperial Navy were one and the same, operating under the far-less-badass name of "Imperial Army." However, thanks to the [[Horus Heresy]], the two got split up, so that a single military commander couldn't control too many forces; a Guard commander isn't able to get off any given planet without the Navy, and the Navy isn't able to conduct wars (and, you know, occupy territory) without the Guard. You'd think that this enforced mutual co-dependence would make them collaborate, but [[grimdark|of course]], despite how much they need each other, the two bicker constantly, which, in fact, may be the reason for all the [[fail|stupidity]] the 40k universe is saddled with, at least on the military front.

==Types of Ships==
The Imperial Navy has four types of ships they hide their cowardly asses in. The main ships are battleships, cruisers, escorts, and fighters
Each ship can also be classified by its weaponry, and role in the battlefleet:
*'''Basic:''' Jack of All Trades ships, due to having multiples weapons types, and not being specialized into any. Lunar class cruisers are the prime example, having macrobateries, lances & torpedoes.
*'''Lance-boats:''' Ships that focus into Lance weaponry, used for long-range focused attacks, especially against small ships & unshielded ones. Rarer as they have a weakness to Void Shields and require better drives due to the power requirements of the lances.
*'''Ordnance-boat:''' Opposite of the Lance-boat, replaces Lances with more Macrobatteries, focusing mostly into medium & short range brawls against enemy ships. Usually this is because they need extra power due to mounting a Nova Cannon or having power-hungry macrobatteries such as Plasma Cannons.
*'''Carrier:''' The red-haired stepchild of the Navy. Replaces the Lances with Launch Bays and is disliked by most Admirals due to the stigma against Attack Craft, although it is because the Traitors & Chaos pawns focused on raiding & striking fast, so with enemy fleets focused on long range attack (Lances, laser, and attack craft)plus Chaos likes them more because they can fill the bays with Assault Boats, the Imperial Navy might have got that stigma of seeing too many Chaos carriers raiding & pillaging imperial planets & so started dislike them. Some Carriers are also made from wrecked cruisers of other types, in which case damaged broadside weapons are ripped out and replaced by launch bays.
*'''Torpedo-boat:''' Originally an experiment for escort ships to overrun enemy vessel crews using boarding torpedoes, it was doomed to failure as the targets were either too nimble or too big. The Imperial Navy kept a few as Missile Destroyers.

===[[Imperial Navy Battleship|Battleship]]===
Supposedly rare, but every Grand Marshal and High Admiral has at least one and often several or even dozens to hide in because GW is completely and hopelessly inconsistent with fleet sizes, though as of late it seems that GW is leaning towards big fleets and big armies when it gives numbers. Bonus points if that coward is also Chaos. The biggest heaviest hitters available, these things are like actual medieval cathedrals in that the grandchildren of the workers who start building them get to live to see their completion. Fuckheug, lots (and lots, and lots) of guns and most can deploy fighters and bombers.
*'''Ordnance-boats:'''
**'''Retribution:''' Packing all gun batteries, the ship can devastate an entire continent in one broadside, but for some reason cannot destroy a hive city or fort with [[void shields]] (...why is this surprising? Shields are...shields) - [[What|or in some cases, ones without any shields at all]]; either that or GW was just pulling another [[Derp|Michael Bay]] out of their asses again since, they have no idea how [[Herp|consistency works, let alone basic physics.]] Of course, considering the Dark Angels fortress-monastery and the huge chunk of land surrounding it survived the bombardment which turned Caliban into a bunch of space dust, it is perfectly reasonable that something that merely glasses half a continent would not destroy a void shielded city or other major fortification. If anything, this provides a degree of insight into why land battles in 40k are so massive in the first place. Because orbital artillery doesn't have many targets of opportunity it is actually capable of exploiting without tearing the planet to pieces.
**'''Invincible:''' An interesting class, dubbed a 'fast battleship', these were designed to chase down xenos and chaos raiders, and then use them to make the vast, empty tracts of space more interesting by filling it with their enemies' debris fields. This type of battleship combines the firepower of a ''Retribution'' with the speed of a ''Dauntless''. The problem with this is the general incompetence of Imperial tacticians. It looks exactly like a ''Retribution'' and has the guns to match, so it must be one, right? NO. They excelled at the role they were designed for, but throw them into gunfights against dedicated battleships, and these things tended to come apart easier than wet cardboard, earning them the nickname 'Kisher's Kombustibles' and the scorn of many admirals. Admirals who ignored the fact that the reports detailing the introduction of the ship and how to best use it (it's tactics also included in the Tactica Imperialis) explicitly state not to use it on a gun-line and that it is for fast-ship interdiction. The ship's Commissars must be particularly incompetent to let this slide as in the Guard the generals would be executed quickly for such incompetence. Of course, these are also the Commissars who do nothing when troop transports' escorts frequently run off to fight while the transports lose a significant percentage of their ships. Perhaps if they would actually enforce their orders to stay with the transports, the Imperium would have won most of the campaigns it has lost. Given that they still often win even with a fraction of their beginning ground forces actually managing to make landfall. [[Grimdark|Because they have THAT many men to throw at the enemy.]]
***Much like the Chalice-class of Battlecruisers, the Invincibles are a big reference to the real life Battlecruisers of World War 1, especially with the term "Kisher's Kombustibles" (real life Battlecruisers were referred to as "Fisher's Combustibles") and the fact that three blew up in a single battle (referencing Jutland).
*'''Lance-boat:'''
**'''Apocalypse:''' One of the oldest ship designs (predating the ''Retribution'', which is also one of the oldest ship designs), this ship packs a lot of [[lances]] and a [[Nova Cannon]]. Good for taking out lots of smaller sized ships with massed lance fire. It's also described in fluff as being able to cripple anything up to a cruiser with a single, concentrated broadside. They're fairly rare, since the Imperium doesn't know how to build them anymore, and the ones still operating are so old, their weapons systems have degraded permanently, forcing them to fire their lances at only a fraction of their full power. Shares all the disadvantages of a ''Gothic''-class cruiser.
***Despite the fluff stating that the Apocalypse and Oberon classes are unique in that they lack figure-heads, the artwork and [[Crunch|models]] [[Derp|give them one anyway.]]
**'''Victory:''' Possibly an attempt to recreate the ''Apocalypse'' class, the ''Victory'' is basically a ''Retribution'' with a bunch of lances replacing its broadside cannons, and a Nova Cannon instead of torpedoes. Has the range that fluff states the ''Apocalypses'' once had, but lacks the same level of firepower. Effective at sniping, and hilarious when used against escort heavy fleets.
**'''Desolator:''' A ridiculously old design. Designed to emphasize range and carries Torpedos, Broadside Lances and Dorsal Macrobatteries. Like most keel-built ships, the Desolators ended up mothballed or went traitor.
*'''Carrier:'''
**'''Emperor:''' The "standard" battleship of the 40k 'verse, the ship has multiple fighter decks and weapons batteries. Unfortunately, most commanders like to use this ship as a hideout, causing the lack of sufficient air support in the ground wars even though the Navy's atmospheric aircraft are completely different from its much bigger space based strike craft. Tabletop-wise, its status as the official battleship of Battlefleet Gothic doesn't stop it from losing carrier duels against the Chaos equivalent.
***Ironically, the idea of the Emperor being the standard battleship conflicts with the fluff about the Navy hating Carriers. Go figure. Except it doesnt. Because the Imperial Navy isnt fond of carrier ships, but that doesnt mean they dont use them; So if you were an imperial admiral, would you choose to get multiple smaller carriers, at the cost of having less ship-of-the-line on your fleet? Or would you instead get a 8+ kilometer battleship with four city-sized hangar bays, having higher detection, and being capable of helping your fleet & any warzone in multiple ways (Not just void warfare, but also ground support in planet invasions, or logistical support) without the need of going too close to the enemy? Its no wonder the Emperor Class is so popular & useful in the Imperial Navy, looking at this way, in reality, the Emperor class goes well precisely on the conventional Imperial doctrine because of this reason. Despite the (idiotic) distaste Admirals have for strike craft, they will use still use them out of simple utility and they figure they might as well get something that can do more at the same time.
**'''Nemesis:''' The super-carrier of the Imperial Navy. It has SIX flight decks (the size of towns or small cities, each), more than any other ship in the galaxy. But because of Rule of Cool, it is incredibly rare since the Navy captains prefer to get up close broadside their enemies, or actually rather because all of the ships in this class were just ships modified from Emperor class ships in one particular war, because they were damaged or otherwise. Naturally, the Navy never considers making them based on the Invincible instead (the Invincible was mass-produced).
**'''Desecrator:''' The carrier variant of the Desolator. Replaces half the Broadside Lances with Landing Bays. Shared the same fate as its sister class and is now only seen in Chaos fleets. Traitorous despite its clearly pious and Emperor-loving name.
**'''Despoiler:''' Oh boy, where do we start? The Despoiler-class came about after the cogboys discovered plans for a carrier on Barbarus. The catch? Well, Barbarus is the former homeworld of the [[Death Guard]], and the plans were for the same class of ship that the [[Terminus Est]] is a part of. Showing a complete lack of common sense, the Imperial Navy decided to build ships of this class, only for them all to go traitor due to the class's inherent [[Gellar Field]] flaws. [[Fail|Oops]]. The Despoilers at first don't appear to be that unique, as they have Dorsal Lances and Broadside Landing Bays and Weapons Batteries. Their difference is that, like the Terminus Est, they managed to have a Prow Landing Bay as well.
***Despite being a new class, GW fucked up their fluff and had [[Rogal Dorn]] disappear aboard a Despoiler, [[What|5000 years before the class was created]]. Note this class was actually already named "Despoiler-class" by the Imperium. Yet, they were ''surprised'' the things went traitor. Wow. Also, after fixing the Gellar Field problem, the Imperium still decided not to build more, which was stupid since there was no longer a reason not to. I get not wanting to chance it, but beggars can't be choosers.
*'''Other:'''
**'''[[Gloriana-class_Battleship|Gloriana]]:''' Massive, terrifying and capable of decimating entire fleets on their own, these were the personal flagships of the Primarchs during the Great Crusade. Very few, if any, are still around in the Imperium in M41, though a few such as Horus's flagship ''[[Vengeful Spirit]]'' are still tooling around inside the Eye of Terror. Because they were dickheads, the [[Alpha Legion]] had two, creatively named the ''Alpha'' and the ''Beta''. Interestingly, the Ultramarines have one, the ''[[Macragge's Honour]]'', but didn't [[derp|fucking]] use it, the whole fucking time until [[Roboute Guilliman]] returned. It shows up again in ''Dark Imperium,'' with the Smurfs having stolen it back from the Red Corsairs, which at least is fucking funny even if it makes no sense. The Imperial Fist had the ''Eternal Crusader'', but it was never their flagship since the [[Phalanx]] is so much better, so [[Rogal Dorn]] gave it to the [[Black Templars]] in the [[Second Founding]]. The Emperor is known to have had at least one, called the ''Bucephalus'' (also the name of the horse of Alexander the Great... coincidence?), which he ditched after upgrading to an enormous golden space palace called ''Imperator Somnium'' for the sole purpose of flying him back to Terra to retire. Wait, did Emps just see the Phalanx and decide to build his own bigger better version?! [[Eldrad|DICK]].
**'''Oberon:''' The mixed-breed bastard of the Imperial Navy. It has [[lances]], fighter bays, and weapon batteries. Its a powerful ship... <s>when fighting foes half its size</s> "Newer" fluff says the Oberon is rare, but a complete success in making a ship capable of killing anything it comes across, alone. Unfortunately, fluff also says a ridiculously low number of these (apparently) powerful ships were made (like, 3 or so). Then again: only four Iowa class battleships ships were built (technically 6, but 2 were scrapped before completion), and we know HOW to build them. It makes sense in a way. Attack craft can cripple an enemy's main weapons and engines and likely ultimately damage the power transfer from generators to void shields. Combined with macro-batteries hammering away and the enemy's weakened ability to maintain its shields would cause them to drop much quicker than usual. Then the city-sized lance-batteries rip the enemy in half. If used against enemy escorts to support attacks on large enemy ships like battleships and grandcruisers, this would work extremely well to the point an Oberon would likely become a priority target for enemy ships.

===[[Imperial Navy Grand Cruiser|Grand Cruiser]]===
Only slightly weaker and less powerful than Battleships, Grand Cruisers were the weird middle-child of actual Line Ships (that really were the mainstay of the fleet back then) and Cruisers in the ancient Imperium. Built primarily with autonomy in mind, those were reserved for the most daring expeditions in the uncharted regions, conducted both by Imperial Army and Rogue Traders. Nowadays most of them run on archeotech that is barely understood and hard to repair with current Imperial knowledge. These grand ships are often used as flagships in lieu of extremely rare Battleships. Basically, they are the quintessential Battlecruisers; tougher and deadlier than Cruisers and yet more mobile than Battleships.
*'''Basic'''
**'''Vengeance/Furious:''' The granddaddy of "modern" Imperial warships. The ''Vengeance'' was the winner of a GW-sponsored ship design contest, and was originally known as the ''Furious''. Highlights include heavy shielding and armour (though lacking the prow armour of later designs), as well as both lances and long range weapons batteries, making this the sniper of the Imperium's Grand Cruisers.
**'''Repulsive:''' Originally named the Corinus Class, before being renamed after many fell to Chaos by an overly literal Mechanicum designation. Whilst the Repulsive Grand Cruisers are exceedingly maneuverable heavy warships (and therefore exceedingly useful because they can fill a hole in the Imperial tactical lineup), they are considered a cursed class due to the majority of them falling to chaos, [[Fail|which unfortunately was the result of experimental warp drives which occasionally interfered with the Gellar Field (OMGWTFBBQTIME)]]. Only the Emperor knows what kind of complete moron would deploy ships equipped with that. The ones that remain in Imperial control are kept mothballed in reserve fleets and segmentum fortresses (imagine giant glass boxes with 'In Case of Emergency, Break Glass' signs). It doesn't say anything about their warp drives being swapped out for something that isn't shitty or perhaps a completed and no longer experimental version of their own. Not that you want AdMechs tear off your head for tinkering with their sacred templates, on the other hand.
*'''Ordnance-boat:'''
**'''Avenger:''' The short range brawler of the Imperium's Grand Cruisers, it's a ''Vengeance'' with only macrobatteries (kilometres of Macrobattery broadsides). Intended to break the line of battle like Nelson's ships at Trafalgar, while suffering from the lack of an armored prow. Unfortunately line-breaking is quite a dangerous role for any ship, even a Grand Cruiser that excels at doing it, and so not many exist in the 41st Millennium. Those that have survived are known for being exceedingly reliable and faithful; it takes a lot of damage or mistreatment to cause these noble vessels to give trouble. If you spoke with members of the Imperium (both members of the public and the navy), this is the vessel they would think of if you asked them about Grand Cruisers. Now, if only the Imperium realized a slower but more heavily armored and shielded ship would fare better in its role.
*'''Lance-boat:'''
**'''Executor:''' The sniper of the Vengeances, the Executor replaces its Broadside Macrobatteries with even more Lances. Unfortunately, the last remaining Imperial Executors decided to act retarded and chase a fleet into the Eye of Terror, meaning that all of the ships are chaos aligned now.
*'''Carrier:'''
**'''Exorcist:''' A ''Vengeance'' that has carrier bays in place of lances. Useful in providing carrier support to any Imperial fleet. As a bonus, being Grand Cuisers mean they can outrun anything except battleships to save their vulnerable carrier self while their attack craft are away. Originally designed for extended operations alone on the Frontiers of Imperial Space, either on Patrol or by exploring into the unknown, the Exorcist developed quite a reputation for 'boldly going where no man has gone before'. Whilst not many remain in Imperial Service due to maintenance difficulties, they still find use in the hands of Rogue Traders who need vessels capable of long cruises and of defending themselves against anything they might encounter. So much for maintenance difficulties.
**'''Retaliator:''' A mix of a Repulsive and a Vengeance, but as a Carrier. Has Lances, Launch Bays and Macrobatteries on its Broadsides. Unfortunately, it has the Repulsive's tendency to go traitor.

===[[Imperial Navy Battlecruiser|Battlecruiser]]===
What do you do when you forget how to maintain an entire category of heavy warships? You build a new bunch of heavy warships, with simpler technology.

Battlecruisers are basically upgunned cruisers, with more weapons (usually adding dorsal weapons and some armor), and are intended to fill the gap between true battleships, which are rare, and normal cruisers, which tend to die really easily to the ancient Chaos cruisers and grand cruisers. Battle cruisers were tried in real life as some way to combine battleship firepower or armor and cruiser speed. They did not always work, and much like reality these things have their share of problems. Chaos operates their own versions known as Heavy Cruisers. In real life, the accepted successful form of a battlecruiser is between a heavy cruiser and a battleship; it can kill anything it can catch and it can outrun anything that can kill it (usually only an enemy battleship). After its teething years it was generally a good and effective form of combat when used intelligently.
*'''Basic:'''
**'''Armageddon Battlecruiser:''' An upgraded variant of the Lunar Class Cruiser (YAY! ANOTHER ONE!). A rather new innovation, the Armageddon class is basically made up from recovered Lunar Class Hulks that have been extensively repaired and then retrofitted with more armour and more weapons. The base hull was never designed to cope with all this extra equipment (and the extra crew to man said equipment) and so it has problems operating independently for long periods of time. This isn’t really a problem, though, since they wouldn’t be operating away from a fleet anyway. Though reinforcing its frame to handle the added mass would be a smart thing to do to save immensely in future maintenace costs over the centuries. Battlefleets won't say no to them because more guns = better! These ships are extremely powerful and live up to their name. Somehow, though, the Imperium never went “Hey guys, this thing kicks the shit out of everyone, let’s upgrade all Lunar-class ships to Armageddon-class and make a new class to accomodate the new crew and equipment.” Or someone did and was turned into a servitor...
**'''Hellfire Heavy Cruiser:''' An upgunned Murder-class. Has the same issues as the Armageddon, slow as fuck and has power and supply issues. [[What|Also, lacks Void Shields]]. Most mutinied and joined Chaos, which decided to use them for some reason.
*'''Ordnance-boat:'''
**'''Overlord Battlecruiser:''' The Classic Imperial Battlecruiser. Using the standard Imperial doctrine of - Macrobatteries, Lances and Torpedoes, the Overlord has become the most effective Battlecruiser simply because it really complements standard Imperial Navy Tactics. As an added bonus, its simplicity of design makes it easier to produce and one can be built within a decade. The only negative (if you can call it a negative), is that it's not really useful for anything except war.
**'''Chalice Battlecruiser:''' A fast heavy cruiser. Unique to the Calixis sector and an exceedingly new design, the Chalice was conceived as a Battlecruiser that could either out-run or out-manoeuvre anything it can't kill. Which means it was conceived to be a plain ‘ol normal battlecruiser. Whilst good in theory, unfortunately, speed came at the cost of armour and durability and so whilst these vessels punch hard, they can't take as many hits as other cruisers. In addition, it carries an experimental plasma drive layout, which while boosting power efficiency, also makes it rather vulnerable to lighting up like a roman candle. Imperial Propaganda is currently trying to cover up their failings and is lauding them as the Poster-ships of the Calixis Sector and therefore a lot of people think they're the 'Best Battlecruisers Eva!'. If they would just use a normal plasma drive and make the whole ship bigger, it would be fast enough, armored enough, and even better armed. Unfortunately, not being stupid is heresy in Calixis.
***The idea of a ship that can "either out-run or out-manoeuvre anything it can't kill" that turns out to be really poor at taking hits was the original design of real life Battlecruisers, which although being up-gunned Cruisers (which are the equivalent of Frigates IRL, not Ships of the Line), were used as discount Battleships at Jutland were they turned out to lack the armour required for a proper fight. Thus, if the Imperials were smart, they would be using the Chalice as a commerce raider, not a ship of the line.
**** Actually, they were not bad at taking hits, they were better at it than heavy cruisers. They just sucked at taking hits from battleships like everybody else on the planet. Real life battlecruisers (after their early screw up designs) were made only a little smaller than battleships which allowed them to have greater armor and firepower and speed than heavy cruisers and were even fast enough to outrun battleships at the cost of significantly lower firepower and armor than the only slightly larger battleships (which caused things like the Jutland kablooie). They had the whole package. In reality, the larger the ship the faster it is in navies (broadly speaking, in dense fluids the longer the vehicle is relative to its cross-section, the easier it is to go fast), sci-fi just is made by ignorrants. Battlecruisers fell out of favor shortly after they were perfected for the same reason battleships and heavy cruisers did: the carrier. That said, they were indeed usually used as commerce raiders. But that is true for all ships. Navies exist to destroy enemy commerce shipping and to transport armies. The only reason fleets engage each other is because both sides defend their own shipping and seek out enemy fleets to pre-emptively destroy to protect said shipping and transports. In 40k, it could be said that the Invincible-class is the closest thing the Imperium has to an equivalent to a real life battlecruiser.
**'''Long Serpent Battlecruiser:''' A true success story, this is what the ''Chalice'' wishes it was. Taking a battlecruiser's armour and firepower, and giving it the engine suite of a battleship, this thing can kick the shit out of anything short of a grand cruiser or battleship, while being able to keep up with raiders. It's only real flaw is that when one is taken out, it has a better than average chance of rupturing its warp drive. As a result, the names of ''Long Serpents'' that have been destroyed are usually accompanied by those of allied ships that were too close. Which is somewhat odd since the reasoning is that the Long Serpent also has a battleship's warp core (who knows why, it isn't big enough to need it). Given the small difference in size between this ship and other "normal" cruisers which are the mainstays of the fleet, the Imperium could just choose to use a smaller warp core suitable for this ship's size and focus on mass-producing the Long Serpent to replace basically every other class of ship except battleships , Cobras, and carriers. Fewer would be made but, unlike video games, swarming a capital ship with escorts does not work at all. The escorts are slaughtered and the capital ship like this one is left unharmed. But doing this would require common sense, which is [[Heresy]]. Like properly using the Invincible-class must be.
**'''Mercury Battlecruiser:''' Another fast Battlecruiser. It's a cruiser with a Battleships's engines. Nothing more.
**'''Hades Heavy Cruiser:''' A long-ranged brawler. Carries Broadside Macrobatteries and Dorsal and Prow Lances. Got phased out like most keel-built designs, but Chaos still uses them.
*'''Lance-boats:'''
**'''Acheron Heavy Cruiser:''' Designed to test new Lances and Macrobatteries. The Imperials only built one, which went traitor. Carries Broadside and Dorsal Lances with Prow Macrobatteries.
*'''Carriers:'''
**'''Mars Battlecruiser:''' In a word - Mediocre. Some Imperials say it's versatile due to its diverse weapons loadout but in reality it makes it an awkward duckling to use. The Nova Cannon and Launch bays would be good on a ship holding back and harassing enemies at range and yet it has Macrobatteries and Lances which are great for brawling. So if you sit back and harass or go in and brawl, you're wasting half your ship. The Imperial Navy never really got on with it either and so it has gone out of production on most Forge-Worlds. Which is a shame because if they would replace the macrobatteries and lances with larger, long-range lances, and a great number of small, short range weapons batteries for fighter support and self-defense respectively, this would be a great ship in any fleet. It's nova cannon clears a hole in the enemy escort screen, the attack craft rush through to wreck the weapons and engines of light capital ships while long-range lances assist other Imperial ships in slaughtering targets of opportunity. The destroyed enemy light capital ships leaves all the other big ships vulnerable to mass, concentrated torpedo attack from friendly ships. Attack craft return to the fight to tear up the no-doubt seriously damaged enemy big ships and lances win the day. Then just send in friendly light capital ships with attack craft support to finish off the surviving escorts. That would almost make this ship into a sort of miniature "I Win" button. Almost. Especially in a squadron of two, as they could assist each other against any opponents that slip through to them with their combined, close-range firepower, lances, and whatever attack craft they kept back for defense ripping the enemy weapons and engines apart to let the close-range macrobatteries have fun.
**'''Dominion Battlecruiser:''' Basically a fixed Mars, some tech priest got it in their head that, maybe, it'd make more sense to replace the Macrobatteries with Lance Batteries instead, making it a dedicated support ship, harrassing enemy ships at range whilst the big guns go out and fight. Apparently not that successful, a number were used at the Battle for Maccrage (Of course the fucking Smurfs get them) against the tyranids, though apparently they all got fucked up and have been in drydock since, which is why up until now no-one's seen them.
**'''Styx Heavy Cruiser:''' A pure carrier. Has Broadside Launch Bays, Dorsal Lances and and Prow Macrobatteries. For some reason the Imperial phased it out for the Mars, so only Chaos uses them now.
**'''Hecate Heavy Cruiser:''' An attempt to replace the Styx. Swaps out some of the Launch Bays for Macrobatteries. Believed to have an inherent design flaw that made them go traitor, so they were decommissioned.

===[[Imperial Navy Cruiser|Cruiser]]===
Cruisers are the bread and butter of the Imperial Navy. Much larger than escorts and light cruisers, but less rare than battleships, cruisers are what the Imperial Navy (and Chaos and Xenos) use to fight their campaigns across the stars. Thus far, all Imperial Cruisers have been shown to utilize the same hull-type: a squat armored prow in front, capable of mounting a prow-mounted weapon system, and a big bunch of engines in the back, with baroque and Gothic architecture in-between. Most cruisers can effectively be placed in four categories:
*'''Basic:'''
**'''Lunar:''' The Lunar. You've heard so much about it and now you want to know what it makes it the standard Imperial Cruiser. First of all, it's one of the oldest designs still in use by the Imperium and is so easy to build that even less advanced worlds can produce them. They're quite versatile due to their weapons loadout (a balanced build of Macrobatteries, Lances and Torpedoes) and make up the backbone of Battlefleets throughout the entire Imperium. This is the cruiser against which all other cruisers are measured.
**'''Emasculator:''' Considered a failure by the Imperium at large, Emasculators have the same basic load-out as the Lunar, but are keel-built, lacking the armored prow and replacing the torpedo tubes with more weapons batteries. This means they require different tactics to a Lunar, using their speed and longer ranged weapons to pound ships from a distance. As this fits with Chaos tactics more than Imperials. most of them ended up as traitors. [[/d/|The name Emasculator is due to them being seen mostly as Slaaneshi ships, their original name is unknown.]] The fact the Imperium keeps trying new ships built on the normally Chaos style hulls implies that usually it must work out just fine since otherwise it would have been banned by now. So, there are probably many cool looking keel-based Imperial ship classes floating around we'll never catch wind of ever.
**'''Slaughter:''' A special type of Cruiser, the Slaughter-class has a more powerful drive called the Scartix Engine Coil, but lacks prow weapons. Armed with short ranged, but powerful lances and macrobatteries, the Slaughter is designed to get in close, blast away and retreat. Unfortunately, the Imperium can't build them anymore because one went traitor and destroyed the plans for the Scartix Coil. It is unknown if they were always called the Slaughter-class or were renamed when most went traitor. Considering the usual lack of intelligence in the Imperium's leadership, it was probably called something worse, like the "Traitor-class" or something and then the Imperium wss shocked when they lived up to it. Really, would you be surprised if the Imperium did that?
**'''Inferno:''' A earlier counterpart to the Carnage-class, carrying more lances in exchange for some Macrobatteries. Had the same difficulties as the Carnage and was mothballed, though a few went renegade beforehand. Rare example of the Imperium learning its lesson. Still too stupid to realize that using cheaper-after-a-few-centuries-than-manual-labor auto-loaders would've fixed the problem for both ships.
*'''Lance-boat:'''
**'''Gothic:''' Another variant of the Lunar Class, the Gothic is designed as a heavy Lance gunship. Due to the amount of Lance Weaponry it carries, it can easily deal with ships of its own size or larger but often does require an escort or a partner to strip enemy void shields first in order to use its own weaponry to the maximum effect. When supported and used correctly, Gothic Cruisers are the most efficient way to deal with enemy capital ships.
*'''Ordnance-boat:'''
**'''Dominator:''' A variant of the Lunar Class, the Dominator is designed primarily for planetary bombardment and assault. Not generally used in fleet actions even though it can provide support with its Nova Cannon when necessary. After one Dominator fucked over a Chaos Cruiser with said Nova Cannon during the Gothic War, the Navy took note and started making more Dominators. [[Awesome|Additionally, another Dominator came close to destroying the Terminus Est (''aka the toughest Battleship in the galaxy''), before being destroyed.]] The Dominator possesses the same armament as the Retribution-class battleship but lacks the range of one. This is fine, though, since it's meant to get close to the enemy like most Imperial ships anyway. Basically, if you get in range of this thing, ''you're going to die''.
*** From Lexicanum 40K: "Captain Straden of the Depth of Fury defended the shrine world of Kathur to the death, and came very close to destroying the Death Guard ship Terminus Est. As it was, he and his crew vaporised several of its decks and destroyed scores of escort ships before finally succumbing. Ironically, no Imperial souls survived to tell the tale."
**'''Tyrant:''' The Tyrant was originally intended as a stand-off vessel; it would stay at long range and bombard enemies from afar with superfired plasma weaponry. Unfortunately, due to design compromises where it mixed both short range and long range weaponry to save on power, it wasn't really deadly enough at long range to do its job. Therefore the Imperial Navy is trying to replace the short range weapons with ancient Long-range weaponry (that doesn't use a lot of power) recovered from Space Hulks or Renegade Ships. The Hull itself is a rather effective design and so the Tyrant has become very popular with Rogue Traders who generally replace all of the Plasma Weaponry in order to have more power available compared with other cruisers.
**'''Relentless/Carnage:''' Another attempt at a fleet support ship with Plasma weapons, the Relentless ended up with technical difficulties and, when these were overcome, [[Heresy|most ships ended up turning traitor]] [[Fail|(including the lead ship of the class)]]. [[Tzeentch|This is theorised to be due to something wrong with the geometry of the ship's design]], as the Relentless-class is keel built, like most older ships (This also means the Relentless lacks an armored prow and torpedo tubes, carrying more plasma batteries instead). The tendency of these ships to turn to Chaos, along with changing tactics, led to the class being renamed the Carnage-class and mothballed in favor of the Tyrant-class, though their speed means they suit Chaos tactics famously.
*'''Carrier:'''
**'''Dictator:''' A Carrier retrofit of extremely damaged Lunar Class Cruisers. If a Lunar class has its lance weaponry destroyed, it's quicker, easier and cheaper to replace those with heavy launch bays for strike craft. This makes it quite versatile and able to deal with virtually all situations and interestingly enough, makes it more effective than the original Lunar Class at everything except fighting as a ship of the line. Unfortunately, the Lunar Class is designed for fighting as a ship of the line, so Admirals dislike Dictators.
**'''Jupiter:''' A kitbashed design, converted from other classes of cruiser that have been heavily damaged in battle. By stripping out all the damaged components and replacing them with launch bays, you get a pretty sturdy carrier. Just don't let the enemy get anywhere near it. Apparently the Imperium doesn't build these normally at all, likely because they are absolutely shit at defending themselves from other Cruisers.
**'''Devastation:''' Deviating from the standard Carrier design, the Devastation-class carries Lances instead of Macrobatteries. Mostly turned traitor or mothballed, as they lack armored prows and torpedos; and are keel-built. Chaos likes them, as they can pack them with mutants and sit back to spam assault boats and lances at anything that looks at them funny.
*'''Other:''' Various other cruiser types exist, but are rarer.
**'''Ambition:''' Custom-made Cruisers for the exceedingly affluent - it's the Rolls Royce of the Cruiser World. Most Rogue Trader ships are second-hand, battle-scarred, tired and worn ex-navy vessels but the Ambition is not. It's the only cruiser class that can be bought brand spanking new by Private parties in the Imperium and each one is unique and built to the customer's specifications. These exclusive ships, whilst still cruisers and deadly in their own right, are stately homes and status symbols. Some durability sacrifices have been made in order to make them the most opulent and luxurious ships on the market but for eccentric people like Rogue Traders, it's generally worth it.
**'''Conquest-Class Star Galleon:''' Built for the very first Rogue Traders on the orders of the Emperor himself, the Star Galleon is an ancient and noble design. Whilst not considered heavily armed by modern standards, they're still formidable opponents and yet as specialist exploration vessels they are able to operate independently for many years and can transport greater quantities than other Cruisers. In effect, it's a cruiser fused with a transport and looks fucking amazing.
**'''Murder:''' The predecessor to the Lunar. Differs by being keel-built, exchanging their torpedos for Lances and having more powerful macrobatteries. The majority that appear in modern 40k are Chaos-aligned, as the Imperials mothballed theirs in favor of the Lunar. A few carried lances as well as Macrobatteries, meaning they don't fit into any category. As with the Slaughter, it is unknown if Murder-class is their original name or they were renamed.

===[[Imperial Navy Light Cruiser|Light Cruiser]]===
Smaller than true cruisers, light cruisers are used in two ways. Either you use a fast, maneuverable light cruiser like the Dauntless to add some extra firepower to a scouting squadron or long-range patrol, or you use a pocket cruiser like the Voss light cruisers to add some heavy firepower and armor to a convoy, fleet, or base. The advantage of the light cruisers are that they're cheaper to build and operate than real cruisers. Another departure from real nomenclature. In real life, “light” cruisers were less armed and armored normal cruisers made to make up for losses, especially in America after Japan’s initial attack. After the industry fully turned to wartime manufacturing, the light cruisers’ changes were recinded and they were just normal cruisers again. However, with the introduction of heavy cruisers, the normal cruisers again were named “light” cruisers to avoid confusion. In 40k, however, light cruisers are very distinct and fill a unique niche. Like the Cruiser, they fit into a few base categories.
*'''Basic:''' Same as its larger sibling, a Jack of All Trades.
**'''Dauntless;''' The standard Light Cruiser of the Imperium; it's a Jack-of-all-Trades. You can't go wrong with the Dauntless even though other Light Cruisers may be better for certain tasks. Considered 'scouting' cruisers, these make up the bulk of Imperial Patrol Squadron leaders.
**'''Defender:''' A convoy escort variant of the Dauntless, with added dorsal weaponry.
**'''Endeavour;''' A 'heavy', Light Cruiser, designed as a stop-gap between the 'lighter' light cruisers and true cruisers. Whilst they can slug it out in a fleet fight, they can easily be overwhelmed because they simply aren't cruisers and don't have the equivalent fire-power or hull integrity. As an added titbit, most of Battlefleet Koronus' patrols consist of an Endeavour and a pair of frigates.
**'''Lathe-class Monitor-Cruiser;''' An Adeptus Mechanicus Light Cruiser designed around deep space exploration and extreme self-reliance. These ships, when properly outfitted, can operate for decades without returning to imperial space for resupply. These would make up the bulk of Explorator fleets.
**'''Secutor-class Monitor-Cruiser;''' An Adeptus Mechanicus Light Cruiser designed to excel at the art of war. Tougher than all of the other Light Cruisers and yet still more mobile than true Cruisers. Due to being designed from the ground up to be a Warship, this Light Cruiser is fitted with Cruiser sized Void Shield Generators.
**'''Siluria;''' Three-quarters the cost of the Endeavor, and about three-quarters the ship. Standard weapon batteries only, no fancy frills to speak of. Cheap and effective, at short range, to catch enemy torpedoes.
*'''Lance-boat:''' Also the same as the Cruiser version, though some have weak weapons batteries for better defence.
**'''Endurance;''' Light Cruiser with just enough guns to claim it has them, lance batteries and a couple of torpedoes. It's the lance half of a Lunar, nothing more.
*'''Carrier:''' More useful as a Light Cruiser, as it can act as backup for patrols.
**'''Enforcer:''' A carrier variant of the Dauntless. Designed to maintain control of rebellious planets via intimidation [[Grimdark|(and possible orbital bombardment)]]. Given one managed to stop the rebellion of an ''entire sub-sector'', its a shame the Imperium doesn't build more of them.
**'''Defiant;''' A carrier variant of the Endeavour. It's quite versatile (by virtue of being a carrier) and so has found a home in many Rogue Trader houses but unfortunately the Imperial Navy doesn't consider it as useful because they can't stand by themselves and require an escort. Due to being based off of the Endeavour, it's relatively well armoured for a Light Cruiser and that does help with its survivability.

===Ironclad===
8 kilometer long battering rams. No, really. Tyranids and Orks are busy taking notes.

===[[Imperial Navy Escort|Escort ships]]===
Escorts are the smallest armed vessels available to the Imperial Navy. These ships are normally assigned sector patrol duties or perform as escorts for much larger ships. In fleet engagements they will also act as scouts, ranging out in front of their armada to verify enemy ship numbers and locations. They are generally clasiffied as either frigates, or as destroyer ships.

====Frigates====
Ranging from about 1.4-2km long. They are used for all sorts of duties from convoy escorts to attack or patrol squadrons. Ironically named, as in real life Frigates were the same as Cruisers (which were not Ships of the Line).
*'''Basic:''' Laser batteries only, maybe some Torpedoes if you're lucky. Named after types of swords.
**'''Sword Frigate:''' The most common warship in the Imperial Navy, and one of the simplest. No torpedoes or lances to distract you here; a Sword puts two massive laser batteries behind a pointed armored prow and cuts into enemy formations like [[C.S Goto|a multi-laser through canon.]]
**'''Falchion Frigate:''' A new (245 years old) class of escort ship built by [[Forgeworld|Voss Prime]]. Slow as balls but still capable of firing torpedoes. While Cobras are used offensively in fleet actions, Falchion's are designed to be convoy escorts and stick close to larger warships to defend them from enemy escorts. Effectively a Voss-pattern Sword with torpedo tubes and one laser battery.
**'''Claymore Corvette:''' Designed entirely around escorting vulnerable transports and protecting them against light raiders in order to allow true Frigates to accompany more valuable ships such as Battleships, Battlecruisers and Cruisers. The Claymore Corvettes are easy to mass produce and maintain and are exceedingly common in the private sector, as they are simply a discount Sword.
**'''Turbulent Heavy Frigate:''' Heavy Naval Escorts; these things have comparable armour to cruisers. They're built to sally forth ahead of the main fleet and win skirmishes against enemy scouting forces and vanguard elements. They've garnered a reputation for being lucky; they've contributed to many glorious victories and survived catastrophes that other ship classes have not. Their only downside is that they have rather antiquated communication equipment, probably equipped for durability, not ease of use.
*'''Lance-boat:''' Rarer for Frigates, as they need a Prow slot to mount a Lance.
**'''Firestorm Frigate:''' A Sword-class frigate with a prow-mounted Lance replacing one laser battery. Gives the Sword some extra anti-ship punch that it dearly needs. It's also two hundred meters longer than the Sword-class as a result. The Navy does not like the Marines having them, for some reason.
**'''Thunderbolt Heavy Frigate:''' Not much information on this one, but implied to be a Lance version of the Turbulent, like how the Firestorm is the Lance version of the Sword.
**<s>[[Derp|Given the general naming scheme for Frigate classes is naming them after weapons (Claymore, Sword, Falchion, Gladius etc), the Firestorm would make more sense being called the ''Lance''-class due to its role.]]</s> It's pretty clear refits do not follow the same naming conventions.
*'''Ordnance-boat:''' Mostly upgunned Frigates. Can carry a mix of macrobatteries and small lances.
**'''Tempest Strike Frigate:''' Specialized Brawling frigate designed for devastating enemies at close range. Basically a Sword with a triple armoured prow and heavy short-range broadside batteries. They're often equipped with Assault Boats and Barracks for boarding actions.
**'''Havoc Merchant Raider:''' Small, yet fast raider sized vessels whose impressive firepower came at the expense of armor. Glass Cannons, in large squadrons these can easily overwhelm larger vessels by weight of fire.

====Destroyers====
The most common warship class. Their tasks range from scouting to shuttling VIPs or fighting in fleet engagements in large squadrons. Most pirates use these speedy, nimble vessels to prey upon transport ships.
*'''Basic:''' Usually mounts Prow Torpedoes and a Macrobattery.
**'''Cobra Destroyer:''' The PT-Boats of the Imperial Navy. Small, fast, and lightly armed, their one purpose in life is to fire shoals of torpedoes from 3-8 ship squadrons. A great part of the Imperium's military advantage (in fluff and [[Battlefleet Gothic|on the tabletop]]) comes from all the torpedoes they can fire at the enemy, and the Cobras are a big part of that.
**'''Infidel Raider:''' Was meant to replace the Cobra, but the plans [[Blood Ravens|were stolen]] by Chaos. Armed with Prow Torpedos and a Macrobattery like its predecessor, though some Chaos fleets upgrade them to Heavy Raiders by adding another Macrobattery.
**'''Iconoclast Destroyer:''' If there ever was an Guardsman of starships, the Iconoclast is it. A destroyer so shitty the Navy doesn't want it, the Iconoclast mounts 1-2 macrobatteries and is used by Rogue Traders, Chaos and Pirates. Notable for being one of the few ships to have a forward placed bridge, likely due to the smoke-stack like pylons along its spine.
*'''Torpedo-boat:''' Why waste space on pop guns?
**'''Viper Destroyer:''' Given GW's naming conventions, it was inevitable somebody would do this. Not to be confused with the Sloop below, this is a variant of the Cobra where the guns are replaced by torpedoes. Weak against escorts but deadly in numbers against capital ships. Use [[Boarding Torpedo|Boarding Torpedoes]] for hilarious results.
*'''Lance-boat:''' Rather rare among Raiders, as most use their Prow slots for Torpedoes.
**'''Apostate Heavy Raider:''' A variant of the Infidel. Somehow those heretics managed to shove a full sized Lance into a Dorsal slot, which only Light Cruiser and bigger can normally manage.
**'''Idolator Raider:''' Also known as the "WTF is this" ship, the Idolator is the lovechild of a Infidel, a Firestorm and Xenotech. Has a prow lance and a macrobattery.
*'''Other:''' Mostly weak scouts.
**'''Viper Scout Sloop:''' Smallest warp-capable ship in mass production. It is an exceedingly fast scout ship with ridiculously powerful realspace engines and high-tech auspex scanners. In support of Naval Operations these vessels would burn into enemy territory at high speed, collect as much information as possible and then warp back to friendly territory. Unfortunately they are so specialized that they can't do much else apart from that.
**'''Rudense "Class":''' A small ship designed post Gathering Storm to be as fast, heavily armed, and densely armoured as possible, which they do with aplomb. You may ask yourselves, why are they not used in more regular combat roles? Well, the answer is that they are a specialised orbital insertion ship - designed to get as close to the atmosphere of a heavily defended planet as possible, drop it's cargo of primaris marines into the top layer, and get out of there. Whilst this may seem too specialised to be practical, few enemies are ready for half a company of marines dropping in to their base unexpectedly. (Nb - the class hasn't been formally named yet but the only example of it thus far was named the Rudense).

===Aircraft===
As part of the reforms falling the Horus Heresy the Imperial army was not just split into regiments to insure that no one imperial army could be self sufficient if it fell to heresy or rebellion, the army was also split from it's air power which was given to the Imperial navy. Strictly speaking all atmospheric aircraft are also part of the Imperial Navy, with only [[Phantine Air Corps| few general exceptions]].
*'''[[Fighter]]:''' The fighter's main role is to stop enemy torpedoes and bombers before they can [[anal circumference|rip your flying cathedral multiple new assholes]]. Comes in different models like the [[Fury Interceptor]] or the Thunderbolt Fighter. The main difference is that some can enter a planet's atmosphere to dogfight and/or strafe ground targets where others are limited to space combat.
*'''Bomber:''' Basically reusable torpedoes. Come in different models like the [[Marauder Bomber]] and the [[Starhawk Bomber]], but again the main difference is that some can dip in a planet's atmosphere and drop bombs on ground-pounders where others are space-combat only.

===Armed Freighter (in the Battlefleet)===
Ships bought, borrowed or stolen and then armed in the misguided attempt to boost the strength of a fleet in desperate need of ships (instead of simply using the legio cybernetica to make robots to do the monotonous manual labor so 90% of the hundred thousand crew members can be spread out amongst a hundred more warships)

===Fire Ship===
A fancy name for a fuckheug bomb. A old, damaged or for whatever reason no longer usable ship is packed to the brim with explosives and flown straight into the heart of the enemy formation. Again, Orks are busy taking notes for their Roks. Contrary to what you might think from the Imperium, this is not a suicide assignment. A skeleton crew is used and supplied with plenty of escape pods/lifeboats. The crew evacuates and the ship detonates after they are far out of the danger zone. Some captains decide to go down with the fire ship anyway. Or they mindfuck some penitents to stay and guide it to the best point of detonation. The Imperium isn't short on criminals and/or desperate underclassmen/mutants.

===Non-Warp Capable Vessels===
Vessels incapable of interstellar travel. All but the most primitive Imperial planets have them.
*'''System Ships:''' Civilian ships that do all the civilian stuff like ferrying, mining and transport. As nobody would buy models of them, [[GW]] never bothered to flesh out their canon. If armed, they are dragooned into the System Defense Force during invasions.
*'''Defense Monitor:''' Essentially, a mobile gun emplacement in space. Slow and small, it diverts all its power into the battleship-sized gun it carries. Crewed by regular Imperial Navy personnel and used to augment existing defenses.
*'''System Defense Vessel:''' The primary unit of a System Defense Force aka the [[Planetary Defense Force|PDF]] in space. Nobody knows what they look like or even what capabilities they have. It is assumed they are lightly armed vessels usually used in police actions and customs enforcement. In times of invasion, they use hit and run tactics as best they can until they die.

===Logistic Vessels===
Ships used for the transportation of cargo or individuals. The majority of Imperial ships would fall into this category.

*'''Carrack-Class Transport Ship;''' A newer version of the Conquest Star Galleon. It's a hardy vessel that can defend itself quite well against raiders. The profile even looks like a Military Vessel so opponents who can't distinguish between Imperial Ships could be scared off.

*'''Goliath-Class Factory Ship;''' An Adeptus Mechanicus vessel designed to harvest plasma from Stars. These ships supply the fuel for the entirety of the Imperium. Other ships can be fitted with Plasma Scoops to top up their own tanks but this is the true fuel-harvesting-workhorse of the Imperium.

*'''Jericho-Class Pilgrim Vessel:''' Refinery ships that have been converted into personnel carriers, the majority of which will be transporting poor-er passengers. Can't really defend itself but usually not even worth the bother for pirates.

*'''Loki-Class Q Ship;''' Converted Cargo ships designed to sacrifice some space for added weaponry. They can serve as Convoy defence in a pinch and can surprise the odd pirate who may underestimate them.

*'''Orion-Class Star Clipper;''' Blockade runners through and through. They're designed to transport low-volume but high-quality goods, even through hostile space. Speed is the name of their game. Hell, these things can put some Eldar ships to shame.

*'''Universe-Class Mass Conveyor;''' Think Super-Tanker in space. It's the largest standardized Cargo hauler in the Imperium and is 12km long. It looks freaking awesome too.

*'''Vagabond-Class Merchant Trader;''' Rather small cargo vessel but extremely common. As if to assist with its 'commoner' theme, it makes you yawn just looking at it.

==Adeptus Mechanicus ships==
Being in charge of manufacturing the warships for the other departments of the Imperium, obviously the Adeptus Mechanicus would also have fleets of its own. The official Mechanicum body that constructs and operates spacecraft is known as the Basilikon Astra. Because the Quest for Knowledge can involve long & dangerous travels into unexplored space, it is important that they be heavily armed and armored, so the Adeptus Mechanicus ships generally are overall of higher quality than standard ships, with better tecnology, weapons, and shields. Though the total number of ships the Adeptus Mechanicus has at its disposal dispersed among its many forge worlds is far outnumbered by that of the Imperial Navy, it goes without saying that those responsible for all starship construction reserve for themselves among the most powerful and best-equipped warships encountered anywhere in the Imperium.

