===Klingon Empire===
{{topquote|Klingons hardly ever update their fleet designs. They always want their ships to look like big stupid birds.|Dr. T'ana, The Lower Decks}}
Klingon ships are about aggression. They're not as technologically advanced as their Feddie counterparts nor do they carry their multi-role capacities, but they have a lot of forward weapons and are made to get into the fight and overwhelm their foes with a lot of firepower.

*'''D7 class''': The original Klingon Battle Cruisers used during the Federation-Klingon Cold War. These were deployed in response to the Constitution Class ships and later on the USS Excelsior at least once. A variant or refit, the K't'inga class was used during their misguided campaign against the Cardassian empire and the battles of the Dominion War. Where they were more or less equivalent to Starfleet's refitted ships of the same era, The Miranda & Excelsior classes.

*'''B'rel class''': a.k.a. Klingon Bird of Prey. First seen in Star Trek III and used as a whale transport in Star Trek IV it became the main Klingon ship through TNG and into DS9. [[Scale Inconsistency|It's generally listed as being 157.76 meters...but the model has been used for both tiny fighters and 600 meter long ships that could tango with a Galaxy-class ship]]. Lower Decks addressed this by making a class of larger ships similar to the B'rel in shape but keeping the bird shape due to an apparent culture obsession. 
*'''K'Vort class''': The Bird of Prey, but the size of a light cruiser. Starting from The Next Generation. It was used as the main ship of the Klingon Empire until the Vor'Cha was introduced. Also nearly as wide as the Feddie's Galaxy class despite its smaller size. While the IRL reason is that VisionArt Design & Animation didn't create a CGI model for it. In universe the K'Vort's crusier role was supplanted by the K't'ingas and Vor'chas. So one can easily guess that most them were either lost during the Klingon Civil Wars(with the House of Duras getting help from the Romulans before being exposed by Starfleet), The Klingon-Cardassian War, some possibly lost to Federation vessels after withdrawing from the Khitomer Accords or Jem'Hadar warships. As the Jem'Hadar had them limping back to Fed boarders after the Cardassians joined the Dominion. Those  three conflicts only happened because the Dominion's Founders took advantage of Chancellor Gownron's arrogance and left the Khitomer Accord, to their advantage. As no K'Vort Bird of Prey's were seen on screen after the empire rejoined the treaty nor during the battles of the Dominion War.
*'''Vor'cha class''': Introduced during TNG Season 4 as the new Klingon warship of that era. The Vor-Cha is the first new ship since the introduction of Bird of Prey. As K'Vort was mainly the original model with the wings turned upwards. Armament wise its somewhere between the Galaxy and Nebula classes(+combat pod) with a standard array of Disruptors and Photon torpedo launchers. They can also achieve a Warp factor of over 9.5. Most Vor'cha class ships seem to be attached to the Klingon Defense Force (the empire's formal military), with older designs still being used by the various great houses that form the High Council. One served as the flagship of the Klingon Chancellor until the Negh-Var class made its debut. Though the Vor'cha appears more often as the Klingon's Empire primary capital ship.  Many of them fought in conflicts the empire got themselves pulled into. 
*'''Negh'Var class''': The Klingon's answer to the Galaxy Class and presumably the first(and maybe only) vessel is their Flagship in the latter half of the 24th century. Presumably a descendent of the Vor-Cha. She only appears in two or three episodes. Despite her impressive looks and size, the Negh'Var is known for getting its ass kicked more than a few times. Once from the crew operating Deep Space Nine after being conned by the Dominion's Changeling Founders. Than expelled from Cardassian Empire' space with her fleet after they joined the Dominion. The Negh'Var's model was originally used as the alternate future Klingon Attack Cruiser in TNG's series finale two parter. With one being destroyed by a supped up version of the Enterprise-D. Its most prominent appearance was its used as the Regent's Flagship in the post alternate Terran universe. That ship got a beatdown from an alternate copy of the Defiant and a Terran Raider(the Terran Resistance's version of the Federation Attack Fighter). Nor did it have a cloaking device like its counterparts from the main universe. As Rom, one of DS9's best civilian engineers from the primary reality. This happened because the Regent and his Alliance subordinates are morons, allowed Rom to rig a cloaking device they stole (from a B'rel class) to disable her. This let the Terrans Rebels arrest its crew so they could be rescued allowing Quark and Rom to be returned to their home universe.
