The Negh'Var was designed mainly by Kurak, daughter of Haleka, and commissioned in 2372. (TNG novel: Diplomatic Implausibility) It was made the flagship of the Klingon fleet, serving as the command vessel for Chancellors Gowron and Martok during the Dominion War, and the conflict with the Federation that preceded it. One of the Negh'Var's first actions was the attack on Deep Space 9 in the year it was commissioned.