*'''[[Ark_Mechanicus|Ark Mechanicus:]]''' If battleships are literal void-traveling cities, then Ark Mechanicus are void-traveling factories or massive laboratories, with industrial capabilities rivaling that of many hive cities, with kilometre upon kilometre of manufactoria, refineries, crackling Plasma Reactors and laboratories, test ranges, chemical vats and gene-bays. This kind of battleships are incredibly large, nigh-mythical ships that are said to endlessly search the stars as part of the Adeptus Mechanicus Quest for Knowledge, being led by a Venerated Archmagos Explorator. An Ark Mechanicus is outfitted with the most powerful weapons available to the Imperium, generally having a balanced set of macro-cannons, lances, launch bays & a Nova Cannon; Because the search of STC into the unknown can be THAT dangerous.

*'''Adeptus Mechanicus Cruiser:''' Besides vanilla cruisers, the Mechanicus have its own original Cruisers & Light Cruisers, that have better equipment than Imperial Navy cruisers, many times they tend to have nova cannons and that they use servitor slaves instead of human slaves, and occasionally use auto-loaders. In resume, take Imperial Cruiser but quit the typical imperial armored prow, make it shinier, give it better weapons, and can put a nova cannon as a plus.

==Important Details==

===Crews===
''Navy crews are made up of officers, techpriests, slave drivers, and slaves.''

A bit of an over-simplification, but broadly true. Due to the Imperium's aversion to AI and Automation each ship needs at least thousands of people to man it. Whenever the crew count gets low, the Imperial Navy sets up fake strip clubs on a planet claiming "Free Hookers" to lure in unsuspecting men (and the occasional woman). Once a future crewman steps in, he's knocked out, bound, gagged, and taken to the ship, [[grimdark|where they'll slave away the rest of their soon-to-be-short existence]] doing everything needed to make flying through space and fighting in the void possible.

This includes dragging shells the size of houses into cannons while being whipped. Still, at least for the crew sex is allowed, in fact encouraged, if for no other reason than maintaining the crew complement. Seriously, whole fucking cities and civilizations arise from the more massive ships, every bit as intricate as a long lived Hive City. [https://www.youtube.com/watch?v=ax7wcShvrus Here is an idea of how it works, right up to the Roman armor, whips and beatings.] Oh and apparently besides whole civilizations, there are whole civilizations of mutants around too. They can more or less settle new worlds for da [[Emprah]] by simply disgorging their excess population, which the crew is probably all too happy to do.

One area where fluff [[Black Library|hasn't been consistent]] is in the uniform worn by Imperial Navy crewmen. Some sources suggest that uniforms are divided by segmentum of the Imperium, while others suggest that it is a sector-by-sector fashion choice. Given the scale the of the Imperium and the fact that Navy fleets are already identified by hull color, it's probably on a segmentum basis, but [[Games Workshop]] doesn't care enough to make a decision about it. For the ranks of the aforementioned shell draggers at the bottom of the naval hierarchy they'd wear a motley collection of their old civilian clothes and whatever they could scrounge up and sew together.

===Travel===
The ships of the [[Imperium]] travel through the [[Warp]] using what's called a warp drive to get to where they're going. However, this isn't your happy, fancy tunnel-of-light like in Star Wars, or everything-moves-fast Star Trek, it is an alternate dimension full of [[Chaos]]. In order to avoid being turned inside-out (think Event Horizon) and getting hentai-raped by every daemon in the warp, the ships rely on what is called the [[Gellar Field]] to keep the [[furries]], undesirables, and various other evil beings out of their ship when traveling through. The Baroque decorations are also implied in helping to ward off said daemons. They rely on a [[Navigator]] that uses the [[Empra]] as a beacon to safely navigate the Warp, hence the title "Navigator".

==Ranks in the Navy==
While the Imperial Navy uses a lot of the ranks in similar fashion to modern militaries, they invariably hold to a more archaic form and are not equivalent to modern day ranking systems. Particularly since it's quite clear that commissions in 40k can often be purchased rather than earned, and that a "Warrant" would most likely hold to the original term and be an "officer by appointment" rather than an enlisted grade. Though considering the immense variety of units within the Imperium, this may not necessarily be the case galaxy-wide, so all options are equally valid. Also, the ship commander will generally be referred to as Captain internally for the sake of simplicity, except in Astartes fleets where they are called shipmasters to avoid confusion regarding the actual rank of Captain in the Astartes.

===Officer Ranks===
*'''Lord-High Admiral of the Imperial Navy''' - This guy is a [[High Lords of Terra|High Lord]] and is the single dude responsible for the '''ENTIRE''' Imperial Navy, though likely he doesn't do much other than delegate to his subordinates and attend tedious High Lord meetings.
*'''Lord-High Admiral''' - There are five of these guys, one for each Segmentum. While they're probably never anywhere near the front lines they probably have more to do, since its their job to oversee the deployment of fleets and materials from sector to sector.
*'''Lord Admiral''' - The guy in charge of a sector fleet who gets direct command of vessels and formations. You see these guys in the fluff quite regularly when "key" worlds ''(like Armageddon)'' need defended or attacked.
*'''Solar Admiral''' - Often a ''terminal'' rank... no really. Occasionally regular Admirals who do good jobs can put themselves forward for promotion to this position, which needs to be approved by the Lord-High Admiral of their Segmentum, then the officer needs to travel to Terra be reviewed by the Lord-High Admiral of the Imperial Navy. Obviously this can take a very, ''VERY'' long time to approve. So they might often be [[Grimdark|dead before the paperwork gets rubber-stamped]]. If they do get approved they are likely to get promoted straight up to sector commander (see Lord Admiral) as a position will probably have opened up while he was waiting. More rarely, Solar Admirals can get sent on "detached duties" which is basically a license to do as they please with their independent fleets.
*'''High Admiral''' - Commands several group of naval fleets (e.g. Battlegroups), often the most senior Navy officer in a Crusade but the things these fucks usually do is just having snacks with their Imperial Guard counterparts and leaving the combat duties to their subordinate Admirals
*'''Admiral''' - Gets put in charge of a fleet and told to oversee some subsectors. He's usually the highest of the "front line" ranks and much of his time will be on active duty patrolling his assigned region.
*'''Vice Admiral''' - Fleets traditionally get split into three parts, with the highest Admiral taking up the portion containing the larger ships, while the "Vice" Admiral takes the "Vanguard" portion of faster moving ships.
*'''Rear Admiral''' - the third portion of a fleet would be the "Rearguard" and usually gets assigned to the youngest/least experienced Admiral in the fleet. His job is usually the quietest one as he gets the mop-up and repair duties.
*'''Commodore''' - an experienced Captain in command of a squadron of capital ships. It's traditionally only a temporary rank, as capital ships don't always get assigned to each other the same way that escorts do. But the realities of war often mean that ships stay together for extended periods, often well beyond the lifespans of generations of captains.
*'''Lord Captain''' - not actually a rank, but an honourific applied to Captains of detached vessels operating independently. The '''"Lord-"''' part implies that they operate with the full authority of the the Imperial Navy when they act so they can deal with outside organisations (like planetary governors, Space Marines or Imperial Guard) on relatively even footing. Sometimes also known by the more archaic term of "Flag-Captain", since as the commander of a detached vessel they figuratively carry their own flag.
*'''Captain''' The commander of a single capital ship or the lead starship in an escort squadron.
*'''Commander''' - Usually the commander of an escort vessel. Is also the ranking officer on board orbital space stations. It also gets used as the terminal rank amongst Pilots, since small attack craft all fall under the remit of the Navy; so a '''Wing Commander''' would get command over all pilots based on a single carrier.
*'''Lord Lieutenant''' - The second-in-command to captains of capital ships, bizarrely Commanders don't hold that role and hold their own positions. Thankfully because a chain of command exists in any military, despite a Wing Commander holding higher "actual" rank over a Lieutenant on a carrier vessel he would not hold any higher authority on that ship than his duties allow for.
*'''Lieutenant''' - a "working" rank. Either holds command over small system vessels or acts as second in command to Commanders of escorts, or as department heads on Capital ships. They are also Squadron leaders amongst pilots.
*'''Sub-Lieutenant / Ensign''' - Team leaders or attack craft pilots
*'''Midshipman''' - Apprentice officers who haven't passed any exams or earned any responsibility, they would exist below the Warrant Officers in terms of authority, despite holding a commission. Midshipmen are commissioned from Imperial Nobility as part of the [[Administratum|Imperial Tithe]] ''(which can mean virtually anyone gets the job if they send their useless heirs just to keep the best ones at home)'' but they are also assigned from the [[Schola Progenium]]. In addition, Midshipmen also may be taken on as a personal favour from the Captain of a vessel if he knows the family. This echoes the ancient real-world practice of young noblemen showing up while the vessel was in dock with a letter from their family and being granted a commission on the Captain's say-so.

===NCO Ranks===
*'''Ship Master''' - the most senior Warrant officer on board a starship, also quite possibly the busiest man on the starship. It's his job to maintain the logs, update stellar navigation charts, oversee ships stores and order supplies, and command a hangar deck if there is one. Basically he's the guy who knows the ship better than anyone. In real-world historical usage, this guy would have an authority equivalent to a Lieutenant on board a starship, and would "mess" ''(ie: occupy the same space)'' as the other officers do.
*'''Bosun''' - ''(Shorthand for Boatswain)'' The NCO directly responsible for all of the common crew members, including [[Commissar|maintaining discipline]]. Despite his position, his actual rank may vary depending upon the size of vessel or operational requirements, in practice it never really matters since he's unlikely to ever meet another Boatswain. ''(real-world Boatswains are typically petty officers or warrant officers, but could be of any rank. They held responsibility over all areas of the ship other than Engineering, which was left to the Chief Engineer, as if the bosun disciplined/executed/imprisoned a skilled crewman from that department the ship could be crippled because of it)''.
**Note that most Capital Ships, but not all Escort ships, may have an actual Naval [[Commissar]] on board in this role, tasked with maintaining discipline up to and [[Blam|including]] the Officer compliment.
*'''Chief Warrant Officer''' - Also called "Chief Petty Officer" on some vessels. Will often be given command of important ship sections ''(like Chief Engineers, helmsmen, or auspex control, as these are are critical to ongoing operation of a starship)''
*'''Warrant Officer''' - You'll find lots of guys of equivalent rank on a ship, in command of various operational sections keeping the ship running at all times:
**Masters of Ordnance - make certain that Torpedoes and Attack craft (if any) are fueled and maintained.
**Master Gunner - have responsibility over all of the weapons batteries through the Gun Captains and make ensure they are loaded and fired when required.
**Master-at-Arms - responsible for all "small" arms on board a starship, overseeing all Sergeants-at-Arms, as well as maintaining order over any barracked Guard regiments currently in transit.
**Master of the Vox - making sense out of the bazillions of messages that run through the bridge at any given moment both internally and externally ''(crews can get pretty massive, and a lot of traffic can come through at once)''.
**Steward - the guy who keeps everyone else well fed.
*'''Gun Captain''' - Funnily enough, the man in charge of a single gun crew. Makes sure that the weapon is taken care of, is reloaded quickly enough, and is accurate when asked to fire. All of that comes back to this guy.
*'''Sergeant-at-Arms''' - Man in charge of the weapons lockers and leader of boarding parties, as well as maintaining ship-board security. Usually they are transferred from [[Imperial Guard]] regiments so that they don't have any prior association with the crew.
*'''Armsmen''' - Crewmen trusted to carry weapons more than a standard issue Lasgun/Laspistol. They are not true soldiers as offensive boarding actions tend to be rare. So these guys still have their own regular responsibilities on board ship. Since they are trusted more, they have slightly more freedom to move around the vessel as well, though most Imperial employees really don't want the job, since it means they get scrutinised more, or they could end up beating up their buddies.
*'''Voidsmen''' - the lowest rank of crewman on board a Naval Starship above the [[Servitor]]s unless the Captain is cool with slavery. If they have a skill or a trade they may be referred to as '''Able Voidsmen''' which is an official rank that might require examinations. Additionally, if they show leadership qualities they might be promoted to '''Leading Voidsman''' and put in charge of work gangs and be considered for promotion to Warrant Officer if a position opens up.

==Notable Problems==
These are problems some have with the Imperial Navy and their fluff....

===General Logistical Problems===
The big problem that the Imperial Navy has is that it's the only organised navy in the galaxy that's trying to defend its massive amounts of space. To do this takes vast numbers of ships but rather thinly spread out. Given the problems of warp travel it's also extremely hard to reinforce friendly fleets under attack. The foes of the navy come essentially in two flavours; raiders who might just manage to scrape together a few converted transports (building even escort-sized ships is a huge undertaking, akin to building damn near the entire American Navy combined from iron ore and making it fly) which take an escort squadron to murder, and huge organized invasion fleets that take a whole fleet to fight. These combine together to mean that outside of fleet bases and important strategic worlds there is nowhere in the Imperium that is actually well-defended. At best a fleet has to be formed and sent out and they could arrive months later. Travel takes a lot of time, and out in the void it can be extremely hard to know what you are actually fighting against, especially since the enemy tend to kill anyone who tries to look at them. So when there's a large enemy force that you absolutely must fight (not fighting is much preferable) you don't just band together whoever was within shouting distance of the flagship and go murdering, you pull together every single vessel in the sector and hope to the Emperor it's enough to do the job.

TL,DR: Acquiring a force sucks when command thinks paperwork and red tape are forms of worship and maintenance thinks the toilet needs a prayer before it is unclogged.

Warships genuinely are vast things and obscenely expensive and risking them at all in major actions is not something anyone does lightly. Each cruiser is larger and more complex than a fully-kitted titan legion. These things are MASSIVE. In the BFG book there's a fluff story of a cruiser being built at a shipyard that orbits a primitive world. The entire population of the planet were given over to mining the resources needed to build one single cruiser. It took them eleven years to mine the ore. Sure, that's a primitive world, but if you think about it that makes carving out the rocks for it the largest single project ever engaged upon without mechanization. If you add together all seven wonders of the world you aren't even close to the pile of rock we're talking about. So these things are a big fucking investment and the high lords really don't like risking them without a really good reason (<s>makes you questioning why they wouldn't build 20 smaller ships instead</s> ship sizes don’t work that way; 20 smaller ships against something capable of killing fifty ships that size is stupid so you build the one large ship so it lasts long enough to be a real threat, that said sacrificing escort and cruiser construction to a slightly smaller number to produce more raiders and destroyers to hunt enemy raiders and target vulnerable enemy populations would be a good idea).

So if you ever wondered why the Navy doesn't get more action, now you know. By the time the big, awesome ships get on the scene the invasion already probably finished and the bad guys moved on. Then you nuke the shit out of them from orbit or drop millions of poor bastards into the meat grinder. Far better idea all round. It's the reason that the enemy, even nutters like Chaos, don't fight in the void without reason. On the ground it's just a scrap, and maybe you win or maybe you don't. If you lose in the void then your campaign on the surface is dead. No reinforcements, no support and a massive constant orbital bombardment to kill everyone left (which sometimes doesn't happen, because, you know, <s>plot armour</s> shields, enemy surface-to-space weapons, don’t want to destroy your own territory when you can send mooks to reclaim it, etc.). That tends to mean fleets hover around and not fighting, one ensuring the other can't directly interfere with the surface war. This is actually an excellent and realistic explanation for why there is significant ground warfare in 40k. Also, ground-based defenses, mobile theater-shields, etc. are common. So, attacking a planet worth anything is like attacking a planet-sized Death Star without the super-weapon. Your ground forces taking out shields and anti-space batteries is critical to achieving anything. But, by that point, most of the enemy is dead and the survivors have either moved to the next defended region or got so stuck-in with your dudes that you can't shoot without killing your own army. Unless you worship Khorne, in which case you really couldn't care less who you kill, even yourself.

So, the navies of the galaxy ultimately get pushed down into either raiders, escorts against raiders, raider-hunters, or babysitting and logistical duty for groundpounders. Which of course brings back the question of why the Navy has such a desire to get more interceptors and bombers for ship-to-ship combat when they rarely engage in combat in the first place and the attack craft are insufficient. Could be to weaken the enemy ships' ability to shoot at the surface, but by the point they would have a target it would have (as stated) gone to a new defended location or whatever else, defeating the point of sending attack craft to weaken the enemy ships' offensive power. They won't shoot at each other, and they can't shoot at the surface (or at least can't shoot anything worth shooting at). In exchange for packing in so many attack craft into hangars designed for countless atmospheric air support fighters and bombers, the Imperial Guard has to die in radically greater numbers than they have any need to since they have limited anti-air capabilities and all of their enemies have no problem sending massive swarms of fighters and bombers at them. That is without even getting to engage the enemy on the ground and not counting the countless soldiers killed as the transports are shot to pieces due to their escorts commonly ditching them to go after obvious bait tactics. Against orders, by the way. Not that they’re ever disciplined for it. Attack craft would be useful for hunting raiders and defending convoys and transports. Maybe that is the Navy’s thinking: “If I had more Furies and Starhawks, I could send them to de-fang attackers of the troop transports and keep the ships that would have been escorting them.”

Thus the rumor that the Navy has no balls. But who needs balls when you have a nova cannon sized dick and eighteen dice worth of fire power.

===Ship Size===
No one is quite sure how big the ships really are. One story claims the Retribution-Class is a mere 3 kilometers long, while another says it is 9 kilometers and up to 20 kilometers.

Your best bet is Rogue Trader, although going by those figures, anything bigger than a cruiser has an average density around that of hydrogen... From a helpful poster on [http://www.heresy-online.net/forums/showthread.php?t=63267&page=2 Heresy-Online] we have this:

For the most accurate scale, look towards the Battlefleet Koronus Expansion, as it is more a stat/rule book than a story. That and previous consensi, as well as cross referencing with the Horus Heresy rulebooks by Forge World (which places Battleships at 8-12km) place Cruisers just above 5 kms, and Battleships in the mid 8s. Please note that most ships above the size of 8ish kilometers are either a unique modified/purpose built flagship or a ship of a small class that is not in widespread calculations. For a sense of scale the largest warship in the world is currently the US Navy's Ford Class Aircraft Carrier measuring in at 337 meters long or 0.337km making the USS Ford the size of a cannon. They have guns literally the length of an Aircraft carrier!

Ultimately, direct numbers are likely useless. The lance turrets have been described as the size of cities and given the size of an Imperial or even a modern city...also, there are about 75 ships in a Sector Fleet. A sector is one thousand cubic lightyears and there are about a thousand sectors in the Imperium. Which means logically those ships should be incredibly massive and easily ten or even a hundred times larger than the size numbers given in fluff given the size and industrial might and manpower of the Imperium.

*Transports and other Attack Craft, typically rated for atmospheric operation; also includes ships designed to be boarding torpedoes.
**<1 kilometer. That's the small ones, there are super transports in 40k as well. (A [[thunderhawk]] would go here).
*Escorts are "small" ships, like the Cobra, designed to flank foes and operate in squads.
**1-2 kilometers.
**Heavy Frigates
**Frigates
**Corvettes
**Destroyers
**Freighters
*Light Cruiser, a smaller Cruiser.
**3-5 kilometers.
*Cruiser, the standard fighting vessel; every Imperial fleet has them.
**5-6 Kilometers.
*Battle Cruiser, a beefed up Cruiser; generally more 'modern' than a Grand Cruiser.
**6-7 kilometers.
*Grand Cruiser; pocket-sized Battleship, very old.
**7-8 kilometers.
*Battleship; the biggest of the lot, simply put.
**8-12 kilometers.
**Battleships
**Fleet Carriers

The Horus Heresy novel "Know No Fear" had this to say about ship sizes, taken from [http://archive.foolz.us/tg/thread/22848349/ /tg/] who quoted it from the book and written here is just the lengths and names of the ships, for simplicity and space:

*Macragge’s Honour. Twenty-six kilometers - Flagship
*Spirit of Konor. Seventeen kilometers - Battleship
*Antrodamicus. Twelve kilometers - Grand Cruiser
*Antipathy. Nine kilometers - Cruiser (note that the book said it had "six thousand lives" on board, which would be an absurdly small crew for its size by 40k or even 21st century standards - Cruisers normally have 85-95 thousand crew in 40k, and that's for normal sized ones, not double length ones like this one. But this is a Horus Heresy ship, so perhaps it's automation was much better then a later 40k ship)
*Aegis of Occluda. Seven kilometers - Class unknown
*Gladius. Four kilometers - Escort
*Then there is the Abyss-class created by Lorgar that is said to match the Phalanx in size. He made three of them.

===Weapon Effects===
If the weapons can annihilate a continent, why can't it destroy a mere hive? Because different writers don't talk to each other that's why. Also shields maybe.

Alternate take: Sure these weapons can destroy continents, but generally speaking why would the Imperial Navy want to bombard a probably Imperial Hive? Another thing to consider is that while Imperial warships are capable of *BLAM*-ing a planet, it requires a lot of ships firing either specialized planet-killing ordnance or just bombarding round the clock. One virus bomb/Cyclonic torpedo/lance shot would do comparatively little damage. But it does make you think about how powerful those void shields must be.

Another take: Something to keep in mind is the different size of ships and thus cannon barrels. A Retribution-class battleship is a lot bigger than a Mars-class battlecruiser is a lot bigger than a Turbulent-class heavy frigate, just to name a few. Different ships have different weapons.

Another Alternate take : The heresy novels elaborate a little on little on the practicalities of Orbital bombardment as a battlefield weapon. Whilst it is occasionally used tactically and reserved as a strategic level weapon, it requires utterly pinpoint accuracy (targeting being off by a millimetre in orbit could result in a shot being kilometres off on the ground) which is only possible when orbit is completely uncontested. It's use during land battles is the VERY definition of Danger Close and often a dead giveaway to the enemy, as allied forces have to withdraw kilometres away before ordering a bombardment, letting an enemy force bunker down or get out the way. Ships are also very easy targets for anti-orbital weapons during bombardment and the effect of a starship hulk hitting a planet you're fighting for is not something to be risked.

Alternate alternate take of an alternate take take: Hives are designed to withstand bombardment from orbit while firing back with enough power to make enemy ships stay away. This is the main reason why massive ground engagements happen (and there are theater shields available, too). For example, the Rock of the Dark Angels survive Caliban being essentially turned into its component atoms via mass bombardment. Also, the previuos "Another Alternate take" directly above this one is right. Now combine that take with this one and really the only way to take an enemy position is to get off your ass and do it yourself the manly way.

Alternated take because alternate takes on alternate takes don't take what it takes: most weapons are jackshit useless against a planet with atmosphere and magnetosphere. Nova cannon shots, plasma bursts and lance batteries are distorted by magnetic fields, macrobattery shots burn up in dense atmosphere, just like torpedoes and most void-faring attack craft.
To fire effectively the ships either have to come CLOSER into low orbit (being exposed to oversized cannons and missile launchers that can be seen around every major spaceport and hive city) and risk being burst open like a pinata, or are forced to just shit bombs from high orbit, being absolutely horrible at aiming.

To the immediate above alternate take: No. Energy dispersal by atmosphere and magnetosphere does not work that way. If it did, we wouldn’t be able to have shuttles in real life. And the effects of atmosphere on lasers is meaningless above a small threshold 40k easily breaks many times over. Same for plasma and atmosphere and magnetosphere. The atmosphere and magnetosphere have no influence on orbital bombardment whatsoever. The shots are too powerful for the planetary environment to matter and it is ridiculous in the extreme to think kinetic rounds used by the Imperial Navy would be vulnerable to being destroyed by mere air friction. An atmosphere is not some sort of adaptive shield that destroys stuff more the faster the stuff goes. Air only heats up to a certain point and then either stops heating further or the air is what is destroyed instead as it breaks apart due to its energy imparted by friction. It isn’t difficult for modern science to build heat-resistant materials capable of this. Expensive in the modern day, but that’s about it. The magnetosphere likewise is not a magic shield of perfect defense. It has only minute effects on lasers, plasma, etc. which is why we have lasers, GPS, etc. and the magnetosphere’s effects are easily overwhelmed to the point of being negated. The atmosphere would actually have more of an effect on lasers and plasma, but the high energy is easily enough to overpower and negate such effects. In the worse case scenario, shooting a planet with a frigate’s laser weapons batteries causes the atmosphere below the shots to turn into basically a plasma shotgun. Same for plasma weapons but probably a fusion shotgun. Wait, why doesn’t the Imperium so that? Oh, right, [[Derp|intelligence is heresy.]]

===Lack of Balls===
It is well-known that most Imperial Navy Officers don't have em.

An Imperial Navy fleet is most effective when Inquisitors take it over. [[Exterminatus|See Here]].

===Carrier Hate===

Back in M36, the Imperial Navy fought a lowkey civil war over fleet doctrine in Segmentum Tempestus known as the Gareox Incident. A cabal of chaos worshipers worked their way high enough in the navy to start designing ships that were ready-built to turn traitor, most of which were carriers. The battlefleet eventually figured out something was off and the result was a giant carriers vs battleships fight that went down the way the Battle off Samar would have if the Japs hadn't been scared shitless by three destroyers. The surviving carriers went openly traitor and since then building new carriers has been borderline heresy so far as the navy is concerned. They don’t hate carriers, but many Imperial ships are basically battlestars, making carriers a pointless waste of resources. Attack craft are mostly used to weaken enemy firepower, shoot down torpedoes and enemy fighters and bombers and boarders, and finish off crippled enemy ships. On their own, they’re largely useless for actually defeating enemy ships. The main reason aircraft are so effective against navies in WW2 and modern navies is that they can use momentum for bombs and missiles to strike hard from above in order to penetrate decks. Space has no such option and every attack from any angle is similar to a torpedo plane attack run from the Second World War. Which is why Starhawk Bombers are basically just torpedoes. However, carriers are useful and accepted, just not useful enough to bother building from scratch and so carriers are almost always either repurposed wrecks of other ships or mothballed carriers being deployed where more attack craft are needed. This almost pointlessness also means carriers are looked down on as barely worth calling support ships.

==Music of the Imperial Navy==
Not to be outdone by the Imperial Guard (as well as to compensate for their aforementioned lack of balls), the Imperial Navy has begun collecting music to either be blared on loudspeakers when not in active use, or in the case of battleship command decks, played live by orchestra. the first four are taken from [[Battlefleet Gothic Armada|Battlefleet Gothic Armada.]]

The '''Battle of Calth''' was one of the major battles of the Horus Heresy and the reason for most of the current hatred between the [[Word Bearers]] and Ultramarines.

==Prior to the battle==
After [[God-Emperor of Mankind|Big E.]] chastised and publicly shamed the [[Word Bearers]] by making them kneel in front of him and the [[Ultramarines]], [[Lorgar]] was [[butthurt|slightly miffed]], fell to [[Chaos]], started the [[Horus Heresy]]... You know the drill.

Horus ordered the Ultramarines to muster at Calth, ostensibly for a joint operation with the Word Bearers against [[Orks]]. Because of his distance from the galactic center and the general absence of reliable communications in the Imperium, Guilliman had no idea that the [[Dropsite Massacre]] had happened or had any inkling that anything was wrong at all. From his point of view he suspected nothing and hoped that this action would mend his relation with his brother, so assembled (almost all of) his Legion and waited for Lorgar's troops to arrive.

On Lorgar's part, he and his brother [[Angron]] got together in the aftermath of the Isstvan massacre, collected three-hundred thousand legionaries between them and double-timed it to the Ultramar sector, initiating the '''Shadow Crusade''' on the way and burning a ''"bloody trail across the eastern segmentum"''. The Ultramarines were still ignorant of these early battles thanks to both the speed of the traitor's advance, coupled with the fact that they seldom left any survivors.

When preparing for the muster at Calth, Lorgar split his Legion into multiple groups, keeping the larger part for himself, but deploying 50,000 marines, chosen from the most unstable and the least zealous of his legion to represent him. He also gave them the bulk of his fleet to maintain the ruse that the entire legion had arrived at the muster, when in fact they were already spread throughout the 500 worlds causing generalized mayhem.

While one of Lorgar's desires was to get back at Guilliman, he had been informed through the counsel of Kairos Fateweaver that the upcoming battle would have been his opportunity to kill Guilliman if he desired, although if he did so it would actually hinder the traitors efforts to reach Terra and potentially cause Horus to fail in the long run. We now know with hind-sight that if Guilliman had died then [[Imperium Secundus]] would not have happened and those resources and manpower that he gathered would have been spread elsewhere. Therefore while Lorgar was present at the muster at Calth, he departed to continue the Shadow Crusade as soon as the battle started, leaving overall command to [[Kor Phaeron]].

The entire thing is stupid for a certain reason everyone reading this already thought of: astropaths are a thing.

==Opening==
The Word Bearers were not terribly subtle about their shady intentions, but Guilliman and his Legion were both unprepared for a treacherous attack from a presumed friendly force. The first action Erebus's forces took was to attack a maintenance vessel, the ''Campanile'', and take it over without the Ultramarines noticing. The Word Bearers' forces began a ritual that would implant Chaos-infected scrapcode into the Calth orbital defense network, while they deployed forces to the planet's surface under the cover of beginning coordination with the Ultramarines.

Being the efficient pragmatists that they were, the Ultramarines had a system for post-battle analysis. One of the key components of this was the "Mark" system, where all forces would record a certain time for the official start of the battle, Mark Zero, and record actions based on that initial time point. Twenty minutes prior to Mark Zero of the Battle of Calth, the ''Campanile'', moving at a significant percentage of lightspeed, crashed into the Calth orbital docks. Thousands died in the explosion, and seconds later the Word Bearers fleet opened fire on the Ultramarines. After Guilliman's urgent plea for a ceasefire was ignored and Lorgar openly declared his traitorous intentions, he gave the order to fire back, officially beginning the battle.

==The battle==
As the orbital defense network was helpless and the Ultramarines fleet was fighting for survival, the Word Bearers vessels could bombard Calth with impunity, which they did. After Guilliman put two and two together and realized this was a deliberately planned attack, he angrily phoned up Lorgar, promising to kill him and every one of his sons. Lorgar, laughing his ass off, summoned a swarm of daemons onto the ''Macragge's Honour'' which tossed Guilliman (who wasn't wearing a helmet) and his entire bridge crew into the void.

[[Aeonid Thiel]], an Ultramarines sergeant who had been punished for planning and simulating Astartes vs. Astartes combat situations, led the attack to retake the ''Macragge's Honour'' from the daemonic forces. They managed to do so after about ten hours of vicious fighting. Just eleven hours into the battle, the Ultramarine commanders estimated that over 100,000 legionaries were dead, leaving them severely outnumbered by the Word Bearers. Thiel and co. found Guilliman on the outside of the ''Macragge's Honour'', still not wearing a helmet, killing Word Bearer boarding parties with his bare hands.

While the Ultramarines were still in a bad spot, they were beginning to fight back. [[Kor Phaeron]] proceeded to reactivate some of the orbital defense platforms and began firing into Calth's sun. With fatal radiation bombarding Calth's surface, both sides' forces on the planet retreated underground, engaging in a brutal series of close-quarters battles in the Calth tunnel networks.

Guilliman led an attack on the platforms, where he and Kor Phaeron confronted each other. The latter managed to wound the Ultramarine primarch with the [[anathame]], but Guilliman told him to fuck off with that Chaos nonsense and ripped one of his hearts out. The Word Bearer, being a little bitch, teleported away with his main forces, allowing the Ultramarines to retake the platform and purge the scrapcode. Guilliman ordered the ''Macragge's Honour'' to pursue the Word Bearer's flagship, the ''Infidus Imperator''. The latter was destroyed after a vicious void battle.

==Aftermath==
Though technically an Ultramarines victory due to the fact the attacking Word Bearers were exterminated, Lorgar was happy with the result, seeing it as a sacrifice to the Dark Gods (causing the Ruinstorm), a means of purging his Legion of those whose devotion to Chaos was suspect, and as a way of irrevocably pissing off Guilliman.

And piss him off it did. The Mark of Calth is still running and will continue to run until the Ultras finally hunt down and kill the last Word Bearer.

The good thing that came out of this Battle is that the Ultrasmurfs got their butts handed to them, so if you [[Dark Eldar|sadistically enjoy]] the deaths of [[Grimdark|hundreds of thousands]] of smurfs, then you will love this battle.

Imperial Navy

2019-10-08T18:31:47Z

[[File:imperialnavy1.jpg|400px|thumb||Cathedrals IN SPEHSS!]]

{{Topquote|When you began, you couldn’t have possessed enough bones for the whole ship. It would look stupid with a few dozen skeletons nailed to the walls. So, how do you start? Do you save up enough bodies for a corridor at a time, or put them away until you have enough to decorate the entire vessel?’|Jain Zar,-Storm of Silence}}

{{Topquote|By my faith, may the light of the Emperor spread to the farthest star. By my duty, the galaxy will belong to the righteous. By my actions, the Imperial Navy shall be honoured and remembered on Holy Terra. For the Emperor of Mankind, AND FOR THE BATTLEFLEET GOTHIC!|Imperial Navy Captain Abridal, shorty before his blaze of glory that ultimately stopped the 12th Black Crusade and saved billions of Imperial lives.}}

The '''Imperial Navy''' is one of the main branches of the [[Imperium of Man|Imperial]] military in [[Warhammer 40,000]] (although very little of the Navy actually appears in the tabletop game). They are also one of the main factions in the beloved spin-off game [[Battlefleet Gothic]].

Unlike the [[Imperial Guard]], who get killed in the <s>thousands</s> <s>millions</s> billions every day, the Imperial Navy rarely suffers that many casualties. This is because, unlike the [[lasgun|flashlight]] used by Guardsmen, the main weapon of the Navy is a giant, heavily-armed, heavily-armored battleship that puts other races' spaceships to shame (well, except [[Necrons]]). These ships are also [[Awesome|massive, flying, Gothic cathedrals]].

Depending on how you look at it (and who you're looking at), the officers of the Navy are either wealthy cowards or badass gentlemen. In either case, their ships have crews numbering the hundreds of thousands or even millions (we're not kidding when we say that each ship has its own language(s) and culture(s)), since the Imperial Navy doesn't understand how auto-loaders work, so loading a gun requires thousands of slaves running on treadmills. Of course, this might be the fault of [[Adeptus Mechanicus|a certain other branch of the Imperium, who, coincidentally, ''do'' have working auto-loaders on their ships]]. In any case, [[Grimdark|the Imperium has found it cheaper and ''more effective'' to use manpower because they have ''that many people'' to throw at even the tiniest of problems.]] Except that the cost of hundreds of thousands or even millions of chain-gangs adds up over centuries and millennia whereas maintenance for the machinery would basically amount to "apply oil while chanting". Of course, for a major officer, most days simply require him to press a button and blow something up, then go back to drinking his tea. Oh, and ''maybe'' scramble the ground-support flyers, if he's feeling charitable that day.

Note that, back in the [[Great Crusade]], the Imperial Guard and Imperial Navy were one and the same, operating under the far-less-badass name of "Imperial Army." However, thanks to the [[Horus Heresy]], the two got split up, so that a single military commander couldn't control too many forces; a Guard commander isn't able to get off any given planet without the Navy, and the Navy isn't able to conduct wars (and, you know, occupy territory) without the Guard. You'd think that this enforced mutual co-dependence would make them collaborate, but [[grimdark|of course]], despite how much they need each other, the two bicker constantly, which, in fact, may be the reason for all the [[fail|stupidity]] the 40k universe is saddled with, at least on the military front.

==Types of Ships==
The Imperial Navy has four types of ships they hide their cowardly asses in. The main ships are battleships, cruisers, escorts, and fighters
Each ship can also be classified by its weaponry, and role in the battlefleet:
*'''Basic:''' Jack of All Trades ships, due to having multiples weapons types, and not being specialized into any. Lunar class cruisers are the prime example, having macrobateries, lances & torpedoes.
*'''Lance-boats:''' Ships that focus into Lance weaponry, used for long-range focused attacks, especially against small ships & unshielded ones. Rarer as they have a weakness to Void Shields and require better drives due to the power requirements of the lances.
*'''Ordnance-boat:''' Opposite of the Lance-boat, replaces Lances with more Macrobatteries, focusing mostly into medium & short range brawls against enemy ships. Usually this is because they need extra power due to mounting a Nova Cannon or having power-hungry macrobatteries such as Plasma Cannons.
*'''Carrier:''' The red-haired stepchild of the Navy. Replaces the Lances with Launch Bays and is disliked by most Admirals due to the stigma against Attack Craft, although it is because the Traitors & Chaos pawns focused on raiding & striking fast, so with enemy fleets focused on long range attack (Lances, laser, and attack craft)plus Chaos likes them more because they can fill the bays with Assault Boats, the Imperial Navy might have got that stigma of seeing too many Chaos carriers raiding & pillaging imperial planets & so started dislike them. Some Carriers are also made from wrecked cruisers of other types, in which case damaged broadside weapons are ripped out and replaced by launch bays.
*'''Torpedo-boat:''' Originally an experiment for escort ships to overrun enemy vessel crews using boarding torpedoes, it was doomed to failure as the targets were either too nimble or too big. The Imperial Navy kept a few as Missile Destroyers.

===[[Imperial Navy Battleship|Battleship]]===
Supposedly rare, but every Grand Marshal and High Admiral has at least one and often several or even dozens to hide in because GW is completely and hopelessly inconsistent with fleet sizes, though as of late it seems that GW is leaning towards big fleets and big armies when it gives numbers. Bonus points if that coward is also Chaos. The biggest heaviest hitters available, these things are like actual medieval cathedrals in that the grandchildren of the workers who start building them get to live to see their completion. Fuckheug, lots (and lots, and lots) of guns and most can deploy fighters and bombers.
*'''Ordnance-boats:'''
**'''Retribution:''' Packing all gun batteries, the ship can devastate an entire continent in one broadside, but for some reason cannot destroy a hive city or fort with [[void shields]] - [[What|or in some cases, ones without any shields at all]]; either that or GW was just pulling another [[Derp|Michael Bay]] out of their asses again since, they have no idea how [[Herp|consistency works, let alone basic physics.]] Of course, considering the Dark Angels fortress-monastery and the huge chunk of land surrounding it survived the bombardment which turned Caliban into a bunch of space dust, it is perfectly reasonable that something that merely glasses half a continent would not destroy a void shielded city or other major fortification. If anything, this provides a degree of insight into why land battles in 40k are so massive in the first place. Because orbital artillery doesn't have many targets of opportunity it is actually capable of exploiting without tearing the planet to pieces.
**'''Invincible:''' An interesting class, dubbed a 'fast battleship', these were designed to chase down xenos and chaos raiders, and then use them to make the vast, empty tracts of space more interesting by filling it with their enemies' debris fields. This type of battleship combines the firepower of a ''Retribution'' with the speed of a ''Dauntless''. The problem with this is the general incompetence of Imperial tacticians. It looks exactly like a ''Retribution'' and has the guns to match, so it must be one, right? NO. They excelled at the role they were designed for, but throw them into gunfights against dedicated battleships, and these things tended to come apart easier than wet cardboard, earning them the nickname 'Kisher's Kombustibles' and the scorn of many admirals. Admirals who ignored the fact that the reports detailing the introduction of the ship and how to best use it (it's tactics also included in the Tactica Imperialis) explicitly state not to use it on a gun-line and that it is for fast-ship interdiction. The ship's Commissars must be particularly incompetent to let this slide as in the Guard the generals would be executed quickly for such incompetence. Of course, these are also the Commissars who do nothing when troop transports' escorts frequently run off to fight while the transports lose a significant percentage of their ships. Perhaps if they would actually enforce their orders to stay with the transports, the Imperium would have won most of the campaigns it has lost. Given that they still often win even with a fraction of their beginning ground forces actually managing to make landfall. [[Grimdark|Because they have THAT many men to throw at the enemy.]]
***Much like the Chalice-class of Battlecruisers, the Invincibles are a big reference to the real life Battlecruisers of World War 1, especially with the term "Kisher's Kombustibles" (real life Battlecruisers were referred to as "Fisher's Combustibles") and the fact that three blew up in a single battle (referencing Jutland).
*'''Lance-boat:'''
**'''Apocalypse:''' One of the oldest ship designs (predating the ''Retribution'', which is also one of the oldest ship designs), this ship packs a lot of [[lances]] and a [[Nova Cannon]]. Good for taking out lots of smaller sized ships with massed lance fire. It's also described in fluff as being able to cripple anything up to a cruiser with a single, concentrated broadside. They're fairly rare, since the Imperium doesn't know how to build them anymore, and the ones still operating are so old, their weapons systems have degraded permanently, forcing them to fire their lances at only a fraction of their full power. Shares all the disadvantages of a ''Gothic''-class cruiser.
***Despite the fluff stating that the Apocalypse and Oberon classes are unique in that they lack figure-heads, the artwork and [[Crunch|models]] [[Derp|give them one anyway.]]
**'''Victory:''' Possibly an attempt to recreate the ''Apocalypse'' class, the ''Victory'' is basically a ''Retribution'' with a bunch of lances replacing its broadside cannons, and a Nova Cannon instead of torpedoes. Has the range that fluff states the ''Apocalypses'' once had, but lacks the same level of firepower. Effective at sniping, and hilarious when used against escort heavy fleets.
**'''Desolator:''' A ridiculously old design. Designed to emphasize range and carries Torpedos, Broadside Lances and Dorsal Macrobatteries. Like most keel-built ships, the Desolators ended up mothballed or went traitor.
*'''Carrier:'''
**'''Emperor:''' The "standard" battleship of the 40k 'verse, the ship has multiple fighter decks and weapons batteries. Unfortunately, most commanders like to use this ship as a hideout, causing the lack of sufficient air support in the ground wars even though the Navy's atmospheric aircraft are completely different from its much bigger space based strike craft. Tabletop-wise, its status as the official battleship of Battlefleet Gothic doesn't stop it from losing carrier duels against the Chaos equivalent.
***Ironically, the idea of the Emperor being the standard battleship conflicts with the fluff about the Navy hating Carriers. Go figure. Except it doesnt. Because the Imperial Navy isnt fond of carrier ships, but that doesnt mean they dont use them; So if you were an imperial admiral, would you choose to get multiple smaller carriers, at the cost of having less ship-of-the-line on your fleet? Or would you instead get a 8+ kilometer battleship with four city-sized hangar bays, having higher detection, and being capable of helping your fleet & any warzone in multiple ways (Not just void warfare, but also ground support in planet invasions, or logistical support) without the need of going too close to the enemy? Its no wonder the Emperor Class is so popular & useful in the Imperial Navy, looking at this way, in reality, the Emperor class goes well precisely on the conventional Imperial doctrine because of this reason. Despite the (idiotic) distaste Admirals have for strike craft, they will use still use them out of simple utility and they figure they might as well get something that can do more at the same time.
**'''Nemesis:''' The super-carrier of the Imperial Navy. It has SIX flight decks (the size of towns or small cities, each), more than any other ship in the galaxy. But because of Rule of Cool, it is incredibly rare since the Navy captains prefer to get up close broadside their enemies, or actually rather because all of the ships in this class were just ships modified from Emperor class ships in one particular war, because they were damaged or otherwise. Naturally, the Navy never considers making them based on the Invincible instead (the Invincible was mass-produced).
**'''Desecrator:''' The carrier variant of the Desolator. Replaces half the Broadside Lances with Landing Bays. Shared the same fate as its sister class and is now only seen in Chaos fleets. Traitorous despite its clearly pious and Emperor-loving name.
**'''Despoiler:''' Oh boy, where do we start? The Despoiler-class came about after the cogboys discovered plans for a carrier on Barbarus. The catch? Well, Barbarus is the former homeworld of the [[Death Guard]], and the plans were for the same class of ship that the [[Terminus Est]] is a part of. Showing a complete lack of common sense, the Imperial Navy decided to build ships of this class, only for them all to go traitor due to the class's inherent [[Gellar Field]] flaws. [[Fail|Oops]]. The Despoilers at first don't appear to be that unique, as they have Dorsal Lances and Broadside Landing Bays and Weapons Batteries. Their difference is that, like the Terminus Est, they managed to have a Prow Landing Bay as well.
***Despite being a new class, GW fucked up their fluff and had [[Rogal Dorn]] disappear aboard a Despoiler, [[What|5000 years before the class was created]]. Note this class was actually already named "Despoiler-class" by the Imperium. Yet, they were ''surprised'' the things went traitor. Wow. Also, after fixing the Gellar Field problem, the Imperium still decided not to build more, which was stupid since there was no longer a reason not to. I get not wanting to chance it, but beggars can't be choosers.
*'''Other:'''
**'''[[Gloriana-class_Battleship|Gloriana]]:''' Massive, terrifying and capable of decimating entire fleets on their own, these were the personal flagships of the Primarchs during the Great Crusade. Very few, if any, are still around in the Imperium in M41, though a few such as Horus's flagship ''[[Vengeful Spirit]]'' are still tooling around inside the Eye of Terror. Because they were dickheads, the [[Alpha Legion]] had two, creatively named the ''Alpha'' and the ''Beta''. Interestingly, the Ultramarines have one, the ''[[Macragge's Honour]]'', but didn't [[derp|fucking]] use it, the whole fucking time until [[Roboute Guilliman]] returned. It shows up again in ''Dark Imperium,'' with the Smurfs having stolen it back from the Red Corsairs, which at least is fucking funny even if it makes no sense. The Imperial Fist had the ''Eternal Crusader'', but it was never their flagship since the [[Phalanx]] is so much better, so [[Rogal Dorn]] gave it to the [[Black Templars]] in the [[Second Founding]]. The Emperor is known to have had at least one, called the ''Bucephalus'' (also the name of the horse of Alexander the Great... coincidence?), which he ditched after upgrading to an enormous golden space palace called ''Imperator Somnium'' for the sole purpose of flying him back to Terra to retire. Wait, did Emps just see the Phalanx and decide to build his own bigger better version?! [[Eldrad|DICK]].
**'''Oberon:''' The mixed-breed bastard of the Imperial Navy. It has [[lances]], fighter bays, and weapon batteries. Its a powerful ship... <s>when fighting foes half its size</s> "Newer" fluff says the Oberon is rare, but a complete success in making a ship capable of killing anything it comes across, alone. Unfortunately, fluff also says a ridiculously low number of these (apparently) powerful ships were made (like, 3 or so). Then again: only four Iowa class battleships ships were built (technically 6, but 2 were scrapped before completion), and we know HOW to build them. It makes sense in a way. Attack craft can cripple an enemy's main weapons and engines and likely ultimately damage the power transfer from generators to void shields. Combined with macro-batteries hammering away and the enemy's weakened ability to maintain its shields would cause them to drop much quicker than usual. Then the city-sized lance-batteries rip the enemy in half. If used against enemy escorts to support attacks on large enemy ships like battleships and grandcruisers, this would work extremely well to the point an Oberon would likely become a priority target for enemy ships.

