Editing Imperial Navy (section)

=== 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 (makes you question why they wouldn't build 20 smaller ships instead).

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.

Besides that, there are strategic locations to take in order to take or destroy the anti-orbit defenses. Those locations have strategic locations and so on and before you know it, you’re invading the whole damn planet.

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. Oh, and sending reinforcements from other worlds, let alone the loss of expensive and valuable drop ships and interstellar transport vessels, is far more expensive than just using damn atmo-fighters and bombers for the Guard. Heck, an escort ship variant was created specifically to resolve this problem as even the High Lords got pissed about it. A ship designed as an escort vessel specializing in carrying atmospheric fighters, bombers, etc. just to provide support for the Imperial Guard. The Navy promptly took the ships built, removed the atmospheric craft, and replaced them with Furies and Starhawks. They already have a light cruiser escort carrier and the number of attack craft they crammed in was abysmal.

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.
