From ImperialWikiWarbird is the workhorse of the space navy of the Romulan Star Empire from the 2360s through the Dominion War.
- At over a kilometer in length, D'deridex-class ships are exceptionally large for starships of the Alpha Quadrant.
- Unlike Federation starships that use matter/anti-matter reactors for main power, Romulan Warbirds like the D'deridex-class derive their power from an artificial quantum singularity.
- Like most Romulan warships, the D'deridex-class is equipped with a cloaking device.
- The armament of D'deridex-class warbirds includes disruptors and photon torpedoes.
- The top speed of this class isn't known, but it is less than that of a Galaxy-class starship.