===[[Imperial Navy Grand Cruiser|Grand Cruiser]]===
Only slightly weaker and less powerful than Battleships, Grand Cruisers were the weird middle-child of actual Line Ships (that really were the mainstay of the fleet back then) and Cruisers in the ancient Imperium. Built primarily with autonomy in mind, those were reserved for the most daring expeditions in the uncharted regions, conducted both by Imperial Army and Rogue Traders. Nowadays most of them run on archeotech that is barely understood and hard to repair with current Imperial knowledge. These grand ships are often used as flagships in lieu of extremely rare Battleships. Basically, they are the quintessential Battlecruisers; tougher and deadlier than Cruisers and yet more mobile than Battleships.
*'''Basic'''
**'''Vengeance/Furious:''' The granddaddy of "modern" Imperial warships. The ''Vengeance'' was the winner of a GW-sponsored ship design contest, and was originally known as the ''Furious''. Highlights include heavy shielding and armour (though lacking the prow armour of later designs), as well as both lances and long range weapons batteries, making this the sniper of the Imperium's Grand Cruisers.
**'''Repulsive:''' Originally named the Corinus Class, before being renamed after many fell to Chaos by an overly literal Mechanicum designation. Whilst the Repulsive Grand Cruisers are exceedingly maneuverable heavy warships (and therefore exceedingly useful because they can fill a hole in the Imperial tactical lineup), they are considered a cursed class due to the majority of them falling to chaos, [[Fail|which unfortunately was the result of experimental warp drives which occasionally interfered with the Gellar Field (OMGWTFBBQTIME)]]. Only the Emperor knows what kind of complete moron would deploy ships equipped with that. The ones that remain in Imperial control are kept mothballed in reserve fleets and segmentum fortresses (imagine giant glass boxes with 'In Case of Emergency, Break Glass' signs). It doesn't say anything about their warp drives being swapped out for something that isn't shitty or perhaps a completed and no longer experimental version of their own. Not that you want AdMechs tear off your head for tinkering with their sacred templates, on the other hand.
*'''Ordnance-boat:'''
**'''Avenger:''' The short range brawler of the Imperium's Grand Cruisers, it's a ''Vengeance'' with only macrobatteries (kilometres of Macrobattery broadsides). Intended to break the line of battle like Nelson's ships at Trafalgar, while suffering from the lack of an armored prow. Unfortunately line-breaking is quite a dangerous role for any ship, even a Grand Cruiser that excels at doing it, and so not many exist in the 41st Millennium. Those that have survived are known for being exceedingly reliable and faithful; it takes a lot of damage or mistreatment to cause these noble vessels to give trouble. If you spoke with members of the Imperium (both members of the public and the navy), this is the vessel they would think of if you asked them about Grand Cruisers. Now, if only the Imperium realized a slower but more heavily armored and shielded ship would fare better in its role.
*'''Lance-boat:'''
**'''Executor:''' The sniper of the Vengeances, the Executor replaces its Broadside Macrobatteries with even more Lances. Unfortunately, the last remaining Imperial Executors decided to act retarded and chase a fleet into the Eye of Terror, meaning that all of the ships are chaos aligned now.
*'''Carrier:'''
**'''Exorcist:''' A ''Vengeance'' that has carrier bays in place of lances. Useful in providing carrier support to any Imperial fleet. As a bonus, being Grand Cuisers mean they can outrun anything except battleships to save their vulnerable carrier self while their attack craft are away. Originally designed for extended operations alone on the Frontiers of Imperial Space, either on Patrol or by exploring into the unknown, the Exorcist developed quite a reputation for 'boldly going where no man has gone before'. Whilst not many remain in Imperial Service due to maintenance difficulties, they still find use in the hands of Rogue Traders who need vessels capable of long cruises and of defending themselves against anything they might encounter. So much for maintenance difficulties.
**'''Retaliator:''' A mix of a Repulsive and a Vengeance, but as a Carrier. Has Lances, Launch Bays and Macrobatteries on its Broadsides. Unfortunately, it has the Repulsive's tendency to go traitor.

===[[Imperial Navy Battlecruiser|Battlecruiser]]===
What do you do when you forget how to maintain an entire category of heavy warships? You build a new bunch of heavy warships, with simpler technology.

Battlecruisers are basically upgunned cruisers, with more weapons (usually adding dorsal weapons and some armor), and are intended to fill the gap between true battleships, which are rare, and normal cruisers, which tend to die really easily to the ancient Chaos cruisers and grand cruisers. Battle cruisers were tried in real life as some way to combine battleship firepower or armor and cruiser speed. They did not always work, and much like reality these things have their share of problems. Chaos operates their own versions known as Heavy Cruisers. In real life, the accepted successful form of a battlecruiser is between a heavy cruiser and a battleship; it can kill anything it can catch and it can outrun anything that can kill it (usually only an enemy battleship). After its teething years it was generally a good and effective form of combat when used intelligently.
*'''Basic:'''
**'''Armageddon Battlecruiser:''' An upgraded variant of the Lunar Class Cruiser (YAY! ANOTHER ONE!). A rather new innovation, the Armageddon class is basically made up from recovered Lunar Class Hulks that have been extensively repaired and then retrofitted with more armour and more weapons. The base hull was never designed to cope with all this extra equipment (and the extra crew to man said equipment) and so it has problems operating independently for long periods of time. This isn’t really a problem, though, since they wouldn’t be operating away from a fleet anyway. Though reinforcing its frame to handle the added mass would be a smart thing to do to save immensely in future maintenace costs over the centuries. Battlefleets won't say no to them because more guns = better! These ships are extremely powerful and live up to their name. Somehow, though, the Imperium never went “Hey guys, this thing kicks the shit out of everyone, let’s upgrade all Lunar-class ships to Armageddon-class and make a new class to accomodate the new crew and equipment.” Or someone did and was turned into a servitor...
**'''Hellfire Heavy Cruiser:''' An upgunned Murder-class. Has the same issues as the Armageddon, slow as fuck and has power and supply issues. [[What|Also, lacks Void Shields]]. Most mutinied and joined Chaos, which decided to use them for some reason.
*'''Ordnance-boat:'''
**'''Overlord Battlecruiser:''' The Classic Imperial Battlecruiser. Using the standard Imperial doctrine of - Macrobatteries, Lances and Torpedoes, the Overlord has become the most effective Battlecruiser simply because it really complements standard Imperial Navy Tactics. As an added bonus, its simplicity of design makes it easier to produce and one can be built within a decade. The only negative (if you can call it a negative), is that it's not really useful for anything except war.
**'''Chalice Battlecruiser:''' A fast heavy cruiser. Unique to the Calixis sector and an exceedingly new design, the Chalice was conceived as a Battlecruiser that could either out-run or out-manoeuvre anything it can't kill. Which means it was conceived to be a plain ‘ol normal battlecruiser. Whilst good in theory, unfortunately, speed came at the cost of armour and durability and so whilst these vessels punch hard, they can't take as many hits as other cruisers. In addition, it carries an experimental plasma drive layout, which while boosting power efficiency, also makes it rather vulnerable to lighting up like a roman candle. Imperial Propaganda is currently trying to cover up their failings and is lauding them as the Poster-ships of the Calixis Sector and therefore a lot of people think they're the 'Best Battlecruisers Eva!'. If they would just use a normal plasma drive and make the whole ship bigger, it would be fast enough, armored enough, and even better armed. Unfortunately, not being stupid is heresy in Calixis.
***The idea of a ship that can "either out-run or out-manoeuvre anything it can't kill" that turns out to be really poor at taking hits was the original design of real life Battlecruisers, which although being up-gunned Cruisers (which are the equivalent of Frigates IRL, not Ships of the Line), were used as discount Battleships at Jutland were they turned out to lack the armour required for a proper fight. Thus, if the Imperials were smart, they would be using the Chalice as a commerce raider, not a ship of the line.
**** Actually, they were not bad at taking hits, they were better at it than heavy cruisers. They just sucked at taking hits from battleships like everybody else on the planet. Real life battlecruisers (after their early screw up designs) were made only a little smaller than battleships which allowed them to have greater armor and firepower and speed than heavy cruisers and were even fast enough to outrun battleships at the cost of significantly lower firepower and armor than the only slightly larger battleships (which caused things like the Jutland kablooie). They had the whole package. In reality, the larger the ship the faster it is in navies (broadly speaking, in dense fluids the longer the vehicle is relative to its cross-section, the easier it is to go fast), sci-fi just is made by ignorrants. Battlecruisers fell out of favor shortly after they were perfected for the same reason battleships and heavy cruisers did: the carrier. That said, they were indeed usually used as commerce raiders. But that is true for all ships. Navies exist to destroy enemy commerce shipping and to transport armies. The only reason fleets engage each other is because both sides defend their own shipping and seek out enemy fleets to pre-emptively destroy to protect said shipping and transports. In 40k, it could be said that the Invincible-class is the closest thing the Imperium has to an equivalent to a real life battlecruiser.
**'''Long Serpent Battlecruiser:''' A true success story, this is what the ''Chalice'' wishes it was. Taking a battlecruiser's armour and firepower, and giving it the engine suite of a battleship, this thing can kick the shit out of anything short of a grand cruiser or battleship, while being able to keep up with raiders. It's only real flaw is that when one is taken out, it has a better than average chance of rupturing its warp drive. As a result, the names of ''Long Serpents'' that have been destroyed are usually accompanied by those of allied ships that were too close. Which is somewhat odd since the reasoning is that the Long Serpent also has a battleship's warp core (who knows why, it isn't big enough to need it). Given the small difference in size between this ship and other "normal" cruisers which are the mainstays of the fleet, the Imperium could just choose to use a smaller warp core suitable for this ship's size and focus on mass-producing the Long Serpent to replace basically every other class of ship except battleships , Cobras, and carriers. Fewer would be made but, unlike video games, swarming a capital ship with escorts does not work at all. The escorts are slaughtered and the capital ship like this one is left unharmed. But doing this would require common sense, which is [[Heresy]]. Like properly using the Invincible-class must be.
**'''Mercury Battlecruiser:''' Another fast Battlecruiser. It's a cruiser with a Battleships's engines. Nothing more.
**'''Hades Heavy Cruiser:''' A long-ranged brawler. Carries Broadside Macrobatteries and Dorsal and Prow Lances. Got phased out like most keel-built designs, but Chaos still uses them.
*'''Lance-boats:'''
**'''Acheron Heavy Cruiser:''' Designed to test new Lances and Macrobatteries. The Imperials only built one, which went traitor. Carries Broadside and Dorsal Lances with Prow Macrobatteries.
*'''Carriers:'''
**'''Mars Battlecruiser:''' In a word - Mediocre. Some Imperials say it's versatile due to its diverse weapons loadout but in reality it makes it an awkward duckling to use. The Nova Cannon and Launch bays would be good on a ship holding back and harassing enemies at range and yet it has Macrobatteries and Lances which are great for brawling. So if you sit back and harass or go in and brawl, you're wasting half your ship. The Imperial Navy never really got on with it either and so it has gone out of production on most Forge-Worlds. Which is a shame because if they would replace the macrobatteries and lances with larger, long-range lances, and a great number of small, short range weapons batteries for fighter support and self-defense respectively, this would be a great ship in any fleet. It's nova cannon clears a hole in the enemy escort screen, the attack craft rush through to wreck the weapons and engines of light capital ships while long-range lances assist other Imperial ships in slaughtering targets of opportunity. The destroyed enemy light capital ships leaves all the other big ships vulnerable to mass, concentrated torpedo attack from friendly ships. Attack craft return to the fight to tear up the no-doubt seriously damaged enemy big ships and lances win the day. Then just send in friendly light capital ships with attack craft support to finish off the surviving escorts. That would almost make this ship into a sort of miniature "I Win" button. Almost. Especially in a squadron of two, as they could assist each other against any opponents that slip through to them with their combined, close-range firepower, lances, and whatever attack craft they kept back for defense ripping the enemy weapons and engines apart to let the close-range macrobatteries have fun.
**'''Dominion Battlecruiser:''' Basically a fixed Mars, some tech priest got it in their head that, maybe, it'd make more sense to replace the Macrobatteries with Lance Batteries instead, making it a dedicated support ship, harrassing enemy ships at range whilst the big guns go out and fight. Apparently not that successful, a number were used at the Battle for Maccrage (Of course the fucking Smurfs get them) against the tyranids, though apparently they all got fucked up and have been in drydock since, which is why up until now no-one's seen them.
**'''Styx Heavy Cruiser:''' A pure carrier. Has Broadside Launch Bays, Dorsal Lances and and Prow Macrobatteries. For some reason the Imperial phased it out for the Mars, so only Chaos uses them now.
**'''Hecate Heavy Cruiser:''' An attempt to replace the Styx. Swaps out some of the Launch Bays for Macrobatteries. Believed to have an inherent design flaw that made them go traitor, so they were decommissioned.

===[[Imperial Navy Cruiser|Cruiser]]===
Cruisers are the bread and butter of the Imperial Navy. Much larger than escorts and light cruisers, but less rare than battleships, cruisers are what the Imperial Navy (and Chaos and Xenos) use to fight their campaigns across the stars. Thus far, all Imperial Cruisers have been shown to utilize the same hull-type: a squat armored prow in front, capable of mounting a prow-mounted weapon system, and a big bunch of engines in the back, with baroque and Gothic architecture in-between. Most cruisers can effectively be placed in four categories:
*'''Basic:'''
**'''Lunar:''' The Lunar. You've heard so much about it and now you want to know what it makes it the standard Imperial Cruiser. First of all, it's one of the oldest designs still in use by the Imperium and is so easy to build that even less advanced worlds can produce them. They're quite versatile due to their weapons loadout (a balanced build of Macrobatteries, Lances and Torpedoes) and make up the backbone of Battlefleets throughout the entire Imperium. This is the cruiser against which all other cruisers are measured.
**'''Emasculator:''' Considered a failure by the Imperium at large, Emasculators have the same basic load-out as the Lunar, but are keel-built, lacking the armored prow and replacing the torpedo tubes with more weapons batteries. This means they require different tactics to a Lunar, using their speed and longer ranged weapons to pound ships from a distance. As this fits with Chaos tactics more than Imperials. most of them ended up as traitors. [[/d/|The name Emasculator is due to them being seen mostly as Slaaneshi ships, their original name is unknown.]] The fact the Imperium keeps trying new ships built on the normally Chaos style hulls implies that usually it must work out just fine since otherwise it would have been banned by now. So, there are probably many cool looking keel-based Imperial ship classes floating around we'll never catch wind of ever.
**'''Slaughter:''' A special type of Cruiser, the Slaughter-class has a more powerful drive called the Scartix Engine Coil, but lacks prow weapons. Armed with short ranged, but powerful lances and macrobatteries, the Slaughter is designed to get in close, blast away and retreat. Unfortunately, the Imperium can't build them anymore because one went traitor and destroyed the plans for the Scartix Coil. It is unknown if they were always called the Slaughter-class or were renamed when most went traitor. Considering the usual lack of intelligence in the Imperium's leadership, it was probably called something worse, like the "Traitor-class" or something and then the Imperium wss shocked when they lived up to it. Really, would you be surprised if the Imperium did that?
**'''Inferno:''' A earlier counterpart to the Carnage-class, carrying more lances in exchange for some Macrobatteries. Had the same difficulties as the Carnage and was mothballed, though a few went renegade beforehand. Rare example of the Imperium learning its lesson. Still too stupid to realize that using cheaper-after-a-few-centuries-than-manual-labor auto-loaders would've fixed the problem for both ships.
*'''Lance-boat:'''
**'''Gothic:''' Another variant of the Lunar Class, the Gothic is designed as a heavy Lance gunship. Due to the amount of Lance Weaponry it carries, it can easily deal with ships of its own size or larger but often does require an escort or a partner to strip enemy void shields first in order to use its own weaponry to the maximum effect. When supported and used correctly, Gothic Cruisers are the most efficient way to deal with enemy capital ships.
*'''Ordnance-boat:'''
**'''Dominator:''' A variant of the Lunar Class, the Dominator is designed primarily for planetary bombardment and assault. Not generally used in fleet actions even though it can provide support with its Nova Cannon when necessary. After one Dominator fucked over a Chaos Cruiser with said Nova Cannon during the Gothic War, the Navy took note and started making more Dominators. [[Awesome|Additionally, another Dominator came close to destroying the Terminus Est (''aka the toughest Battleship in the galaxy''), before being destroyed.]] The Dominator possesses the same armament as the Retribution-class battleship but lacks the range of one. This is fine, though, since it's meant to get close to the enemy like most Imperial ships anyway. Basically, if you get in range of this thing, ''you're going to die''.
*** From Lexicanum 40K: "Captain Straden of the Depth of Fury defended the shrine world of Kathur to the death, and came very close to destroying the Death Guard ship Terminus Est. As it was, he and his crew vaporised several of its decks and destroyed scores of escort ships before finally succumbing. Ironically, no Imperial souls survived to tell the tale."
**'''Tyrant:''' The Tyrant was originally intended as a stand-off vessel; it would stay at long range and bombard enemies from afar with superfired plasma weaponry. Unfortunately, due to design compromises where it mixed both short range and long range weaponry to save on power, it wasn't really deadly enough at long range to do its job. Therefore the Imperial Navy is trying to replace the short range weapons with ancient Long-range weaponry (that doesn't use a lot of power) recovered from Space Hulks or Renegade Ships. The Hull itself is a rather effective design and so the Tyrant has become very popular with Rogue Traders who generally replace all of the Plasma Weaponry in order to have more power available compared with other cruisers.
**'''Relentless/Carnage:''' Another attempt at a fleet support ship with Plasma weapons, the Relentless ended up with technical difficulties and, when these were overcome, [[Heresy|most ships ended up turning traitor]] [[Fail|(including the lead ship of the class)]]. [[Tzeentch|This is theorised to be due to something wrong with the geometry of the ship's design]], as the Relentless-class is keel built, like most older ships (This also means the Relentless lacks an armored prow and torpedo tubes, carrying more plasma batteries instead). The tendency of these ships to turn to Chaos, along with changing tactics, led to the class being renamed the Carnage-class and mothballed in favor of the Tyrant-class, though their speed means they suit Chaos tactics famously.
*'''Carrier:'''
**'''Dictator:''' A Carrier retrofit of extremely damaged Lunar Class Cruisers. If a Lunar class has its lance weaponry destroyed, it's quicker, easier and cheaper to replace those with heavy launch bays for strike craft. This makes it quite versatile and able to deal with virtually all situations and interestingly enough, makes it more effective than the original Lunar Class at everything except fighting as a ship of the line. Unfortunately, the Lunar Class is designed for fighting as a ship of the line, so Admirals dislike Dictators.
**'''Jupiter:''' A kitbashed design, converted from other classes of cruiser that have been heavily damaged in battle. By stripping out all the damaged components and replacing them with launch bays, you get a pretty sturdy carrier. Just don't let the enemy get anywhere near it. Apparently the Imperium doesn't build these normally at all, likely because they are absolutely shit at defending themselves from other Cruisers.
**'''Devastation:''' Deviating from the standard Carrier design, the Devastation-class carries Lances instead of Macrobatteries. Mostly turned traitor or mothballed, as they lack armored prows and torpedos; and are keel-built. Chaos likes them, as they can pack them with mutants and sit back to spam assault boats and lances at anything that looks at them funny.
*'''Other:''' Various other cruiser types exist, but are rarer.
**'''Ambition:''' Custom-made Cruisers for the exceedingly affluent - it's the Rolls Royce of the Cruiser World. Most Rogue Trader ships are second-hand, battle-scarred, tired and worn ex-navy vessels but the Ambition is not. It's the only cruiser class that can be bought brand spanking new by Private parties in the Imperium and each one is unique and built to the customer's specifications. These exclusive ships, whilst still cruisers and deadly in their own right, are stately homes and status symbols. Some durability sacrifices have been made in order to make them the most opulent and luxurious ships on the market but for eccentric people like Rogue Traders, it's generally worth it.
**'''Conquest-Class Star Galleon:''' Built for the very first Rogue Traders on the orders of the Emperor himself, the Star Galleon is an ancient and noble design. Whilst not considered heavily armed by modern standards, they're still formidable opponents and yet as specialist exploration vessels they are able to operate independently for many years and can transport greater quantities than other Cruisers. In effect, it's a cruiser fused with a transport and looks fucking amazing.
**'''Murder:''' The predecessor to the Lunar. Differs by being keel-built, exchanging their torpedos for Lances and having more powerful macrobatteries. The majority that appear in modern 40k are Chaos-aligned, as the Imperials mothballed theirs in favor of the Lunar. A few carried lances as well as Macrobatteries, meaning they don't fit into any category. As with the Slaughter, it is unknown if Murder-class is their original name or they were renamed.

===[[Imperial Navy Light Cruiser|Light Cruiser]]===
Smaller than true cruisers, light cruisers are used in two ways. Either you use a fast, maneuverable light cruiser like the Dauntless to add some extra firepower to a scouting squadron or long-range patrol, or you use a pocket cruiser like the Voss light cruisers to add some heavy firepower and armor to a convoy, fleet, or base. The advantage of the light cruisers are that they're cheaper to build and operate than real cruisers. Another departure from real nomenclature. In real life, “light” cruisers were less armed and armored normal cruisers made to make up for losses, especially in America after Japan’s initial attack. After the industry fully turned to wartime manufacturing, the light cruisers’ changes were recinded and they were just normal cruisers again. However, with the introduction of heavy cruisers, the normal cruisers again were named “light” cruisers to avoid confusion. In 40k, however, light cruisers are very distinct and fill a unique niche. Like the Cruiser, they fit into a few base categories.
*'''Basic:''' Same as its larger sibling, a Jack of All Trades.
**'''Dauntless;''' The standard Light Cruiser of the Imperium; it's a Jack-of-all-Trades. You can't go wrong with the Dauntless even though other Light Cruisers may be better for certain tasks. Considered 'scouting' cruisers, these make up the bulk of Imperial Patrol Squadron leaders.
**'''Defender:''' A convoy escort variant of the Dauntless, with added dorsal weaponry.
**'''Endeavour;''' A 'heavy', Light Cruiser, designed as a stop-gap between the 'lighter' light cruisers and true cruisers. Whilst they can slug it out in a fleet fight, they can easily be overwhelmed because they simply aren't cruisers and don't have the equivalent fire-power or hull integrity. As an added titbit, most of Battlefleet Koronus' patrols consist of an Endeavour and a pair of frigates.
**'''Lathe-class Monitor-Cruiser;''' An Adeptus Mechanicus Light Cruiser designed around deep space exploration and extreme self-reliance. These ships, when properly outfitted, can operate for decades without returning to imperial space for resupply. These would make up the bulk of Explorator fleets.
**'''Secutor-class Monitor-Cruiser;''' An Adeptus Mechanicus Light Cruiser designed to excel at the art of war. Tougher than all of the other Light Cruisers and yet still more mobile than true Cruisers. Due to being designed from the ground up to be a Warship, this Light Cruiser is fitted with Cruiser sized Void Shield Generators.
**'''Siluria;''' Three-quarters the cost of the Endeavor, and about three-quarters the ship. Standard weapon batteries only, no fancy frills to speak of. Cheap and effective, at short range, to catch enemy torpedoes.
*'''Lance-boat:''' Also the same as the Cruiser version, though some have weak weapons batteries for better defence.
**'''Endurance;''' Light Cruiser with just enough guns to claim it has them, lance batteries and a couple of torpedoes. It's the lance half of a Lunar, nothing more.
*'''Carrier:''' More useful as a Light Cruiser, as it can act as backup for patrols.
**'''Enforcer:''' A carrier variant of the Dauntless. Designed to maintain control of rebellious planets via intimidation [[Grimdark|(and possible orbital bombardment)]]. Given one managed to stop the rebellion of an ''entire sub-sector'', its a shame the Imperium doesn't build more of them.
**'''Defiant;''' A carrier variant of the Endeavour. It's quite versatile (by virtue of being a carrier) and so has found a home in many Rogue Trader houses but unfortunately the Imperial Navy doesn't consider it as useful because they can't stand by themselves and require an escort. Due to being based off of the Endeavour, it's relatively well armoured for a Light Cruiser and that does help with its survivability.

===Ironclad===
8 kilometer long battering rams. No, really. Tyranids and Orks are busy taking notes.

===[[Imperial Navy Escort|Escort ships]]===
Escorts are the smallest armed vessels available to the Imperial Navy. These ships are normally assigned sector patrol duties or perform as escorts for much larger ships. In fleet engagements they will also act as scouts, ranging out in front of their armada to verify enemy ship numbers and locations. They are generally clasiffied as either frigates, or as destroyer ships.

====Frigates====
Ranging from about 1.4-2km long. They are used for all sorts of duties from convoy escorts to attack or patrol squadrons. Ironically named, as in real life Frigates were the same as Cruisers (which were not Ships of the Line).
*'''Basic:''' Laser batteries only, maybe some Torpedoes if you're lucky. Named after types of swords.
**'''Sword Frigate:''' The most common warship in the Imperial Navy, and one of the simplest. No torpedoes or lances to distract you here; a Sword puts two massive laser batteries behind a pointed armored prow and cuts into enemy formations like [[C.S Goto|a multi-laser through canon.]]
**'''Falchion Frigate:''' A new (245 years old) class of escort ship built by [[Forgeworld|Voss Prime]]. Slow as balls but still capable of firing torpedoes. While Cobras are used offensively in fleet actions, Falchion's are designed to be convoy escorts and stick close to larger warships to defend them from enemy escorts. Effectively a Voss-pattern Sword with torpedo tubes and one laser battery.
**'''Claymore Corvette:''' Designed entirely around escorting vulnerable transports and protecting them against light raiders in order to allow true Frigates to accompany more valuable ships such as Battleships, Battlecruisers and Cruisers. The Claymore Corvettes are easy to mass produce and maintain and are exceedingly common in the private sector, as they are simply a discount Sword.
**'''Turbulent Heavy Frigate:''' Heavy Naval Escorts; these things have comparable armour to cruisers. They're built to sally forth ahead of the main fleet and win skirmishes against enemy scouting forces and vanguard elements. They've garnered a reputation for being lucky; they've contributed to many glorious victories and survived catastrophes that other ship classes have not. Their only downside is that they have rather antiquated communication equipment, probably equipped for durability, not ease of use.
*'''Lance-boat:''' Rarer for Frigates, as they need a Prow slot to mount a Lance.
**'''Firestorm Frigate:''' A Sword-class frigate with a prow-mounted Lance replacing one laser battery. Gives the Sword some extra anti-ship punch that it dearly needs. It's also two hundred meters longer than the Sword-class as a result. The Navy does not like the Marines having them, for some reason.
**'''Thunderbolt Heavy Frigate:''' Not much information on this one, but implied to be a Lance version of the Turbulent, like how the Firestorm is the Lance version of the Sword.
**<s>[[Derp|Given the general naming scheme for Frigate classes is naming them after weapons (Claymore, Sword, Falchion, Gladius etc), the Firestorm would make more sense being called the ''Lance''-class due to its role.]]</s> It's pretty clear refits do not follow the same naming conventions.
*'''Ordnance-boat:''' Mostly upgunned Frigates. Can carry a mix of macrobatteries and small lances.
**'''Tempest Strike Frigate:''' Specialized Brawling frigate designed for devastating enemies at close range. Basically a Sword with a triple armoured prow and heavy short-range broadside batteries. They're often equipped with Assault Boats and Barracks for boarding actions.
**'''Havoc Merchant Raider:''' Small, yet fast raider sized vessels whose impressive firepower came at the expense of armor. Glass Cannons, in large squadrons these can easily overwhelm larger vessels by weight of fire.

====Destroyers====
The most common warship class. Their tasks range from scouting to shuttling VIPs or fighting in fleet engagements in large squadrons. Most pirates use these speedy, nimble vessels to prey upon transport ships.
*'''Basic:''' Usually mounts Prow Torpedoes and a Macrobattery.
**'''Cobra Destroyer:''' The PT-Boats of the Imperial Navy. Small, fast, and lightly armed, their one purpose in life is to fire shoals of torpedoes from 3-8 ship squadrons. A great part of the Imperium's military advantage (in fluff and [[Battlefleet Gothic|on the tabletop]]) comes from all the torpedoes they can fire at the enemy, and the Cobras are a big part of that.
**'''Infidel Raider:''' Was meant to replace the Cobra, but the plans [[Blood Ravens|were stolen]] by Chaos. Armed with Prow Torpedos and a Macrobattery like its predecessor, though some Chaos fleets upgrade them to Heavy Raiders by adding another Macrobattery.
**'''Iconoclast Destroyer:''' If there ever was an Guardsman of starships, the Iconoclast is it. A destroyer so shitty the Navy doesn't want it, the Iconoclast mounts 1-2 macrobatteries and is used by Rogue Traders, Chaos and Pirates. Notable for being one of the few ships to have a forward placed bridge, likely due to the smoke-stack like pylons along its spine.
*'''Torpedo-boat:''' Why waste space on pop guns?
**'''Viper Destroyer:''' Given GW's naming conventions, it was inevitable somebody would do this. Not to be confused with the Sloop below, this is a variant of the Cobra where the guns are replaced by torpedoes. Weak against escorts but deadly in numbers against capital ships. Use [[Boarding Torpedo|Boarding Torpedoes]] for hilarious results.
*'''Lance-boat:''' Rather rare among Raiders, as most use their Prow slots for Torpedoes.
**'''Apostate Heavy Raider:''' A variant of the Infidel. Somehow those heretics managed to shove a full sized Lance into a Dorsal slot, which only Light Cruiser and bigger can normally manage.
**'''Idolator Raider:''' Also known as the "WTF is this" ship, the Idolator is the lovechild of a Infidel, a Firestorm and Xenotech. Has a prow lance and a macrobattery.
*'''Other:''' Mostly weak scouts.
**'''Viper Scout Sloop:''' Smallest warp-capable ship in mass production. It is an exceedingly fast scout ship with ridiculously powerful realspace engines and high-tech auspex scanners. In support of Naval Operations these vessels would burn into enemy territory at high speed, collect as much information as possible and then warp back to friendly territory. Unfortunately they are so specialized that they can't do much else apart from that.
**'''Rudense "Class":''' A small ship designed post Gathering Storm to be as fast, heavily armed, and densely armoured as possible, which they do with aplomb. You may ask yourselves, why are they not used in more regular combat roles? Well, the answer is that they are a specialised orbital insertion ship - designed to get as close to the atmosphere of a heavily defended planet as possible, drop it's cargo of primaris marines into the top layer, and get out of there. Whilst this may seem too specialised to be practical, few enemies are ready for half a company of marines dropping in to their base unexpectedly. (Nb - the class hasn't been formally named yet but the only example of it thus far was named the Rudense).

===Aircraft===
As part of the reforms falling the Horus Heresy the Imperial army was not just split into regiments to insure that no one imperial army could be self sufficient if it fell to heresy or rebellion, the army was also split from it's air power which was given to the Imperial navy. Strictly speaking all atmospheric aircraft are also part of the Imperial Navy, with only [[Phantine Air Corps| few general exceptions]].
*'''[[Fighter]]:''' The fighter's main role is to stop enemy torpedoes and bombers before they can [[anal circumference|rip your flying cathedral multiple new assholes]]. Comes in different models like the [[Fury Interceptor]] or the Thunderbolt Fighter. The main difference is that some can enter a planet's atmosphere to dogfight and/or strafe ground targets where others are limited to space combat.
*'''Bomber:''' Basically reusable torpedoes. Come in different models like the [[Marauder Bomber]] and the [[Starhawk Bomber]], but again the main difference is that some can dip in a planet's atmosphere and drop bombs on ground-pounders where others are space-combat only.

===Armed Freighter (in the Battlefleet)===
Ships bought, borrowed or stolen and then armed in the misguided attempt to boost the strength of a fleet in desperate need of ships (instead of simply using the legio cybernetica to make robots to do the monotonous manual labor so 90% of the hundred thousand crew members can be spread out amongst a hundred more warships)

===Fire Ship===
A fancy name for a fuckheug bomb. A old, damaged or for whatever reason no longer usable ship is packed to the brim with explosives and flown straight into the heart of the enemy formation. Again, Orks are busy taking notes for their Roks. Contrary to what you might think from the Imperium, this is not a suicide assignment. A skeleton crew is used and supplied with plenty of escape pods/lifeboats. The crew evacuates and the ship detonates after they are far out of the danger zone. Some captains decide to go down with the fire ship anyway. Or they mindfuck some penitents to stay and guide it to the best point of detonation. The Imperium isn't short on criminals and/or desperate underclassmen/mutants.

===Non-Warp Capable Vessels===
Vessels incapable of interstellar travel. All but the most primitive Imperial planets have them.
*'''System Ships:''' Civilian ships that do all the civilian stuff like ferrying, mining and transport. As nobody would buy models of them, [[GW]] never bothered to flesh out their canon. If armed, they are dragooned into the System Defense Force during invasions.
*'''Defense Monitor:''' Essentially, a mobile gun emplacement in space. Slow and small, it diverts all its power into the battleship-sized gun it carries. Crewed by regular Imperial Navy personnel and used to augment existing defenses.
*'''System Defense Vessel:''' The primary unit of a System Defense Force aka the [[Planetary Defense Force|PDF]] in space. Nobody knows what they look like or even what capabilities they have. It is assumed they are lightly armed vessels usually used in police actions and customs enforcement. In times of invasion, they use hit and run tactics as best they can until they die.

===Logistic Vessels===
Ships used for the transportation of cargo or individuals. The majority of Imperial ships would fall into this category.

*'''Carrack-Class Transport Ship;''' A newer version of the Conquest Star Galleon. It's a hardy vessel that can defend itself quite well against raiders. The profile even looks like a Military Vessel so opponents who can't distinguish between Imperial Ships could be scared off.

*'''Goliath-Class Factory Ship;''' An Adeptus Mechanicus vessel designed to harvest plasma from Stars. These ships supply the fuel for the entirety of the Imperium. Other ships can be fitted with Plasma Scoops to top up their own tanks but this is the true fuel-harvesting-workhorse of the Imperium.

*'''Jericho-Class Pilgrim Vessel:''' Refinery ships that have been converted into personnel carriers, the majority of which will be transporting poor-er passengers. Can't really defend itself but usually not even worth the bother for pirates.

*'''Loki-Class Q Ship;''' Converted Cargo ships designed to sacrifice some space for added weaponry. They can serve as Convoy defence in a pinch and can surprise the odd pirate who may underestimate them.

*'''Orion-Class Star Clipper;''' Blockade runners through and through. They're designed to transport low-volume but high-quality goods, even through hostile space. Speed is the name of their game. Hell, these things can put some Eldar ships to shame.

*'''Universe-Class Mass Conveyor;''' Think Super-Tanker in space. It's the largest standardized Cargo hauler in the Imperium and is 12km long. It looks freaking awesome too.

*'''Vagabond-Class Merchant Trader;''' Rather small cargo vessel but extremely common. As if to assist with its 'commoner' theme, it makes you yawn just looking at it.

==Adeptus Mechanicus ships==
Being in charge of manufacturing the warships for the other departments of the Imperium, obviously the Adeptus Mechanicus would also have fleets of its own. The official Mechanicum body that constructs and operates spacecraft is known as the Basilikon Astra. Because the Quest for Knowledge can involve long & dangerous travels into unexplored space, it is important that they be heavily armed and armored, so the Adeptus Mechanicus ships generally are overall of higher quality than standard ships, with better tecnology, weapons, and shields. Though the total number of ships the Adeptus Mechanicus has at its disposal dispersed among its many forge worlds is far outnumbered by that of the Imperial Navy, it goes without saying that those responsible for all starship construction reserve for themselves among the most powerful and best-equipped warships encountered anywhere in the Imperium.

*'''[[Ark_Mechanicus|Ark Mechanicus:]]''' If battleships are literal void-traveling cities, then Ark Mechanicus are void-traveling factories or massive laboratories, with industrial capabilities rivaling that of many hive cities, with kilometre upon kilometre of manufactoria, refineries, crackling Plasma Reactors and laboratories, test ranges, chemical vats and gene-bays. This kind of battleships are incredibly large, nigh-mythical ships that are said to endlessly search the stars as part of the Adeptus Mechanicus Quest for Knowledge, being led by a Venerated Archmagos Explorator. An Ark Mechanicus is outfitted with the most powerful weapons available to the Imperium, generally having a balanced set of macro-cannons, lances, launch bays & a Nova Cannon; Because the search of STC into the unknown can be THAT dangerous.

*'''Adeptus Mechanicus Cruiser:''' Besides vanilla cruisers, the Mechanicus have its own original Cruisers & Light Cruisers, that have better equipment than Imperial Navy cruisers, many times they tend to have nova cannons and that they use servitor slaves instead of human slaves, and occasionally use auto-loaders. In resume, take Imperial Cruiser but quit the typical imperial armored prow, make it shinier, give it better weapons, and can put a nova cannon as a plus.

==Important Details==

===Crews===
''Navy crews are made up of officers, techpriests, slave drivers, and slaves.''

A bit of an over-simplification, but broadly true. Due to the Imperium's aversion to AI and Automation each ship needs at least thousands of people to man it. Whenever the crew count gets low, the Imperial Navy sets up fake strip clubs on a planet claiming "Free Hookers" to lure in unsuspecting men (and the occasional woman). Once a future crewman steps in, he's knocked out, bound, gagged, and taken to the ship, [[grimdark|where they'll slave away the rest of their soon-to-be-short existence]] doing everything needed to make flying through space and fighting in the void possible.

This includes dragging shells the size of houses into cannons while being whipped. Still, at least for the crew sex is allowed, in fact encouraged, if for no other reason than maintaining the crew complement. Seriously, whole fucking cities and civilizations arise from the more massive ships, every bit as intricate as a long lived Hive City. [https://www.youtube.com/watch?v=ax7wcShvrus Here is an idea of how it works, right up to the Roman armor, whips and beatings.] Oh and apparently besides whole civilizations, there are whole civilizations of mutants around too. They can more or less settle new worlds for da [[Emprah]] by simply disgorging their excess population, which the crew is probably all too happy to do.

One area where fluff [[Black Library|hasn't been consistent]] is in the uniform worn by Imperial Navy crewmen. Some sources suggest that uniforms are divided by segmentum of the Imperium, while others suggest that it is a sector-by-sector fashion choice. Given the scale the of the Imperium and the fact that Navy fleets are already identified by hull color, it's probably on a segmentum basis, but [[Games Workshop]] doesn't care enough to make a decision about it. For the ranks of the aforementioned shell draggers at the bottom of the naval hierarchy they'd wear a motley collection of their old civilian clothes and whatever they could scrounge up and sew together.

===Travel===
The ships of the [[Imperium]] travel through the [[Warp]] using what's called a warp drive to get to where they're going. However, this isn't your happy, fancy tunnel-of-light like in Star Wars, or everything-moves-fast Star Trek, it is an alternate dimension full of [[Chaos]]. In order to avoid being turned inside-out (think Event Horizon) and getting hentai-raped by every daemon in the warp, the ships rely on what is called the [[Gellar Field]] to keep the [[furries]], undesirables, and various other evil beings out of their ship when traveling through. The Baroque decorations are also implied in helping to ward off said daemons. They rely on a [[Navigator]] that uses the [[Empra]] as a beacon to safely navigate the Warp, hence the title "Navigator".

==Ranks in the Navy==
While the Imperial Navy uses a lot of the ranks in similar fashion to modern militaries, they invariably hold to a more archaic form and are not equivalent to modern day ranking systems. Particularly since it's quite clear that commissions in 40k can often be purchased rather than earned, and that a "Warrant" would most likely hold to the original term and be an "officer by appointment" rather than an enlisted grade. Though considering the immense variety of units within the Imperium, this may not necessarily be the case galaxy-wide, so all options are equally valid. Also, the ship commander will generally be referred to as Captain internally for the sake of simplicity, except in Astartes fleets where they are called shipmasters to avoid confusion regarding the actual rank of Captain in the Astartes.

===Officer Ranks===
*'''Lord-High Admiral of the Imperial Navy''' - This guy is a [[High Lords of Terra|High Lord]] and is the single dude responsible for the '''ENTIRE''' Imperial Navy, though likely he doesn't do much other than delegate to his subordinates and attend tedious High Lord meetings.
*'''Lord-High Admiral''' - There are five of these guys, one for each Segmentum. While they're probably never anywhere near the front lines they probably have more to do, since its their job to oversee the deployment of fleets and materials from sector to sector.
*'''Lord Admiral''' - The guy in charge of a sector fleet who gets direct command of vessels and formations. You see these guys in the fluff quite regularly when "key" worlds ''(like Armageddon)'' need defended or attacked.
*'''Solar Admiral''' - Often a ''terminal'' rank... no really. Occasionally regular Admirals who do good jobs can put themselves forward for promotion to this position, which needs to be approved by the Lord-High Admiral of their Segmentum, then the officer needs to travel to Terra be reviewed by the Lord-High Admiral of the Imperial Navy. Obviously this can take a very, ''VERY'' long time to approve. So they might often be [[Grimdark|dead before the paperwork gets rubber-stamped]]. If they do get approved they are likely to get promoted straight up to sector commander (see Lord Admiral) as a position will probably have opened up while he was waiting. More rarely, Solar Admirals can get sent on "detached duties" which is basically a license to do as they please with their independent fleets.
*'''High Admiral''' - Commands several group of naval fleets (e.g. Battlegroups), often the most senior Navy officer in a Crusade but the things these fucks usually do is just having snacks with their Imperial Guard counterparts and leaving the combat duties to their subordinate Admirals
*'''Admiral''' - Gets put in charge of a fleet and told to oversee some subsectors. He's usually the highest of the "front line" ranks and much of his time will be on active duty patrolling his assigned region.
*'''Vice Admiral''' - Fleets traditionally get split into three parts, with the highest Admiral taking up the portion containing the larger ships, while the "Vice" Admiral takes the "Vanguard" portion of faster moving ships.
*'''Rear Admiral''' - the third portion of a fleet would be the "Rearguard" and usually gets assigned to the youngest/least experienced Admiral in the fleet. His job is usually the quietest one as he gets the mop-up and repair duties.
*'''Commodore''' - an experienced Captain in command of a squadron of capital ships. It's traditionally only a temporary rank, as capital ships don't always get assigned to each other the same way that escorts do. But the realities of war often mean that ships stay together for extended periods, often well beyond the lifespans of generations of captains.
*'''Lord Captain''' - not actually a rank, but an honourific applied to Captains of detached vessels operating independently. The '''"Lord-"''' part implies that they operate with the full authority of the the Imperial Navy when they act so they can deal with outside organisations (like planetary governors, Space Marines or Imperial Guard) on relatively even footing. Sometimes also known by the more archaic term of "Flag-Captain", since as the commander of a detached vessel they figuratively carry their own flag.
*'''Captain''' The commander of a single capital ship or the lead starship in an escort squadron.
*'''Commander''' - Usually the commander of an escort vessel. Is also the ranking officer on board orbital space stations. It also gets used as the terminal rank amongst Pilots, since small attack craft all fall under the remit of the Navy; so a '''Wing Commander''' would get command over all pilots based on a single carrier.
*'''Lord Lieutenant''' - The second-in-command to captains of capital ships, bizarrely Commanders don't hold that role and hold their own positions. Thankfully because a chain of command exists in any military, despite a Wing Commander holding higher "actual" rank over a Lieutenant on a carrier vessel he would not hold any higher authority on that ship than his duties allow for.
*'''Lieutenant''' - a "working" rank. Either holds command over small system vessels or acts as second in command to Commanders of escorts, or as department heads on Capital ships. They are also Squadron leaders amongst pilots.
*'''Sub-Lieutenant / Ensign''' - Team leaders or attack craft pilots
*'''Midshipman''' - Apprentice officers who haven't passed any exams or earned any responsibility, they would exist below the Warrant Officers in terms of authority, despite holding a commission. Midshipmen are commissioned from Imperial Nobility as part of the [[Administratum|Imperial Tithe]] ''(which can mean virtually anyone gets the job if they send their useless heirs just to keep the best ones at home)'' but they are also assigned from the [[Schola Progenium]]. In addition, Midshipmen also may be taken on as a personal favour from the Captain of a vessel if he knows the family. This echoes the ancient real-world practice of young noblemen showing up while the vessel was in dock with a letter from their family and being granted a commission on the Captain's say-so.

===NCO Ranks===
*'''Ship Master''' - the most senior Warrant officer on board a starship, also quite possibly the busiest man on the starship. It's his job to maintain the logs, update stellar navigation charts, oversee ships stores and order supplies, and command a hangar deck if there is one. Basically he's the guy who knows the ship better than anyone. In real-world historical usage, this guy would have an authority equivalent to a Lieutenant on board a starship, and would "mess" ''(ie: occupy the same space)'' as the other officers do.
*'''Bosun''' - ''(Shorthand for Boatswain)'' The NCO directly responsible for all of the common crew members, including [[Commissar|maintaining discipline]]. Despite his position, his actual rank may vary depending upon the size of vessel or operational requirements, in practice it never really matters since he's unlikely to ever meet another Boatswain. ''(real-world Boatswains are typically petty officers or warrant officers, but could be of any rank. They held responsibility over all areas of the ship other than Engineering, which was left to the Chief Engineer, as if the bosun disciplined/executed/imprisoned a skilled crewman from that department the ship could be crippled because of it)''.
**Note that most Capital Ships, but not all Escort ships, may have an actual Naval [[Commissar]] on board in this role, tasked with maintaining discipline up to and [[Blam|including]] the Officer compliment.
*'''Chief Warrant Officer''' - Also called "Chief Petty Officer" on some vessels. Will often be given command of important ship sections ''(like Chief Engineers, helmsmen, or auspex control, as these are are critical to ongoing operation of a starship)''
*'''Warrant Officer''' - You'll find lots of guys of equivalent rank on a ship, in command of various operational sections keeping the ship running at all times:
**Masters of Ordnance - make certain that Torpedoes and Attack craft (if any) are fueled and maintained.
**Master Gunner - have responsibility over all of the weapons batteries through the Gun Captains and make ensure they are loaded and fired when required.
**Master-at-Arms - responsible for all "small" arms on board a starship, overseeing all Sergeants-at-Arms, as well as maintaining order over any barracked Guard regiments currently in transit.
**Master of the Vox - making sense out of the bazillions of messages that run through the bridge at any given moment both internally and externally ''(crews can get pretty massive, and a lot of traffic can come through at once)''.
**Steward - the guy who keeps everyone else well fed.
*'''Gun Captain''' - Funnily enough, the man in charge of a single gun crew. Makes sure that the weapon is taken care of, is reloaded quickly enough, and is accurate when asked to fire. All of that comes back to this guy.
*'''Sergeant-at-Arms''' - Man in charge of the weapons lockers and leader of boarding parties, as well as maintaining ship-board security. Usually they are transferred from [[Imperial Guard]] regiments so that they don't have any prior association with the crew.
*'''Armsmen''' - Crewmen trusted to carry weapons more than a standard issue Lasgun/Laspistol. They are not true soldiers as offensive boarding actions tend to be rare. So these guys still have their own regular responsibilities on board ship. Since they are trusted more, they have slightly more freedom to move around the vessel as well, though most Imperial employees really don't want the job, since it means they get scrutinised more, or they could end up beating up their buddies.
*'''Voidsmen''' - the lowest rank of crewman on board a Naval Starship above the [[Servitor]]s unless the Captain is cool with slavery. If they have a skill or a trade they may be referred to as '''Able Voidsmen''' which is an official rank that might require examinations. Additionally, if they show leadership qualities they might be promoted to '''Leading Voidsman''' and put in charge of work gangs and be considered for promotion to Warrant Officer if a position opens up.

==Notable Problems==
These are problems some have with the Imperial Navy and their fluff....

