The 4th Division Battleship is among the largest of the Jem’Hadar warships. They are significantly larger than a Galaxy-class ship and much more powerful. The Federation’s first contact with these ships occurred when they sent the U.S.S. Valiant on a mission to retrieve technical data on the Jem’Hadar Battleship and report back. Using the data they found on their sensor probes, the Valiant, under the command of Captain Watters, attempted to exploit a weakness in the Battleship. The Battleship swiftly dispatched them, which proved the firepower of this vessel.
