Negh'Var class

The Negh'Var-class was a type of warship fielded by the Klingon Empire in the latter half of the 24th century.

When it came into service it was one of the largest ships fielded by the Alpha Quadrant powers. The ship most notable features are two large weapon pods that are slung under the wings of the vessel. These pods contain two heavy disruptor cannons that are among the most powerful conventional weapons equipped on Klingon warships at the time.

The Negh'Var-class first saw service as the flagship of the Klingon Defense Force in 2372 where it led the invasion of Cardassia. The ship would also be involved in the following First Battle of Deep Space 9 where its heavy firepower, in particular its dual heavy disruptors, managed to bring down Deep Space 9's shields. 

When the Dominion War began in 2373 Negh'Var-class warships were rarely seen on the frontlines during the first three months. Starfleet officers believed that Chancellor Gowron was purposely holding these large warships back in Klingon territory to protect Klingon interests. (: "Regression")

The Klingon Ninth Battlegroup's flagship was a Negh'Var-class vessel under the command of General Gar. The ship led the allied forces during the Raid on Sector 432. (: "Pressure Points")