===General Logistical Problems===
The big problem that the Imperial Navy has is that it's the only organised navy in the galaxy that's trying to defend its massive amounts of space. To do this takes vast numbers of ships but rather thinly spread out. Given the problems of warp travel it's also extremely hard to reinforce friendly fleets under attack. The foes of the navy come essentially in two flavours; raiders who might just manage to scrape together a few converted transports (building even escort-sized ships is a huge undertaking, akin to building damn near the entire American Navy combined from iron ore and making it fly) which take an escort squadron to murder, and huge organized invasion fleets that take a whole fleet to fight. These combine together to mean that outside of fleet bases and important strategic worlds there is nowhere in the Imperium that is actually well-defended. At best a fleet has to be formed and sent out and they could arrive months later. Travel takes a lot of time, and out in the void it can be extremely hard to know what you are actually fighting against, especially since the enemy tend to kill anyone who tries to look at them. So when there's a large enemy force that you absolutely must fight (not fighting is much preferable) you don't just band together whoever was within shouting distance of the flagship and go murdering, you pull together every single vessel in the sector and hope to the Emperor it's enough to do the job.

TL,DR: Acquiring a force sucks when command thinks paperwork and red tape are forms of worship and maintenance thinks the toilet needs a prayer before it is unclogged.

Warships genuinely are vast things and obscenely expensive and risking them at all in major actions is not something anyone does lightly. Each cruiser is larger and more complex than a fully-kitted titan legion. These things are MASSIVE. In the BFG book there's a fluff story of a cruiser being built at a shipyard that orbits a primitive world. The entire population of the planet were given over to mining the resources needed to build one single cruiser. It took them eleven years to mine the ore. Sure, that's a primitive world, but if you think about it that makes carving out the rocks for it the largest single project ever engaged upon without mechanization. If you add together all seven wonders of the world you aren't even close to the pile of rock we're talking about. So these things are a big fucking investment and the high lords really don't like risking them without a really good reason (<s>makes you questioning why they wouldn't build 20 smaller ships instead</s> ship sizes don’t work that way; 20 smaller ships against something capable of killing fifty ships that size is stupid so you build the one large ship so it lasts long enough to be a real threat, that said sacrificing escort and cruiser construction to a slightly smaller number to produce more raiders and destroyers to hunt enemy raiders and target vulnerable enemy populations would be a good idea).

So if you ever wondered why the Navy doesn't get more action, now you know. By the time the big, awesome ships get on the scene the invasion already probably finished and the bad guys moved on. Then you nuke the shit out of them from orbit or drop millions of poor bastards into the meat grinder. Far better idea all round. It's the reason that the enemy, even nutters like Chaos, don't fight in the void without reason. On the ground it's just a scrap, and maybe you win or maybe you don't. If you lose in the void then your campaign on the surface is dead. No reinforcements, no support and a massive constant orbital bombardment to kill everyone left (which sometimes doesn't happen, because, you know, <s>plot armour</s> shields, enemy surface-to-space weapons, don’t want to destroy your own territory when you can send mooks to reclaim it, etc.). That tends to mean fleets hover around and not fighting, one ensuring the other can't directly interfere with the surface war. This is actually an excellent and realistic explanation for why there is significant ground warfare in 40k. Also, ground-based defenses, mobile theater-shields, etc. are common. So, attacking a planet worth anything is like attacking a planet-sized Death Star without the super-weapon. Your ground forces taking out shields and anti-space batteries is critical to achieving anything. But, by that point, most of the enemy is dead and the survivors have either moved to the next defended region or got so stuck-in with your dudes that you can't shoot without killing your own army. Unless you worship Khorne, in which case you really couldn't care less who you kill, even yourself.

So, the navies of the galaxy ultimately get pushed down into either raiders, escorts against raiders, raider-hunters, or babysitting and logistical duty for groundpounders. Which of course brings back the question of why the Navy has such a desire to get more interceptors and bombers for ship-to-ship combat when they rarely engage in combat in the first place and the attack craft are insufficient. Could be to weaken the enemy ships' ability to shoot at the surface, but by the point they would have a target it would have (as stated) gone to a new defended location or whatever else, defeating the point of sending attack craft to weaken the enemy ships' offensive power. They won't shoot at each other, and they can't shoot at the surface (or at least can't shoot anything worth shooting at). In exchange for packing in so many attack craft into hangars designed for countless atmospheric air support fighters and bombers, the Imperial Guard has to die in radically greater numbers than they have any need to since they have limited anti-air capabilities and all of their enemies have no problem sending massive swarms of fighters and bombers at them. That is without even getting to engage the enemy on the ground and not counting the countless soldiers killed as the transports are shot to pieces due to their escorts commonly ditching them to go after obvious bait tactics. Against orders, by the way. Not that they’re ever disciplined for it. Attack craft would be useful for hunting raiders and defending convoys and transports. Maybe that is the Navy’s thinking: “If I had more Furies and Starhawks, I could send them to de-fang attackers of the troop transports and keep the ships that would have been escorting them.”

Thus the rumor that the Navy has no balls. But who needs balls when you have a nova cannon sized dick and eighteen dice worth of fire power.

===Ship Size===
No one is quite sure how big the ships really are. One story claims the Retribution-Class is a mere 3 kilometers long, while another says it is 9 kilometers and up to 20 kilometers.

Your best bet is Rogue Trader, although going by those figures, anything bigger than a cruiser has an average density around that of hydrogen... From a helpful poster on [http://www.heresy-online.net/forums/showthread.php?t=63267&page=2 Heresy-Online] we have this:

For the most accurate scale, look towards the Battlefleet Koronus Expansion, as it is more a stat/rule book than a story. That and previous consensi, as well as cross referencing with the Horus Heresy rulebooks by Forge World (which places Battleships at 8-12km) place Cruisers just above 5 kms, and Battleships in the mid 8s. Please note that most ships above the size of 8ish kilometers are either a unique modified/purpose built flagship or a ship of a small class that is not in widespread calculations. For a sense of scale the largest warship in the world is currently the US Navy's Ford Class Aircraft Carrier measuring in at 337 meters long or 0.337km making the USS Ford the size of a cannon. They have guns literally the length of an Aircraft carrier!

Ultimately, direct numbers are likely useless. The lance turrets have been described as the size of cities and given the size of an Imperial or even a modern city...also, there are about 75 ships in a Sector Fleet. A sector is one thousand cubic lightyears and there are about a thousand sectors in the Imperium. Which means logically those ships should be incredibly massive and easily ten or even a hundred times larger than the size numbers given in fluff given the size and industrial might and manpower of the Imperium.

*Transports and other Attack Craft, typically rated for atmospheric operation; also includes ships designed to be boarding torpedoes.
**<1 kilometer. That's the small ones, there are super transports in 40k as well. (A [[thunderhawk]] would go here).
*Escorts are "small" ships, like the Cobra, designed to flank foes and operate in squads.
**1-2 kilometers.
**Heavy Frigates
**Frigates
**Corvettes
**Destroyers
**Freighters
*Light Cruiser, a smaller Cruiser.
**3-5 kilometers.
*Cruiser, the standard fighting vessel; every Imperial fleet has them.
**5-6 Kilometers.
*Battle Cruiser, a beefed up Cruiser; generally more 'modern' than a Grand Cruiser.
**6-7 kilometers.
*Grand Cruiser; pocket-sized Battleship, very old.
**7-8 kilometers.
*Battleship; the biggest of the lot, simply put.
**8-12 kilometers.
**Battleships
**Fleet Carriers

The Horus Heresy novel "Know No Fear" had this to say about ship sizes, taken from [http://archive.foolz.us/tg/thread/22848349/ /tg/] who quoted it from the book and written here is just the lengths and names of the ships, for simplicity and space:

*Macragge’s Honour. Twenty-six kilometers - Flagship
*Spirit of Konor. Seventeen kilometers - Battleship
*Antrodamicus. Twelve kilometers - Grand Cruiser
*Antipathy. Nine kilometers - Cruiser (note that the book said it had "six thousand lives" on board, which would be an absurdly small crew for its size by 40k or even 21st century standards - Cruisers normally have 85-95 thousand crew in 40k, and that's for normal sized ones, not double length ones like this one. But this is a Horus Heresy ship, so perhaps it's automation was much better then a later 40k ship)
*Aegis of Occluda. Seven kilometers - Class unknown
*Gladius. Four kilometers - Escort
*Then there is the Abyss-class created by Lorgar that is said to match the Phalanx in size. He made three of them.

===Weapon Effects===
If the weapons can annihilate a continent, why can't it destroy a mere hive? Because different writers don't talk to each other that's why. Also shields maybe.

Alternate take: Sure these weapons can destroy continents, but generally speaking why would the Imperial Navy want to bombard a probably Imperial Hive? Another thing to consider is that while Imperial warships are capable of *BLAM*-ing a planet, it requires a lot of ships firing either specialized planet-killing ordnance or just bombarding round the clock. One virus bomb/Cyclonic torpedo/lance shot would do comparatively little damage. But it does make you think about how powerful those void shields must be.

Another take: Something to keep in mind is the different size of ships and thus cannon barrels. A Retribution-class battleship is a lot bigger than a Mars-class battlecruiser is a lot bigger than a Turbulent-class heavy frigate, just to name a few. Different ships have different weapons.

Another Alternate take : The heresy novels elaborate a little on little on the practicalities of Orbital bombardment as a battlefield weapon. Whilst it is occasionally used tactically and reserved as a strategic level weapon, it requires utterly pinpoint accuracy (targeting being off by a millimetre in orbit could result in a shot being kilometres off on the ground) which is only possible when orbit is completely uncontested. It's use during land battles is the VERY definition of Danger Close and often a dead giveaway to the enemy, as allied forces have to withdraw kilometres away before ordering a bombardment, letting an enemy force bunker down or get out the way. Ships are also very easy targets for anti-orbital weapons during bombardment and the effect of a starship hulk hitting a planet you're fighting for is not something to be risked.

Alternate alternate take of an alternate take take: Hives are designed to withstand bombardment from orbit while firing back with enough power to make enemy ships stay away. This is the main reason why massive ground engagements happen (and there are theater shields available, too). For example, the Rock of the Dark Angels survive Caliban being essentially turned into its component atoms via mass bombardment. Also, the previuos "Another Alternate take" directly above this one is right. Now combine that take with this one and really the only way to take an enemy position is to get off your ass and do it yourself the manly way.

Alternated take because alternate takes on alternate takes don't take what it takes: most weapons are jackshit useless against a planet with atmosphere and magnetosphere. Nova cannon shots, plasma bursts and lance batteries are distorted by magnetic fields, macrobattery shots burn up in dense atmosphere, just like torpedoes and most void-faring attack craft.
To fire effectively the ships either have to come CLOSER into low orbit (being exposed to oversized cannons and missile launchers that can be seen around every major spaceport and hive city) and risk being burst open like a pinata, or are forced to just shit bombs from high orbit, being absolutely horrible at aiming.

To the immediate above alternate take: No. Energy dispersal by atmosphere and magnetosphere does not work that way. If it did, we wouldn’t be able to have shuttles in real life. And the effects of atmosphere on lasers is meaningless above a small threshold 40k easily breaks many times over. Same for plasma and atmosphere and magnetosphere. The atmosphere and magnetosphere have no influence on orbital bombardment whatsoever. The shots are too powerful for the planetary environment to matter and it is ridiculous in the extreme to think kinetic rounds used by the Imperial Navy would be vulnerable to being destroyed by mere air friction. An atmosphere is not some sort of adaptive shield that destroys stuff more the faster the stuff goes. Air only heats up to a certain point and then either stops heating further or the air is what is destroyed instead as it breaks apart due to its energy imparted by friction. It isn’t difficult for modern science to build heat-resistant materials capable of this. Expensive in the modern day, but that’s about it. The magnetosphere likewise is not a magic shield of perfect defense. It has only minute effects on lasers, plasma, etc. which is why we have lasers, GPS, etc. and the magnetosphere’s effects are easily overwhelmed to the point of being negated. The atmosphere would actually have more of an effect on lasers and plasma, but the high energy is easily enough to overpower and negate such effects. In the worse case scenario, shooting a planet with a frigate’s laser weapons batteries causes the atmosphere below the shots to turn into basically a plasma shotgun. Same for plasma weapons but probably a fusion shotgun. Wait, why doesn’t the Imperium so that? Oh, right, [[Derp|intelligence is heresy.]]

===Lack of Balls===
It is well-known that most Imperial Navy Officers don't have em.

An Imperial Navy fleet is most effective when Inquisitors take it over. [[Exterminatus|See Here]].

===Carrier Hate===

Back in M36, the Imperial Navy fought a lowkey civil war over fleet doctrine in Segmentum Tempestus known as the Gareox Incident. A cabal of chaos worshipers worked their way high enough in the navy to start designing ships that were ready-built to turn traitor, most of which were carriers. The battlefleet eventually figured out something was off and the result was a giant carriers vs battleships fight that went down the way the Battle off Samar would have if the Japs hadn't been scared shitless by three destroyers. The surviving carriers went openly traitor and since then building new carriers has been borderline heresy so far as the navy is concerned. They don’t hate carriers, but many Imperial ships are basically battlestars, making carriers a pointless waste of resources. Attack craft are mostly used to weaken enemy firepower, shoot down torpedoes and enemy fighters and bombers and boarders, and finish off crippled enemy ships. On their own, they’re largely useless for actually defeating enemy ships. The main reason aircraft are so effective against navies in WW2 and modern navies is that they can use momentum for bombs and missiles to strike hard from above in order to penetrate decks. Space has no such option and every attack from any angle is similar to a torpedo plane attack run from the Second World War. Which is why Starhawk Bombers are basically just torpedoes. However, carriers are useful and accepted, just not useful enough to bother building from scratch and so carriers are almost always either repurposed wrecks of other ships or mothballed carriers being deployed where more attack craft are needed. This almost pointlessness also means carriers are looked down on as barely worth calling support ships.

==Music of the Imperial Navy==
Not to be outdone by the Imperial Guard (as well as to compensate for their aforementioned lack of balls), the Imperial Navy has begun collecting music to either be blared on loudspeakers when not in active use, or in the case of battleship command decks, played live by orchestra. the first four are taken from [[Battlefleet Gothic Armada|Battlefleet Gothic Armada.]]

[[File:imperialnavy1.jpg|400px|thumb||Cathedrals IN SPEHSS!]]

{{Topquote|When you began, you couldn’t have possessed enough bones for the whole ship. It would look stupid with a few dozen skeletons nailed to the walls. So, how do you start? Do you save up enough bodies for a corridor at a time, or put them away until you have enough to decorate the entire vessel?’|Jain Zar,-Storm of Silence}}

{{Topquote|By my faith, may the light of the Emperor spread to the farthest star. By my duty, the galaxy will belong to the righteous. By my actions, the Imperial Navy shall be honoured and remembered on Holy Terra. For the Emperor of Mankind, AND FOR THE BATTLEFLEET GOTHIC!|Imperial Navy Captain Abridal, shorty before his blaze of glory that ultimately stopped the 12th Black Crusade and saved billions of Imperial lives.}}

The '''Imperial Navy''' is one of the main branches of the [[Imperium of Man|Imperial]] military in [[Warhammer 40,000]] (although very little of the Navy actually appears in the tabletop game). They are also one of the main factions in the beloved spin-off game [[Battlefleet Gothic]].

Unlike the [[Imperial Guard]], who get killed in the <s>thousands</s> <s>millions</s> billions every day, the Imperial Navy rarely suffers that many casualties. This is because, unlike the [[lasgun|flashlight]] used by Guardsmen, the main weapon of the Navy is a giant, heavily-armed, heavily-armored battleship that puts other races' spaceships to shame (well, except [[Necrons]]). These ships are also [[Awesome|massive, flying, Gothic cathedrals]].

Depending on how you look at it (and who you're looking at), the officers of the Navy are either wealthy cowards or badass gentlemen. In either case, their ships have crews numbering the hundreds of thousands or even millions (we're not kidding when we say that each ship has its own language(s) and culture(s)), since the Imperial Navy doesn't understand how auto-loaders work, so loading a gun requires thousands of slaves running on treadmills. Of course, this might be the fault of [[Adeptus Mechanicus|a certain other branch of the Imperium, who, coincidentally, ''do'' have working auto-loaders on their ships]]. In any case, [[Grimdark|the Imperium has found it cheaper and ''more effective'' to use manpower because they have ''that many people'' to throw at even the tiniest of problems.]] Except that the cost of hundreds of thousands or even millions of chain-gangs adds up over centuries and millennia whereas maintenance for the machinery would basically amount to "apply oil while chanting". Of course, for a major officer, most days simply require him to press a button and blow something up, then go back to drinking his tea. Oh, and ''maybe'' scramble the ground-support flyers, if he's feeling charitable that day.

Note that, back in the [[Great Crusade]], the Imperial Guard and Imperial Navy were one and the same, operating under the far-less-badass name of "Imperial Army." However, thanks to the [[Horus Heresy]], the two got split up, so that a single military commander couldn't control too many forces; a Guard commander isn't able to get off any given planet without the Navy, and the Navy isn't able to conduct wars (and, you know, occupy territory) without the Guard. You'd think that this enforced mutual co-dependence would make them collaborate, but [[grimdark|of course]], despite how much they need each other, the two bicker constantly, which, in fact, may be the reason for all the [[fail|stupidity]] the 40k universe is saddled with, at least on the military front.

==Types of Ships==
The Imperial Navy has four types of ships they hide their cowardly asses in. The main ships are battleships, cruisers, escorts, and fighters
Each ship can also be classified by its weaponry, and role in the battlefleet:
*'''Basic:''' Jack of All Trades ships, due to having multiples weapons types, and not being specialized into any. Lunar class cruisers are the prime example, having macrobateries, lances & torpedoes.
*'''Lance-boats:''' Ships that focus into Lance weaponry, used for long-range focused attacks, especially against small ships & unshielded ones. Rarer as they have a weakness to Void Shields and require better drives due to the power requirements of the lances.
*'''Ordnance-boat:''' Opposite of the Lance-boat, replaces Lances with more Macrobatteries, focusing mostly into medium & short range brawls against enemy ships. Usually this is because they need extra power due to mounting a Nova Cannon or having power-hungry macrobatteries such as Plasma Cannons.
*'''Carrier:''' The red-haired stepchild of the Navy. Replaces the Lances with Launch Bays and is disliked by most Admirals due to the stigma against Attack Craft, although it is because the Traitors & Chaos pawns focused on raiding & striking fast, so with enemy fleets focused on long range attack (Lances, laser, and attack craft)plus Chaos likes them more because they can fill the bays with Assault Boats, the Imperial Navy might have got that stigma of seeing too many Chaos carriers raiding & pillaging imperial planets & so started dislike them. Some Carriers are also made from wrecked cruisers of other types, in which case damaged broadside weapons are ripped out and replaced by launch bays.
*'''Torpedo-boat:''' Originally an experiment for escort ships to overrun enemy vessel crews using boarding torpedoes, it was doomed to failure as the targets were either too nimble or too big. The Imperial Navy kept a few as Missile Destroyers.

===[[Imperial Navy Battleship|Battleship]]===
Supposedly rare, but every Grand Marshal and High Admiral has at least one and often several or even dozens to hide in because GW is completely and hopelessly inconsistent with fleet sizes, though as of late it seems that GW is leaning towards big fleets and big armies when it gives numbers. Bonus points if that coward is also Chaos. The biggest heaviest hitters available, these things are like actual medieval cathedrals in that the grandchildren of the workers who start building them get to live to see their completion. Fuckheug, lots (and lots, and lots) of guns and most can deploy fighters and bombers.
*'''Ordnance-boats:'''
**'''Retribution:''' Packing all gun batteries, the ship can devastate an entire continent in one broadside, but for some reason cannot destroy a hive city or fort with [[void shields]] - [[What|or in some cases, ones without any shields at all]]; either that or GW was just pulling another [[Derp|Michael Bay]] out of their asses again since, they have no idea how [[Herp|consistency works, let alone basic physics.]] Of course, considering the Dark Angels fortress-monastery and the huge chunk of land surrounding it survived the bombardment which turned Caliban into a bunch of space dust, it is perfectly reasonable that something that merely glasses half a continent would not destroy a void shielded city or other major fortification. If anything, this provides a degree of insight into why land battles in 40k are so massive in the first place. Because orbital artillery doesn't have many targets of opportunity it is actually capable of exploiting without tearing the planet to pieces.
**'''Invincible:''' An interesting class, dubbed a 'fast battleship', these were designed to chase down xenos and chaos raiders, and then use them to make the vast, empty tracts of space more interesting by filling it with their enemies' debris fields. This type of battleship combines the firepower of a ''Retribution'' with the speed of a ''Dauntless''. The problem with this is the general incompetence of Imperial tacticians. It looks exactly like a ''Retribution'' and has the guns to match, so it must be one, right? NO. They excelled at the role they were designed for, but throw them into gunfights against dedicated battleships, and these things tended to come apart easier than wet cardboard, earning them the nickname 'Kisher's Kombustibles' and the scorn of many admirals. Admirals who ignored the fact that the reports detailing the introduction of the ship and how to best use it (it's tactics also included in the Tactica Imperialis) explicitly state not to use it on a gun-line and that it is for fast-ship interdiction. The ship's Commissars must be particularly incompetent to let this slide as in the Guard the generals would be executed quickly for such incompetence. Of course, these are also the Commissars who do nothing when troop transports' escorts frequently run off to fight while the transports lose a significant percentage of their ships. Perhaps if they would actually enforce their orders to stay with the transports, the Imperium would have won most of the campaigns it has lost. Given that they still often win even with a fraction of their beginning ground forces actually managing to make landfall. [[Grimdark|Because they have THAT many men to throw at the enemy.]]
***Much like the Chalice-class of Battlecruisers, the Invincibles are a big reference to the real life Battlecruisers of World War 1, especially with the term "Kisher's Kombustibles" (real life Battlecruisers were referred to as "Fisher's Combustibles") and the fact that three blew up in a single battle (referencing Jutland).
*'''Lance-boat:'''
**'''Apocalypse:''' One of the oldest ship designs (predating the ''Retribution'', which is also one of the oldest ship designs), this ship packs a lot of [[lances]] and a [[Nova Cannon]]. Good for taking out lots of smaller sized ships with massed lance fire. It's also described in fluff as being able to cripple anything up to a cruiser with a single, concentrated broadside. They're fairly rare, since the Imperium doesn't know how to build them anymore, and the ones still operating are so old, their weapons systems have degraded permanently, forcing them to fire their lances at only a fraction of their full power. Shares all the disadvantages of a ''Gothic''-class cruiser.
***Despite the fluff stating that the Apocalypse and Oberon classes are unique in that they lack figure-heads, the artwork and [[Crunch|models]] [[Derp|give them one anyway.]]
**'''Victory:''' Possibly an attempt to recreate the ''Apocalypse'' class, the ''Victory'' is basically a ''Retribution'' with a bunch of lances replacing its broadside cannons, and a Nova Cannon instead of torpedoes. Has the range that fluff states the ''Apocalypses'' once had, but lacks the same level of firepower. Effective at sniping, and hilarious when used against escort heavy fleets.
**'''Desolator:''' A ridiculously old design. Designed to emphasize range and carries Torpedos, Broadside Lances and Dorsal Macrobatteries. Like most keel-built ships, the Desolators ended up mothballed or went traitor.
*'''Carrier:'''
**'''Emperor:''' The "standard" battleship of the 40k 'verse, the ship has multiple fighter decks and weapons batteries. Unfortunately, most commanders like to use this ship as a hideout, causing the lack of sufficient air support in the ground wars even though the Navy's atmospheric aircraft are completely different from its much bigger space based strike craft. Tabletop-wise, its status as the official battleship of Battlefleet Gothic doesn't stop it from losing carrier duels against the Chaos equivalent.
***Ironically, the idea of the Emperor being the standard battleship conflicts with the fluff about the Navy hating Carriers. Go figure. Except it doesnt. Because the Imperial Navy isnt fond of carrier ships, but that doesnt mean they dont use them; So if you were an imperial admiral, would you choose to get multiple smaller carriers, at the cost of having less ship-of-the-line on your fleet? Or would you instead get a 8+ kilometer battleship with four city-sized hangar bays, having higher detection, and being capable of helping your fleet & any warzone in multiple ways (Not just void warfare, but also ground support in planet invasions, or logistical support) without the need of going too close to the enemy? Its no wonder the Emperor Class is so popular & useful in the Imperial Navy, looking at this way, in reality, the Emperor class goes well precisely on the conventional Imperial doctrine because of this reason. Despite the (idiotic) distaste Admirals have for strike craft, they will use still use them out of simple utility and they figure they might as well get something that can do more at the same time.
**'''Nemesis:''' The super-carrier of the Imperial Navy. It has SIX flight decks (the size of towns or small cities, each), more than any other ship in the galaxy. But because of Rule of Cool, it is incredibly rare since the Navy captains prefer to get up close broadside their enemies, or actually rather because all of the ships in this class were just ships modified from Emperor class ships in one particular war, because they were damaged or otherwise. Naturally, the Navy never considers making them based on the Invincible instead (the Invincible was mass-produced).
**'''Desecrator:''' The carrier variant of the Desolator. Replaces half the Broadside Lances with Landing Bays. Shared the same fate as its sister class and is now only seen in Chaos fleets. Traitorous despite its clearly pious and Emperor-loving name.
**'''Despoiler:''' Oh boy, where do we start? The Despoiler-class came about after the cogboys discovered plans for a carrier on Barbarus. The catch? Well, Barbarus is the former homeworld of the [[Death Guard]], and the plans were for the same class of ship that the [[Terminus Est]] is a part of. Showing a complete lack of common sense, the Imperial Navy decided to build ships of this class, only for them all to go traitor due to the class's inherent [[Gellar Field]] flaws. [[Fail|Oops]]. The Despoilers at first don't appear to be that unique, as they have Dorsal Lances and Broadside Landing Bays and Weapons Batteries. Their difference is that, like the Terminus Est, they managed to have a Prow Landing Bay as well.
***Despite being a new class, GW fucked up their fluff and had [[Rogal Dorn]] disappear aboard a Despoiler, [[What|5000 years before the class was created]]. Note this class was actually already named "Despoiler-class" by the Imperium. Yet, they were ''surprised'' the things went traitor. Wow. Also, after fixing the Gellar Field problem, the Imperium still decided not to build more, which was stupid since there was no longer a reason not to. I get not wanting to chance it, but beggars can't be choosers.
*'''Other:'''
**'''[[Gloriana-class_Battleship|Gloriana]]:''' Massive, terrifying and capable of decimating entire fleets on their own, these were the personal flagships of the Primarchs during the Great Crusade. Very few, if any, are still around in the Imperium in M41, though a few such as Horus's flagship ''[[Vengeful Spirit]]'' are still tooling around inside the Eye of Terror. Because they were dickheads, the [[Alpha Legion]] had two, creatively named the ''Alpha'' and the ''Beta''. Interestingly, the Ultramarines have one, the ''[[Macragge's Honour]]'', but didn't [[derp|fucking]] use it, the whole fucking time until [[Roboute Guilliman]] returned. It shows up again in ''Dark Imperium,'' with the Smurfs having stolen it back from the Red Corsairs, which at least is fucking funny even if it makes no sense. The Imperial Fist had the ''Eternal Crusader'', but it was never their flagship since the [[Phalanx]] is so much better, so [[Rogal Dorn]] gave it to the [[Black Templars]] in the [[Second Founding]]. The Emperor is known to have had at least one, called the ''Bucephalus'' (also the name of the horse of Alexander the Great... coincidence?), which he ditched after upgrading to an enormous golden space palace called ''Imperator Somnium'' for the sole purpose of flying him back to Terra to retire. Wait, did Emps just see the Phalanx and decide to build his own bigger better version?! [[Eldrad|DICK]].
**'''Oberon:''' The mixed-breed bastard of the Imperial Navy. It has [[lances]], fighter bays, and weapon batteries. Its a powerful ship... <s>when fighting foes half its size</s> "Newer" fluff says the Oberon is rare, but a complete success in making a ship capable of killing anything it comes across, alone. Unfortunately, fluff also says a ridiculously low number of these (apparently) powerful ships were made (like, 3 or so). Then again: only four Iowa class battleships ships were built (technically 6, but 2 were scrapped before completion), and we know HOW to build them. It makes sense in a way. Attack craft can cripple an enemy's main weapons and engines and likely ultimately damage the power transfer from generators to void shields. Combined with macro-batteries hammering away and the enemy's weakened ability to maintain its shields would cause them to drop much quicker than usual. Then the city-sized lance-batteries rip the enemy in half. If used against enemy escorts to support attacks on large enemy ships like battleships and grandcruisers, this would work extremely well to the point an Oberon would likely become a priority target for enemy ships.

===[[Imperial Navy Grand Cruiser|Grand Cruiser]]===
Only slightly weaker and less powerful than Battleships, Grand Cruisers were the weird middle-child of actual Line Ships (that really were the mainstay of the fleet back then) and Cruisers in the ancient Imperium. Built primarily with autonomy in mind, those were reserved for the most daring expeditions in the uncharted regions, conducted both by Imperial Army and Rogue Traders. Nowadays most of them run on archeotech that is barely understood and hard to repair with current Imperial knowledge. These grand ships are often used as flagships in lieu of extremely rare Battleships. Basically, they are the quintessential Battlecruisers; tougher and deadlier than Cruisers and yet more mobile than Battleships.
*'''Basic'''
**'''Vengeance/Furious:''' The granddaddy of "modern" Imperial warships. The ''Vengeance'' was the winner of a GW-sponsored ship design contest, and was originally known as the ''Furious''. Highlights include heavy shielding and armour (though lacking the prow armour of later designs), as well as both lances and long range weapons batteries, making this the sniper of the Imperium's Grand Cruisers.
**'''Repulsive:''' Originally named the Corinus Class, before being renamed after many fell to Chaos by an overly literal Mechanicum designation. Whilst the Repulsive Grand Cruisers are exceedingly maneuverable heavy warships (and therefore exceedingly useful because they can fill a hole in the Imperial tactical lineup), they are considered a cursed class due to the majority of them falling to chaos, [[Fail|which unfortunately was the result of experimental warp drives which occasionally interfered with the Gellar Field (OMGWTFBBQTIME)]]. Only the Emperor knows what kind of complete moron would deploy ships equipped with that. The ones that remain in Imperial control are kept mothballed in reserve fleets and segmentum fortresses (imagine giant glass boxes with 'In Case of Emergency, Break Glass' signs). It doesn't say anything about their warp drives being swapped out for something that isn't shitty or perhaps a completed and no longer experimental version of their own. Not that you want AdMechs tear off your head for tinkering with their sacred templates, on the other hand.
*'''Ordnance-boat:'''
**'''Avenger:''' The short range brawler of the Imperium's Grand Cruisers, it's a ''Vengeance'' with only macrobatteries (kilometres of Macrobattery broadsides). Intended to break the line of battle like Nelson's ships at Trafalgar, while suffering from the lack of an armored prow. Unfortunately line-breaking is quite a dangerous role for any ship, even a Grand Cruiser that excels at doing it, and so not many exist in the 41st Millennium. Those that have survived are known for being exceedingly reliable and faithful; it takes a lot of damage or mistreatment to cause these noble vessels to give trouble. If you spoke with members of the Imperium (both members of the public and the navy), this is the vessel they would think of if you asked them about Grand Cruisers. Now, if only the Imperium realized a slower but more heavily armored and shielded ship would fare better in its role.
*'''Lance-boat:'''
**'''Executor:''' The sniper of the Vengeances, the Executor replaces its Broadside Macrobatteries with even more Lances. Unfortunately, the last remaining Imperial Executors decided to act retarded and chase a fleet into the Eye of Terror, meaning that all of the ships are chaos aligned now.
*'''Carrier:'''
**'''Exorcist:''' A ''Vengeance'' that has carrier bays in place of lances. Useful in providing carrier support to any Imperial fleet. As a bonus, being Grand Cuisers mean they can outrun anything except battleships to save their vulnerable carrier self while their attack craft are away. Originally designed for extended operations alone on the Frontiers of Imperial Space, either on Patrol or by exploring into the unknown, the Exorcist developed quite a reputation for 'boldly going where no man has gone before'. Whilst not many remain in Imperial Service due to maintenance difficulties, they still find use in the hands of Rogue Traders who need vessels capable of long cruises and of defending themselves against anything they might encounter. So much for maintenance difficulties.
**'''Retaliator:''' A mix of a Repulsive and a Vengeance, but as a Carrier. Has Lances, Launch Bays and Macrobatteries on its Broadsides. Unfortunately, it has the Repulsive's tendency to go traitor.

===[[Imperial Navy Battlecruiser|Battlecruiser]]===
What do you do when you forget how to maintain an entire category of heavy warships? You build a new bunch of heavy warships, with simpler technology.

Battlecruisers are basically upgunned cruisers, with more weapons (usually adding dorsal weapons and some armor), and are intended to fill the gap between true battleships, which are rare, and normal cruisers, which tend to die really easily to the ancient Chaos cruisers and grand cruisers. Battle cruisers were tried in real life as some way to combine battleship firepower or armor and cruiser speed. They did not always work, and much like reality these things have their share of problems. Chaos operates their own versions known as Heavy Cruisers. In real life, the accepted successful form of a battlecruiser is between a heavy cruiser and a battleship; it can kill anything it can catch and it can outrun anything that can kill it (usually only an enemy battleship). After its teething years it was generally a good and effective form of combat when used intelligently.
*'''Basic:'''
**'''Armageddon Battlecruiser:''' An upgraded variant of the Lunar Class Cruiser (YAY! ANOTHER ONE!). A rather new innovation, the Armageddon class is basically made up from recovered Lunar Class Hulks that have been extensively repaired and then retrofitted with more armour and more weapons. The base hull was never designed to cope with all this extra equipment (and the extra crew to man said equipment) and so it has problems operating independently for long periods of time. This isn’t really a problem, though, since they wouldn’t be operating away from a fleet anyway. Though reinforcing its frame to handle the added mass would be a smart thing to do to save immensely in future maintenace costs over the centuries. Battlefleets won't say no to them because more guns = better! These ships are extremely powerful and live up to their name. Somehow, though, the Imperium never went “Hey guys, this thing kicks the shit out of everyone, let’s upgrade all Lunar-class ships to Armageddon-class and make a new class to accomodate the new crew and equipment.” Or someone did and was turned into a servitor...
**'''Hellfire Heavy Cruiser:''' An upgunned Murder-class. Has the same issues as the Armageddon, slow as fuck and has power and supply issues. [[What|Also, lacks Void Shields]]. Most mutinied and joined Chaos, which decided to use them for some reason.
*'''Ordnance-boat:'''
**'''Overlord Battlecruiser:''' The Classic Imperial Battlecruiser. Using the standard Imperial doctrine of - Macrobatteries, Lances and Torpedoes, the Overlord has become the most effective Battlecruiser simply because it really complements standard Imperial Navy Tactics. As an added bonus, its simplicity of design makes it easier to produce and one can be built within a decade. The only negative (if you can call it a negative), is that it's not really useful for anything except war.
**'''Chalice Battlecruiser:''' A fast heavy cruiser. Unique to the Calixis sector and an exceedingly new design, the Chalice was conceived as a Battlecruiser that could either out-run or out-manoeuvre anything it can't kill. Which means it was conceived to be a plain ‘ol normal battlecruiser. Whilst good in theory, unfortunately, speed came at the cost of armour and durability and so whilst these vessels punch hard, they can't take as many hits as other cruisers. In addition, it carries an experimental plasma drive layout, which while boosting power efficiency, also makes it rather vulnerable to lighting up like a roman candle. Imperial Propaganda is currently trying to cover up their failings and is lauding them as the Poster-ships of the Calixis Sector and therefore a lot of people think they're the 'Best Battlecruisers Eva!'. If they would just use a normal plasma drive and make the whole ship bigger, it would be fast enough, armored enough, and even better armed. Unfortunately, not being stupid is heresy in Calixis.
***The idea of a ship that can "either out-run or out-manoeuvre anything it can't kill" that turns out to be really poor at taking hits was the original design of real life Battlecruisers, which although being up-gunned Cruisers (which are the equivalent of Frigates IRL, not Ships of the Line), were used as discount Battleships at Jutland were they turned out to lack the armour required for a proper fight. Thus, if the Imperials were smart, they would be using the Chalice as a commerce raider, not a ship of the line.
**** Actually, they were not bad at taking hits, they were better at it than heavy cruisers. They just sucked at taking hits from battleships like everybody else on the planet. Real life battlecruisers (after their early screw up designs) were made only a little smaller than battleships which allowed them to have greater armor and firepower and speed than heavy cruisers and were even fast enough to outrun battleships at the cost of significantly lower firepower and armor than the only slightly larger battleships (which caused things like the Jutland kablooie). They had the whole package. In reality, the larger the ship the faster it is in navies (broadly speaking, in dense fluids the longer the vehicle is relative to its cross-section, the easier it is to go fast), sci-fi just is made by ignorrants. Battlecruisers fell out of favor shortly after they were perfected for the same reason battleships and heavy cruisers did: the carrier. That said, they were indeed usually used as commerce raiders. But that is true for all ships. Navies exist to destroy enemy commerce shipping and to transport armies. The only reason fleets engage each other is because both sides defend their own shipping and seek out enemy fleets to pre-emptively destroy to protect said shipping and transports. In 40k, it could be said that the Invincible-class is the closest thing the Imperium has to an equivalent to a real life battlecruiser.
**'''Long Serpent Battlecruiser:''' A true success story, this is what the ''Chalice'' wishes it was. Taking a battlecruiser's armour and firepower, and giving it the engine suite of a battleship, this thing can kick the shit out of anything short of a grand cruiser or battleship, while being able to keep up with raiders. It's only real flaw is that when one is taken out, it has a better than average chance of rupturing its warp drive. As a result, the names of ''Long Serpents'' that have been destroyed are usually accompanied by those of allied ships that were too close. Which is somewhat odd since the reasoning is that the Long Serpent also has a battleship's warp core (who knows why, it isn't big enough to need it). Given the small difference in size between this ship and other "normal" cruisers which are the mainstays of the fleet, the Imperium could just choose to use a smaller warp core suitable for this ship's size and focus on mass-producing the Long Serpent to replace basically every other class of ship except battleships , Cobras, and carriers. Fewer would be made but, unlike video games, swarming a capital ship with escorts does not work at all. The escorts are slaughtered and the capital ship like this one is left unharmed. But doing this would require common sense, which is [[Heresy]]. Like properly using the Invincible-class must be.
**'''Mercury Battlecruiser:''' Another fast Battlecruiser. It's a cruiser with a Battleships's engines. Nothing more.
**'''Hades Heavy Cruiser:''' A long-ranged brawler. Carries Broadside Macrobatteries and Dorsal and Prow Lances. Got phased out like most keel-built designs, but Chaos still uses them.
*'''Lance-boats:'''
**'''Acheron Heavy Cruiser:''' Designed to test new Lances and Macrobatteries. The Imperials only built one, which went traitor. Carries Broadside and Dorsal Lances with Prow Macrobatteries.
*'''Carriers:'''
**'''Mars Battlecruiser:''' In a word - Mediocre. Some Imperials say it's versatile due to its diverse weapons loadout but in reality it makes it an awkward duckling to use. The Nova Cannon and Launch bays would be good on a ship holding back and harassing enemies at range and yet it has Macrobatteries and Lances which are great for brawling. So if you sit back and harass or go in and brawl, you're wasting half your ship. The Imperial Navy never really got on with it either and so it has gone out of production on most Forge-Worlds. Which is a shame because if they would replace the macrobatteries and lances with larger, long-range lances, and a great number of small, short range weapons batteries for fighter support and self-defense respectively, this would be a great ship in any fleet. It's nova cannon clears a hole in the enemy escort screen, the attack craft rush through to wreck the weapons and engines of light capital ships while long-range lances assist other Imperial ships in slaughtering targets of opportunity. The destroyed enemy light capital ships leaves all the other big ships vulnerable to mass, concentrated torpedo attack from friendly ships. Attack craft return to the fight to tear up the no-doubt seriously damaged enemy big ships and lances win the day. Then just send in friendly light capital ships with attack craft support to finish off the surviving escorts. That would almost make this ship into a sort of miniature "I Win" button. Almost. Especially in a squadron of two, as they could assist each other against any opponents that slip through to them with their combined, close-range firepower, lances, and whatever attack craft they kept back for defense ripping the enemy weapons and engines apart to let the close-range macrobatteries have fun.
**'''Dominion Battlecruiser:''' Basically a fixed Mars, some tech priest got it in their head that, maybe, it'd make more sense to replace the Macrobatteries with Lance Batteries instead, making it a dedicated support ship, harrassing enemy ships at range whilst the big guns go out and fight. Apparently not that successful, a number were used at the Battle for Maccrage (Of course the fucking Smurfs get them) against the tyranids, though apparently they all got fucked up and have been in drydock since, which is why up until now no-one's seen them.
**'''Styx Heavy Cruiser:''' A pure carrier. Has Broadside Launch Bays, Dorsal Lances and and Prow Macrobatteries. For some reason the Imperial phased it out for the Mars, so only Chaos uses them now.
**'''Hecate Heavy Cruiser:''' An attempt to replace the Styx. Swaps out some of the Launch Bays for Macrobatteries. Believed to have an inherent design flaw that made them go traitor, so they were decommissioned.

===[[Imperial Navy Cruiser|Cruiser]]===
Cruisers are the bread and butter of the Imperial Navy. Much larger than escorts and light cruisers, but less rare than battleships, cruisers are what the Imperial Navy (and Chaos and Xenos) use to fight their campaigns across the stars. Thus far, all Imperial Cruisers have been shown to utilize the same hull-type: a squat armored prow in front, capable of mounting a prow-mounted weapon system, and a big bunch of engines in the back, with baroque and Gothic architecture in-between. Most cruisers can effectively be placed in four categories:
*'''Basic:'''
**'''Lunar:''' The Lunar. You've heard so much about it and now you want to know what it makes it the standard Imperial Cruiser. First of all, it's one of the oldest designs still in use by the Imperium and is so easy to build that even less advanced worlds can produce them. They're quite versatile due to their weapons loadout (a balanced build of Macrobatteries, Lances and Torpedoes) and make up the backbone of Battlefleets throughout the entire Imperium. This is the cruiser against which all other cruisers are measured.
**'''Emasculator:''' Considered a failure by the Imperium at large, Emasculators have the same basic load-out as the Lunar, but are keel-built, lacking the armored prow and replacing the torpedo tubes with more weapons batteries. This means they require different tactics to a Lunar, using their speed and longer ranged weapons to pound ships from a distance. As this fits with Chaos tactics more than Imperials. most of them ended up as traitors. [[/d/|The name Emasculator is due to them being seen mostly as Slaaneshi ships, their original name is unknown.]] The fact the Imperium keeps trying new ships built on the normally Chaos style hulls implies that usually it must work out just fine since otherwise it would have been banned by now. So, there are probably many cool looking keel-based Imperial ship classes floating around we'll never catch wind of ever.
**'''Slaughter:''' A special type of Cruiser, the Slaughter-class has a more powerful drive called the Scartix Engine Coil, but lacks prow weapons. Armed with short ranged, but powerful lances and macrobatteries, the Slaughter is designed to get in close, blast away and retreat. Unfortunately, the Imperium can't build them anymore because one went traitor and destroyed the plans for the Scartix Coil. It is unknown if they were always called the Slaughter-class or were renamed when most went traitor. Considering the usual lack of intelligence in the Imperium's leadership, it was probably called something worse, like the "Traitor-class" or something and then the Imperium wss shocked when they lived up to it. Really, would you be surprised if the Imperium did that?
**'''Inferno:''' A earlier counterpart to the Carnage-class, carrying more lances in exchange for some Macrobatteries. Had the same difficulties as the Carnage and was mothballed, though a few went renegade beforehand. Rare example of the Imperium learning its lesson. Still too stupid to realize that using cheaper-after-a-few-centuries-than-manual-labor auto-loaders would've fixed the problem for both ships.
*'''Lance-boat:'''
**'''Gothic:''' Another variant of the Lunar Class, the Gothic is designed as a heavy Lance gunship. Due to the amount of Lance Weaponry it carries, it can easily deal with ships of its own size or larger but often does require an escort or a partner to strip enemy void shields first in order to use its own weaponry to the maximum effect. When supported and used correctly, Gothic Cruisers are the most efficient way to deal with enemy capital ships.
*'''Ordnance-boat:'''
**'''Dominator:''' A variant of the Lunar Class, the Dominator is designed primarily for planetary bombardment and assault. Not generally used in fleet actions even though it can provide support with its Nova Cannon when necessary. After one Dominator fucked over a Chaos Cruiser with said Nova Cannon during the Gothic War, the Navy took note and started making more Dominators. [[Awesome|Additionally, another Dominator came close to destroying the Terminus Est (''aka the toughest Battleship in the galaxy''), before being destroyed.]] The Dominator possesses the same armament as the Retribution-class battleship but lacks the range of one. This is fine, though, since it's meant to get close to the enemy like most Imperial ships anyway. Basically, if you get in range of this thing, ''you're going to die''.
*** From Lexicanum 40K: "Captain Straden of the Depth of Fury defended the shrine world of Kathur to the death, and came very close to destroying the Death Guard ship Terminus Est. As it was, he and his crew vaporised several of its decks and destroyed scores of escort ships before finally succumbing. Ironically, no Imperial souls survived to tell the tale."
**'''Tyrant:''' The Tyrant was originally intended as a stand-off vessel; it would stay at long range and bombard enemies from afar with superfired plasma weaponry. Unfortunately, due to design compromises where it mixed both short range and long range weaponry to save on power, it wasn't really deadly enough at long range to do its job. Therefore the Imperial Navy is trying to replace the short range weapons with ancient Long-range weaponry (that doesn't use a lot of power) recovered from Space Hulks or Renegade Ships. The Hull itself is a rather effective design and so the Tyrant has become very popular with Rogue Traders who generally replace all of the Plasma Weaponry in order to have more power available compared with other cruisers.
**'''Relentless/Carnage:''' Another attempt at a fleet support ship with Plasma weapons, the Relentless ended up with technical difficulties and, when these were overcome, [[Heresy|most ships ended up turning traitor]] [[Fail|(including the lead ship of the class)]]. [[Tzeentch|This is theorised to be due to something wrong with the geometry of the ship's design]], as the Relentless-class is keel built, like most older ships (This also means the Relentless lacks an armored prow and torpedo tubes, carrying more plasma batteries instead). The tendency of these ships to turn to Chaos, along with changing tactics, led to the class being renamed the Carnage-class and mothballed in favor of the Tyrant-class, though their speed means they suit Chaos tactics famously.
*'''Carrier:'''
**'''Dictator:''' A Carrier retrofit of extremely damaged Lunar Class Cruisers. If a Lunar class has its lance weaponry destroyed, it's quicker, easier and cheaper to replace those with heavy launch bays for strike craft. This makes it quite versatile and able to deal with virtually all situations and interestingly enough, makes it more effective than the original Lunar Class at everything except fighting as a ship of the line. Unfortunately, the Lunar Class is designed for fighting as a ship of the line, so Admirals dislike Dictators.
**'''Jupiter:''' A kitbashed design, converted from other classes of cruiser that have been heavily damaged in battle. By stripping out all the damaged components and replacing them with launch bays, you get a pretty sturdy carrier. Just don't let the enemy get anywhere near it. Apparently the Imperium doesn't build these normally at all, likely because they are absolutely shit at defending themselves from other Cruisers.
**'''Devastation:''' Deviating from the standard Carrier design, the Devastation-class carries Lances instead of Macrobatteries. Mostly turned traitor or mothballed, as they lack armored prows and torpedos; and are keel-built. Chaos likes them, as they can pack them with mutants and sit back to spam assault boats and lances at anything that looks at them funny.
*'''Other:''' Various other cruiser types exist, but are rarer.
**'''Ambition:''' Custom-made Cruisers for the exceedingly affluent - it's the Rolls Royce of the Cruiser World. Most Rogue Trader ships are second-hand, battle-scarred, tired and worn ex-navy vessels but the Ambition is not. It's the only cruiser class that can be bought brand spanking new by Private parties in the Imperium and each one is unique and built to the customer's specifications. These exclusive ships, whilst still cruisers and deadly in their own right, are stately homes and status symbols. Some durability sacrifices have been made in order to make them the most opulent and luxurious ships on the market but for eccentric people like Rogue Traders, it's generally worth it.
**'''Conquest-Class Star Galleon:''' Built for the very first Rogue Traders on the orders of the Emperor himself, the Star Galleon is an ancient and noble design. Whilst not considered heavily armed by modern standards, they're still formidable opponents and yet as specialist exploration vessels they are able to operate independently for many years and can transport greater quantities than other Cruisers. In effect, it's a cruiser fused with a transport and looks fucking amazing.
**'''Murder:''' The predecessor to the Lunar. Differs by being keel-built, exchanging their torpedos for Lances and having more powerful macrobatteries. The majority that appear in modern 40k are Chaos-aligned, as the Imperials mothballed theirs in favor of the Lunar. A few carried lances as well as Macrobatteries, meaning they don't fit into any category. As with the Slaughter, it is unknown if Murder-class is their original name or they were renamed.

