The Jem'Hadar battleship was a type of warship employed by the Dominion during the Dominion War. (DS9 episodes: "Valiant", "What You Leave Behind")

In the 25th century this class was referred to as a Jem'Hadar dreadnought. (STO episode: "The 2800")

In late 2374, the Federation Starfleet starship USS Valiant conducted a mission to gather technical data on the new Jem'Hadar battleship that was reported to be operating in their sector. After learning that the battleship could cause massive destruction to Federation outposts, the team of Red Squad cadets in charge of the Valiant decided to attempt to destroy it. Despite the belief that they had identified a weakness in the ship's design, the Valiant was destroyed with relative ease. (DS9 episode: "Valiant")

Several battleships were later involved in the climatic Battle of Cardassia against Federation Alliance forces in late 2375. They later formed part of the Dominion defense perimeter in orbit of Cardassia Prime. (DS9 episode: "What You Leave Behind")

The Jem'Hadar battleship was still in service in the 25th century. (ST video games: Conquest, Star Trek Online)

Technical data

The class was said to be roughly twice the size of a Starfleet Galaxy-class starship, although some variants, such as those orbiting Cardassia Prime during the final battle of the Dominion War, were closer to three times as long. The vessel was armed with directed energy weapons and torpedoes. (DS9 episode: "Valiant", DS9 episode: "What You Leave Behind")

The class also had a rarer variant called a Jem'Hadar dreadnought carrier. (ST video game: Star Trek Online)
