2.39 Romulan Ships
Describes Romulan starships and their advanced cloaking devices, the Neutral Zone, the D'Deridex class warbird, and the Romulan scout ship.
In TNG, the Romulans only recently emerged from an extended period of isolationism, and thus very little was known about their technology. We do know that they have developed some formidable new ships in the interim, and that they are equipped with more sophisticated cloaking devices which render their ships nearly invisible to even our most advanced sensors. Because of the tremendous power drain involved, weapons systems cannot be used while the cloaking device is engaged. Romulan ships-of-the-line are generically called Warbirds.
A Neutral Zone still separates the Romulan Star Empire from the United Federation of Planets. This zone, about one light-year wide in most places, takes several hours to cross at Warp 8.
Romulan D’Deridex class Warbird: This is a huge vessel, which is probably more than a match for Voyager in terms of firepower. Maximum sustainable warp speed is about 9.1, slightly slower than that of Voyager. Power source is believed to be a system which harnesses the x-ray emissions from a captive quantum singularity. Armed with disruptor banks and torpedoes.
Romulan Scout Ship: Seen in “The Defector”. A small, minimally armed, warp capable vehicle. Substantially slower than the Warbird.