===[[Imperial Navy Light Cruiser|Light Cruiser]]===
Smaller than true cruisers, light cruisers are used in two ways. Either you use a fast, maneuverable light cruiser like the Dauntless to add some extra firepower to a scouting squadron or long-range patrol, or you use a pocket cruiser like the Voss light cruisers to add some heavy firepower and armor to a convoy, fleet, or base. The advantage of the light cruisers are that they're cheaper to build and operate than real cruisers. Another departure from real nomenclature. In real life, “light” cruisers were less armed and armored normal cruisers made to make up for losses, especially in America after Japan’s initial attack. After the industry fully turned to wartime manufacturing, the light cruisers’ changes were recinded and they were just normal cruisers again. However, with the introduction of heavy cruisers, the normal cruisers again were named “light” cruisers to avoid confusion. In 40k, however, light cruisers are very distinct and fill a unique niche. Like the Cruiser, they fit into a few base categories.
*'''Basic:''' Same as its larger sibling, a Jack of All Trades.
**'''Dauntless;''' The standard Light Cruiser of the Imperium; it's a Jack-of-all-Trades. You can't go wrong with the Dauntless even though other Light Cruisers may be better for certain tasks. Considered 'scouting' cruisers, these make up the bulk of Imperial Patrol Squadron leaders.
**'''Defender:''' A convoy escort variant of the Dauntless, with added dorsal weaponry.
**'''Endeavour;''' A 'heavy', Light Cruiser, designed as a stop-gap between the 'lighter' light cruisers and true cruisers. Whilst they can slug it out in a fleet fight, they can easily be overwhelmed because they simply aren't cruisers and don't have the equivalent fire-power or hull integrity. As an added titbit, most of Battlefleet Koronus' patrols consist of an Endeavour and a pair of frigates.
**'''Lathe-class Monitor-Cruiser;''' An Adeptus Mechanicus Light Cruiser designed around deep space exploration and extreme self-reliance. These ships, when properly outfitted, can operate for decades without returning to imperial space for resupply. These would make up the bulk of Explorator fleets.
**'''Secutor-class Monitor-Cruiser;''' An Adeptus Mechanicus Light Cruiser designed to excel at the art of war. Tougher than all of the other Light Cruisers and yet still more mobile than true Cruisers. Due to being designed from the ground up to be a Warship, this Light Cruiser is fitted with Cruiser sized Void Shield Generators.
**'''Siluria;''' Three-quarters the cost of the Endeavor, and about three-quarters the ship. Standard weapon batteries only, no fancy frills to speak of. Cheap and effective, at short range, to catch enemy torpedoes.
*'''Lance-boat:''' Also the same as the Cruiser version, though some have weak weapons batteries for better defence.
**'''Endurance;''' Light Cruiser with just enough guns to claim it has them, lance batteries and a couple of torpedoes. It's the lance half of a Lunar, nothing more.
*'''Carrier:''' More useful as a Light Cruiser, as it can act as backup for patrols.
**'''Enforcer:''' A carrier variant of the Dauntless. Designed to maintain control of rebellious planets via intimidation [[Grimdark|(and possible orbital bombardment)]]. Given one managed to stop the rebellion of an ''entire sub-sector'', its a shame the Imperium doesn't build more of them.
**'''Defiant;''' A carrier variant of the Endeavour. It's quite versatile (by virtue of being a carrier) and so has found a home in many Rogue Trader houses but unfortunately the Imperial Navy doesn't consider it as useful because they can't stand by themselves and require an escort. Due to being based off of the Endeavour, it's relatively well armoured for a Light Cruiser and that does help with its survivability.

===Ironclad===
8 kilometer long battering rams. No, really. Tyranids and Orks are busy taking notes.

===[[Imperial Navy Escort|Escort ships]]===
Escorts are the smallest armed vessels available to the Imperial Navy. These ships are normally assigned sector patrol duties or perform as escorts for much larger ships. In fleet engagements they will also act as scouts, ranging out in front of their armada to verify enemy ship numbers and locations. They are generally clasiffied as either frigates, or as destroyer ships.

====Frigates====
Ranging from about 1.4-2km long. They are used for all sorts of duties from convoy escorts to attack or patrol squadrons. Ironically named, as in real life Frigates were the same as Cruisers (which were not Ships of the Line).
*'''Basic:''' Laser batteries only, maybe some Torpedoes if you're lucky. Named after types of swords.
**'''Sword Frigate:''' The most common warship in the Imperial Navy, and one of the simplest. No torpedoes or lances to distract you here; a Sword puts two massive laser batteries behind a pointed armored prow and cuts into enemy formations like [[C.S Goto|a multi-laser through canon.]]
**'''Falchion Frigate:''' A new (245 years old) class of escort ship built by [[Forgeworld|Voss Prime]]. Slow as balls but still capable of firing torpedoes. While Cobras are used offensively in fleet actions, Falchion's are designed to be convoy escorts and stick close to larger warships to defend them from enemy escorts. Effectively a Voss-pattern Sword with torpedo tubes and one laser battery.
**'''Claymore Corvette:''' Designed entirely around escorting vulnerable transports and protecting them against light raiders in order to allow true Frigates to accompany more valuable ships such as Battleships, Battlecruisers and Cruisers. The Claymore Corvettes are easy to mass produce and maintain and are exceedingly common in the private sector, as they are simply a discount Sword.
**'''Turbulent Heavy Frigate:''' Heavy Naval Escorts; these things have comparable armour to cruisers. They're built to sally forth ahead of the main fleet and win skirmishes against enemy scouting forces and vanguard elements. They've garnered a reputation for being lucky; they've contributed to many glorious victories and survived catastrophes that other ship classes have not. Their only downside is that they have rather antiquated communication equipment, probably equipped for durability, not ease of use.
*'''Lance-boat:''' Rarer for Frigates, as they need a Prow slot to mount a Lance.
**'''Firestorm Frigate:''' A Sword-class frigate with a prow-mounted Lance replacing one laser battery. Gives the Sword some extra anti-ship punch that it dearly needs. It's also two hundred meters longer than the Sword-class as a result. The Navy does not like the Marines having them, for some reason.
**'''Thunderbolt Heavy Frigate:''' Not much information on this one, but implied to be a Lance version of the Turbulent, like how the Firestorm is the Lance version of the Sword.
**<s>[[Derp|Given the general naming scheme for Frigate classes is naming them after weapons (Claymore, Sword, Falchion, Gladius etc), the Firestorm would make more sense being called the ''Lance''-class due to its role.]]</s> It's pretty clear refits do not follow the same naming conventions.
*'''Ordnance-boat:''' Mostly upgunned Frigates. Can carry a mix of macrobatteries and small lances.
**'''Tempest Strike Frigate:''' Specialized Brawling frigate designed for devastating enemies at close range. Basically a Sword with a triple armoured prow and heavy short-range broadside batteries. They're often equipped with Assault Boats and Barracks for boarding actions.
**'''Havoc Merchant Raider:''' Small, yet fast raider sized vessels whose impressive firepower came at the expense of armor. Glass Cannons, in large squadrons these can easily overwhelm larger vessels by weight of fire.

====Destroyers====
The most common warship class. Their tasks range from scouting to shuttling VIPs or fighting in fleet engagements in large squadrons. Most pirates use these speedy, nimble vessels to prey upon transport ships.
*'''Basic:''' Usually mounts Prow Torpedoes and a Macrobattery.
**'''Cobra Destroyer:''' The PT-Boats of the Imperial Navy. Small, fast, and lightly armed, their one purpose in life is to fire shoals of torpedoes from 3-8 ship squadrons. A great part of the Imperium's military advantage (in fluff and [[Battlefleet Gothic|on the tabletop]]) comes from all the torpedoes they can fire at the enemy, and the Cobras are a big part of that.
**'''Infidel Raider:''' Was meant to replace the Cobra, but the plans [[Blood Ravens|were stolen]] by Chaos. Armed with Prow Torpedos and a Macrobattery like its predecessor, though some Chaos fleets upgrade them to Heavy Raiders by adding another Macrobattery.
**'''Iconoclast Destroyer:''' If there ever was an Guardsman of starships, the Iconoclast is it. A destroyer so shitty the Navy doesn't want it, the Iconoclast mounts 1-2 macrobatteries and is used by Rogue Traders, Chaos and Pirates. Notable for being one of the few ships to have a forward placed bridge, likely due to the smoke-stack like pylons along its spine.
*'''Torpedo-boat:''' Why waste space on pop guns?
**'''Viper Destroyer:''' Given GW's naming conventions, it was inevitable somebody would do this. Not to be confused with the Sloop below, this is a variant of the Cobra where the guns are replaced by torpedoes. Weak against escorts but deadly in numbers against capital ships. Use [[Boarding Torpedo|Boarding Torpedoes]] for hilarious results.
*'''Lance-boat:''' Rather rare among Raiders, as most use their Prow slots for Torpedoes.
**'''Apostate Heavy Raider:''' A variant of the Infidel. Somehow those heretics managed to shove a full sized Lance into a Dorsal slot, which only Light Cruiser and bigger can normally manage.
**'''Idolator Raider:''' Also known as the "WTF is this" ship, the Idolator is the lovechild of a Infidel, a Firestorm and Xenotech. Has a prow lance and a macrobattery.
*'''Other:''' Mostly weak scouts.
**'''Viper Scout Sloop:''' Smallest warp-capable ship in mass production. It is an exceedingly fast scout ship with ridiculously powerful realspace engines and high-tech auspex scanners. In support of Naval Operations these vessels would burn into enemy territory at high speed, collect as much information as possible and then warp back to friendly territory. Unfortunately they are so specialized that they can't do much else apart from that.
**'''Rudense "Class":''' A small ship designed post Gathering Storm to be as fast, heavily armed, and densely armoured as possible, which they do with aplomb. You may ask yourselves, why are they not used in more regular combat roles? Well, the answer is that they are a specialised orbital insertion ship - designed to get as close to the atmosphere of a heavily defended planet as possible, drop it's cargo of primaris marines into the top layer, and get out of there. Whilst this may seem too specialised to be practical, few enemies are ready for half a company of marines dropping in to their base unexpectedly. (Nb - the class hasn't been formally named yet but the only example of it thus far was named the Rudense).

===Aircraft===
As part of the reforms falling the Horus Heresy the Imperial army was not just split into regiments to insure that no one imperial army could be self sufficient if it fell to heresy or rebellion, the army was also split from it's air power which was given to the Imperial navy. Strictly speaking all atmospheric aircraft are also part of the Imperial Navy, with only [[Phantine Air Corps| few general exceptions]].
*'''[[Fighter]]:''' The fighter's main role is to stop enemy torpedoes and bombers before they can [[anal circumference|rip your flying cathedral multiple new assholes]]. Comes in different models like the [[Fury Interceptor]] or the Thunderbolt Fighter. The main difference is that some can enter a planet's atmosphere to dogfight and/or strafe ground targets where others are limited to space combat.
*'''Bomber:''' Basically reusable torpedoes. Come in different models like the [[Marauder Bomber]] and the [[Starhawk Bomber]], but again the main difference is that some can dip in a planet's atmosphere and drop bombs on ground-pounders where others are space-combat only.

===Armed Freighter (in the Battlefleet)===
Ships bought, borrowed or stolen and then armed in the misguided attempt to boost the strength of a fleet in desperate need of ships (instead of simply using the legio cybernetica to make robots to do the monotonous manual labor so 90% of the hundred thousand crew members can be spread out amongst a hundred more warships)

===Fire Ship===
A fancy name for a fuckheug bomb. A old, damaged or for whatever reason no longer usable ship is packed to the brim with explosives and flown straight into the heart of the enemy formation. Again, Orks are busy taking notes for their Roks. Contrary to what you might think from the Imperium, this is not a suicide assignment. A skeleton crew is used and supplied with plenty of escape pods/lifeboats. The crew evacuates and the ship detonates after they are far out of the danger zone. Some captains decide to go down with the fire ship anyway. Or they mindfuck some penitents to stay and guide it to the best point of detonation. The Imperium isn't short on criminals and/or desperate underclassmen/mutants.

===Non-Warp Capable Vessels===
Vessels incapable of interstellar travel. All but the most primitive Imperial planets have them.
*'''System Ships:''' Civilian ships that do all the civilian stuff like ferrying, mining and transport. As nobody would buy models of them, [[GW]] never bothered to flesh out their canon. If armed, they are dragooned into the System Defense Force during invasions.
*'''Defense Monitor:''' Essentially, a mobile gun emplacement in space. Slow and small, it diverts all its power into the battleship-sized gun it carries. Crewed by regular Imperial Navy personnel and used to augment existing defenses.
*'''System Defense Vessel:''' The primary unit of a System Defense Force aka the [[Planetary Defense Force|PDF]] in space. Nobody knows what they look like or even what capabilities they have. It is assumed they are lightly armed vessels usually used in police actions and customs enforcement. In times of invasion, they use hit and run tactics as best they can until they die.

===Logistic Vessels===
Ships used for the transportation of cargo or individuals. The majority of Imperial ships would fall into this category.

*'''Carrack-Class Transport Ship;''' A newer version of the Conquest Star Galleon. It's a hardy vessel that can defend itself quite well against raiders. The profile even looks like a Military Vessel so opponents who can't distinguish between Imperial Ships could be scared off.

*'''Goliath-Class Factory Ship;''' An Adeptus Mechanicus vessel designed to harvest plasma from Stars. These ships supply the fuel for the entirety of the Imperium. Other ships can be fitted with Plasma Scoops to top up their own tanks but this is the true fuel-harvesting-workhorse of the Imperium.

*'''Jericho-Class Pilgrim Vessel:''' Refinery ships that have been converted into personnel carriers, the majority of which will be transporting poor-er passengers. Can't really defend itself but usually not even worth the bother for pirates.

*'''Loki-Class Q Ship;''' Converted Cargo ships designed to sacrifice some space for added weaponry. They can serve as Convoy defence in a pinch and can surprise the odd pirate who may underestimate them.

*'''Orion-Class Star Clipper;''' Blockade runners through and through. They're designed to transport low-volume but high-quality goods, even through hostile space. Speed is the name of their game. Hell, these things can put some Eldar ships to shame.

*'''Universe-Class Mass Conveyor;''' Think Super-Tanker in space. It's the largest standardized Cargo hauler in the Imperium and is 12km long. It looks freaking awesome too.

*'''Vagabond-Class Merchant Trader;''' Rather small cargo vessel but extremely common. As if to assist with its 'commoner' theme, it makes you yawn just looking at it.

==Adeptus Mechanicus ships==
Being in charge of manufacturing the warships for the other departments of the Imperium, obviously the Adeptus Mechanicus would also have fleets of its own. The official Mechanicum body that constructs and operates spacecraft is known as the Basilikon Astra. Because the Quest for Knowledge can involve long & dangerous travels into unexplored space, it is important that they be heavily armed and armored, so the Adeptus Mechanicus ships generally are overall of higher quality than standard ships, with better tecnology, weapons, and shields. Though the total number of ships the Adeptus Mechanicus has at its disposal dispersed among its many forge worlds is far outnumbered by that of the Imperial Navy, it goes without saying that those responsible for all starship construction reserve for themselves among the most powerful and best-equipped warships encountered anywhere in the Imperium.

*'''[[Ark_Mechanicus|Ark Mechanicus:]]''' If battleships are literal void-traveling cities, then Ark Mechanicus are void-traveling factories or massive laboratories, with industrial capabilities rivaling that of many hive cities, with kilometre upon kilometre of manufactoria, refineries, crackling Plasma Reactors and laboratories, test ranges, chemical vats and gene-bays. This kind of battleships are incredibly large, nigh-mythical ships that are said to endlessly search the stars as part of the Adeptus Mechanicus Quest for Knowledge, being led by a Venerated Archmagos Explorator. An Ark Mechanicus is outfitted with the most powerful weapons available to the Imperium, generally having a balanced set of macro-cannons, lances, launch bays & a Nova Cannon; Because the search of STC into the unknown can be THAT dangerous.

*'''Adeptus Mechanicus Cruiser:''' Besides vanilla cruisers, the Mechanicus have its own original Cruisers & Light Cruisers, that have better equipment than Imperial Navy cruisers, many times they tend to have nova cannons and that they use servitor slaves instead of human slaves, and occasionally use auto-loaders. In resume, take Imperial Cruiser but quit the typical imperial armored prow, make it shinier, give it better weapons, and can put a nova cannon as a plus.

==Important Details==

===Crews===
''Navy crews are made up of officers, techpriests, slave drivers, and slaves.''

A bit of an over-simplification, but broadly true. Due to the Imperium's aversion to AI and Automation each ship needs at least thousands of people to man it. Whenever the crew count gets low, the Imperial Navy sets up fake strip clubs on a planet claiming "Free Hookers" to lure in unsuspecting men (and the occasional woman). Once a future crewman steps in, he's knocked out, bound, gagged, and taken to the ship, [[grimdark|where they'll slave away the rest of their soon-to-be-short existence]] doing everything needed to make flying through space and fighting in the void possible.

This includes dragging shells the size of houses into cannons while being whipped. Still, at least for the crew sex is allowed, in fact encouraged, if for no other reason than maintaining the crew complement. Seriously, whole fucking cities and civilizations arise from the more massive ships, every bit as intricate as a long lived Hive City. [https://www.youtube.com/watch?v=ax7wcShvrus Here is an idea of how it works, right up to the Roman armor, whips and beatings.] Oh and apparently besides whole civilizations, there are whole civilizations of mutants around too. They can more or less settle new worlds for da [[Emprah]] by simply disgorging their excess population, which the crew is probably all too happy to do.

One area where fluff [[Black Library|hasn't been consistent]] is in the uniform worn by Imperial Navy crewmen. Some sources suggest that uniforms are divided by segmentum of the Imperium, while others suggest that it is a sector-by-sector fashion choice. Given the scale the of the Imperium and the fact that Navy fleets are already identified by hull color, it's probably on a segmentum basis, but [[Games Workshop]] doesn't care enough to make a decision about it. For the ranks of the aforementioned shell draggers at the bottom of the naval hierarchy they'd wear a motley collection of their old civilian clothes and whatever they could scrounge up and sew together.

===Travel===
The ships of the [[Imperium]] travel through the [[Warp]] using what's called a warp drive to get to where they're going. However, this isn't your happy, fancy tunnel-of-light like in Star Wars, or everything-moves-fast Star Trek, it is an alternate dimension full of [[Chaos]]. In order to avoid being turned inside-out (think Event Horizon) and getting hentai-raped by every daemon in the warp, the ships rely on what is called the [[Gellar Field]] to keep the [[furries]], undesirables, and various other evil beings out of their ship when traveling through. The Baroque decorations are also implied in helping to ward off said daemons. They rely on a [[Navigator]] that uses the [[Empra]] as a beacon to safely navigate the Warp, hence the title "Navigator".

==Ranks in the Navy==
While the Imperial Navy uses a lot of the ranks in similar fashion to modern militaries, they invariably hold to a more archaic form and are not equivalent to modern day ranking systems. Particularly since it's quite clear that commissions in 40k can often be purchased rather than earned, and that a "Warrant" would most likely hold to the original term and be an "officer by appointment" rather than an enlisted grade. Though considering the immense variety of units within the Imperium, this may not necessarily be the case galaxy-wide, so all options are equally valid. Also, the ship commander will generally be referred to as Captain internally for the sake of simplicity, except in Astartes fleets where they are called shipmasters to avoid confusion regarding the actual rank of Captain in the Astartes.

===Officer Ranks===
*'''Lord-High Admiral of the Imperial Navy''' - This guy is a [[High Lords of Terra|High Lord]] and is the single dude responsible for the '''ENTIRE''' Imperial Navy, though likely he doesn't do much other than delegate to his subordinates and attend tedious High Lord meetings.
*'''Lord-High Admiral''' - There are five of these guys, one for each Segmentum. While they're probably never anywhere near the front lines they probably have more to do, since its their job to oversee the deployment of fleets and materials from sector to sector.
*'''Lord Admiral''' - The guy in charge of a sector fleet who gets direct command of vessels and formations. You see these guys in the fluff quite regularly when "key" worlds ''(like Armageddon)'' need defended or attacked.
*'''Solar Admiral''' - Often a ''terminal'' rank... no really. Occasionally regular Admirals who do good jobs can put themselves forward for promotion to this position, which needs to be approved by the Lord-High Admiral of their Segmentum, then the officer needs to travel to Terra be reviewed by the Lord-High Admiral of the Imperial Navy. Obviously this can take a very, ''VERY'' long time to approve. So they might often be [[Grimdark|dead before the paperwork gets rubber-stamped]]. If they do get approved they are likely to get promoted straight up to sector commander (see Lord Admiral) as a position will probably have opened up while he was waiting. More rarely, Solar Admirals can get sent on "detached duties" which is basically a license to do as they please with their independent fleets.
*'''High Admiral''' - Commands several group of naval fleets (e.g. Battlegroups), often the most senior Navy officer in a Crusade but the things these fucks usually do is just having snacks with their Imperial Guard counterparts and leaving the combat duties to their subordinate Admirals
*'''Admiral''' - Gets put in charge of a fleet and told to oversee some subsectors. He's usually the highest of the "front line" ranks and much of his time will be on active duty patrolling his assigned region.
*'''Vice Admiral''' - Fleets traditionally get split into three parts, with the highest Admiral taking up the portion containing the larger ships, while the "Vice" Admiral takes the "Vanguard" portion of faster moving ships.
*'''Rear Admiral''' - the third portion of a fleet would be the "Rearguard" and usually gets assigned to the youngest/least experienced Admiral in the fleet. His job is usually the quietest one as he gets the mop-up and repair duties.
*'''Commodore''' - an experienced Captain in command of a squadron of capital ships. It's traditionally only a temporary rank, as capital ships don't always get assigned to each other the same way that escorts do. But the realities of war often mean that ships stay together for extended periods, often well beyond the lifespans of generations of captains.
*'''Lord Captain''' - not actually a rank, but an honourific applied to Captains of detached vessels operating independently. The '''"Lord-"''' part implies that they operate with the full authority of the the Imperial Navy when they act so they can deal with outside organisations (like planetary governors, Space Marines or Imperial Guard) on relatively even footing. Sometimes also known by the more archaic term of "Flag-Captain", since as the commander of a detached vessel they figuratively carry their own flag.
*'''Captain''' The commander of a single capital ship or the lead starship in an escort squadron.
*'''Commander''' - Usually the commander of an escort vessel. Is also the ranking officer on board orbital space stations. It also gets used as the terminal rank amongst Pilots, since small attack craft all fall under the remit of the Navy; so a '''Wing Commander''' would get command over all pilots based on a single carrier.
*'''Lord Lieutenant''' - The second-in-command to captains of capital ships, bizarrely Commanders don't hold that role and hold their own positions. Thankfully because a chain of command exists in any military, despite a Wing Commander holding higher "actual" rank over a Lieutenant on a carrier vessel he would not hold any higher authority on that ship than his duties allow for.
*'''Lieutenant''' - a "working" rank. Either holds command over small system vessels or acts as second in command to Commanders of escorts, or as department heads on Capital ships. They are also Squadron leaders amongst pilots.
*'''Sub-Lieutenant / Ensign''' - Team leaders or attack craft pilots
*'''Midshipman''' - Apprentice officers who haven't passed any exams or earned any responsibility, they would exist below the Warrant Officers in terms of authority, despite holding a commission. Midshipmen are commissioned from Imperial Nobility as part of the [[Administratum|Imperial Tithe]] ''(which can mean virtually anyone gets the job if they send their useless heirs just to keep the best ones at home)'' but they are also assigned from the [[Schola Progenium]]. In addition, Midshipmen also may be taken on as a personal favour from the Captain of a vessel if he knows the family. This echoes the ancient real-world practice of young noblemen showing up while the vessel was in dock with a letter from their family and being granted a commission on the Captain's say-so.

===NCO Ranks===
*'''Ship Master''' - the most senior Warrant officer on board a starship, also quite possibly the busiest man on the starship. It's his job to maintain the logs, update stellar navigation charts, oversee ships stores and order supplies, and command a hangar deck if there is one. Basically he's the guy who knows the ship better than anyone. In real-world historical usage, this guy would have an authority equivalent to a Lieutenant on board a starship, and would "mess" ''(ie: occupy the same space)'' as the other officers do.
*'''Bosun''' - ''(Shorthand for Boatswain)'' The NCO directly responsible for all of the common crew members, including [[Commissar|maintaining discipline]]. Despite his position, his actual rank may vary depending upon the size of vessel or operational requirements, in practice it never really matters since he's unlikely to ever meet another Boatswain. ''(real-world Boatswains are typically petty officers or warrant officers, but could be of any rank. They held responsibility over all areas of the ship other than Engineering, which was left to the Chief Engineer, as if the bosun disciplined/executed/imprisoned a skilled crewman from that department the ship could be crippled because of it)''.
**Note that most Capital Ships, but not all Escort ships, may have an actual Naval [[Commissar]] on board in this role, tasked with maintaining discipline up to and [[Blam|including]] the Officer compliment.
*'''Chief Warrant Officer''' - Also called "Chief Petty Officer" on some vessels. Will often be given command of important ship sections ''(like Chief Engineers, helmsmen, or auspex control, as these are are critical to ongoing operation of a starship)''
*'''Warrant Officer''' - You'll find lots of guys of equivalent rank on a ship, in command of various operational sections keeping the ship running at all times:
**Masters of Ordnance - make certain that Torpedoes and Attack craft (if any) are fueled and maintained.
**Master Gunner - have responsibility over all of the weapons batteries through the Gun Captains and make ensure they are loaded and fired when required.
**Master-at-Arms - responsible for all "small" arms on board a starship, overseeing all Sergeants-at-Arms, as well as maintaining order over any barracked Guard regiments currently in transit.
**Master of the Vox - making sense out of the bazillions of messages that run through the bridge at any given moment both internally and externally ''(crews can get pretty massive, and a lot of traffic can come through at once)''.
**Steward - the guy who keeps everyone else well fed.
*'''Gun Captain''' - Funnily enough, the man in charge of a single gun crew. Makes sure that the weapon is taken care of, is reloaded quickly enough, and is accurate when asked to fire. All of that comes back to this guy.
*'''Sergeant-at-Arms''' - Man in charge of the weapons lockers and leader of boarding parties, as well as maintaining ship-board security. Usually they are transferred from [[Imperial Guard]] regiments so that they don't have any prior association with the crew.
*'''Armsmen''' - Crewmen trusted to carry weapons more than a standard issue Lasgun/Laspistol. They are not true soldiers as offensive boarding actions tend to be rare. So these guys still have their own regular responsibilities on board ship. Since they are trusted more, they have slightly more freedom to move around the vessel as well, though most Imperial employees really don't want the job, since it means they get scrutinised more, or they could end up beating up their buddies.
*'''Voidsmen''' - the lowest rank of crewman on board a Naval Starship above the [[Servitor]]s unless the Captain is cool with slavery. If they have a skill or a trade they may be referred to as '''Able Voidsmen''' which is an official rank that might require examinations. Additionally, if they show leadership qualities they might be promoted to '''Leading Voidsman''' and put in charge of work gangs and be considered for promotion to Warrant Officer if a position opens up.

==Notable Problems==
These are problems some have with the Imperial Navy and their fluff....

===General Logistical Problems===
The big problem that the Imperial Navy has is that it's the only organised navy in the galaxy that's trying to defend its massive amounts of space. To do this takes vast numbers of ships but rather thinly spread out. Given the problems of warp travel it's also extremely hard to reinforce friendly fleets under attack. The foes of the navy come essentially in two flavours; raiders who might just manage to scrape together a few converted transports (building even escort-sized ships is a huge undertaking, akin to building damn near the entire American Navy combined from iron ore and making it fly) which take an escort squadron to murder, and huge organized invasion fleets that take a whole fleet to fight. These combine together to mean that outside of fleet bases and important strategic worlds there is nowhere in the Imperium that is actually well-defended. At best a fleet has to be formed and sent out and they could arrive months later. Travel takes a lot of time, and out in the void it can be extremely hard to know what you are actually fighting against, especially since the enemy tend to kill anyone who tries to look at them. So when there's a large enemy force that you absolutely must fight (not fighting is much preferable) you don't just band together whoever was within shouting distance of the flagship and go murdering, you pull together every single vessel in the sector and hope to the Emperor it's enough to do the job.

TL,DR: Acquiring a force sucks when command thinks paperwork and red tape are forms of worship and maintenance thinks the toilet needs a prayer before it is unclogged.

Warships genuinely are vast things and obscenely expensive and risking them at all in major actions is not something anyone does lightly. Each cruiser is larger and more complex than a fully-kitted titan legion. These things are MASSIVE. In the BFG book there's a fluff story of a cruiser being built at a shipyard that orbits a primitive world. The entire population of the planet were given over to mining the resources needed to build one single cruiser. It took them eleven years to mine the ore. Sure, that's a primitive world, but if you think about it that makes carving out the rocks for it the largest single project ever engaged upon without mechanization. If you add together all seven wonders of the world you aren't even close to the pile of rock we're talking about. So these things are a big fucking investment and the high lords really don't like risking them without a really good reason (<s>makes you questioning why they wouldn't build 20 smaller ships instead</s> ship sizes don’t work that way; 20 smaller ships against something capable of killing fifty ships that size is stupid so you build the one large ship so it lasts long enough to be a real threat, that said sacrificing escort and cruiser construction to a slightly smaller number to produce more raiders and destroyers to hunt enemy raiders and target vulnerable enemy populations would be a good idea).

So if you ever wondered why the Navy doesn't get more action, now you know. By the time the big, awesome ships get on the scene the invasion already probably finished and the bad guys moved on. Then you nuke the shit out of them from orbit or drop millions of poor bastards into the meat grinder. Far better idea all round. It's the reason that the enemy, even nutters like Chaos, don't fight in the void without reason. On the ground it's just a scrap, and maybe you win or maybe you don't. If you lose in the void then your campaign on the surface is dead. No reinforcements, no support and a massive constant orbital bombardment to kill everyone left (which sometimes doesn't happen, because, you know, <s>plot armour</s> shields, enemy surface-to-space weapons, don’t want to destroy your own territory when you can send mooks to reclaim it, etc.). That tends to mean fleets hover around and not fighting, one ensuring the other can't directly interfere with the surface war. This is actually an excellent and realistic explanation for why there is significant ground warfare in 40k. Also, ground-based defenses, mobile theater-shields, etc. are common. So, attacking a planet worth anything is like attacking a planet-sized Death Star without the super-weapon. Your ground forces taking out shields and anti-space batteries is critical to achieving anything. But, by that point, most of the enemy is dead and the survivors have either moved to the next defended region or got so stuck-in with your dudes that you can't shoot without killing your own army. Unless you worship Khorne, in which case you really couldn't care less who you kill, even yourself.

So, the navies of the galaxy ultimately get pushed down into either raiders, escorts against raiders, raider-hunters, or babysitting and logistical duty for groundpounders. Which of course brings back the question of why the Navy has such a desire to get more interceptors and bombers for ship-to-ship combat when they rarely engage in combat in the first place and the attack craft are insufficient. Could be to weaken the enemy ships' ability to shoot at the surface, but by the point they would have a target it would have (as stated) gone to a new defended location or whatever else, defeating the point of sending attack craft to weaken the enemy ships' offensive power. They won't shoot at each other, and they can't shoot at the surface (or at least can't shoot anything worth shooting at). In exchange for packing in so many attack craft into hangars designed for countless atmospheric air support fighters and bombers, the Imperial Guard has to die in radically greater numbers than they have any need to since they have limited anti-air capabilities and all of their enemies have no problem sending massive swarms of fighters and bombers at them. That is without even getting to engage the enemy on the ground and not counting the countless soldiers killed as the transports are shot to pieces due to their escorts commonly ditching them to go after obvious bait tactics. Against orders, by the way. Not that they’re ever disciplined for it. Attack craft would be useful for hunting raiders and defending convoys and transports. Maybe that is the Navy’s thinking: “If I had more Furies and Starhawks, I could send them to de-fang attackers of the troop transports and keep the ships that would have been escorting them.”

Thus the rumor that the Navy has no balls. But who needs balls when you have a nova cannon sized dick and eighteen dice worth of fire power.

===Ship Size===
No one is quite sure how big the ships really are. One story claims the Retribution-Class is a mere 3 kilometers long, while another says it is 9 kilometers and up to 20 kilometers.

Your best bet is Rogue Trader, although going by those figures, anything bigger than a cruiser has an average density around that of hydrogen... From a helpful poster on [http://www.heresy-online.net/forums/showthread.php?t=63267&page=2 Heresy-Online] we have this:

For the most accurate scale, look towards the Battlefleet Koronus Expansion, as it is more a stat/rule book than a story. That and previous consensi, as well as cross referencing with the Horus Heresy rulebooks by Forge World (which places Battleships at 8-12km) place Cruisers just above 5 kms, and Battleships in the mid 8s. Please note that most ships above the size of 8ish kilometers are either a unique modified/purpose built flagship or a ship of a small class that is not in widespread calculations. For a sense of scale the largest warship in the world is currently the US Navy's Ford Class Aircraft Carrier measuring in at 337 meters long or 0.337km making the USS Ford the size of a cannon. They have guns literally the length of an Aircraft carrier!

Ultimately, direct numbers are likely useless. The lance turrets have been described as the size of cities and given the size of an Imperial or even a modern city...also, there are about 75 ships in a Sector Fleet. A sector is one thousand cubic lightyears and there are about a thousand sectors in the Imperium. Which means logically those ships should be incredibly massive and easily ten or even a hundred times larger than the size numbers given in fluff given the size and industrial might and manpower of the Imperium.

*Transports and other Attack Craft, typically rated for atmospheric operation; also includes ships designed to be boarding torpedoes.
**<1 kilometer. That's the small ones, there are super transports in 40k as well. (A [[thunderhawk]] would go here).
*Escorts are "small" ships, like the Cobra, designed to flank foes and operate in squads.
**1-2 kilometers.
**Heavy Frigates
**Frigates
**Corvettes
**Destroyers
**Freighters
*Light Cruiser, a smaller Cruiser.
**3-5 kilometers.
*Cruiser, the standard fighting vessel; every Imperial fleet has them.
**5-6 Kilometers.
*Battle Cruiser, a beefed up Cruiser; generally more 'modern' than a Grand Cruiser.
**6-7 kilometers.
*Grand Cruiser; pocket-sized Battleship, very old.
**7-8 kilometers.
*Battleship; the biggest of the lot, simply put.
**8-12 kilometers.
**Battleships
**Fleet Carriers

The Horus Heresy novel "Know No Fear" had this to say about ship sizes, taken from [http://archive.foolz.us/tg/thread/22848349/ /tg/] who quoted it from the book and written here is just the lengths and names of the ships, for simplicity and space:

*Macragge’s Honour. Twenty-six kilometers - Flagship
*Spirit of Konor. Seventeen kilometers - Battleship
*Antrodamicus. Twelve kilometers - Grand Cruiser
*Antipathy. Nine kilometers - Cruiser (note that the book said it had "six thousand lives" on board, which would be an absurdly small crew for its size by 40k or even 21st century standards - Cruisers normally have 85-95 thousand crew in 40k, and that's for normal sized ones, not double length ones like this one. But this is a Horus Heresy ship, so perhaps it's automation was much better then a later 40k ship)
*Aegis of Occluda. Seven kilometers - Class unknown
*Gladius. Four kilometers - Escort
*Then there is the Abyss-class created by Lorgar that is said to match the Phalanx in size. He made three of them.

===Weapon Effects===
If the weapons can annihilate a continent, why can't it destroy a mere hive? Because different writers don't talk to each other that's why. Also shields maybe.

Alternate take: Sure these weapons can destroy continents, but generally speaking why would the Imperial Navy want to bombard a probably Imperial Hive? Another thing to consider is that while Imperial warships are capable of *BLAM*-ing a planet, it requires a lot of ships firing either specialized planet-killing ordnance or just bombarding round the clock. One virus bomb/Cyclonic torpedo/lance shot would do comparatively little damage. But it does make you think about how powerful those void shields must be.

Another take: Something to keep in mind is the different size of ships and thus cannon barrels. A Retribution-class battleship is a lot bigger than a Mars-class battlecruiser is a lot bigger than a Turbulent-class heavy frigate, just to name a few. Different ships have different weapons.

Another Alternate take : The heresy novels elaborate a little on little on the practicalities of Orbital bombardment as a battlefield weapon. Whilst it is occasionally used tactically and reserved as a strategic level weapon, it requires utterly pinpoint accuracy (targeting being off by a millimetre in orbit could result in a shot being kilometres off on the ground) which is only possible when orbit is completely uncontested. It's use during land battles is the VERY definition of Danger Close and often a dead giveaway to the enemy, as allied forces have to withdraw kilometres away before ordering a bombardment, letting an enemy force bunker down or get out the way. Ships are also very easy targets for anti-orbital weapons during bombardment and the effect of a starship hulk hitting a planet you're fighting for is not something to be risked.

Alternate alternate take of an alternate take take: Hives are designed to withstand bombardment from orbit while firing back with enough power to make enemy ships stay away. This is the main reason why massive ground engagements happen (and there are theater shields available, too). For example, the Rock of the Dark Angels survive Caliban being essentially turned into its component atoms via mass bombardment. Also, the previuos "Another Alternate take" directly above this one is right. Now combine that take with this one and really the only way to take an enemy position is to get off your ass and do it yourself the manly way.

Alternated take because alternate takes on alternate takes don't take what it takes: most weapons are jackshit useless against a planet with atmosphere and magnetosphere. Nova cannon shots, plasma bursts and lance batteries are distorted by magnetic fields, macrobattery shots burn up in dense atmosphere, just like torpedoes and most void-faring attack craft.
To fire effectively the ships either have to come CLOSER into low orbit (being exposed to oversized cannons and missile launchers that can be seen around every major spaceport and hive city) and risk being burst open like a pinata, or are forced to just shit bombs from high orbit, being absolutely horrible at aiming.

===Lack of Balls===
It is well-known that most Imperial Navy Officers don't have em.

An Imperial Navy fleet is most effective when Inquisitors take it over. [[Exterminatus|See Here]].

===Carrier Hate===

Back in M36, the Imperial Navy fought a lowkey civil war over fleet doctrine in Segmentum Tempestus known as the Gareox Incident. A cabal of chaos worshipers worked their way high enough in the navy to start designing ships that were ready-built to turn traitor, most of which were carriers. The battlefleet eventually figured out something was off and the result was a giant carriers vs battleships fight that went down the way the Battle off Samar would have if the Japs hadn't been scared shitless by three destroyers. The surviving carriers went openly traitor and since then building new carriers has been borderline heresy so far as the navy is concerned. They don’t hate carriers, but many Imperial ships are basically battlestars, making carriers a pointless waste of resources. Attack craft are mostly used to weaken enemy firepower, shoot down torpedoes and enemy fighters and bombers and boarders, and finish off crippled enemy ships. On their own, they’re largely useless for actually defeating enemy ships. The main reason aircraft are so effective against navies in WW2 and modern navies is that they can use momentum for bombs and missiles to strike hard from above in order to penetrate decks. Space has no such option and every attack from any angle is similar to a torpedo plane attack run from the Second World War. Which is why Starhawk Bombers are basically just torpedoes. However, carriers are useful and accepted, just not useful enough to bother building from scratch and so carriers are almost always either repurposed wrecks of other ships or mothballed carriers being deployed where more attack craft are needed. This almost pointlessness also means carriers are looked down on as barely worth calling support ships.

==Music of the Imperial Navy==
Not to be outdone by the Imperial Guard (as well as to compensate for their aforementioned lack of balls), the Imperial Navy has begun collecting music to either be blared on loudspeakers when not in active use, or in the case of battleship command decks, played live by orchestra. the first four are taken from [[Battlefleet Gothic Armada|Battlefleet Gothic Armada.]]

[[File:imperialnavy1.jpg|400px|thumb||Cathedrals IN SPEHSS!]]

{{Topquote|When you began, you couldn’t have possessed enough bones for the whole ship. It would look stupid with a few dozen skeletons nailed to the walls. So, how do you start? Do you save up enough bodies for a corridor at a time, or put them away until you have enough to decorate the entire vessel?’|Jain Zar,-Storm of Silence}}

{{Topquote|By my faith, may the light of the Emperor spread to the farthest star. By my duty, the galaxy will belong to the righteous. By my actions, the Imperial Navy shall be honoured and remembered on Holy Terra. For the Emperor of Mankind, AND FOR THE BATTLEFLEET GOTHIC!|Imperial Navy Captain Abridal, shorty before his blaze of glory that ultimately stopped the 12th Black Crusade and saved billions of Imperial lives.}}

The '''Imperial Navy''' is one of the main branches of the [[Imperium of Man|Imperial]] military in [[Warhammer 40,000]] (although very little of the Navy actually appears in the tabletop game). They are also one of the main factions in the beloved spin-off game [[Battlefleet Gothic]].

Unlike the [[Imperial Guard]], who get killed in the <s>thousands</s> <s>millions</s> billions every day, the Imperial Navy rarely suffers that many casualties. This is because, unlike the [[lasgun|flashlight]] used by Guardsmen, the main weapon of the Navy is a giant, heavily-armed, heavily-armored battleship that puts other races' spaceships to shame (well, except [[Necrons]]). These ships are also [[Awesome|massive, flying, Gothic cathedrals]].

Depending on how you look at it (and who you're looking at), the officers of the Navy are either wealthy cowards or badass gentlemen. In either case, their ships have crews numbering the hundreds of thousands or even millions (we're not kidding when we say that each ship has its own language(s) and culture(s)), since the Imperial Navy doesn't understand how auto-loaders work, so loading a gun requires thousands of slaves running on treadmills. Of course, this might be the fault of [[Adeptus Mechanicus|a certain other branch of the Imperium, who, coincidentally, ''do'' have working auto-loaders on their ships]]. In any case, [[Grimdark|the Imperium has found it cheaper and ''more effective'' to use manpower because they have ''that many people'' to throw at even the tiniest of problems.]] Except that the cost of hundreds of thousands or even millions of chain-gangs adds up over centuries and millennia whereas maintenance for the machinery would basically amount to "apply oil while chanting". Of course, for a major officer, most days simply require him to press a button and blow something up, then go back to drinking his tea. Oh, and ''maybe'' scramble the ground-support flyers, if he's feeling charitable that day.

Note that, back in the [[Great Crusade]], the Imperial Guard and Imperial Navy were one and the same, operating under the far-less-badass name of "Imperial Army." However, thanks to the [[Horus Heresy]], the two got split up, so that a single military commander couldn't control too many forces; a Guard commander isn't able to get off any given planet without the Navy, and the Navy isn't able to conduct wars (and, you know, occupy territory) without the Guard. You'd think that this enforced mutual co-dependence would make them collaborate, but [[grimdark|of course]], despite how much they need each other, the two bicker constantly, which, in fact, may be the reason for all the [[fail|stupidity]] the 40k universe is saddled with, at least on the military front.

==Types of Ships==
The Imperial Navy has four types of ships they hide their cowardly asses in. The main ships are battleships, cruisers, escorts, and fighters
Each ship can also be classified by its weaponry, and role in the battlefleet:
*'''Basic:''' Jack of All Trades ships, due to having multiples weapons types, and not being specialized into any. Lunar class cruisers are the prime example, having macrobateries, lances & torpedoes.
*'''Lance-boats:''' Ships that focus into Lance weaponry, used for long-range focused attacks, especially against small ships & unshielded ones. Rarer as they have a weakness to Void Shields and require better drives due to the power requirements of the lances.
*'''Ordnance-boat:''' Opposite of the Lance-boat, replaces Lances with more Macrobatteries, focusing mostly into medium & short range brawls against enemy ships. Usually this is because they need extra power due to mounting a Nova Cannon or having power-hungry macrobatteries such as Plasma Cannons.
*'''Carrier:''' The red-haired stepchild of the Navy. Replaces the Lances with Launch Bays and is disliked by most Admirals due to the stigma against Attack Craft, although it is because the Traitors & Chaos pawns focused on raiding & striking fast, so with enemy fleets focused on long range attack (Lances, laser, and attack craft)plus Chaos likes them more because they can fill the bays with Assault Boats, the Imperial Navy might have got that stigma of seeing too many Chaos carriers raiding & pillaging imperial planets & so started dislike them. Some Carriers are also made from wrecked cruisers of other types, in which case damaged broadside weapons are ripped out and replaced by launch bays.
*'''Torpedo-boat:''' Originally an experiment for escort ships to overrun enemy vessel crews using boarding torpedoes, it was doomed to failure as the targets were either too nimble or too big. The Imperial Navy kept a few as Missile Destroyers.

