Klingon cruiser

A Klingon cruiser was a type of cruiser utilized by the Klingon Empire during the 2360s and 2370s.

In 2364, the Klingon cruiser was sent to sent to apprehend the Klingon criminals Korris, Konmel, and Kunivas, who had commandeered the Talarian freighter Batris. The T'Acog attempted to disable the Talarian ship with phasers and photon torpedoes. The Batris was however able to destroy the T'Acog in the battle. The debris of the ship was discovered by the USS Enterprise (NCC-1701-D), though it couldn't be determined at first from the debris if the cruiser had been a Klingon or a Romulan vessel. 

The following year, another Klingon cruiser passing near the Theta 116 solar system reported discovering pieces of a strange vessel in the upper atmosphere of the planet Theta VIII. In response, the USS Enterprise (NCC-1701-D) diverted from its course to investigate. 

In mid-2374 three Klingon cruisers, under the command of General Martok were sent to bolster up the defense of the Dorala system during the Dominion War.
