The Jem'Hadar Battleship was a large battleship used by the Dominion for fleet engagements during the 2370s.

A group of these warships formed part of the first wave of Dominion ships to pass through the Bajoran wormhole, following their annexation of the Cardassian Union in 2373.

Its first notable appearance in battle against the Federation was at the outbreak of the Dominion War in late 2373, where it served as a capital ship of the combined Dominion and Cardassian fleet.

The Jem'Hadar Battleship was equipped with both directed energy weapons and torpedos in its arsenal. The forward torpedo launcher was the primary utilized in a majority of engagements with the Federation during the Dominion War.

This torpedo launcher was capable of firing multiple bursts in a single volley. They were also equipped with a forward beam emitter. During the initial invasion of the Alpha Quadrant, these vessels were individually supported by a cluster of Jem'Hadar fighters.

A single vessel of this class was perceived by the crew of Deep Space 9 as a potential threat after targeting the station in mid-2373.