===[[Imperial Navy Battleship|Battleship]]===
Supposedly rare, but every Grand Marshal and High Admiral has at least one and often several or even dozens to hide in because GW is completely and hopelessly inconsistent with fleet sizes, though as of late it seems that GW is leaning towards big fleets and big armies when it gives numbers. Bonus points if that coward is also Chaos. The biggest heaviest hitters available, these things are like actual medieval cathedrals in that the grandchildren of the workers who start building them get to live to see their completion. Fuckheug, lots (and lots, and lots) of guns and most can deploy fighters and bombers.
*'''Ordnance-boats:'''
**'''Retribution:''' Packing all gun batteries, the ship can devastate an entire continent in one broadside, but for some reason cannot destroy a hive city or fort with [[void shields]] - [[What|or in some cases, ones without any shields at all]]; either that or GW was just pulling another [[Derp|Michael Bay]] out of their asses again since, they have no idea how [[Herp|consistency works, let alone basic physics.]] Of course, considering the Dark Angels fortress-monastery and the huge chunk of land surrounding it survived the bombardment which turned Caliban into a bunch of space dust, it is perfectly reasonable that something that merely glasses half a continent would not destroy a void shielded city or other major fortification. If anything, this provides a degree of insight into why land battles in 40k are so massive in the first place. Because orbital artillery doesn't have many targets of opportunity it is actually capable of exploiting without tearing the planet to pieces.
**'''Invincible:''' An interesting class, dubbed a 'fast battleship', these were designed to chase down xenos and chaos raiders, and then use them to make the vast, empty tracts of space more interesting by filling it with their enemies' debris fields. This type of battleship combines the firepower of a ''Retribution'' with the speed of a ''Dauntless''. The problem with this is the general incompetence of Imperial tacticians. It looks exactly like a ''Retribution'' and has the guns to match, so it must be one, right? NO. They excelled at the role they were designed for, but throw them into gunfights against dedicated battleships, and these things tended to come apart easier than wet cardboard, earning them the nickname 'Kisher's Kombustibles' and the scorn of many admirals. Admirals who ignored the fact that the reports detailing the introduction of the ship and how to best use it (it's tactics also included in the Tactica Imperialis) explicitly state not to use it on a gun-line and that it is for fast-ship interdiction. The ship's Commissars must be particularly incompetent to let this slide as in the Guard the generals would be executed quickly for such incompetence. Of course, these are also the Commissars who do nothing when troop transports' escorts frequently run off to fight while the transports lose a significant percentage of their ships. Perhaps if they would actually enforce their orders to stay with the transports, the Imperium would have won most of the campaigns it has lost. Given that they still often win even with a fraction of their beginning ground forces actually managing to make landfall. [[Grimdark|Because they have THAT many men to throw at the enemy.]]
***Much like the Chalice-class of Battlecruisers, the Invincibles are a big reference to the real life Battlecruisers of World War 1, especially with the term "Kisher's Kombustibles" (real life Battlecruisers were referred to as "Fisher's Combustibles") and the fact that three blew up in a single battle (referencing Jutland).
*'''Lance-boat:'''
**'''Apocalypse:''' One of the oldest ship designs (predating the ''Retribution'', which is also one of the oldest ship designs), this ship packs a lot of [[lances]] and a [[Nova Cannon]]. Good for taking out lots of smaller sized ships with massed lance fire. It's also described in fluff as being able to cripple anything up to a cruiser with a single, concentrated broadside. They're fairly rare, since the Imperium doesn't know how to build them anymore, and the ones still operating are so old, their weapons systems have degraded permanently, forcing them to fire their lances at only a fraction of their full power. Shares all the disadvantages of a ''Gothic''-class cruiser.
***Despite the fluff stating that the Apocalypse and Oberon classes are unique in that they lack figure-heads, the artwork and [[Crunch|models]] [[Derp|give them one anyway.]]
**'''Victory:''' Possibly an attempt to recreate the ''Apocalypse'' class, the ''Victory'' is basically a ''Retribution'' with a bunch of lances replacing its broadside cannons, and a Nova Cannon instead of torpedoes. Has the range that fluff states the ''Apocalypses'' once had, but lacks the same level of firepower. Effective at sniping, and hilarious when used against escort heavy fleets.
**'''Desolator:''' A ridiculously old design. Designed to emphasize range and carries Torpedos, Broadside Lances and Dorsal Macrobatteries. Like most keel-built ships, the Desolators ended up mothballed or went traitor.
*'''Carrier:'''
**'''Emperor:''' The "standard" battleship of the 40k 'verse, the ship has multiple fighter decks and weapons batteries. Unfortunately, most commanders like to use this ship as a hideout, causing the lack of sufficient air support in the ground wars even though the Navy's atmospheric aircraft are completely different from its much bigger space based strike craft. Tabletop-wise, its status as the official battleship of Battlefleet Gothic doesn't stop it from losing carrier duels against the Chaos equivalent.
***Ironically, the idea of the Emperor being the standard battleship conflicts with the fluff about the Navy hating Carriers. Go figure. Except it doesnt. Because the Imperial Navy isnt fond of carrier ships, but that doesnt mean they dont use them; So if you were an imperial admiral, would you choose to get multiple smaller carriers, at the cost of having less ship-of-the-line on your fleet? Or would you instead get a 8+ kilometer battleship with four city-sized hangar bays, having higher detection, and being capable of helping your fleet & any warzone in multiple ways (Not just void warfare, but also ground support in planet invasions, or logistical support) without the need of going too close to the enemy? Its no wonder the Emperor Class is so popular & useful in the Imperial Navy, looking at this way, in reality, the Emperor class goes well precisely on the conventional Imperial doctrine because of this reason. Despite the (idiotic) distaste Admirals have for strike craft, they will use still use them out of simple utility and they figure they might as well get something that can do more at the same time.
**'''Nemesis:''' The super-carrier of the Imperial Navy. It has SIX flight decks (the size of towns or small cities, each), more than any other ship in the galaxy. But because of Rule of Cool, it is incredibly rare since the Navy captains prefer to get up close broadside their enemies, or actually rather because all of the ships in this class were just ships modified from Emperor class ships in one particular war, because they were damaged or otherwise. Naturally, the Navy never considers making them based on the Invincible instead (the Invincible was mass-produced).
**'''Desecrator:''' The carrier variant of the Desolator. Replaces half the Broadside Lances with Landing Bays. Shared the same fate as its sister class and is now only seen in Chaos fleets. Traitorous despite its clearly pious and Emperor-loving name.
**'''Despoiler:''' Oh boy, where do we start? The Despoiler-class came about after the cogboys discovered plans for a carrier on Barbarus. The catch? Well, Barbarus is the former homeworld of the [[Death Guard]], and the plans were for the same class of ship that the [[Terminus Est]] is a part of. Showing a complete lack of common sense, the Imperial Navy decided to build ships of this class, only for them all to go traitor due to the class's inherent [[Gellar Field]] flaws. [[Fail|Oops]]. The Despoilers at first don't appear to be that unique, as they have Dorsal Lances and Broadside Landing Bays and Weapons Batteries. Their difference is that, like the Terminus Est, they managed to have a Prow Landing Bay as well.
***Despite being a new class, GW fucked up their fluff and had [[Rogal Dorn]] disappear aboard a Despoiler, [[What|5000 years before the class was created]]. Note this class was actually already named "Despoiler-class" by the Imperium. Yet, they were ''surprised'' the things went traitor. Wow. Also, after fixing the Gellar Field problem, the Imperium still decided not to build more, which was stupid since there was no longer a reason not to. I get not wanting to chance it, but beggars can't be choosers.
*'''Other:'''
**'''[[Gloriana-class_Battleship|Gloriana]]:''' Massive, terrifying and capable of decimating entire fleets on their own, these were the personal flagships of the Primarchs during the Great Crusade. Very few, if any, are still around in the Imperium in M41, though a few such as Horus's flagship ''[[Vengeful Spirit]]'' are still tooling around inside the Eye of Terror. Because they were dickheads, the [[Alpha Legion]] had two, creatively named the ''Alpha'' and the ''Beta''. Interestingly, the Ultramarines have one, the ''[[Macragge's Honour]]'', but didn't [[derp|fucking]] use it, the whole fucking time until [[Roboute Guilliman]] returned. It shows up again in ''Dark Imperium,'' with the Smurfs having stolen it back from the Red Corsairs, which at least is fucking funny even if it makes no sense. The Imperial Fist had the ''Eternal Crusader'', but it was never their flagship since the [[Phalanx]] is so much better, so [[Rogal Dorn]] gave it to the [[Black Templars]] in the [[Second Founding]]. The Emperor is known to have had at least one, called the ''Bucephalus'' (also the name of the horse of Alexander the Great... coincidence?), which he ditched after upgrading to an enormous golden space palace called ''Imperator Somnium'' for the sole purpose of flying him back to Terra to retire. Wait, did Emps just see the Phalanx and decide to build his own bigger better version?! [[Eldrad|DICK]].
**'''Oberon:''' The mixed-breed bastard of the Imperial Navy. It has [[lances]], fighter bays, and weapon batteries. Its a powerful ship... <s>when fighting foes half its size</s> "Newer" fluff says the Oberon is rare, but a complete success in making a ship capable of killing anything it comes across, alone. Unfortunately, fluff also says a ridiculously low number of these (apparently) powerful ships were made (like, 3 or so). Then again: only four Iowa class battleships ships were built (technically 6, but 2 were scrapped before completion), and we know HOW to build them. It makes sense in a way. Attack craft can cripple an enemy's main weapons and engines and likely ultimately damage the power transfer from generators to void shields. Combined with macro-batteries hammering away and the enemy's weakened ability to maintain its shields would cause them to drop much quicker than usual. Then the city-sized lance-batteries rip the enemy in half. If used against enemy escorts to support attacks on large enemy ships like battleships and grandcruisers, this would work extremely well to the point an Oberon would likely become a priority target for enemy ships.

===[[Imperial Navy Grand Cruiser|Grand Cruiser]]===
Only slightly weaker and less powerful than Battleships, Grand Cruisers were the weird middle-child of actual Line Ships (that really were the mainstay of the fleet back then) and Cruisers in the ancient Imperium. Built primarily with autonomy in mind, those were reserved for the most daring expeditions in the uncharted regions, conducted both by Imperial Army and Rogue Traders. Nowadays most of them run on archeotech that is barely understood and hard to repair with current Imperial knowledge. These grand ships are often used as flagships in lieu of extremely rare Battleships. Basically, they are the quintessential Battlecruisers; tougher and deadlier than Cruisers and yet more mobile than Battleships.
*'''Basic'''
**'''Vengeance/Furious:''' The granddaddy of "modern" Imperial warships. The ''Vengeance'' was the winner of a GW-sponsored ship design contest, and was originally known as the ''Furious''. Highlights include heavy shielding and armour (though lacking the prow armour of later designs), as well as both lances and long range weapons batteries, making this the sniper of the Imperium's Grand Cruisers.
**'''Repulsive:''' Originally named the Corinus Class, before being renamed after many fell to Chaos by an overly literal Mechanicum designation. Whilst the Repulsive Grand Cruisers are exceedingly maneuverable heavy warships (and therefore exceedingly useful because they can fill a hole in the Imperial tactical lineup), they are considered a cursed class due to the majority of them falling to chaos, [[Fail|which unfortunately was the result of experimental warp drives which occasionally interfered with the Gellar Field (OMGWTFBBQTIME)]]. Only the Emperor knows what kind of complete moron would deploy ships equipped with that. The ones that remain in Imperial control are kept mothballed in reserve fleets and segmentum fortresses (imagine giant glass boxes with 'In Case of Emergency, Break Glass' signs). It doesn't say anything about their warp drives being swapped out for something that isn't shitty or perhaps a completed and no longer experimental version of their own. Not that you want AdMechs tear off your head for tinkering with their sacred templates, on the other hand.
*'''Ordnance-boat:'''
**'''Avenger:''' The short range brawler of the Imperium's Grand Cruisers, it's a ''Vengeance'' with only macrobatteries (kilometres of Macrobattery broadsides). Intended to break the line of battle like Nelson's ships at Trafalgar, while suffering from the lack of an armored prow. Unfortunately line-breaking is quite a dangerous role for any ship, even a Grand Cruiser that excels at doing it, and so not many exist in the 41st Millennium. Those that have survived are known for being exceedingly reliable and faithful; it takes a lot of damage or mistreatment to cause these noble vessels to give trouble. If you spoke with members of the Imperium (both members of the public and the navy), this is the vessel they would think of if you asked them about Grand Cruisers. Now, if only the Imperium realized a slower but more heavily armored and shielded ship would fare better in its role.
*'''Lance-boat:'''
**'''Executor:''' The sniper of the Vengeances, the Executor replaces its Broadside Macrobatteries with even more Lances. Unfortunately, the last remaining Imperial Executors decided to act retarded and chase a fleet into the Eye of Terror, meaning that all of the ships are chaos aligned now.
*'''Carrier:'''
**'''Exorcist:''' A ''Vengeance'' that has carrier bays in place of lances. Useful in providing carrier support to any Imperial fleet. As a bonus, being Grand Cuisers mean they can outrun anything except battleships to save their vulnerable carrier self while their attack craft are away. Originally designed for extended operations alone on the Frontiers of Imperial Space, either on Patrol or by exploring into the unknown, the Exorcist developed quite a reputation for 'boldly going where no man has gone before'. Whilst not many remain in Imperial Service due to maintenance difficulties, they still find use in the hands of Rogue Traders who need vessels capable of long cruises and of defending themselves against anything they might encounter. So much for maintenance difficulties.
**'''Retaliator:''' A mix of a Repulsive and a Vengeance, but as a Carrier. Has Lances, Launch Bays and Macrobatteries on its Broadsides. Unfortunately, it has the Repulsive's tendency to go traitor.

===[[Imperial Navy Battlecruiser|Battlecruiser]]===
What do you do when you forget how to maintain an entire category of heavy warships? You build a new bunch of heavy warships, with simpler technology.

Battlecruisers are basically upgunned cruisers, with more weapons (usually adding dorsal weapons and some armor), and are intended to fill the gap between true battleships, which are rare, and normal cruisers, which tend to die really easily to the ancient Chaos cruisers and grand cruisers. Battle cruisers were tried in real life as some way to combine battleship firepower or armor and cruiser speed. They did not always work, and much like reality these things have their share of problems. Chaos operates their own versions known as Heavy Cruisers. In real life, the accepted successful form of a battlecruiser is between a heavy cruiser and a battleship; it can kill anything it can catch and it can outrun anything that can kill it (usually only an enemy battleship). After its teething years it was generally a good and effective form of combat when used intelligently.
*'''Basic:'''
**'''Armageddon Battlecruiser:''' An upgraded variant of the Lunar Class Cruiser (YAY! ANOTHER ONE!). A rather new innovation, the Armageddon class is basically made up from recovered Lunar Class Hulks that have been extensively repaired and then retrofitted with more armour and more weapons. The base hull was never designed to cope with all this extra equipment (and the extra crew to man said equipment) and so it has problems operating independently for long periods of time. This isn’t really a problem, though, since they wouldn’t be operating away from a fleet anyway. Though reinforcing its frame to handle the added mass would be a smart thing to do to save immensely in future maintenace costs over the centuries. Battlefleets won't say no to them because more guns = better! These ships are extremely powerful and live up to their name. Somehow, though, the Imperium never went “Hey guys, this thing kicks the shit out of everyone, let’s upgrade all Lunar-class ships to Armageddon-class and make a new class to accomodate the new crew and equipment.” Or someone did and was turned into a servitor...
**'''Hellfire Heavy Cruiser:''' An upgunned Murder-class. Has the same issues as the Armageddon, slow as fuck and has power and supply issues. [[What|Also, lacks Void Shields]]. Most mutinied and joined Chaos, which decided to use them for some reason.
*'''Ordnance-boat:'''
**'''Overlord Battlecruiser:''' The Classic Imperial Battlecruiser. Using the standard Imperial doctrine of - Macrobatteries, Lances and Torpedoes, the Overlord has become the most effective Battlecruiser simply because it really complements standard Imperial Navy Tactics. As an added bonus, its simplicity of design makes it easier to produce and one can be built within a decade. The only negative (if you can call it a negative), is that it's not really useful for anything except war.
**'''Chalice Battlecruiser:''' A fast heavy cruiser. Unique to the Calixis sector and an exceedingly new design, the Chalice was conceived as a Battlecruiser that could either out-run or out-manoeuvre anything it can't kill. Which means it was conceived to be a plain ‘ol normal battlecruiser. Whilst good in theory, unfortunately, speed came at the cost of armour and durability and so whilst these vessels punch hard, they can't take as many hits as other cruisers. In addition, it carries an experimental plasma drive layout, which while boosting power efficiency, also makes it rather vulnerable to lighting up like a roman candle. Imperial Propaganda is currently trying to cover up their failings and is lauding them as the Poster-ships of the Calixis Sector and therefore a lot of people think they're the 'Best Battlecruisers Eva!'. If they would just use a normal plasma drive and make the whole ship bigger, it would be fast enough, armored enough, and even better armed. Unfortunately, not being stupid is heresy in Calixis.
***The idea of a ship that can "either out-run or out-manoeuvre anything it can't kill" that turns out to be really poor at taking hits was the original design of real life Battlecruisers, which although being up-gunned Cruisers (which are the equivalent of Frigates IRL, not Ships of the Line), were used as discount Battleships at Jutland were they turned out to lack the armour required for a proper fight. Thus, if the Imperials were smart, they would be using the Chalice as a commerce raider, not a ship of the line.
**** Actually, they were not bad at taking hits, they were better at it than heavy cruisers. They just sucked at taking hits from battleships like everybody else on the planet. Real life battlecruisers (after their early screw up designs) were made only a little smaller than battleships which allowed them to have greater armor and firepower and speed than heavy cruisers and were even fast enough to outrun battleships at the cost of significantly lower firepower and armor than the only slightly larger battleships (which caused things like the Jutland kablooie). They had the whole package. In reality, the larger the ship the faster it is in navies (broadly speaking, in dense fluids the longer the vehicle is relative to its cross-section, the easier it is to go fast), sci-fi just is made by ignorrants. Battlecruisers fell out of favor shortly after they were perfected for the same reason battleships and heavy cruisers did: the carrier. That said, they were indeed usually used as commerce raiders. But that is true for all ships. Navies exist to destroy enemy commerce shipping and to transport armies. The only reason fleets engage each other is because both sides defend their own shipping and seek out enemy fleets to pre-emptively destroy to protect said shipping and transports. In 40k, it could be said that the Invincible-class is the closest thing the Imperium has to an equivalent to a real life battlecruiser.
**'''Long Serpent Battlecruiser:''' A true success story, this is what the ''Chalice'' wishes it was. Taking a battlecruiser's armour and firepower, and giving it the engine suite of a battleship, this thing can kick the shit out of anything short of a grand cruiser or battleship, while being able to keep up with raiders. It's only real flaw is that when one is taken out, it has a better than average chance of rupturing its warp drive. As a result, the names of ''Long Serpents'' that have been destroyed are usually accompanied by those of allied ships that were too close. Which is somewhat odd since the reasoning is that the Long Serpent also has a battleship's warp core (who knows why, it isn't big enough to need it). Given the small difference in size between this ship and other "normal" cruisers which are the mainstays of the fleet, the Imperium could just choose to use a smaller warp core suitable for this ship's size and focus on mass-producing the Long Serpent to replace basically every other class of ship except battleships , Cobras, and carriers. Fewer would be made but, unlike video games, swarming a capital ship with escorts does not work at all. The escorts are slaughtered and the capital ship like this one is left unharmed. But doing this would require common sense, which is [[Heresy]]. Like properly using the Invincible-class must be.
**'''Mercury Battlecruiser:''' Another fast Battlecruiser. It's a cruiser with a Battleships's engines. Nothing more.
**'''Hades Heavy Cruiser:''' A long-ranged brawler. Carries Broadside Macrobatteries and Dorsal and Prow Lances. Got phased out like most keel-built designs, but Chaos still uses them.
*'''Lance-boats:'''
**'''Acheron Heavy Cruiser:''' Designed to test new Lances and Macrobatteries. The Imperials only built one, which went traitor. Carries Broadside and Dorsal Lances with Prow Macrobatteries.
*'''Carriers:'''
**'''Mars Battlecruiser:''' In a word - Mediocre. Some Imperials say it's versatile due to its diverse weapons loadout but in reality it makes it an awkward duckling to use. The Nova Cannon and Launch bays would be good on a ship holding back and harassing enemies at range and yet it has Macrobatteries and Lances which are great for brawling. So if you sit back and harass or go in and brawl, you're wasting half your ship. The Imperial Navy never really got on with it either and so it has gone out of production on most Forge-Worlds. Which is a shame because if they would replace the macrobatteries and lances with larger, long-range lances, and a great number of small, short range weapons batteries for fighter support and self-defense respectively, this would be a great ship in any fleet. It's nova cannon clears a hole in the enemy escort screen, the attack craft rush through to wreck the weapons and engines of light capital ships while long-range lances assist other Imperial ships in slaughtering targets of opportunity. The destroyed enemy light capital ships leaves all the other big ships vulnerable to mass, concentrated torpedo attack from friendly ships. Attack craft return to the fight to tear up the no-doubt seriously damaged enemy big ships and lances win the day. Then just send in friendly light capital ships with attack craft support to finish off the surviving escorts. That would almost make this ship into a sort of miniature "I Win" button. Almost. Especially in a squadron of two, as they could assist each other against any opponents that slip through to them with their combined, close-range firepower, lances, and whatever attack craft they kept back for defense ripping the enemy weapons and engines apart to let the close-range macrobatteries have fun.
**'''Dominion Battlecruiser:''' Basically a fixed Mars, some tech priest got it in their head that, maybe, it'd make more sense to replace the Macrobatteries with Lance Batteries instead, making it a dedicated support ship, harrassing enemy ships at range whilst the big guns go out and fight. Apparently not that successful, a number were used at the Battle for Maccrage (Of course the fucking Smurfs get them) against the tyranids, though apparently they all got fucked up and have been in drydock since, which is why up until now no-one's seen them.
**'''Styx Heavy Cruiser:''' A pure carrier. Has Broadside Launch Bays, Dorsal Lances and and Prow Macrobatteries. For some reason the Imperial phased it out for the Mars, so only Chaos uses them now.
**'''Hecate Heavy Cruiser:''' An attempt to replace the Styx. Swaps out some of the Launch Bays for Macrobatteries. Believed to have an inherent design flaw that made them go traitor, so they were decommissioned.

===[[Imperial Navy Cruiser|Cruiser]]===
Cruisers are the bread and butter of the Imperial Navy. Much larger than escorts and light cruisers, but less rare than battleships, cruisers are what the Imperial Navy (and Chaos and Xenos) use to fight their campaigns across the stars. Thus far, all Imperial Cruisers have been shown to utilize the same hull-type: a squat armored prow in front, capable of mounting a prow-mounted weapon system, and a big bunch of engines in the back, with baroque and Gothic architecture in-between. Most cruisers can effectively be placed in four categories:
*'''Basic:'''
**'''Lunar:''' The Lunar. You've heard so much about it and now you want to know what it makes it the standard Imperial Cruiser. First of all, it's one of the oldest designs still in use by the Imperium and is so easy to build that even less advanced worlds can produce them. They're quite versatile due to their weapons loadout (a balanced build of Macrobatteries, Lances and Torpedoes) and make up the backbone of Battlefleets throughout the entire Imperium. This is the cruiser against which all other cruisers are measured.
**'''Emasculator:''' Considered a failure by the Imperium at large, Emasculators have the same basic load-out as the Lunar, but are keel-built, lacking the armored prow and replacing the torpedo tubes with more weapons batteries. This means they require different tactics to a Lunar, using their speed and longer ranged weapons to pound ships from a distance. As this fits with Chaos tactics more than Imperials. most of them ended up as traitors. [[/d/|The name Emasculator is due to them being seen mostly as Slaaneshi ships, their original name is unknown.]] The fact the Imperium keeps trying new ships built on the normally Chaos style hulls implies that usually it must work out just fine since otherwise it would have been banned by now. So, there are probably many cool looking keel-based Imperial ship classes floating around we'll never catch wind of ever.
**'''Slaughter:''' A special type of Cruiser, the Slaughter-class has a more powerful drive called the Scartix Engine Coil, but lacks prow weapons. Armed with short ranged, but powerful lances and macrobatteries, the Slaughter is designed to get in close, blast away and retreat. Unfortunately, the Imperium can't build them anymore because one went traitor and destroyed the plans for the Scartix Coil. It is unknown if they were always called the Slaughter-class or were renamed when most went traitor. Considering the usual lack of intelligence in the Imperium's leadership, it was probably called something worse, like the "Traitor-class" or something and then the Imperium wss shocked when they lived up to it. Really, would you be surprised if the Imperium did that?
**'''Inferno:''' A earlier counterpart to the Carnage-class, carrying more lances in exchange for some Macrobatteries. Had the same difficulties as the Carnage and was mothballed, though a few went renegade beforehand. Rare example of the Imperium learning its lesson. Still too stupid to realize that using cheaper-after-a-few-centuries-than-manual-labor auto-loaders would've fixed the problem for both ships.
*'''Lance-boat:'''
**'''Gothic:''' Another variant of the Lunar Class, the Gothic is designed as a heavy Lance gunship. Due to the amount of Lance Weaponry it carries, it can easily deal with ships of its own size or larger but often does require an escort or a partner to strip enemy void shields first in order to use its own weaponry to the maximum effect. When supported and used correctly, Gothic Cruisers are the most efficient way to deal with enemy capital ships.
*'''Ordnance-boat:'''
**'''Dominator:''' A variant of the Lunar Class, the Dominator is designed primarily for planetary bombardment and assault. Not generally used in fleet actions even though it can provide support with its Nova Cannon when necessary. After one Dominator fucked over a Chaos Cruiser with said Nova Cannon during the Gothic War, the Navy took note and started making more Dominators. [[Awesome|Additionally, another Dominator came close to destroying the Terminus Est (''aka the toughest Battleship in the galaxy''), before being destroyed.]] The Dominator possesses the same armament as the Retribution-class battleship but lacks the range of one. This is fine, though, since it's meant to get close to the enemy like most Imperial ships anyway. Basically, if you get in range of this thing, ''you're going to die''.
*** From Lexicanum 40K: "Captain Straden of the Depth of Fury defended the shrine world of Kathur to the death, and came very close to destroying the Death Guard ship Terminus Est. As it was, he and his crew vaporised several of its decks and destroyed scores of escort ships before finally succumbing. Ironically, no Imperial souls survived to tell the tale."
**'''Tyrant:''' The Tyrant was originally intended as a stand-off vessel; it would stay at long range and bombard enemies from afar with superfired plasma weaponry. Unfortunately, due to design compromises where it mixed both short range and long range weaponry to save on power, it wasn't really deadly enough at long range to do its job. Therefore the Imperial Navy is trying to replace the short range weapons with ancient Long-range weaponry (that doesn't use a lot of power) recovered from Space Hulks or Renegade Ships. The Hull itself is a rather effective design and so the Tyrant has become very popular with Rogue Traders who generally replace all of the Plasma Weaponry in order to have more power available compared with other cruisers.
**'''Relentless/Carnage:''' Another attempt at a fleet support ship with Plasma weapons, the Relentless ended up with technical difficulties and, when these were overcome, [[Heresy|most ships ended up turning traitor]] [[Fail|(including the lead ship of the class)]]. [[Tzeentch|This is theorised to be due to something wrong with the geometry of the ship's design]], as the Relentless-class is keel built, like most older ships (This also means the Relentless lacks an armored prow and torpedo tubes, carrying more plasma batteries instead). The tendency of these ships to turn to Chaos, along with changing tactics, led to the class being renamed the Carnage-class and mothballed in favor of the Tyrant-class, though their speed means they suit Chaos tactics famously.
*'''Carrier:'''
**'''Dictator:''' A Carrier retrofit of extremely damaged Lunar Class Cruisers. If a Lunar class has its lance weaponry destroyed, it's quicker, easier and cheaper to replace those with heavy launch bays for strike craft. This makes it quite versatile and able to deal with virtually all situations and interestingly enough, makes it more effective than the original Lunar Class at everything except fighting as a ship of the line. Unfortunately, the Lunar Class is designed for fighting as a ship of the line, so Admirals dislike Dictators.
**'''Jupiter:''' A kitbashed design, converted from other classes of cruiser that have been heavily damaged in battle. By stripping out all the damaged components and replacing them with launch bays, you get a pretty sturdy carrier. Just don't let the enemy get anywhere near it. Apparently the Imperium doesn't build these normally at all, likely because they are absolutely shit at defending themselves from other Cruisers.
**'''Devastation:''' Deviating from the standard Carrier design, the Devastation-class carries Lances instead of Macrobatteries. Mostly turned traitor or mothballed, as they lack armored prows and torpedos; and are keel-built. Chaos likes them, as they can pack them with mutants and sit back to spam assault boats and lances at anything that looks at them funny.
*'''Other:''' Various other cruiser types exist, but are rarer.
**'''Ambition:''' Custom-made Cruisers for the exceedingly affluent - it's the Rolls Royce of the Cruiser World. Most Rogue Trader ships are second-hand, battle-scarred, tired and worn ex-navy vessels but the Ambition is not. It's the only cruiser class that can be bought brand spanking new by Private parties in the Imperium and each one is unique and built to the customer's specifications. These exclusive ships, whilst still cruisers and deadly in their own right, are stately homes and status symbols. Some durability sacrifices have been made in order to make them the most opulent and luxurious ships on the market but for eccentric people like Rogue Traders, it's generally worth it.
**'''Conquest-Class Star Galleon:''' Built for the very first Rogue Traders on the orders of the Emperor himself, the Star Galleon is an ancient and noble design. Whilst not considered heavily armed by modern standards, they're still formidable opponents and yet as specialist exploration vessels they are able to operate independently for many years and can transport greater quantities than other Cruisers. In effect, it's a cruiser fused with a transport and looks fucking amazing.
**'''Murder:''' The predecessor to the Lunar. Differs by being keel-built, exchanging their torpedos for Lances and having more powerful macrobatteries. The majority that appear in modern 40k are Chaos-aligned, as the Imperials mothballed theirs in favor of the Lunar. A few carried lances as well as Macrobatteries, meaning they don't fit into any category. As with the Slaughter, it is unknown if Murder-class is their original name or they were renamed.

===[[Imperial Navy Light Cruiser|Light Cruiser]]===
Smaller than true cruisers, light cruisers are used in two ways. Either you use a fast, maneuverable light cruiser like the Dauntless to add some extra firepower to a scouting squadron or long-range patrol, or you use a pocket cruiser like the Voss light cruisers to add some heavy firepower and armor to a convoy, fleet, or base. The advantage of the light cruisers are that they're cheaper to build and operate than real cruisers. Another departure from real nomenclature. In real life, “light” cruisers were less armed and armored normal cruisers made to make up for losses, especially in America after Japan’s initial attack. After the industry fully turned to wartime manufacturing, the light cruisers’ changes were recinded and they were just normal cruisers again. However, with the introduction of heavy cruisers, the normal cruisers again were named “light” cruisers to avoid confusion. In 40k, however, light cruisers are very distinct and fill a unique niche. Like the Cruiser, they fit into a few base categories.
*'''Basic:''' Same as its larger sibling, a Jack of All Trades.
**'''Dauntless;''' The standard Light Cruiser of the Imperium; it's a Jack-of-all-Trades. You can't go wrong with the Dauntless even though other Light Cruisers may be better for certain tasks. Considered 'scouting' cruisers, these make up the bulk of Imperial Patrol Squadron leaders.
**'''Defender:''' A convoy escort variant of the Dauntless, with added dorsal weaponry.
**'''Endeavour;''' A 'heavy', Light Cruiser, designed as a stop-gap between the 'lighter' light cruisers and true cruisers. Whilst they can slug it out in a fleet fight, they can easily be overwhelmed because they simply aren't cruisers and don't have the equivalent fire-power or hull integrity. As an added titbit, most of Battlefleet Koronus' patrols consist of an Endeavour and a pair of frigates.
**'''Lathe-class Monitor-Cruiser;''' An Adeptus Mechanicus Light Cruiser designed around deep space exploration and extreme self-reliance. These ships, when properly outfitted, can operate for decades without returning to imperial space for resupply. These would make up the bulk of Explorator fleets.
**'''Secutor-class Monitor-Cruiser;''' An Adeptus Mechanicus Light Cruiser designed to excel at the art of war. Tougher than all of the other Light Cruisers and yet still more mobile than true Cruisers. Due to being designed from the ground up to be a Warship, this Light Cruiser is fitted with Cruiser sized Void Shield Generators.
**'''Siluria;''' Three-quarters the cost of the Endeavor, and about three-quarters the ship. Standard weapon batteries only, no fancy frills to speak of. Cheap and effective, at short range, to catch enemy torpedoes.
*'''Lance-boat:''' Also the same as the Cruiser version, though some have weak weapons batteries for better defence.
**'''Endurance;''' Light Cruiser with just enough guns to claim it has them, lance batteries and a couple of torpedoes. It's the lance half of a Lunar, nothing more.
*'''Carrier:''' More useful as a Light Cruiser, as it can act as backup for patrols.
**'''Enforcer:''' A carrier variant of the Dauntless. Designed to maintain control of rebellious planets via intimidation [[Grimdark|(and possible orbital bombardment)]]. Given one managed to stop the rebellion of an ''entire sub-sector'', its a shame the Imperium doesn't build more of them.
**'''Defiant;''' A carrier variant of the Endeavour. It's quite versatile (by virtue of being a carrier) and so has found a home in many Rogue Trader houses but unfortunately the Imperial Navy doesn't consider it as useful because they can't stand by themselves and require an escort. Due to being based off of the Endeavour, it's relatively well armoured for a Light Cruiser and that does help with its survivability.

===Ironclad===
8 kilometer long battering rams. No, really. Tyranids and Orks are busy taking notes.

===[[Imperial Navy Escort|Escort ships]]===
Escorts are the smallest armed vessels available to the Imperial Navy. These ships are normally assigned sector patrol duties or perform as escorts for much larger ships. In fleet engagements they will also act as scouts, ranging out in front of their armada to verify enemy ship numbers and locations. They are generally clasiffied as either frigates, or as destroyer ships.

====Frigates====
Ranging from about 1.4-2km long. They are used for all sorts of duties from convoy escorts to attack or patrol squadrons. Ironically named, as in real life Frigates were the same as Cruisers (which were not Ships of the Line).
*'''Basic:''' Laser batteries only, maybe some Torpedoes if you're lucky. Named after types of swords.
**'''Sword Frigate:''' The most common warship in the Imperial Navy, and one of the simplest. No torpedoes or lances to distract you here; a Sword puts two massive laser batteries behind a pointed armored prow and cuts into enemy formations like [[C.S Goto|a multi-laser through canon.]]
**'''Falchion Frigate:''' A new (245 years old) class of escort ship built by [[Forgeworld|Voss Prime]]. Slow as balls but still capable of firing torpedoes. While Cobras are used offensively in fleet actions, Falchion's are designed to be convoy escorts and stick close to larger warships to defend them from enemy escorts. Effectively a Voss-pattern Sword with torpedo tubes and one laser battery.
**'''Claymore Corvette:''' Designed entirely around escorting vulnerable transports and protecting them against light raiders in order to allow true Frigates to accompany more valuable ships such as Battleships, Battlecruisers and Cruisers. The Claymore Corvettes are easy to mass produce and maintain and are exceedingly common in the private sector, as they are simply a discount Sword.
**'''Turbulent Heavy Frigate:''' Heavy Naval Escorts; these things have comparable armour to cruisers. They're built to sally forth ahead of the main fleet and win skirmishes against enemy scouting forces and vanguard elements. They've garnered a reputation for being lucky; they've contributed to many glorious victories and survived catastrophes that other ship classes have not. Their only downside is that they have rather antiquated communication equipment, probably equipped for durability, not ease of use.
*'''Lance-boat:''' Rarer for Frigates, as they need a Prow slot to mount a Lance.
**'''Firestorm Frigate:''' A Sword-class frigate with a prow-mounted Lance replacing one laser battery. Gives the Sword some extra anti-ship punch that it dearly needs. It's also two hundred meters longer than the Sword-class as a result. The Navy does not like the Marines having them, for some reason.
**'''Thunderbolt Heavy Frigate:''' Not much information on this one, but implied to be a Lance version of the Turbulent, like how the Firestorm is the Lance version of the Sword.
**<s>[[Derp|Given the general naming scheme for Frigate classes is naming them after weapons (Claymore, Sword, Falchion, Gladius etc), the Firestorm would make more sense being called the ''Lance''-class due to its role.]]</s> It's pretty clear refits do not follow the same naming conventions.
*'''Ordnance-boat:''' Mostly upgunned Frigates. Can carry a mix of macrobatteries and small lances.
**'''Tempest Strike Frigate:''' Specialized Brawling frigate designed for devastating enemies at close range. Basically a Sword with a triple armoured prow and heavy short-range broadside batteries. They're often equipped with Assault Boats and Barracks for boarding actions.
**'''Havoc Merchant Raider:''' Small, yet fast raider sized vessels whose impressive firepower came at the expense of armor. Glass Cannons, in large squadrons these can easily overwhelm larger vessels by weight of fire.

====Destroyers====
The most common warship class. Their tasks range from scouting to shuttling VIPs or fighting in fleet engagements in large squadrons. Most pirates use these speedy, nimble vessels to prey upon transport ships.
*'''Basic:''' Usually mounts Prow Torpedoes and a Macrobattery.
**'''Cobra Destroyer:''' The PT-Boats of the Imperial Navy. Small, fast, and lightly armed, their one purpose in life is to fire shoals of torpedoes from 3-8 ship squadrons. A great part of the Imperium's military advantage (in fluff and [[Battlefleet Gothic|on the tabletop]]) comes from all the torpedoes they can fire at the enemy, and the Cobras are a big part of that.
**'''Infidel Raider:''' Was meant to replace the Cobra, but the plans [[Blood Ravens|were stolen]] by Chaos. Armed with Prow Torpedos and a Macrobattery like its predecessor, though some Chaos fleets upgrade them to Heavy Raiders by adding another Macrobattery.
**'''Iconoclast Destroyer:''' If there ever was an Guardsman of starships, the Iconoclast is it. A destroyer so shitty the Navy doesn't want it, the Iconoclast mounts 1-2 macrobatteries and is used by Rogue Traders, Chaos and Pirates. Notable for being one of the few ships to have a forward placed bridge, likely due to the smoke-stack like pylons along its spine.
*'''Torpedo-boat:''' Why waste space on pop guns?
**'''Viper Destroyer:''' Given GW's naming conventions, it was inevitable somebody would do this. Not to be confused with the Sloop below, this is a variant of the Cobra where the guns are replaced by torpedoes. Weak against escorts but deadly in numbers against capital ships. Use [[Boarding Torpedo|Boarding Torpedoes]] for hilarious results.
*'''Lance-boat:''' Rather rare among Raiders, as most use their Prow slots for Torpedoes.
**'''Apostate Heavy Raider:''' A variant of the Infidel. Somehow those heretics managed to shove a full sized Lance into a Dorsal slot, which only Light Cruiser and bigger can normally manage.
**'''Idolator Raider:''' Also known as the "WTF is this" ship, the Idolator is the lovechild of a Infidel, a Firestorm and Xenotech. Has a prow lance and a macrobattery.
*'''Other:''' Mostly weak scouts.
**'''Viper Scout Sloop:''' Smallest warp-capable ship in mass production. It is an exceedingly fast scout ship with ridiculously powerful realspace engines and high-tech auspex scanners. In support of Naval Operations these vessels would burn into enemy territory at high speed, collect as much information as possible and then warp back to friendly territory. Unfortunately they are so specialized that they can't do much else apart from that.
**'''Rudense "Class":''' A small ship designed post Gathering Storm to be as fast, heavily armed, and densely armoured as possible, which they do with aplomb. You may ask yourselves, why are they not used in more regular combat roles? Well, the answer is that they are a specialised orbital insertion ship - designed to get as close to the atmosphere of a heavily defended planet as possible, drop it's cargo of primaris marines into the top layer, and get out of there. Whilst this may seem too specialised to be practical, few enemies are ready for half a company of marines dropping in to their base unexpectedly. (Nb - the class hasn't been formally named yet but the only example of it thus far was named the Rudense).

===Aircraft===
As part of the reforms falling the Horus Heresy the Imperial army was not just split into regiments to insure that no one imperial army could be self sufficient if it fell to heresy or rebellion, the army was also split from it's air power which was given to the Imperial navy. Strictly speaking all atmospheric aircraft are also part of the Imperial Navy, with only [[Phantine Air Corps| few general exceptions]].
*'''[[Fighter]]:''' The fighter's main role is to stop enemy torpedoes and bombers before they can [[anal circumference|rip your flying cathedral multiple new assholes]]. Comes in different models like the [[Fury Interceptor]] or the Thunderbolt Fighter. The main difference is that some can enter a planet's atmosphere to dogfight and/or strafe ground targets where others are limited to space combat.
*'''Bomber:''' Basically reusable torpedoes. Come in different models like the [[Marauder Bomber]] and the [[Starhawk Bomber]], but again the main difference is that some can dip in a planet's atmosphere and drop bombs on ground-pounders where others are space-combat only.

===Armed Freighter (in the Battlefleet)===
Ships bought, borrowed or stolen and then armed in the misguided attempt to boost the strength of a fleet in desperate need of ships (instead of simply using the legio cybernetica to make robots to do the monotonous manual labor so 90% of the hundred thousand crew members can be spread out amongst a hundred more warships)

===Fire Ship===
A fancy name for a fuckheug bomb. A old, damaged or for whatever reason no longer usable ship is packed to the brim with explosives and flown straight into the heart of the enemy formation. Again, Orks are busy taking notes for their Roks. Contrary to what you might think from the Imperium, this is not a suicide assignment. A skeleton crew is used and supplied with plenty of escape pods/lifeboats. The crew evacuates and the ship detonates after they are far out of the danger zone. Some captains decide to go down with the fire ship anyway. Or they mindfuck some penitents to stay and guide it to the best point of detonation. The Imperium isn't short on criminals and/or desperate underclassmen/mutants.

===Non-Warp Capable Vessels===
Vessels incapable of interstellar travel. All but the most primitive Imperial planets have them.
*'''System Ships:''' Civilian ships that do all the civilian stuff like ferrying, mining and transport. As nobody would buy models of them, [[GW]] never bothered to flesh out their canon. If armed, they are dragooned into the System Defense Force during invasions.
*'''Defense Monitor:''' Essentially, a mobile gun emplacement in space. Slow and small, it diverts all its power into the battleship-sized gun it carries. Crewed by regular Imperial Navy personnel and used to augment existing defenses.
*'''System Defense Vessel:''' The primary unit of a System Defense Force aka the [[Planetary Defense Force|PDF]] in space. Nobody knows what they look like or even what capabilities they have. It is assumed they are lightly armed vessels usually used in police actions and customs enforcement. In times of invasion, they use hit and run tactics as best they can until they die.

===Logistic Vessels===
Ships used for the transportation of cargo or individuals. The majority of Imperial ships would fall into this category.

*'''Carrack-Class Transport Ship;''' A newer version of the Conquest Star Galleon. It's a hardy vessel that can defend itself quite well against raiders. The profile even looks like a Military Vessel so opponents who can't distinguish between Imperial Ships could be scared off.

*'''Goliath-Class Factory Ship;''' An Adeptus Mechanicus vessel designed to harvest plasma from Stars. These ships supply the fuel for the entirety of the Imperium. Other ships can be fitted with Plasma Scoops to top up their own tanks but this is the true fuel-harvesting-workhorse of the Imperium.

*'''Jericho-Class Pilgrim Vessel:''' Refinery ships that have been converted into personnel carriers, the majority of which will be transporting poor-er passengers. Can't really defend itself but usually not even worth the bother for pirates.

*'''Loki-Class Q Ship;''' Converted Cargo ships designed to sacrifice some space for added weaponry. They can serve as Convoy defence in a pinch and can surprise the odd pirate who may underestimate them.

*'''Orion-Class Star Clipper;''' Blockade runners through and through. They're designed to transport low-volume but high-quality goods, even through hostile space. Speed is the name of their game. Hell, these things can put some Eldar ships to shame.

*'''Universe-Class Mass Conveyor;''' Think Super-Tanker in space. It's the largest standardized Cargo hauler in the Imperium and is 12km long. It looks freaking awesome too.

*'''Vagabond-Class Merchant Trader;''' Rather small cargo vessel but extremely common. As if to assist with its 'commoner' theme, it makes you yawn just looking at it.

==Adeptus Mechanicus ships==
Being in charge of manufacturing the warships for the other departments of the Imperium, obviously the Adeptus Mechanicus would also have fleets of its own. The official Mechanicum body that constructs and operates spacecraft is known as the Basilikon Astra. Because the Quest for Knowledge can involve long & dangerous travels into unexplored space, it is important that they be heavily armed and armored, so the Adeptus Mechanicus ships generally are overall of higher quality than standard ships, with better tecnology, weapons, and shields. Though the total number of ships the Adeptus Mechanicus has at its disposal dispersed among its many forge worlds is far outnumbered by that of the Imperial Navy, it goes without saying that those responsible for all starship construction reserve for themselves among the most powerful and best-equipped warships encountered anywhere in the Imperium.

*'''[[Ark_Mechanicus|Ark Mechanicus:]]''' If battleships are literal void-traveling cities, then Ark Mechanicus are void-traveling factories or massive laboratories, with industrial capabilities rivaling that of many hive cities, with kilometre upon kilometre of manufactoria, refineries, crackling Plasma Reactors and laboratories, test ranges, chemical vats and gene-bays. This kind of battleships are incredibly large, nigh-mythical ships that are said to endlessly search the stars as part of the Adeptus Mechanicus Quest for Knowledge, being led by a Venerated Archmagos Explorator. An Ark Mechanicus is outfitted with the most powerful weapons available to the Imperium, generally having a balanced set of macro-cannons, lances, launch bays & a Nova Cannon; Because the search of STC into the unknown can be THAT dangerous.

*'''Adeptus Mechanicus Cruiser:''' Besides vanilla cruisers, the Mechanicus have its own original Cruisers & Light Cruisers, that have better equipment than Imperial Navy cruisers, many times they tend to have nova cannons and that they use servitor slaves instead of human slaves, and occasionally use auto-loaders. In resume, take Imperial Cruiser but quit the typical imperial armored prow, make it shinier, give it better weapons, and can put a nova cannon as a plus.

==Important Details==

===Crews===
''Navy crews are made up of officers, techpriests, slave drivers, and slaves.''

A bit of an over-simplification, but broadly true. Due to the Imperium's aversion to AI and Automation each ship needs at least thousands of people to man it. Whenever the crew count gets low, the Imperial Navy sets up fake strip clubs on a planet claiming "Free Hookers" to lure in unsuspecting men (and the occasional woman). Once a future crewman steps in, he's knocked out, bound, gagged, and taken to the ship, [[grimdark|where they'll slave away the rest of their soon-to-be-short existence]] doing everything needed to make flying through space and fighting in the void possible.

This includes dragging shells the size of houses into cannons while being whipped. Still, at least for the crew sex is allowed, in fact encouraged, if for no other reason than maintaining the crew complement. Seriously, whole fucking cities and civilizations arise from the more massive ships, every bit as intricate as a long lived Hive City. [https://www.youtube.com/watch?v=ax7wcShvrus Here is an idea of how it works, right up to the Roman armor, whips and beatings.] Oh and apparently besides whole civilizations, there are whole civilizations of mutants around too. They can more or less settle new worlds for da [[Emprah]] by simply disgorging their excess population, which the crew is probably all too happy to do.

One area where fluff [[Black Library|hasn't been consistent]] is in the uniform worn by Imperial Navy crewmen. Some sources suggest that uniforms are divided by segmentum of the Imperium, while others suggest that it is a sector-by-sector fashion choice. Given the scale the of the Imperium and the fact that Navy fleets are already identified by hull color, it's probably on a segmentum basis, but [[Games Workshop]] doesn't care enough to make a decision about it. For the ranks of the aforementioned shell draggers at the bottom of the naval hierarchy they'd wear a motley collection of their old civilian clothes and whatever they could scrounge up and sew together.

