Large Dominion warship that served as a command vessel for Jem'Hadar fleets throughout the Dominion War.
The Jem'Hadar battle cruiser was a large Dominion capital ship, roughly as long as a Galaxy-class starship, that carried heavy weapons and served as a command vessel for Jem'Hadar fleets alongside the smaller attack ships.
Battle cruisers appeared from In Purgatory's Shadow and By Inferno's Light onward, as the Dominion fleet came through the wormhole and Cardassia joined the Dominion. They went on to fight in nearly every major engagement of the Dominion War, from the struggle for Deep Space Nine to the final battle over Cardassia.
