The largest Dominion warship of the Dominion War, more than twice the length of a Galaxy-class starship.
The Jem'Hadar battleship was the largest Dominion warship seen during the Dominion War, more than twice the length of a Galaxy-class starship and bristling with weapons.
In Valiant, the cadet crew of the USS Valiant, led by Cadet Captain Tim Watters with Nog and Jake Sisko aboard, attacked a battleship that was still undergoing trials. The attack failed and the Valiant was destroyed, with only a few survivors. Fully operational battleships later took part in the climactic fighting of What You Leave Behind.