===Travel===
The ships of the [[Imperium]] travel through the [[Warp]] using what's called a warp drive to get to where they're going. However, this isn't your happy, fancy tunnel-of-light like in Star Wars, or everything-moves-fast Star Trek, it is an alternate dimension full of [[Chaos]]. In order to avoid being turned inside-out (think Event Horizon) and getting hentai-raped by every daemon in the warp, the ships rely on what is called the [[Gellar Field]] to keep the [[furries]], undesirables, and various other evil beings out of their ship when traveling through. The Baroque decorations are also implied in helping to ward off said daemons. They rely on a [[Navigator]] that uses the [[Empra]] as a beacon to safely navigate the Warp, hence the title "Navigator".

==Ranks in the Navy==
While the Imperial Navy uses a lot of the ranks in similar fashion to modern militaries, they invariably hold to a more archaic form and are not equivalent to modern day ranking systems. Particularly since it's quite clear that commissions in 40k can often be purchased rather than earned, and that a "Warrant" would most likely hold to the original term and be an "officer by appointment" rather than an enlisted grade. Though considering the immense variety of units within the Imperium, this may not necessarily be the case galaxy-wide, so all options are equally valid. Also, the ship commander will generally be referred to as Captain internally for the sake of simplicity, except in Astartes fleets where they are called shipmasters to avoid confusion regarding the actual rank of Captain in the Astartes.

===Officer Ranks===
*'''Lord-High Admiral of the Imperial Navy''' - This guy is a [[High Lords of Terra|High Lord]] and is the single dude responsible for the '''ENTIRE''' Imperial Navy, though likely he doesn't do much other than delegate to his subordinates and attend tedious High Lord meetings.
*'''Lord-High Admiral''' - There are five of these guys, one for each Segmentum. While they're probably never anywhere near the front lines they probably have more to do, since its their job to oversee the deployment of fleets and materials from sector to sector.
*'''Lord Admiral''' - The guy in charge of a sector fleet who gets direct command of vessels and formations. You see these guys in the fluff quite regularly when "key" worlds ''(like Armageddon)'' need defended or attacked.
*'''Solar Admiral''' - Often a ''terminal'' rank... no really. Occasionally regular Admirals who do good jobs can put themselves forward for promotion to this position, which needs to be approved by the Lord-High Admiral of their Segmentum, then the officer needs to travel to Terra be reviewed by the Lord-High Admiral of the Imperial Navy. Obviously this can take a very, ''VERY'' long time to approve. So they might often be [[Grimdark|dead before the paperwork gets rubber-stamped]]. If they do get approved they are likely to get promoted straight up to sector commander (see Lord Admiral) as a position will probably have opened up while he was waiting. More rarely, Solar Admirals can get sent on "detached duties" which is basically a license to do as they please with their independent fleets.
*'''High Admiral''' - Commands several group of naval fleets (e.g. Battlegroups), often the most senior Navy officer in a Crusade but the things these fucks usually do is just having snacks with their Imperial Guard counterparts and leaving the combat duties to their subordinate Admirals
*'''Admiral''' - Gets put in charge of a fleet and told to oversee some subsectors. He's usually the highest of the "front line" ranks and much of his time will be on active duty patrolling his assigned region.
*'''Vice Admiral''' - Fleets traditionally get split into three parts, with the highest Admiral taking up the portion containing the larger ships, while the "Vice" Admiral takes the "Vanguard" portion of faster moving ships.
*'''Rear Admiral''' - the third portion of a fleet would be the "Rearguard" and usually gets assigned to the youngest/least experienced Admiral in the fleet. His job is usually the quietest one as he gets the mop-up and repair duties.
*'''Commodore''' - an experienced Captain in command of a squadron of capital ships. It's traditionally only a temporary rank, as capital ships don't always get assigned to each other the same way that escorts do. But the realities of war often mean that ships stay together for extended periods, often well beyond the lifespans of generations of captains.
*'''Lord Captain''' - not actually a rank, but an honourific applied to Captains of detached vessels operating independently. The '''"Lord-"''' part implies that they operate with the full authority of the the Imperial Navy when they act so they can deal with outside organisations (like planetary governors, Space Marines or Imperial Guard) on relatively even footing. Sometimes also known by the more archaic term of "Flag-Captain", since as the commander of a detached vessel they figuratively carry their own flag.
*'''Captain''' The commander of a single capital ship or the lead starship in an escort squadron.
*'''Commander''' - Usually the commander of an escort vessel. Is also the ranking officer on board orbital space stations. It also gets used as the terminal rank amongst Pilots, since small attack craft all fall under the remit of the Navy; so a '''Wing Commander''' would get command over all pilots based on a single carrier.
*'''Lord Lieutenant''' - The second-in-command to captains of capital ships, bizarrely Commanders don't hold that role and hold their own positions. Thankfully because a chain of command exists in any military, despite a Wing Commander holding higher "actual" rank over a Lieutenant on a carrier vessel he would not hold any higher authority on that ship than his duties allow for.
*'''Lieutenant''' - a "working" rank. Either holds command over small system vessels or acts as second in command to Commanders of escorts, or as department heads on Capital ships. They are also Squadron leaders amongst pilots.
*'''Sub-Lieutenant / Ensign''' - Team leaders or attack craft pilots
*'''Midshipman''' - Apprentice officers who haven't passed any exams or earned any responsibility, they would exist below the Warrant Officers in terms of authority, despite holding a commission. Midshipmen are commissioned from Imperial Nobility as part of the [[Administratum|Imperial Tithe]] ''(which can mean virtually anyone gets the job if they send their useless heirs just to keep the best ones at home)'' but they are also assigned from the [[Schola Progenium]]. In addition, Midshipmen also may be taken on as a personal favour from the Captain of a vessel if he knows the family. This echoes the ancient real-world practice of young noblemen showing up while the vessel was in dock with a letter from their family and being granted a commission on the Captain's say-so.

===NCO Ranks===
*'''Ship Master''' - the most senior Warrant officer on board a starship, also quite possibly the busiest man on the starship. It's his job to maintain the logs, update stellar navigation charts, oversee ships stores and order supplies, and command a hangar deck if there is one. Basically he's the guy who knows the ship better than anyone. In real-world historical usage, this guy would have an authority equivalent to a Lieutenant on board a starship, and would "mess" ''(ie: occupy the same space)'' as the other officers do.
*'''Bosun''' - ''(Shorthand for Boatswain)'' The NCO directly responsible for all of the common crew members, including [[Commissar|maintaining discipline]]. Despite his position, his actual rank may vary depending upon the size of vessel or operational requirements, in practice it never really matters since he's unlikely to ever meet another Boatswain. ''(real-world Boatswains are typically petty officers or warrant officers, but could be of any rank. They held responsibility over all areas of the ship other than Engineering, which was left to the Chief Engineer, as if the bosun disciplined/executed/imprisoned a skilled crewman from that department the ship could be crippled because of it)''.
**Note that most Capital Ships, but not all Escort ships, may have an actual Naval [[Commissar]] on board in this role, tasked with maintaining discipline up to and [[Blam|including]] the Officer compliment.
*'''Chief Warrant Officer''' - Also called "Chief Petty Officer" on some vessels. Will often be given command of important ship sections ''(like Chief Engineers, helmsmen, or auspex control, as these are are critical to ongoing operation of a starship)''
*'''Warrant Officer''' - You'll find lots of guys of equivalent rank on a ship, in command of various operational sections keeping the ship running at all times:
**Masters of Ordnance - make certain that Torpedoes and Attack craft (if any) are fueled and maintained.
**Master Gunner - have responsibility over all of the weapons batteries through the Gun Captains and make ensure they are loaded and fired when required.
**Master-at-Arms - responsible for all "small" arms on board a starship, overseeing all Sergeants-at-Arms, as well as maintaining order over any barracked Guard regiments currently in transit.
**Master of the Vox - making sense out of the bazillions of messages that run through the bridge at any given moment both internally and externally ''(crews can get pretty massive, and a lot of traffic can come through at once)''.
**Steward - the guy who keeps everyone else well fed.
*'''Gun Captain''' - Funnily enough, the man in charge of a single gun crew. Makes sure that the weapon is taken care of, is reloaded quickly enough, and is accurate when asked to fire. All of that comes back to this guy.
*'''Sergeant-at-Arms''' - Man in charge of the weapons lockers and leader of boarding parties, as well as maintaining ship-board security. Usually they are transferred from [[Imperial Guard]] regiments so that they don't have any prior association with the crew.
*'''Armsmen''' - Crewmen trusted to carry weapons more than a standard issue Lasgun/Laspistol. They are not true soldiers as offensive boarding actions tend to be rare. So these guys still have their own regular responsibilities on board ship. Since they are trusted more, they have slightly more freedom to move around the vessel as well, though most Imperial employees really don't want the job, since it means they get scrutinised more, or they could end up beating up their buddies.
*'''Voidsmen''' - the lowest rank of crewman on board a Naval Starship above the [[Servitor]]s unless the Captain is cool with slavery. If they have a skill or a trade they may be referred to as '''Able Voidsmen''' which is an official rank that might require examinations. Additionally, if they show leadership qualities they might be promoted to '''Leading Voidsman''' and put in charge of work gangs and be considered for promotion to Warrant Officer if a position opens up.

==Notable Problems==
These are problems some have with the Imperial Navy and their fluff....

===General Logistical Problems===
The big problem that the Imperial Navy has is that it's the only organised navy in the galaxy that's trying to defend its massive amounts of space. To do this takes vast numbers of ships but rather thinly spread out. Given the problems of warp travel it's also extremely hard to reinforce friendly fleets under attack. The foes of the navy come essentially in two flavours; raiders who might just manage to scrape together a few converted transports (building even escort-sized ships is a huge undertaking, akin to building damn near the entire American Navy combined from iron ore and making it fly) which take an escort squadron to murder, and huge organized invasion fleets that take a whole fleet to fight. These combine together to mean that outside of fleet bases and important strategic worlds there is nowhere in the Imperium that is actually well-defended. At best a fleet has to be formed and sent out and they could arrive months later. Travel takes a lot of time, and out in the void it can be extremely hard to know what you are actually fighting against, especially since the enemy tend to kill anyone who tries to look at them. So when there's a large enemy force that you absolutely must fight (not fighting is much preferable) you don't just band together whoever was within shouting distance of the flagship and go murdering, you pull together every single vessel in the sector and hope to the Emperor it's enough to do the job.

TL,DR: Acquiring a force sucks when command thinks paperwork and red tape are forms of worship and maintenance thinks the toilet needs a prayer before it is unclogged.

Warships genuinely are vast things and obscenely expensive and risking them at all in major actions is not something anyone does lightly. Each cruiser is larger and more complex than a fully-kitted titan legion. These things are MASSIVE. In the BFG book there's a fluff story of a cruiser being built at a shipyard that orbits a primitive world. The entire population of the planet were given over to mining the resources needed to build one single cruiser. It took them eleven years to mine the ore. Sure, that's a primitive world, but if you think about it that makes carving out the rocks for it the largest single project ever engaged upon without mechanization. If you add together all seven wonders of the world you aren't even close to the pile of rock we're talking about. So these things are a big fucking investment and the high lords really don't like risking them without a really good reason (<s>makes you questioning why they wouldn't build 20 smaller ships instead</s> ship sizes don’t work that way; 20 smaller ships against something capable of killing fifty ships that size is stupid so you build the one large ship so it lasts long enough to be a real threat, that said sacrificing escort and cruiser construction to a slightly smaller number to produce more raiders and destroyers to hunt enemy raiders and target vulnerable enemy populations would be a good idea).

So if you ever wondered why the Navy doesn't get more action, now you know. By the time the big, awesome ships get on the scene the invasion already probably finished and the bad guys moved on. Then you nuke the shit out of them from orbit or drop millions of poor bastards into the meat grinder. Far better idea all round. It's the reason that the enemy, even nutters like Chaos, don't fight in the void without reason. On the ground it's just a scrap, and maybe you win or maybe you don't. If you lose in the void then your campaign on the surface is dead. No reinforcements, no support and a massive constant orbital bombardment to kill everyone left (which sometimes doesn't happen, because, you know, <s>plot armour</s> shields, enemy surface-to-space weapons, don’t want to destroy your own territory when you can send mooks to reclaim it, etc.). That tends to mean fleets hover around and not fighting, one ensuring the other can't directly interfere with the surface war. This is actually an excellent and realistic explanation for why there is significant ground warfare in 40k. Also, ground-based defenses, mobile theater-shields, etc. are common. So, attacking a planet worth anything is like attacking a planet-sized Death Star without the super-weapon. Your ground forces taking out shields and anti-space batteries is critical to achieving anything. But, by that point, most of the enemy is dead and the survivors have either moved to the next defended region or got so stuck-in with your dudes that you can't shoot without killing your own army. Unless you worship Khorne, in which case you really couldn't care less who you kill, even yourself.

So, the navies of the galaxy ultimately get pushed down into either raiders, escorts against raiders, raider-hunters, or babysitting and logistical duty for groundpounders. Which of course brings back the question of why the Navy has such a desire to get more interceptors and bombers for ship-to-ship combat when they rarely engage in combat in the first place and the attack craft are insufficient. Could be to weaken the enemy ships' ability to shoot at the surface, but by the point they would have a target it would have (as stated) gone to a new defended location or whatever else, defeating the point of sending attack craft to weaken the enemy ships' offensive power. They won't shoot at each other, and they can't shoot at the surface (or at least can't shoot anything worth shooting at). In exchange for packing in so many attack craft into hangars designed for countless atmospheric air support fighters and bombers, the Imperial Guard has to die in radically greater numbers than they have any need to since they have limited anti-air capabilities and all of their enemies have no problem sending massive swarms of fighters and bombers at them. That is without even getting to engage the enemy on the ground and not counting the countless soldiers killed as the transports are shot to pieces due to their escorts commonly ditching them to go after obvious bait tactics.

Thus the rumor that the Navy has no balls. But who needs balls when you have a nova cannon sized dick and eighteen dice worth of fire power.

===Ship Size===
No one is quite sure how big the ships really are. One story claims the Retribution-Class is a mere 3 kilometers long, while another says it is 9 kilometers and up to 20 kilometers.

Your best bet is Rogue Trader, although going by those figures, anything bigger than a cruiser has an average density around that of hydrogen... From a helpful poster on [http://www.heresy-online.net/forums/showthread.php?t=63267&page=2 Heresy-Online] we have this:

For the most accurate scale, look towards the Battlefleet Koronus Expansion, as it is more a stat/rule book than a story. That and previous consensi, as well as cross referencing with the Horus Heresy rulebooks by Forge World (which places Battleships at 8-12km) place Cruisers just above 5 kms, and Battleships in the mid 8s. Please note that most ships above the size of 8ish kilometers are either a unique modified/purpose built flagship or a ship of a small class that is not in widespread calculations. For a sense of scale the largest warship in the world is currently the US Navy's Ford Class Aircraft Carrier measuring in at 337 meters long or 0.337km making the USS Ford the size of a cannon. They have guns literally the length of an Aircraft carrier!

Ultimately, direct numbers are likely useless. The lance turrets have been described as the size of cities and given the size of an Imperial or even a modern city...also, there are about 75 ships in a Sector Fleet. A sector is one thousand cubic lightyears and there are about a thousand sectors in the Imperium. Which means logically those ships should be incredibly massive and easily ten or even a hundred times larger than the size numbers given in fluff given the size and industrial might and manpower of the Imperium.

*Transports and other Attack Craft, typically rated for atmospheric operation; also includes ships designed to be boarding torpedoes.
**<1 kilometer. That's the small ones, there are super transports in 40k as well. (A [[thunderhawk]] would go here).
*Escorts are "small" ships, like the Cobra, designed to flank foes and operate in squads.
**1-2 kilometers.
**Heavy Frigates
**Frigates
**Corvettes
**Destroyers
**Freighters
*Light Cruiser, a smaller Cruiser.
**3-5 kilometers.
*Cruiser, the standard fighting vessel; every Imperial fleet has them.
**5-6 Kilometers.
*Battle Cruiser, a beefed up Cruiser; generally more 'modern' than a Grand Cruiser.
**6-7 kilometers.
*Grand Cruiser; pocket-sized Battleship, very old.
**7-8 kilometers.
*Battleship; the biggest of the lot, simply put.
**8-12 kilometers.
**Battleships
**Fleet Carriers

The Horus Heresy novel "Know No Fear" had this to say about ship sizes, taken from [http://archive.foolz.us/tg/thread/22848349/ /tg/] who quoted it from the book and written here is just the lengths and names of the ships, for simplicity and space:

*Macragge’s Honour. Twenty-six kilometers - Flagship
*Spirit of Konor. Seventeen kilometers - Battleship
*Antrodamicus. Twelve kilometers - Grand Cruiser
*Antipathy. Nine kilometers - Cruiser (note that the book said it had "six thousand lives" on board, which would be an absurdly small crew for its size by 40k or even 21st century standards - Cruisers normally have 85-95 thousand crew in 40k, and that's for normal sized ones, not double length ones like this one. But this is a Horus Heresy ship, so perhaps it's automation was much better then a later 40k ship)
*Aegis of Occluda. Seven kilometers - Class unknown
*Gladius. Four kilometers - Escort
*Then there is the Abyss-class created by Lorgar that is said to match the Phalanx in size. He made three of them.

===Weapon Effects===
If the weapons can annihilate a continent, why can't it destroy a mere hive? Because different writers don't talk to each other that's why. Also shields maybe.

Alternate take: Sure these weapons can destroy continents, but generally speaking why would the Imperial Navy want to bombard a probably Imperial Hive? Another thing to consider is that while Imperial warships are capable of *BLAM*-ing a planet, it requires a lot of ships firing either specialized planet-killing ordnance or just bombarding round the clock. One virus bomb/Cyclonic torpedo/lance shot would do comparatively little damage. But it does make you think about how powerful those void shields must be.

Another take: Something to keep in mind is the different size of ships and thus cannon barrels. A Retribution-class battleship is a lot bigger than a Mars-class battlecruiser is a lot bigger than a Turbulent-class heavy frigate, just to name a few. Different ships have different weapons.

Another Alternate take : The heresy novels elaborate a little on little on the practicalities of Orbital bombardment as a battlefield weapon. Whilst it is occasionally used tactically and reserved as a strategic level weapon, it requires utterly pinpoint accuracy (targeting being off by a millimetre in orbit could result in a shot being kilometres off on the ground) which is only possible when orbit is completely uncontested. It's use during land battles is the VERY definition of Danger Close and often a dead giveaway to the enemy, as allied forces have to withdraw kilometres away before ordering a bombardment, letting an enemy force bunker down or get out the way. Ships are also very easy targets for anti-orbital weapons during bombardment and the effect of a starship hulk hitting a planet you're fighting for is not something to be risked.

Alternate alternate take of an alternate take take: Hives are designed to withstand bombardment from orbit while firing back with enough power to make enemy ships stay away. This is the main reason why massive ground engagements happen (and there are theater shields available, too). For example, the Rock of the Dark Angels survive Caliban being essentially turned into its component atoms via mass bombardment. Also, the previuos "Another Alternate take" directly above this one is right. Now combine that take with this one and really the only way to take an enemy position is to get off your ass and do it yourself the manly way.

Alternated take because alternate takes on alternate takes don't take what it takes: most weapons are jackshit useless against a planet with atmosphere and magnetosphere. Nova cannon shots, plasma bursts and lance batteries are distorted by magnetic fields, macrobattery shots burn up in dense atmosphere, just like torpedoes and most void-faring attack craft.
To fire effectively the ships either have to come CLOSER into low orbit (being exposed to oversized cannons and missile launchers that can be seen around every major spaceport and hive city) and risk being burst open like a pinata, or are forced to just shit bombs from high orbit, being absolutely horrible at aiming.

===Lack of Balls===
It is well-known that most Imperial Navy Officers don't have em.

An Imperial Navy fleet is most effective when Inquisitors take it over. [[Exterminatus|See Here]].

===Carrier Hate===

Back in M36, the Imperial Navy fought a lowkey civil war over fleet doctrine in Segmentum Tempestus known as the Gareox Incident. A cabal of chaos worshipers worked their way high enough in the navy to start designing ships that were ready-built to turn traitor, most of which were carriers. The battlefleet eventually figured out something was off and the result was a giant carriers vs battleships fight that went down the way the Battle off Samar would have if the Japs hadn't been scared shitless by three destroyers. The surviving carriers went openly traitor and since then building new carriers has been borderline heresy so far as the navy is concerned. They don’t hate carriers, but many Imperial ships are basically battlestars, making carriers a pointless waste of resources. Attack craft are mostly used to weaken enemy firepower, shoot down torpedoes and enemy fighters and bombers and boarders, and finish off crippled enemy ships. On their own, they’re largely useless for actually defeating enemy ships. The main reason aircraft are so effective against navies in WW2 and modern navies is that they can use momentum for bombs and missiles to strike hard from above in order to penetrate decks. Space has no such option and every attack from any angle is similar to a torpedo plane attack run from the Second World War. Which is why Starhawk Bombers are basically just torpedoes. However, carriers are useful and accepted, just not useful enough to bother building from scratch and so carriers are almost always either repurposed wrecks of other ships or mothballed carriers being deployed where more attack craft are needed. This almost pointlessness also means carriers are looked down on as barely worth calling support ships.

==Music of the Imperial Navy==
Not to be outdone by the Imperial Guard (as well as to compensate for their aforementioned lack of balls), the Imperial Navy has begun collecting music to either be blared on loudspeakers when not in active use, or in the case of battleship command decks, played live by orchestra. the first four are taken from [[Battlefleet Gothic Armada|Battlefleet Gothic Armada.]]

The '''Imperial Navy''' is one of the main branches of the [[Imperium of Man|Imperial]] military in [[Warhammer 40,000]] (although very little of the Navy actually appears in the tabletop game). They are also one of the main factions in the beloved spin-off game [[Battlefleet Gothic]].

Unlike the [[Imperial Guard]], who get killed in the <s>thousands</s> <s>millions</s> billions every day, the Imperial Navy rarely suffers that many casualties. This is because, unlike the [[lasgun|flashlight]] used by Guardsmen, the main weapon of the Navy is a giant, heavily-armed, heavily-armored battleship that puts other races' spaceships to shame (well, except [[Necrons]]). These ships are also [[Awesome|massive, flying, Gothic cathedrals]].

Depending on how you look at it (and who you're looking at), the officers of the Navy are either wealthy cowards or badass gentlemen. In either case, their ships have crews numbering the hundreds of thousands or even millions (we're not kidding when we say that each ship has its own language(s) and culture(s)), since the Imperial Navy doesn't understand how auto-loaders work, so loading a gun requires thousands of slaves running on treadmills. Of course, this might be the fault of [[Adeptus Mechanicus|a certain other branch of the Imperium, who, coincidentally, ''do'' have working auto-loaders on their ships]]. In any case, [[Grimdark|the Imperium has found it cheaper and ''more effective'' to use manpower because they have ''that many people'' to throw at even the tiniest of problems.]] Except that the cost of hundreds of thousands or even millions of chain-gangs adds up over centuries and millennia whereas maintenance for the machinery would basically amount to "apply oil while chanting". Of course, for a major officer, most days simply require him to press a button and blow something up, then go back to drinking his tea. Oh, and ''maybe'' scramble the ground-support flyers, if he's feeling charitable that day.

Note that, back in the [[Great Crusade]], the Imperial Guard and Imperial Navy were one and the same, operating under the far-less-badass name of "Imperial Army." However, thanks to the [[Horus Heresy]], the two got split up, so that a single military commander couldn't control too many forces; a Guard commander isn't able to get off any given planet without the Navy, and the Navy isn't able to conduct wars (and, you know, occupy territory) without the Guard. You'd think that this enforced mutual co-dependence would make them collaborate, but [[grimdark|of course]], despite how much they need each other, the two bicker constantly, which, in fact, may be the reason for all the [[fail|stupidity]] the 40k universe is saddled with, at least on the military front.

==Types of Ships==
The Imperial Navy has four types of ships they hide their cowardly asses in. The main ships are battleships, cruisers, escorts, and fighters
Each ship can also be classified by its weaponry, and role in the battlefleet:
*'''Basic:''' Jack of All Trades ships, due to having multiples weapons types, and not being specialized into any. Lunar class cruisers are the prime example, having macrobateries, lances & torpedoes.
*'''Lance-boats:''' Ships that focus into Lance weaponry, used for long-range focused attacks, especially against small ships & unshielded ones. Rarer as they have a weakness to Void Shields and require better drives due to the power requirements of the lances.
*'''Ordnance-boat:''' Opposite of the Lance-boat, replaces Lances with more Macrobatteries, focusing mostly into medium & short range brawls against enemy ships. Usually this is because they need extra power due to mounting a Nova Cannon or having power-hungry macrobatteries such as Plasma Cannons.
*'''Carrier:''' The red-haired stepchild of the Navy. Replaces the Lances with Launch Bays and is disliked by most Admirals due to the stigma against Attack Craft, although it is because the Traitors & Chaos pawns focused on raiding & striking fast, so with enemy fleets focused on long range attack (Lances, laser, and attack craft)plus Chaos likes them more because they can fill the bays with Assault Boats, the Imperial Navy might have got that stigma of seeing too many Chaos carriers raiding & pillaging imperial planets & so started dislike them. Some Carriers are also made from wrecked cruisers of other types, in which case damaged broadside weapons are ripped out and replaced by launch bays.
*'''Torpedo-boat:''' Originally an experiment for escort ships to overrun enemy vessel crews using boarding torpedoes, it was doomed to failure as the targets were either too nimble or too big. The Imperial Navy kept a few as Missile Destroyers.

===[[Imperial Navy Battleship|Battleship]]===
Supposedly rare, but every Grand Marshal and High Admiral has at least one and often several or even dozens to hide in because GW is completely and hopelessly inconsistent with fleet sizes, though as of late it seems that GW is leaning towards big fleets and big armies when it gives numbers. Bonus points if that coward is also Chaos. The biggest heaviest hitters available, these things are like actual medieval cathedrals in that the grandchildren of the workers who start building them get to live to see their completion. Fuckheug, lots (and lots, and lots) of guns and most can deploy fighters and bombers.
*'''Ordnance-boats:'''
**'''Retribution:''' Packing all gun batteries, the ship can devastate an entire continent in one broadside, but for some reason cannot destroy a hive city or fort with [[void shields]] - [[What|or in some cases, ones without any shields at all]]; either that or GW was just pulling another [[Derp|Michael Bay]] out of their asses again since, they have no idea how [[Herp|consistency works, let alone basic physics.]] Of course, considering the Dark Angels fortress-monastery and the huge chunk of land surrounding it survived the bombardment which turned Caliban into a bunch of space dust, it is perfectly reasonable that something that merely glasses half a continent would not destroy a void shielded city or other major fortification. If anything, this provides a degree of insight into why land battles in 40k are so massive in the first place. Because orbital artillery doesn't have many targets of opportunity it is actually capable of exploiting without tearing the planet to pieces.
**'''Invincible:''' An interesting class, dubbed a 'fast battleship', these were designed to chase down xenos and chaos raiders, and then use them to make the vast, empty tracts of space more interesting by filling it with their enemies' debris fields. This type of battleship combines the firepower of a ''Retribution'' with the speed of a ''Dauntless''. The problem with this is the general incompetence of Imperial tacticians. It looks exactly like a ''Retribution'' and has the guns to match, so it must be one, right? NO. They excelled at the role they were designed for, but throw them into gunfights against dedicated battleships, and these things tended to come apart easier than wet cardboard, earning them the nickname 'Kisher's Kombustibles' and the scorn of many admirals. Admirals who ignored the fact that the reports detailing the introduction of the ship and how to best use it (it's tactics also included in the Tactica Imperialis) explicitly state not to use it on a gun-line and that it is for fast-ship interdiction. The ship's Commissars must be particularly incompetent to let this slide as in the Guard the generals would be executed quickly for such incompetence. Of course, these are also the Commissars who do nothing when troop transports' escorts frequently run off to fight while the transports lose a significant percentage of their ships. Perhaps if they would actually enforce their orders to stay with the transports, the Imperium would have won most of the campaigns it has lost. Given that they still often win even with a fraction of their beginning ground forces actually managing to make landfall. [[Grimdark|Because they have THAT many men to throw at the enemy.]]
***Much like the Chalice-class of Battlecruisers, the Invincibles are a big reference to the real life Battlecruisers of World War 1, especially with the term "Kisher's Kombustibles" (real life Battlecruisers were referred to as "Fisher's Combustibles") and the fact that three blew up in a single battle (referencing Jutland).
*'''Lance-boat:'''
**'''Apocalypse:''' One of the oldest ship designs (predating the ''Retribution'', which is also one of the oldest ship designs), this ship packs a lot of [[lances]] and a [[Nova Cannon]]. Good for taking out lots of smaller sized ships with massed lance fire. It's also described in fluff as being able to cripple anything up to a cruiser with a single, concentrated broadside. They're fairly rare, since the Imperium doesn't know how to build them anymore, and the ones still operating are so old, their weapons systems have degraded permanently, forcing them to fire their lances at only a fraction of their full power. Shares all the disadvantages of a ''Gothic''-class cruiser.
***Despite the fluff stating that the Apocalypse and Oberon classes are unique in that they lack figure-heads, the artwork and [[Crunch|models]] [[Derp|give them one anyway.]]
**'''Victory:''' Possibly an attempt to recreate the ''Apocalypse'' class, the ''Victory'' is basically a ''Retribution'' with a bunch of lances replacing its broadside cannons, and a Nova Cannon instead of torpedoes. Has the range that fluff states the ''Apocalypses'' once had, but lacks the same level of firepower. Effective at sniping, and hilarious when used against escort heavy fleets.
**'''Desolator:''' A ridiculously old design. Designed to emphasize range and carries Torpedos, Broadside Lances and Dorsal Macrobatteries. Like most keel-built ships, the Desolators ended up mothballed or went traitor.
*'''Carrier:'''
**'''Emperor:''' The "standard" battleship of the 40k 'verse, the ship has multiple fighter decks and weapons batteries. Unfortunately, most commanders like to use this ship as a hideout, causing the lack of sufficient air support in the ground wars even though the Navy's atmospheric aircraft are completely different from its much bigger space based strike craft. Tabletop-wise, its status as the official battleship of Battlefleet Gothic doesn't stop it from losing carrier duels against the Chaos equivalent.
***Ironically, the idea of the Emperor being the standard battleship conflicts with the fluff about the Navy hating Carriers. Go figure. Except it doesnt. Because the Imperial Navy isnt fond of carrier ships, but that doesnt mean they dont use them; So if you were an imperial admiral, would you choose to get multiple smaller carriers, at the cost of having less ship-of-the-line on your fleet? Or would you instead get a 8+ kilometer battleship with four city-sized hangar bays, having higher detection, and being capable of helping your fleet & any warzone in multiple ways (Not just void warfare, but also ground support in planet invasions, or logistical support) without the need of going too close to the enemy? Its no wonder the Emperor Class is so popular & useful in the Imperial Navy, looking at this way, in reality, the Emperor class goes well precisely on the conventional Imperial doctrine because of this reason. Despite the (idiotic) distaste Admirals have for strike craft, they will use still use them out of simple utility and they figure they might as well get something that can do more at the same time.
**'''Nemesis:''' The super-carrier of the Imperial Navy. It has SIX flight decks (the size of towns or small cities, each), more than any other ship in the galaxy. But because of Rule of Cool, it is incredibly rare since the Navy captains prefer to get up close broadside their enemies, or actually rather because all of the ships in this class were just ships modified from Emperor class ships in one particular war, because they were damaged or otherwise. Naturally, the Navy never considers making them based on the Invincible instead (the Invincible was mass-produced).
**'''Desecrator:''' The carrier variant of the Desolator. Replaces half the Broadside Lances with Landing Bays. Shared the same fate as its sister class and is now only seen in Chaos fleets. Traitorous despite its clearly pious and Emperor-loving name.
**'''Despoiler:''' Oh boy, where do we start? The Despoiler-class came about after the cogboys discovered plans for a carrier on Barbarus. The catch? Well, Barbarus is the former homeworld of the [[Death Guard]], and the plans were for the same class of ship that the [[Terminus Est]] is a part of. Showing a complete lack of common sense, the Imperial Navy decided to build ships of this class, only for them all to go traitor due to the class's inherent [[Gellar Field]] flaws. [[Fail|Oops]]. The Despoilers at first don't appear to be that unique, as they have Dorsal Lances and Broadside Landing Bays and Weapons Batteries. Their difference is that, like the Terminus Est, they managed to have a Prow Landing Bay as well.
***Despite being a new class, GW fucked up their fluff and had [[Rogal Dorn]] disappear aboard a Despoiler, [[What|5000 years before the class was created]]. Note this class was actually already named "Despoiler-class" by the Imperium. Yet, they were ''surprised'' the things went traitor. Wow. Also, after fixing the Gellar Field problem, the Imperium still decided not to build more, which was stupid since there was no longer a reason not to. I get not wanting to chance it, but beggars can't be choosers.
*'''Other:'''
**'''[[Gloriana-class_Battleship|Gloriana]]:''' Massive, terrifying and capable of decimating entire fleets on their own, these were the personal flagships of the Primarchs during the Great Crusade. Very few, if any, are still around in the Imperium in M41, though a few such as Horus's flagship ''[[Vengeful Spirit]]'' are still tooling around inside the Eye of Terror. Because they were dickheads, the [[Alpha Legion]] had two, creatively named the ''Alpha'' and the ''Beta''. Interestingly, the Ultramarines have one, the ''[[Macragge's Honour]]'', but didn't [[derp|fucking]] use it, the whole fucking time until [[Roboute Guilliman]] returned. It shows up again in ''Dark Imperium,'' with the Smurfs having stolen it back from the Red Corsairs, which at least is fucking funny even if it makes no sense. The Imperial Fist had the ''Eternal Crusader'', but it was never their flagship since the [[Phalanx]] is so much better, so [[Rogal Dorn]] gave it to the [[Black Templars]] in the [[Second Founding]]. The Emperor is known to have had at least one, called the ''Bucephalus'' (also the name of the horse of Alexander the Great... coincidence?), which he ditched after upgrading to an enormous golden space palace called ''Imperator Somnium'' for the sole purpose of flying him back to Terra to retire. Wait, did Emps just see the Phalanx and decide to build his own bigger better version?! [[Eldrad|DICK]].
**'''Oberon:''' The mixed-breed bastard of the Imperial Navy. It has [[lances]], fighter bays, and weapon batteries. Its a powerful ship... <s>when fighting foes half its size</s> "Newer" fluff says the Oberon is rare, but a complete success in making a ship capable of killing anything it comes across, alone. Unfortunately, fluff also says a ridiculously low number of these (apparently) powerful ships were made (like, 3 or so). Then again: only four Iowa class battleships ships were built (technically 6, but 2 were scrapped before completion), and we know HOW to build them. It makes sense in a way. Attack craft can cripple an enemy's main weapons and engines and likely ultimately damage the power transfer from generators to void shields. Combined with macro-batteries hammering away and the enemy's weakened ability to maintain its shields would cause them to drop much quicker than usual. Then the city-sized lance-batteries rip the enemy in half. If used against enemy escorts to support attacks on large enemy ships like battleships and grandcruisers, this would work extremely well to the point an Oberon would likely become a priority target for enemy ships.

===[[Imperial Navy Grand Cruiser|Grand Cruiser]]===
Only slightly weaker and less powerful than Battleships, Grand Cruisers were the weird middle-child of actual Line Ships (that really were the mainstay of the fleet back then) and Cruisers in the ancient Imperium. Built primarily with autonomy in mind, those were reserved for the most daring expeditions in the uncharted regions, conducted both by Imperial Army and Rogue Traders. Nowadays most of them run on archeotech that is barely understood and hard to repair with current Imperial knowledge. These grand ships are often used as flagships in lieu of extremely rare Battleships. Basically, they are the quintessential Battlecruisers; tougher and deadlier than Cruisers and yet more mobile than Battleships.
*'''Basic'''
**'''Vengeance/Furious:''' The granddaddy of "modern" Imperial warships. The ''Vengeance'' was the winner of a GW-sponsored ship design contest, and was originally known as the ''Furious''. Highlights include heavy shielding and armour (though lacking the prow armour of later designs), as well as both lances and long range weapons batteries, making this the sniper of the Imperium's Grand Cruisers.
**'''Repulsive:''' Originally named the Corinus Class, before being renamed after many fell to Chaos by an overly literal Mechanicum designation. Whilst the Repulsive Grand Cruisers are exceedingly maneuverable heavy warships (and therefore exceedingly useful because they can fill a hole in the Imperial tactical lineup), they are considered a cursed class due to the majority of them falling to chaos, [[Fail|which unfortunately was the result of experimental warp drives which occasionally interfered with the Gellar Field (OMGWTFBBQTIME)]]. Only the Emperor knows what kind of complete moron would deploy ships equipped with that. The ones that remain in Imperial control are kept mothballed in reserve fleets and segmentum fortresses (imagine giant glass boxes with 'In Case of Emergency, Break Glass' signs). It doesn't say anything about their warp drives being swapped out for something that isn't shitty or perhaps a completed and no longer experimental version of their own. Not that you want AdMechs tear off your head for tinkering with their sacred templates, on the other hand.
*'''Ordnance-boat:'''
**'''Avenger:''' The short range brawler of the Imperium's Grand Cruisers, it's a ''Vengeance'' with only macrobatteries (kilometres of Macrobattery broadsides). Intended to break the line of battle like Nelson's ships at Trafalgar, while suffering from the lack of an armored prow. Unfortunately line-breaking is quite a dangerous role for any ship, even a Grand Cruiser that excels at doing it, and so not many exist in the 41st Millennium. Those that have survived are known for being exceedingly reliable and faithful; it takes a lot of damage or mistreatment to cause these noble vessels to give trouble. If you spoke with members of the Imperium (both members of the public and the navy), this is the vessel they would think of if you asked them about Grand Cruisers. Now, if only the Imperium realized a slower but more heavily armored and shielded ship would fare better in its role.
*'''Lance-boat:'''
**'''Executor:''' The sniper of the Vengeances, the Executor replaces its Broadside Macrobatteries with even more Lances. Unfortunately, the last remaining Imperial Executors decided to act retarded and chase a fleet into the Eye of Terror, meaning that all of the ships are chaos aligned now.
*'''Carrier:'''
**'''Exorcist:''' A ''Vengeance'' that has carrier bays in place of lances. Useful in providing carrier support to any Imperial fleet. As a bonus, being Grand Cuisers mean they can outrun anything except battleships to save their vulnerable carrier self while their attack craft are away. Originally designed for extended operations alone on the Frontiers of Imperial Space, either on Patrol or by exploring into the unknown, the Exorcist developed quite a reputation for 'boldly going where no man has gone before'. Whilst not many remain in Imperial Service due to maintenance difficulties, they still find use in the hands of Rogue Traders who need vessels capable of long cruises and of defending themselves against anything they might encounter. So much for maintenance difficulties.
**'''Retaliator:''' A mix of a Repulsive and a Vengeance, but as a Carrier. Has Lances, Launch Bays and Macrobatteries on its Broadsides. Unfortunately, it has the Repulsive's tendency to go traitor.

===[[Imperial Navy Battlecruiser|Battlecruiser]]===
What do you do when you forget how to maintain an entire category of heavy warships? You build a new bunch of heavy warships, with simpler technology.

Battlecruisers are basically upgunned cruisers, with more weapons (usually adding dorsal weapons and some armor), and are intended to fill the gap between true battleships, which are rare, and normal cruisers, which tend to die really easily to the ancient Chaos cruisers and grand cruisers. Battle cruisers were tried in real life as some way to combine battleship firepower or armor and cruiser speed. They did not always work, and much like reality these things have their share of problems. Chaos operates their own versions known as Heavy Cruisers. In real life, the accepted successful form of a battlecruiser is between a heavy cruiser and a battleship; it can kill anything it can catch and it can outrun anything that can kill it (usually only an enemy battleship). After its teething years it was generally a good and effective form of combat when used intelligently.
*'''Basic:'''
**'''Armageddon Battlecruiser:''' An upgraded variant of the Lunar Class Cruiser (YAY! ANOTHER ONE!). A rather new innovation, the Armageddon class is basically made up from recovered Lunar Class Hulks that have been extensively repaired and then retrofitted with more armour and more weapons. The base hull was never designed to cope with all this extra equipment (and the extra crew to man said equipment) and so it has problems operating independently for long periods of time. This isn’t really a problem, though, since they wouldn’t be operating away from a fleet anyway. Though reinforcing its frame to handle the added mass would be a smart thing to do to save immensely in future maintenace costs over the centuries. Battlefleets won't say no to them because more guns = better! These ships are extremely powerful and live up to their name. Somehow, though, the Imperium never went “Hey guys, this thing kicks the shit out of everyone, let’s upgrade all Lunar-class ships to Armageddon-class and make a new class to accomodate the new crew and equipment.” Or someone did and was turned into a servitor...
**'''Hellfire Heavy Cruiser:''' An upgunned Murder-class. Has the same issues as the Armageddon, slow as fuck and has power and supply issues. [[What|Also, lacks Void Shields]]. Most mutinied and joined Chaos, which decided to use them for some reason.
*'''Ordnance-boat:'''
**'''Overlord Battlecruiser:''' The Classic Imperial Battlecruiser. Using the standard Imperial doctrine of - Macrobatteries, Lances and Torpedoes, the Overlord has become the most effective Battlecruiser simply because it really complements standard Imperial Navy Tactics. As an added bonus, its simplicity of design makes it easier to produce and one can be built within a decade. The only negative (if you can call it a negative), is that it's not really useful for anything except war.
**'''Chalice Battlecruiser:''' A fast heavy cruiser. Unique to the Calixis sector and an exceedingly new design, the Chalice was conceived as a Battlecruiser that could either out-run or out-manoeuvre anything it can't kill. Which means it was conceived to be a plain ‘ol normal battlecruiser. Whilst good in theory, unfortunately, speed came at the cost of armour and durability and so whilst these vessels punch hard, they can't take as many hits as other cruisers. In addition, it carries an experimental plasma drive layout, which while boosting power efficiency, also makes it rather vulnerable to lighting up like a roman candle. Imperial Propaganda is currently trying to cover up their failings and is lauding them as the Poster-ships of the Calixis Sector and therefore a lot of people think they're the 'Best Battlecruisers Eva!'. If they would just use a normal plasma drive and make the whole ship bigger, it would be fast enough, armored enough, and even better armed. Unfortunately, not being stupid is heresy in Calixis.
***The idea of a ship that can "either out-run or out-manoeuvre anything it can't kill" that turns out to be really poor at taking hits was the original design of real life Battlecruisers, which although being up-gunned Cruisers (which are the equivalent of Frigates IRL, not Ships of the Line), were used as discount Battleships at Jutland were they turned out to lack the armour required for a proper fight. Thus, if the Imperials were smart, they would be using the Chalice as a commerce raider, not a ship of the line.
**** Actually, they were not bad at taking hits, they were better at it than heavy cruisers. They just sucked at taking hits from battleships like everybody else on the planet. Real life battlecruisers (after their early screw up designs) were made only a little smaller than battleships which allowed them to have greater armor and firepower and speed than heavy cruisers and were even fast enough to outrun battleships at the cost of significantly lower firepower and armor than the only slightly larger battleships (which caused things like the Jutland kablooie). They had the whole package. In reality, the larger the ship the faster it is in navies (broadly speaking, in dense fluids the longer the vehicle is relative to its cross-section, the easier it is to go fast), sci-fi just is made by ignorrants. Battlecruisers fell out of favor shortly after they were perfected for the same reason battleships and heavy cruisers did: the carrier. That said, they were indeed usually used as commerce raiders. But that is true for all ships. Navies exist to destroy enemy commerce shipping and to transport armies. The only reason fleets engage each other is because both sides defend their own shipping and seek out enemy fleets to pre-emptively destroy to protect said shipping and transports. In 40k, it could be said that the Invincible-class is the closest thing the Imperium has to an equivalent to a real life battlecruiser.
**'''Long Serpent Battlecruiser:''' A true success story, this is what the ''Chalice'' wishes it was. Taking a battlecruiser's armour and firepower, and giving it the engine suite of a battleship, this thing can kick the shit out of anything short of a grand cruiser or battleship, while being able to keep up with raiders. It's only real flaw is that when one is taken out, it has a better than average chance of rupturing its warp drive. As a result, the names of ''Long Serpents'' that have been destroyed are usually accompanied by those of allied ships that were too close. Which is somewhat odd since the reasoning is that the Long Serpent also has a battleship's warp core (who knows why, it isn't big enough to need it). Given the small difference in size between this ship and other "normal" cruisers which are the mainstays of the fleet, the Imperium could just choose to use a smaller warp core suitable for this ship's size and focus on mass-producing the Long Serpent to replace basically every other class of ship except battleships , Cobras, and carriers. Fewer would be made but, unlike video games, swarming a capital ship with escorts does not work at all. The escorts are slaughtered and the capital ship like this one is left unharmed. But doing this would require common sense, which is [[Heresy]]. Like properly using the Invincible-class must be.
**'''Mercury Battlecruiser:''' Another fast Battlecruiser. It's a cruiser with a Battleships's engines. Nothing more.
**'''Hades Heavy Cruiser:''' A long-ranged brawler. Carries Broadside Macrobatteries and Dorsal and Prow Lances. Got phased out like most keel-built designs, but Chaos still uses them.
*'''Lance-boats:'''
**'''Acheron Heavy Cruiser:''' Designed to test new Lances and Macrobatteries. The Imperials only built one, which went traitor. Carries Broadside and Dorsal Lances with Prow Macrobatteries.
*'''Carriers:'''
**'''Mars Battlecruiser:''' In a word - Mediocre. Some Imperials say it's versatile due to its diverse weapons loadout but in reality it makes it an awkward duckling to use. The Nova Cannon and Launch bays would be good on a ship holding back and harassing enemies at range and yet it has Macrobatteries and Lances which are great for brawling. So if you sit back and harass or go in and brawl, you're wasting half your ship. The Imperial Navy never really got on with it either and so it has gone out of production on most Forge-Worlds. Which is a shame because if they would replace the macrobatteries and lances with larger, long-range lances, and a great number of small, short range weapons batteries for fighter support and self-defense respectively, this would be a great ship in any fleet. It's nova cannon clears a hole in the enemy escort screen, the attack craft rush through to wreck the weapons and engines of light capital ships while long-range lances assist other Imperial ships in slaughtering targets of opportunity. The destroyed enemy light capital ships leaves all the other big ships vulnerable to mass, concentrated torpedo attack from friendly ships. Attack craft return to the fight to tear up the no-doubt seriously damaged enemy big ships and lances win the day. Then just send in friendly light capital ships with attack craft support to finish off the surviving escorts. That would almost make this ship into a sort of miniature "I Win" button. Almost. Especially in a squadron of two, as they could assist each other against any opponents that slip through to them with their combined, close-range firepower, lances, and whatever attack craft they kept back for defense ripping the enemy weapons and engines apart to let the close-range macrobatteries have fun.
**'''Dominion Battlecruiser:''' Basically a fixed Mars, some tech priest got it in their head that, maybe, it'd make more sense to replace the Macrobatteries with Lance Batteries instead, making it a dedicated support ship, harrassing enemy ships at range whilst the big guns go out and fight. Apparently not that successful, a number were used at the Battle for Maccrage (Of course the fucking Smurfs get them) against the tyranids, though apparently they all got fucked up and have been in drydock since, which is why up until now no-one's seen them.
**'''Styx Heavy Cruiser:''' A pure carrier. Has Broadside Launch Bays, Dorsal Lances and and Prow Macrobatteries. For some reason the Imperial phased it out for the Mars, so only Chaos uses them now.
**'''Hecate Heavy Cruiser:''' An attempt to replace the Styx. Swaps out some of the Launch Bays for Macrobatteries. Believed to have an inherent design flaw that made them go traitor, so they were decommissioned.

