List of unnamed Jem'Hadar battleships.
The Valiant's target
This battleship was introduced in 2373. Captain Ramirez was given orders by Starfleet to use the USS Valiant to collect technical data on it.
After Ramirez and the senior officers of the Valiant were killed, Tim Watters decided to complete the mission. Several months later, the Red Squad cadets later detected the battleship and shadowed it for several hours.
The cadets later discovered what they thought was a design flaw and mounted an attack. The mission did not go according to plan and the battleship was not seriously damaged. The ship returned fire and eventually destroyed the Valiant. (DS9: "Valiant")
Cardassian base attacker
This battleship attacked and destroyed a base of the Cardassian Rebellion in late 2375. It was later featured on a Dominion propaganda message recorded by Weyoun. (DS9: "The Dogs of War")
Orbiting Cardassia
These battleships formed part of a Dominion defense perimeter around Cardassia Prime after the Dominion retreat from the Battle of Cardassia with the Federation Alliance. (DS9: "What You Leave Behind")