===[[Imperial Navy Cruiser|Cruiser]]===
Cruisers are the bread and butter of the Imperial Navy. Much larger than escorts and light cruisers, but less rare than battleships, cruisers are what the Imperial Navy (and Chaos and Xenos) use to fight their campaigns across the stars. Thus far, all Imperial Cruisers have been shown to utilize the same hull-type: a squat armored prow in front, capable of mounting a prow-mounted weapon system, and a big bunch of engines in the back, with baroque and Gothic architecture in-between. Most cruisers can effectively be placed in four categories:
*'''Basic:'''
**'''Lunar:''' The Lunar. You've heard so much about it and now you want to know what it makes it the standard Imperial Cruiser. First of all, it's one of the oldest designs still in use by the Imperium and is so easy to build that even less advanced worlds can produce them. They're quite versatile due to their weapons loadout (a balanced build of Macrobatteries, Lances and Torpedoes) and make up the backbone of Battlefleets throughout the entire Imperium. This is the cruiser against which all other cruisers are measured.
**'''Emasculator:''' Considered a failure by the Imperium at large, Emasculators have the same basic load-out as the Lunar, but are keel-built, lacking the armored prow and replacing the torpedo tubes with more weapons batteries. This means they require different tactics to a Lunar, using their speed and longer ranged weapons to pound ships from a distance. As this fits with Chaos tactics more than Imperials. most of them ended up as traitors. [[/d/|The name Emasculator is due to them being seen mostly as Slaaneshi ships, their original name is unknown.]] The fact the Imperium keeps trying new ships built on the normally Chaos style hulls implies that usually it must work out just fine since otherwise it would have been banned by now. So, there are probably many cool looking keel-based Imperial ship classes floating around we'll never catch wind of ever.
**'''Slaughter:''' A special type of Cruiser, the Slaughter-class has a more powerful drive called the Scartix Engine Coil, but lacks prow weapons. Armed with short ranged, but powerful lances and macrobatteries, the Slaughter is designed to get in close, blast away and retreat. Unfortunately, the Imperium can't build them anymore because one went traitor and destroyed the plans for the Scartix Coil. It is unknown if they were always called the Slaughter-class or were renamed when most went traitor. Considering the usual lack of intelligence in the Imperium's leadership, it was probably called something worse, like the "Traitor-class" or something and then the Imperium wss shocked when they lived up to it. Really, would you be surprised if the Imperium did that?
**'''Inferno:''' A earlier counterpart to the Carnage-class, carrying more lances in exchange for some Macrobatteries. Had the same difficulties as the Carnage and was mothballed, though a few went renegade beforehand. Rare example of the Imperium learning its lesson. Still too stupid to realize that using cheaper-after-a-few-centuries-than-manual-labor auto-loaders would've fixed the problem for both ships.
*'''Lance-boat:'''
**'''Gothic:''' Another variant of the Lunar Class, the Gothic is designed as a heavy Lance gunship. Due to the amount of Lance Weaponry it carries, it can easily deal with ships of its own size or larger but often does require an escort or a partner to strip enemy void shields first in order to use its own weaponry to the maximum effect. When supported and used correctly, Gothic Cruisers are the most efficient way to deal with enemy capital ships.
*'''Ordnance-boat:'''
**'''Dominator:''' A variant of the Lunar Class, the Dominator is designed primarily for planetary bombardment and assault. Not generally used in fleet actions even though it can provide support with its Nova Cannon when necessary. After one Dominator fucked over a Chaos Cruiser with said Nova Cannon during the Gothic War, the Navy took note and started making more Dominators. [[Awesome|Additionally, another Dominator came close to destroying the Terminus Est (''aka the toughest Battleship in the galaxy''), before being destroyed.]] The Dominator possesses the same armament as the Retribution-class battleship but lacks the range of one. This is fine, though, since it's meant to get close to the enemy like most Imperial ships anyway. Basically, if you get in range of this thing, ''you're going to die''.
*** From Lexicanum 40K: "Captain Straden of the Depth of Fury defended the shrine world of Kathur to the death, and came very close to destroying the Death Guard ship Terminus Est. As it was, he and his crew vaporised several of its decks and destroyed scores of escort ships before finally succumbing. Ironically, no Imperial souls survived to tell the tale."
**'''Tyrant:''' The Tyrant was originally intended as a stand-off vessel; it would stay at long range and bombard enemies from afar with superfired plasma weaponry. Unfortunately, due to design compromises where it mixed both short range and long range weaponry to save on power, it wasn't really deadly enough at long range to do its job. Therefore the Imperial Navy is trying to replace the short range weapons with ancient Long-range weaponry (that doesn't use a lot of power) recovered from Space Hulks or Renegade Ships. The Hull itself is a rather effective design and so the Tyrant has become very popular with Rogue Traders who generally replace all of the Plasma Weaponry in order to have more power available compared with other cruisers.
**'''Relentless/Carnage:''' Another attempt at a fleet support ship with Plasma weapons, the Relentless ended up with technical difficulties and, when these were overcome, [[Heresy|most ships ended up turning traitor]] [[Fail|(including the lead ship of the class)]]. [[Tzeentch|This is theorised to be due to something wrong with the geometry of the ship's design]], as the Relentless-class is keel built, like most older ships (This also means the Relentless lacks an armored prow and torpedo tubes, carrying more plasma batteries instead). The tendency of these ships to turn to Chaos, along with changing tactics, led to the class being renamed the Carnage-class and mothballed in favor of the Tyrant-class, though their speed means they suit Chaos tactics famously.
*'''Carrier:'''
**'''Dictator:''' A Carrier retrofit of extremely damaged Lunar Class Cruisers. If a Lunar class has its lance weaponry destroyed, it's quicker, easier and cheaper to replace those with heavy launch bays for strike craft. This makes it quite versatile and able to deal with virtually all situations and interestingly enough, makes it more effective than the original Lunar Class at everything except fighting as a ship of the line. Unfortunately, the Lunar Class is designed for fighting as a ship of the line, so Admirals dislike Dictators.
**'''Jupiter:''' A kitbashed design, converted from other classes of cruiser that have been heavily damaged in battle. By stripping out all the damaged components and replacing them with launch bays, you get a pretty sturdy carrier. Just don't let the enemy get anywhere near it. Apparently the Imperium doesn't build these normally at all, likely because they are absolutely shit at defending themselves from other Cruisers.
**'''Devastation:''' Deviating from the standard Carrier design, the Devastation-class carries Lances instead of Macrobatteries. Mostly turned traitor or mothballed, as they lack armored prows and torpedos; and are keel-built. Chaos likes them, as they can pack them with mutants and sit back to spam assault boats and lances at anything that looks at them funny.
*'''Other:''' Various other cruiser types exist, but are rarer.
**'''Ambition:''' Custom-made Cruisers for the exceedingly affluent - it's the Rolls Royce of the Cruiser World. Most Rogue Trader ships are second-hand, battle-scarred, tired and worn ex-navy vessels but the Ambition is not. It's the only cruiser class that can be bought brand spanking new by Private parties in the Imperium and each one is unique and built to the customer's specifications. These exclusive ships, whilst still cruisers and deadly in their own right, are stately homes and status symbols. Some durability sacrifices have been made in order to make them the most opulent and luxurious ships on the market but for eccentric people like Rogue Traders, it's generally worth it.
**'''Conquest-Class Star Galleon:''' Built for the very first Rogue Traders on the orders of the Emperor himself, the Star Galleon is an ancient and noble design. Whilst not considered heavily armed by modern standards, they're still formidable opponents and yet as specialist exploration vessels they are able to operate independently for many years and can transport greater quantities than other Cruisers. In effect, it's a cruiser fused with a transport and looks fucking amazing.
**'''Murder:''' The predecessor to the Lunar. Differs by being keel-built, exchanging their torpedos for Lances and having more powerful macrobatteries. The majority that appear in modern 40k are Chaos-aligned, as the Imperials mothballed theirs in favor of the Lunar. A few carried lances as well as Macrobatteries, meaning they don't fit into any category. As with the Slaughter, it is unknown if Murder-class is their original name or they were renamed.

===[[Imperial Navy Light Cruiser|Light Cruiser]]===
Smaller than true cruisers, light cruisers are used in two ways. Either you use a fast, maneuverable light cruiser like the Dauntless to add some extra firepower to a scouting squadron or long-range patrol, or you use a pocket cruiser like the Voss light cruisers to add some heavy firepower and armor to a convoy, fleet, or base. The advantage of the light cruisers are that they're cheaper to build and operate than real cruisers. Another departure from real nomenclature. In real life, “light” cruisers were less armed and armored normal cruisers made to make up for losses, especially in America after Japan’s initial attack. After the industry fully turned to wartime manufacturing, the light cruisers’ changes were recinded and they were just normal cruisers again. However, with the introduction of heavy cruisers, the normal cruisers again were named “light” cruisers to avoid confusion. In 40k, however, light cruisers are very distinct and fill a unique niche. Like the Cruiser, they fit into a few base categories.
*'''Basic:''' Same as its larger sibling, a Jack of All Trades.
**'''Dauntless;''' The standard Light Cruiser of the Imperium; it's a Jack-of-all-Trades. You can't go wrong with the Dauntless even though other Light Cruisers may be better for certain tasks. Considered 'scouting' cruisers, these make up the bulk of Imperial Patrol Squadron leaders.
**'''Defender:''' A convoy escort variant of the Dauntless, with added dorsal weaponry.
**'''Endeavour;''' A 'heavy', Light Cruiser, designed as a stop-gap between the 'lighter' light cruisers and true cruisers. Whilst they can slug it out in a fleet fight, they can easily be overwhelmed because they simply aren't cruisers and don't have the equivalent fire-power or hull integrity. As an added titbit, most of Battlefleet Koronus' patrols consist of an Endeavour and a pair of frigates.
**'''Lathe-class Monitor-Cruiser;''' An Adeptus Mechanicus Light Cruiser designed around deep space exploration and extreme self-reliance. These ships, when properly outfitted, can operate for decades without returning to imperial space for resupply. These would make up the bulk of Explorator fleets.
**'''Secutor-class Monitor-Cruiser;''' An Adeptus Mechanicus Light Cruiser designed to excel at the art of war. Tougher than all of the other Light Cruisers and yet still more mobile than true Cruisers. Due to being designed from the ground up to be a Warship, this Light Cruiser is fitted with Cruiser sized Void Shield Generators.
**'''Siluria;''' Three-quarters the cost of the Endeavor, and about three-quarters the ship. Standard weapon batteries only, no fancy frills to speak of. Cheap and effective, at short range, to catch enemy torpedoes.
*'''Lance-boat:''' Also the same as the Cruiser version, though some have weak weapons batteries for better defence.
**'''Endurance;''' Light Cruiser with just enough guns to claim it has them, lance batteries and a couple of torpedoes. It's the lance half of a Lunar, nothing more.
*'''Carrier:''' More useful as a Light Cruiser, as it can act as backup for patrols.
**'''Enforcer:''' A carrier variant of the Dauntless. Designed to maintain control of rebellious planets via intimidation [[Grimdark|(and possible orbital bombardment)]]. Given one managed to stop the rebellion of an ''entire sub-sector'', its a shame the Imperium doesn't build more of them.
**'''Defiant;''' A carrier variant of the Endeavour. It's quite versatile (by virtue of being a carrier) and so has found a home in many Rogue Trader houses but unfortunately the Imperial Navy doesn't consider it as useful because they can't stand by themselves and require an escort. Due to being based off of the Endeavour, it's relatively well armoured for a Light Cruiser and that does help with its survivability.

===Ironclad===
8 kilometer long battering rams. No, really. Tyranids and Orks are busy taking notes.

===[[Imperial Navy Escort|Escort ships]]===
Escorts are the smallest armed vessels available to the Imperial Navy. These ships are normally assigned sector patrol duties or perform as escorts for much larger ships. In fleet engagements they will also act as scouts, ranging out in front of their armada to verify enemy ship numbers and locations. They are generally clasiffied as either frigates, or as destroyer ships.

====Frigates====
Ranging from about 1.4-2km long. They are used for all sorts of duties from convoy escorts to attack or patrol squadrons. Ironically named, as in real life Frigates were the same as Cruisers (which were not Ships of the Line).
*'''Basic:''' Laser batteries only, maybe some Torpedoes if you're lucky. Named after types of swords.
**'''Sword Frigate:''' The most common warship in the Imperial Navy, and one of the simplest. No torpedoes or lances to distract you here; a Sword puts two massive laser batteries behind a pointed armored prow and cuts into enemy formations like [[C.S Goto|a multi-laser through canon.]]
**'''Falchion Frigate:''' A new (245 years old) class of escort ship built by [[Forgeworld|Voss Prime]]. Slow as balls but still capable of firing torpedoes. While Cobras are used offensively in fleet actions, Falchion's are designed to be convoy escorts and stick close to larger warships to defend them from enemy escorts. Effectively a Voss-pattern Sword with torpedo tubes and one laser battery.
**'''Claymore Corvette:''' Designed entirely around escorting vulnerable transports and protecting them against light raiders in order to allow true Frigates to accompany more valuable ships such as Battleships, Battlecruisers and Cruisers. The Claymore Corvettes are easy to mass produce and maintain and are exceedingly common in the private sector, as they are simply a discount Sword.
**'''Turbulent Heavy Frigate:''' Heavy Naval Escorts; these things have comparable armour to cruisers. They're built to sally forth ahead of the main fleet and win skirmishes against enemy scouting forces and vanguard elements. They've garnered a reputation for being lucky; they've contributed to many glorious victories and survived catastrophes that other ship classes have not. Their only downside is that they have rather antiquated communication equipment, probably equipped for durability, not ease of use.
*'''Lance-boat:''' Rarer for Frigates, as they need a Prow slot to mount a Lance.
**'''Firestorm Frigate:''' A Sword-class frigate with a prow-mounted Lance replacing one laser battery. Gives the Sword some extra anti-ship punch that it dearly needs. It's also two hundred meters longer than the Sword-class as a result. The Navy does not like the Marines having them, for some reason.
**'''Thunderbolt Heavy Frigate:''' Not much information on this one, but implied to be a Lance version of the Turbulent, like how the Firestorm is the Lance version of the Sword.
**<s>[[Derp|Given the general naming scheme for Frigate classes is naming them after weapons (Claymore, Sword, Falchion, Gladius etc), the Firestorm would make more sense being called the ''Lance''-class due to its role.]]</s> It's pretty clear refits do not follow the same naming conventions.
*'''Ordnance-boat:''' Mostly upgunned Frigates. Can carry a mix of macrobatteries and small lances.
**'''Tempest Strike Frigate:''' Specialized Brawling frigate designed for devastating enemies at close range. Basically a Sword with a triple armoured prow and heavy short-range broadside batteries. They're often equipped with Assault Boats and Barracks for boarding actions.
**'''Havoc Merchant Raider:''' Small, yet fast raider sized vessels whose impressive firepower came at the expense of armor. Glass Cannons, in large squadrons these can easily overwhelm larger vessels by weight of fire.

====Destroyers====
The most common warship class. Their tasks range from scouting to shuttling VIPs or fighting in fleet engagements in large squadrons. Most pirates use these speedy, nimble vessels to prey upon transport ships.
*'''Basic:''' Usually mounts Prow Torpedoes and a Macrobattery.
**'''Cobra Destroyer:''' The PT-Boats of the Imperial Navy. Small, fast, and lightly armed, their one purpose in life is to fire shoals of torpedoes from 3-8 ship squadrons. A great part of the Imperium's military advantage (in fluff and [[Battlefleet Gothic|on the tabletop]]) comes from all the torpedoes they can fire at the enemy, and the Cobras are a big part of that.
**'''Infidel Raider:''' Was meant to replace the Cobra, but the plans [[Blood Ravens|were stolen]] by Chaos. Armed with Prow Torpedos and a Macrobattery like its predecessor, though some Chaos fleets upgrade them to Heavy Raiders by adding another Macrobattery.
**'''Iconoclast Destroyer:''' If there ever was an Guardsman of starships, the Iconoclast is it. A destroyer so shitty the Navy doesn't want it, the Iconoclast mounts 1-2 macrobatteries and is used by Rogue Traders, Chaos and Pirates. Notable for being one of the few ships to have a forward placed bridge, likely due to the smoke-stack like pylons along its spine.
*'''Torpedo-boat:''' Why waste space on pop guns?
**'''Viper Destroyer:''' Given GW's naming conventions, it was inevitable somebody would do this. Not to be confused with the Sloop below, this is a variant of the Cobra where the guns are replaced by torpedoes. Weak against escorts but deadly in numbers against capital ships. Use [[Boarding Torpedo|Boarding Torpedoes]] for hilarious results.
*'''Lance-boat:''' Rather rare among Raiders, as most use their Prow slots for Torpedoes.
**'''Apostate Heavy Raider:''' A variant of the Infidel. Somehow those heretics managed to shove a full sized Lance into a Dorsal slot, which only Light Cruiser and bigger can normally manage.
**'''Idolator Raider:''' Also known as the "WTF is this" ship, the Idolator is the lovechild of a Infidel, a Firestorm and Xenotech. Has a prow lance and a macrobattery.
*'''Other:''' Mostly weak scouts.
**'''Viper Scout Sloop:''' Smallest warp-capable ship in mass production. It is an exceedingly fast scout ship with ridiculously powerful realspace engines and high-tech auspex scanners. In support of Naval Operations these vessels would burn into enemy territory at high speed, collect as much information as possible and then warp back to friendly territory. Unfortunately they are so specialized that they can't do much else apart from that.
**'''Rudense "Class":''' A small ship designed post Gathering Storm to be as fast, heavily armed, and densely armoured as possible, which they do with aplomb. You may ask yourselves, why are they not used in more regular combat roles? Well, the answer is that they are a specialised orbital insertion ship - designed to get as close to the atmosphere of a heavily defended planet as possible, drop it's cargo of primaris marines into the top layer, and get out of there. Whilst this may seem too specialised to be practical, few enemies are ready for half a company of marines dropping in to their base unexpectedly. (Nb - the class hasn't been formally named yet but the only example of it thus far was named the Rudense).

===Aircraft===
As part of the reforms falling the Horus Heresy the Imperial army was not just split into regiments to insure that no one imperial army could be self sufficient if it fell to heresy or rebellion, the army was also split from it's air power which was given to the Imperial navy. Strictly speaking all atmospheric aircraft are also part of the Imperial Navy, with only [[Phantine Air Corps| few general exceptions]].
*'''[[Fighter]]:''' The fighter's main role is to stop enemy torpedoes and bombers before they can [[anal circumference|rip your flying cathedral multiple new assholes]]. Comes in different models like the [[Fury Interceptor]] or the Thunderbolt Fighter. The main difference is that some can enter a planet's atmosphere to dogfight and/or strafe ground targets where others are limited to space combat.
*'''Bomber:''' Basically reusable torpedoes. Come in different models like the [[Marauder Bomber]] and the [[Starhawk Bomber]], but again the main difference is that some can dip in a planet's atmosphere and drop bombs on ground-pounders where others are space-combat only.

===Armed Freighter (in the Battlefleet)===
Ships bought, borrowed or stolen and then armed in the misguided attempt to boost the strength of a fleet in desperate need of ships (instead of simply using the legio cybernetica to make robots to do the monotonous manual labor so 90% of the hundred thousand crew members can be spread out amongst a hundred more warships)

===Fire Ship===
A fancy name for a fuckheug bomb. A old, damaged or for whatever reason no longer usable ship is packed to the brim with explosives and flown straight into the heart of the enemy formation. Again, Orks are busy taking notes for their Roks. Contrary to what you might think from the Imperium, this is not a suicide assignment. A skeleton crew is used and supplied with plenty of escape pods/lifeboats. The crew evacuates and the ship detonates after they are far out of the danger zone. Some captains decide to go down with the fire ship anyway. Or they mindfuck some penitents to stay and guide it to the best point of detonation. The Imperium isn't short on criminals and/or desperate underclassmen/mutants.

===Non-Warp Capable Vessels===
Vessels incapable of interstellar travel. All but the most primitive Imperial planets have them.
*'''System Ships:''' Civilian ships that do all the civilian stuff like ferrying, mining and transport. As nobody would buy models of them, [[GW]] never bothered to flesh out their canon. If armed, they are dragooned into the System Defense Force during invasions.
*'''Defense Monitor:''' Essentially, a mobile gun emplacement in space. Slow and small, it diverts all its power into the battleship-sized gun it carries. Crewed by regular Imperial Navy personnel and used to augment existing defenses.
*'''System Defense Vessel:''' The primary unit of a System Defense Force aka the [[Planetary Defense Force|PDF]] in space. Nobody knows what they look like or even what capabilities they have. It is assumed they are lightly armed vessels usually used in police actions and customs enforcement. In times of invasion, they use hit and run tactics as best they can until they die.

===Logistic Vessels===
Ships used for the transportation of cargo or individuals. The majority of Imperial ships would fall into this category.

*'''Carrack-Class Transport Ship;''' A newer version of the Conquest Star Galleon. It's a hardy vessel that can defend itself quite well against raiders. The profile even looks like a Military Vessel so opponents who can't distinguish between Imperial Ships could be scared off.

*'''Goliath-Class Factory Ship;''' An Adeptus Mechanicus vessel designed to harvest plasma from Stars. These ships supply the fuel for the entirety of the Imperium. Other ships can be fitted with Plasma Scoops to top up their own tanks but this is the true fuel-harvesting-workhorse of the Imperium.

*'''Jericho-Class Pilgrim Vessel:''' Refinery ships that have been converted into personnel carriers, the majority of which will be transporting poor-er passengers. Can't really defend itself but usually not even worth the bother for pirates.

*'''Loki-Class Q Ship;''' Converted Cargo ships designed to sacrifice some space for added weaponry. They can serve as Convoy defence in a pinch and can surprise the odd pirate who may underestimate them.

*'''Orion-Class Star Clipper;''' Blockade runners through and through. They're designed to transport low-volume but high-quality goods, even through hostile space. Speed is the name of their game. Hell, these things can put some Eldar ships to shame.

*'''Universe-Class Mass Conveyor;''' Think Super-Tanker in space. It's the largest standardized Cargo hauler in the Imperium and is 12km long. It looks freaking awesome too.

*'''Vagabond-Class Merchant Trader;''' Rather small cargo vessel but extremely common. As if to assist with its 'commoner' theme, it makes you yawn just looking at it.

==Adeptus Mechanicus ships==
Being in charge of manufacturing the warships for the other departments of the Imperium, obviously the Adeptus Mechanicus would also have fleets of its own. The official Mechanicum body that constructs and operates spacecraft is known as the Basilikon Astra. Because the Quest for Knowledge can involve long & dangerous travels into unexplored space, it is important that they be heavily armed and armored, so the Adeptus Mechanicus ships generally are overall of higher quality than standard ships, with better tecnology, weapons, and shields. Though the total number of ships the Adeptus Mechanicus has at its disposal dispersed among its many forge worlds is far outnumbered by that of the Imperial Navy, it goes without saying that those responsible for all starship construction reserve for themselves among the most powerful and best-equipped warships encountered anywhere in the Imperium.

*'''[[Ark_Mechanicus|Ark Mechanicus:]]''' If battleships are literal void-traveling cities, then Ark Mechanicus are void-traveling factories or massive laboratories, with industrial capabilities rivaling that of many hive cities, with kilometre upon kilometre of manufactoria, refineries, crackling Plasma Reactors and laboratories, test ranges, chemical vats and gene-bays. This kind of battleships are incredibly large, nigh-mythical ships that are said to endlessly search the stars as part of the Adeptus Mechanicus Quest for Knowledge, being led by a Venerated Archmagos Explorator. An Ark Mechanicus is outfitted with the most powerful weapons available to the Imperium, generally having a balanced set of macro-cannons, lances, launch bays & a Nova Cannon; Because the search of STC into the unknown can be THAT dangerous.

*'''Adeptus Mechanicus Cruiser:''' Besides vanilla cruisers, the Mechanicus have its own original Cruisers & Light Cruisers, that have better equipment than Imperial Navy cruisers, many times they tend to have nova cannons and that they use servitor slaves instead of human slaves, and occasionally use auto-loaders. In resume, take Imperial Cruiser but quit the typical imperial armored prow, make it shinier, give it better weapons, and can put a nova cannon as a plus.

==Important Details==

===Crews===
''Navy crews are made up of officers, techpriests, slave drivers, and slaves.''

A bit of an over-simplification, but broadly true. Due to the Imperium's aversion to AI and Automation each ship needs at least thousands of people to man it. Whenever the crew count gets low, the Imperial Navy sets up fake strip clubs on a planet claiming "Free Hookers" to lure in unsuspecting men (and the occasional woman). Once a future crewman steps in, he's knocked out, bound, gagged, and taken to the ship, [[grimdark|where they'll slave away the rest of their soon-to-be-short existence]] doing everything needed to make flying through space and fighting in the void possible.

This includes dragging shells the size of houses into cannons while being whipped. Still, at least for the crew sex is allowed, in fact encouraged, if for no other reason than maintaining the crew complement. Seriously, whole fucking cities and civilizations arise from the more massive ships, every bit as intricate as a long lived Hive City. [https://www.youtube.com/watch?v=ax7wcShvrus Here is an idea of how it works, right up to the Roman armor, whips and beatings.] Oh and apparently besides whole civilizations, there are whole civilizations of mutants around too. They can more or less settle new worlds for da [[Emprah]] by simply disgorging their excess population, which the crew is probably all too happy to do.

One area where fluff [[Black Library|hasn't been consistent]] is in the uniform worn by Imperial Navy crewmen. Some sources suggest that uniforms are divided by segmentum of the Imperium, while others suggest that it is a sector-by-sector fashion choice. Given the scale the of the Imperium and the fact that Navy fleets are already identified by hull color, it's probably on a segmentum basis, but [[Games Workshop]] doesn't care enough to make a decision about it. For the ranks of the aforementioned shell draggers at the bottom of the naval hierarchy they'd wear a motley collection of their old civilian clothes and whatever they could scrounge up and sew together.

===Travel===
The ships of the [[Imperium]] travel through the [[Warp]] using what's called a warp drive to get to where they're going. However, this isn't your happy, fancy tunnel-of-light like in Star Wars, or everything-moves-fast Star Trek, it is an alternate dimension full of [[Chaos]]. In order to avoid being turned inside-out (think Event Horizon) and getting hentai-raped by every daemon in the warp, the ships rely on what is called the [[Gellar Field]] to keep the [[furries]], undesirables, and various other evil beings out of their ship when traveling through. The Baroque decorations are also implied in helping to ward off said daemons. They rely on a [[Navigator]] that uses the [[Empra]] as a beacon to safely navigate the Warp, hence the title "Navigator".

==Ranks in the Navy==
While the Imperial Navy uses a lot of the ranks in similar fashion to modern militaries, they invariably hold to a more archaic form and are not equivalent to modern day ranking systems. Particularly since it's quite clear that commissions in 40k can often be purchased rather than earned, and that a "Warrant" would most likely hold to the original term and be an "officer by appointment" rather than an enlisted grade. Though considering the immense variety of units within the Imperium, this may not necessarily be the case galaxy-wide, so all options are equally valid. Also, the ship commander will generally be referred to as Captain internally for the sake of simplicity, except in Astartes fleets where they are called shipmasters to avoid confusion regarding the actual rank of Captain in the Astartes.

===Officer Ranks===
*'''Lord-High Admiral of the Imperial Navy''' - This guy is a [[High Lords of Terra|High Lord]] and is the single dude responsible for the '''ENTIRE''' Imperial Navy, though likely he doesn't do much other than delegate to his subordinates and attend tedious High Lord meetings.
*'''Lord-High Admiral''' - There are five of these guys, one for each Segmentum. While they're probably never anywhere near the front lines they probably have more to do, since its their job to oversee the deployment of fleets and materials from sector to sector.
*'''Lord Admiral''' - The guy in charge of a sector fleet who gets direct command of vessels and formations. You see these guys in the fluff quite regularly when "key" worlds ''(like Armageddon)'' need defended or attacked.
*'''Solar Admiral''' - Often a ''terminal'' rank... no really. Occasionally regular Admirals who do good jobs can put themselves forward for promotion to this position, which needs to be approved by the Lord-High Admiral of their Segmentum, then the officer needs to travel to Terra be reviewed by the Lord-High Admiral of the Imperial Navy. Obviously this can take a very, ''VERY'' long time to approve. So they might often be [[Grimdark|dead before the paperwork gets rubber-stamped]]. If they do get approved they are likely to get promoted straight up to sector commander (see Lord Admiral) as a position will probably have opened up while he was waiting. More rarely, Solar Admirals can get sent on "detached duties" which is basically a license to do as they please with their independent fleets.
*'''High Admiral''' - Commands several group of naval fleets (e.g. Battlegroups), often the most senior Navy officer in a Crusade but the things these fucks usually do is just having snacks with their Imperial Guard counterparts and leaving the combat duties to their subordinate Admirals
*'''Admiral''' - Gets put in charge of a fleet and told to oversee some subsectors. He's usually the highest of the "front line" ranks and much of his time will be on active duty patrolling his assigned region.
*'''Vice Admiral''' - Fleets traditionally get split into three parts, with the highest Admiral taking up the portion containing the larger ships, while the "Vice" Admiral takes the "Vanguard" portion of faster moving ships.
*'''Rear Admiral''' - the third portion of a fleet would be the "Rearguard" and usually gets assigned to the youngest/least experienced Admiral in the fleet. His job is usually the quietest one as he gets the mop-up and repair duties.
*'''Commodore''' - an experienced Captain in command of a squadron of capital ships. It's traditionally only a temporary rank, as capital ships don't always get assigned to each other the same way that escorts do. But the realities of war often mean that ships stay together for extended periods, often well beyond the lifespans of generations of captains.
*'''Lord Captain''' - not actually a rank, but an honourific applied to Captains of detached vessels operating independently. The '''"Lord-"''' part implies that they operate with the full authority of the the Imperial Navy when they act so they can deal with outside organisations (like planetary governors, Space Marines or Imperial Guard) on relatively even footing. Sometimes also known by the more archaic term of "Flag-Captain", since as the commander of a detached vessel they figuratively carry their own flag.
*'''Captain''' The commander of a single capital ship or the lead starship in an escort squadron.
*'''Commander''' - Usually the commander of an escort vessel. Is also the ranking officer on board orbital space stations. It also gets used as the terminal rank amongst Pilots, since small attack craft all fall under the remit of the Navy; so a '''Wing Commander''' would get command over all pilots based on a single carrier.
*'''Lord Lieutenant''' - The second-in-command to captains of capital ships, bizarrely Commanders don't hold that role and hold their own positions. Thankfully because a chain of command exists in any military, despite a Wing Commander holding higher "actual" rank over a Lieutenant on a carrier vessel he would not hold any higher authority on that ship than his duties allow for.
*'''Lieutenant''' - a "working" rank. Either holds command over small system vessels or acts as second in command to Commanders of escorts, or as department heads on Capital ships. They are also Squadron leaders amongst pilots.
*'''Sub-Lieutenant / Ensign''' - Team leaders or attack craft pilots
*'''Midshipman''' - Apprentice officers who haven't passed any exams or earned any responsibility, they would exist below the Warrant Officers in terms of authority, despite holding a commission. Midshipmen are commissioned from Imperial Nobility as part of the [[Administratum|Imperial Tithe]] ''(which can mean virtually anyone gets the job if they send their useless heirs just to keep the best ones at home)'' but they are also assigned from the [[Schola Progenium]]. In addition, Midshipmen also may be taken on as a personal favour from the Captain of a vessel if he knows the family. This echoes the ancient real-world practice of young noblemen showing up while the vessel was in dock with a letter from their family and being granted a commission on the Captain's say-so.

===NCO Ranks===
*'''Ship Master''' - the most senior Warrant officer on board a starship, also quite possibly the busiest man on the starship. It's his job to maintain the logs, update stellar navigation charts, oversee ships stores and order supplies, and command a hangar deck if there is one. Basically he's the guy who knows the ship better than anyone. In real-world historical usage, this guy would have an authority equivalent to a Lieutenant on board a starship, and would "mess" ''(ie: occupy the same space)'' as the other officers do.
*'''Bosun''' - ''(Shorthand for Boatswain)'' The NCO directly responsible for all of the common crew members, including [[Commissar|maintaining discipline]]. Despite his position, his actual rank may vary depending upon the size of vessel or operational requirements, in practice it never really matters since he's unlikely to ever meet another Boatswain. ''(real-world Boatswains are typically petty officers or warrant officers, but could be of any rank. They held responsibility over all areas of the ship other than Engineering, which was left to the Chief Engineer, as if the bosun disciplined/executed/imprisoned a skilled crewman from that department the ship could be crippled because of it)''.
**Note that most Capital Ships, but not all Escort ships, may have an actual Naval [[Commissar]] on board in this role, tasked with maintaining discipline up to and [[Blam|including]] the Officer compliment.
*'''Chief Warrant Officer''' - Also called "Chief Petty Officer" on some vessels. Will often be given command of important ship sections ''(like Chief Engineers, helmsmen, or auspex control, as these are are critical to ongoing operation of a starship)''
*'''Warrant Officer''' - You'll find lots of guys of equivalent rank on a ship, in command of various operational sections keeping the ship running at all times:
**Masters of Ordnance - make certain that Torpedoes and Attack craft (if any) are fueled and maintained.
**Master Gunner - have responsibility over all of the weapons batteries through the Gun Captains and make ensure they are loaded and fired when required.
**Master-at-Arms - responsible for all "small" arms on board a starship, overseeing all Sergeants-at-Arms, as well as maintaining order over any barracked Guard regiments currently in transit.
**Master of the Vox - making sense out of the bazillions of messages that run through the bridge at any given moment both internally and externally ''(crews can get pretty massive, and a lot of traffic can come through at once)''.
**Steward - the guy who keeps everyone else well fed.
*'''Gun Captain''' - Funnily enough, the man in charge of a single gun crew. Makes sure that the weapon is taken care of, is reloaded quickly enough, and is accurate when asked to fire. All of that comes back to this guy.
*'''Sergeant-at-Arms''' - Man in charge of the weapons lockers and leader of boarding parties, as well as maintaining ship-board security. Usually they are transferred from [[Imperial Guard]] regiments so that they don't have any prior association with the crew.
*'''Armsmen''' - Crewmen trusted to carry weapons more than a standard issue Lasgun/Laspistol. They are not true soldiers as offensive boarding actions tend to be rare. So these guys still have their own regular responsibilities on board ship. Since they are trusted more, they have slightly more freedom to move around the vessel as well, though most Imperial employees really don't want the job, since it means they get scrutinised more, or they could end up beating up their buddies.
*'''Voidsmen''' - the lowest rank of crewman on board a Naval Starship above the [[Servitor]]s unless the Captain is cool with slavery. If they have a skill or a trade they may be referred to as '''Able Voidsmen''' which is an official rank that might require examinations. Additionally, if they show leadership qualities they might be promoted to '''Leading Voidsman''' and put in charge of work gangs and be considered for promotion to Warrant Officer if a position opens up.

==Notable Problems==
These are problems some have with the Imperial Navy and their fluff....

===General Logistical Problems===
The big problem that the Imperial Navy has is that it's the only organised navy in the galaxy that's trying to defend its massive amounts of space. To do this takes vast numbers of ships but rather thinly spread out. Given the problems of warp travel it's also extremely hard to reinforce friendly fleets under attack. The foes of the navy come essentially in two flavours; raiders who might just manage to scrape together a few converted transports (building even escort-sized ships is a huge undertaking, akin to building damn near the entire American Navy combined from iron ore and making it fly) which take an escort squadron to murder, and huge organized invasion fleets that take a whole fleet to fight. These combine together to mean that outside of fleet bases and important strategic worlds there is nowhere in the Imperium that is actually well-defended. At best a fleet has to be formed and sent out and they could arrive months later. Travel takes a lot of time, and out in the void it can be extremely hard to know what you are actually fighting against, especially since the enemy tend to kill anyone who tries to look at them. So when there's a large enemy force that you absolutely must fight (not fighting is much preferable) you don't just band together whoever was within shouting distance of the flagship and go murdering, you pull together every single vessel in the sector and hope to the Emperor it's enough to do the job.

TL,DR: Acquiring a force sucks when command thinks paperwork and red tape are forms of worship and maintenance thinks the toilet needs a prayer before it is unclogged.

Warships genuinely are vast things and obscenely expensive and risking them at all in major actions is not something anyone does lightly. Each cruiser is larger and more complex than a fully-kitted titan legion. These things are MASSIVE. In the BFG book there's a fluff story of a cruiser being built at a shipyard that orbits a primitive world. The entire population of the planet were given over to mining the resources needed to build one single cruiser. It took them eleven years to mine the ore. Sure, that's a primitive world, but if you think about it that makes carving out the rocks for it the largest single project ever engaged upon without mechanization. If you add together all seven wonders of the world you aren't even close to the pile of rock we're talking about. So these things are a big fucking investment and the high lords really don't like risking them without a really good reason (<s>makes you questioning why they wouldn't build 20 smaller ships instead</s> ship sizes don’t work that way; 20 smaller ships against something capable of killing fifty ships that size is stupid so you build the one large ship so it lasts long enough to be a real threat).

So if you ever wondered why the Navy doesn't get more action, now you know. By the time the big, awesome ships get on the scene the invasion already probably finished and the bad guys moved on. Then you nuke the shit out of them from orbit or drop millions of poor bastards into the meat grinder. Far better idea all round. It's the reason that the enemy, even nutters like Chaos, don't fight in the void without reason. On the ground it's just a scrap, and maybe you win or maybe you don't. If you lose in the void then your campaign on the surface is dead. No reinforcements, no support and a massive constant orbital bombardment to kill everyone left (which sometimes doesn't happen, because, you know, plot armour). That tends to mean fleets hover around and not fighting, one ensuring the other can't directly interfere with the surface war. This is actually an excellent and realistic explanation for why there is significant ground warfare in 40k. Also, ground-based defenses, mobile theater-shields, etc. are common. So, attacking a planet worth anything is like attacking a planet-sized Death Star without the super-weapon. Your ground forces taking out shields and anti-space batteries is critical to achieving anything. But, by that point, most of the enemy is dead and the survivors have either moved to the next defended region or got so stuck-in with your dudes that you can't shoot without killing your own army. Unless you worship Khorne, in which case you really couldn't care less who you kill, even yourself.

So, the navies of the galaxy ultimately get pushed down into either raiders, escorts against raiders, raider-hunters, or babysitting and logistical duty for groundpounders. Which of course brings back the question of why the Navy has such a desire to get more interceptors and bombers for ship-to-ship combat when they rarely engage in combat in the first place and the attack craft are insufficient. Could be to weaken the enemy ships' ability to shoot at the surface, but by the point they would have a target it would have (as stated) gone to a new defended location or whatever else, defeating the point of sending attack craft to weaken the enemy ships' offensive power. They won't shoot at each other, and they can't shoot at the surface (or at least can't shoot anything worth shooting at). In exchange for packing in so many attack craft into hangars designed for countless atmospheric air support fighters and bombers, the Imperial Guard has to die in radically greater numbers than they have any need to since they have limited anti-air capabilities and all of their enemies have no problem sending massive swarms of fighters and bombers at them. That is without even getting to engage the enemy on the ground and not counting the countless soldiers killed as the transports are shot to pieces due to their escorts commonly ditching them to go after obvious bait tactics.

Thus the rumor that the Navy has no balls. But who needs balls when you have a nova cannon sized dick and eighteen dice worth of fire power.

===Ship Size===
No one is quite sure how big the ships really are. One story claims the Retribution-Class is a mere 3 kilometers long, while another says it is 9 kilometers and up to 20 kilometers.

Your best bet is Rogue Trader, although going by those figures, anything bigger than a cruiser has an average density around that of hydrogen... From a helpful poster on [http://www.heresy-online.net/forums/showthread.php?t=63267&page=2 Heresy-Online] we have this:

For the most accurate scale, look towards the Battlefleet Koronus Expansion, as it is more a stat/rule book than a story. That and previous consensi, as well as cross referencing with the Horus Heresy rulebooks by Forge World (which places Battleships at 8-12km) place Cruisers just above 5 kms, and Battleships in the mid 8s. Please note that most ships above the size of 8ish kilometers are either a unique modified/purpose built flagship or a ship of a small class that is not in widespread calculations. For a sense of scale the largest warship in the world is currently the US Navy's Ford Class Aircraft Carrier measuring in at 337 meters long or 0.337km making the USS Ford the size of a cannon. They have guns literally the length of an Aircraft carrier!

Ultimately, direct numbers are likely useless. The lance turrets have been described as the size of cities and given the size of an Imperial or even a modern city...also, there are about 75 ships in a Sector Fleet. A sector is one thousand cubic lightyears and there are about a thousand sectors in the Imperium. Which means logically those ships should be incredibly massive and easily ten or even a hundred times larger than the size numbers given in fluff given the size and industrial might and manpower of the Imperium.

*Transports and other Attack Craft, typically rated for atmospheric operation; also includes ships designed to be boarding torpedoes.
**<1 kilometer. That's the small ones, there are super transports in 40k as well. (A [[thunderhawk]] would go here).
*Escorts are "small" ships, like the Cobra, designed to flank foes and operate in squads.
**1-2 kilometers.
**Heavy Frigates
**Frigates
**Corvettes
**Destroyers
**Freighters
*Light Cruiser, a smaller Cruiser.
**3-5 kilometers.
*Cruiser, the standard fighting vessel; every Imperial fleet has them.
**5-6 Kilometers.
*Battle Cruiser, a beefed up Cruiser; generally more 'modern' than a Grand Cruiser.
**6-7 kilometers.
*Grand Cruiser; pocket-sized Battleship, very old.
**7-8 kilometers.
*Battleship; the biggest of the lot, simply put.
**8-12 kilometers.
**Battleships
**Fleet Carriers

The Horus Heresy novel "Know No Fear" had this to say about ship sizes, taken from [http://archive.foolz.us/tg/thread/22848349/ /tg/] who quoted it from the book and written here is just the lengths and names of the ships, for simplicity and space:

*Macragge’s Honour. Twenty-six kilometers - Flagship
*Spirit of Konor. Seventeen kilometers - Battleship
*Antrodamicus. Twelve kilometers - Grand Cruiser
*Antipathy. Nine kilometers - Cruiser (note that the book said it had "six thousand lives" on board, which would be an absurdly small crew for its size by 40k or even 21st century standards - Cruisers normally have 85-95 thousand crew in 40k, and that's for normal sized ones, not double length ones like this one. But this is a Horus Heresy ship, so perhaps it's automation was much better then a later 40k ship)
*Aegis of Occluda. Seven kilometers - Class unknown
*Gladius. Four kilometers - Escort
*Then there is the Abyss-class created by Lorgar that is said to match the Phalanx in size. He made three of them.

===Weapon Effects===
If the weapons can annihilate a continent, why can't it destroy a mere hive? Because different writers don't talk to each other that's why. Also shields maybe.

Alternate take: Sure these weapons can destroy continents, but generally speaking why would the Imperial Navy want to bombard a probably Imperial Hive? Another thing to consider is that while Imperial warships are capable of *BLAM*-ing a planet, it requires a lot of ships firing either specialized planet-killing ordnance or just bombarding round the clock. One virus bomb/Cyclonic torpedo/lance shot would do comparatively little damage. But it does make you think about how powerful those void shields must be.

Another take: Something to keep in mind is the different size of ships and thus cannon barrels. A Retribution-class battleship is a lot bigger than a Mars-class battlecruiser is a lot bigger than a Turbulent-class heavy frigate, just to name a few. Different ships have different weapons.

Another Alternate take : The heresy novels elaborate a little on little on the practicalities of Orbital bombardment as a battlefield weapon. Whilst it is occasionally used tactically and reserved as a strategic level weapon, it requires utterly pinpoint accuracy (targeting being off by a millimetre in orbit could result in a shot being kilometres off on the ground) which is only possible when orbit is completely uncontested. It's use during land battles is the VERY definition of Danger Close and often a dead giveaway to the enemy, as allied forces have to withdraw kilometres away before ordering a bombardment, letting an enemy force bunker down or get out the way. Ships are also very easy targets for anti-orbital weapons during bombardment and the effect of a starship hulk hitting a planet you're fighting for is not something to be risked.

Alternate alternate take of an alternate take take: Hives are designed to withstand bombardment from orbit while firing back with enough power to make enemy ships stay away. This is the main reason why massive ground engagements happen (and there are theater shields available, too). For example, the Rock of the Dark Angels survive Caliban being essentially turned into its component atoms via mass bombardment. Also, the previuos "Another Alternate take" directly above this one is right. Now combine that take with this one and really the only way to take an enemy position is to get off your ass and do it yourself the manly way.

Alternated take because alternate takes on alternate takes don't take what it takes: most weapons are jackshit useless against a planet with atmosphere and magnetosphere. Nova cannon shots, plasma bursts and lance batteries are distorted by magnetic fields, macrobattery shots burn up in dense atmosphere, just like torpedoes and most void-faring attack craft.
To fire effectively the ships either have to come CLOSER into low orbit (being exposed to oversized cannons and missile launchers that can be seen around every major spaceport and hive city) and risk being burst open like a pinata, or are forced to just shit bombs from high orbit, being absolutely horrible at aiming.

===Lack of Balls===
It is well-known that most Imperial Navy Officers don't have em.

An Imperial Navy fleet is most effective when Inquisitors take it over. [[Exterminatus|See Here]].

===Carrier Hate===

Back in M36, the Imperial Navy fought a lowkey civil war over fleet doctrine in Segmentum Tempestus known as the Gareox Incident. A cabal of chaos worshipers worked their way high enough in the navy to start designing ships that were ready-built to turn traitor, most of which were carriers. The battlefleet eventually figured out something was off and the result was a giant carriers vs battleships fight that went down the way the Battle off Samar would have if the Japs hadn't been scared shitless by three destroyers. The surviving carriers went openly traitor and since then building new carriers has been borderline heresy so far as the navy is concerned. They don’t hate carriers, but many Imperial ships are basically battlestars, making carriers a pointless waste of resources. Attack craft are mostly used to weaken enemy firepower, shoot down torpedoes and enemy fighters and bombers and boarders, and finish off crippled enemy ships. On their own, they’re largely useless for actually defeating enemy ships. The main reason aircraft are so effective against navies in WW2 and modern navies is that they can use momentum for bombs and missiles to strike hard from above in order to penetrate decks. Space has no such option and every attack from any angle is similar to a torpedo plane attack run from the Second World War. Which is why Starhawk Bombers are basically just torpedoes. However, carriers are useful and accepted, just not useful enough to bother building from scratch and so carriers are almost always either repurposed wrecks of other ships or mothballed carriers being deployed where more attack craft are needed. This almost pointlessness also means carriers are looked down on as barely worth calling support ships.

==Music of the Imperial Navy==
Not to be outdone by the Imperial Guard (as well as to compensate for their aforementioned lack of balls), the Imperial Navy has begun collecting music to either be blared on loudspeakers when not in active use, or in the case of battleship command decks, played live by orchestra. the first four are taken from [[Battlefleet Gothic Armada|Battlefleet Gothic Armada.]]
