Romulans have used a dazzling dizzying variety of ships in their time. First the Raygun Gothic "winged pancake" Romulan Bird-of-Prey. Lots of fan variants of the pancake and a 22nd Century D'deridex hybridized version of it on ENT. (Interestingly, here's a "Heavy Bird-of-Prey" from one of the comics, trying to get the original closer to its 24th Century successors.) We also saw the Romulans in "The Enterprise Incident" using Klingon D-7's. (Here's another era-in-betweener from the comics playing with Klingon tech, called the Moonhawk.) We never saw a Romulan ship between TOS and TNG on screen, and I talk/link to possibilities in my thread on the subject here. Infamously, the Klingon Bird-of-Prey was originally going to be a Romulan ship, but I don't know when in the design process the switch was made. Is the model entirely Romulan with a different name? It's pretty different from the K't'inga we saw in TMP... (I think I argued against.) Also in the comics for this time we saw FASA's Nova Class Battleship, again vastly different from both the TOS BoP and TNG Warbird shapes. Then the Romulan Warbird. (...whose designer nearly made a vertical warbird and later created an even more massive vertical ship for the Ships of the Line Calendar.) The Earth-Romulus War Era Early Romulan Ship was created by show modeler Greg Jein and featured in multiple official reference books, this time showing an old-fashioned sci-fi "Ming the Merciless's flagship"-like configuration. Also vastly different is the [hopefully forgettable] Romulan Drone used on ENT, which was a reuse of a CG from VOY, I think. Then came the Tim Burton Octopus Decepticon Narada used in Trek '09. Finally, I'd like to include the again-differently-shaped Kestrel Class from the upcoming fan film Pacific 201. ...I'm usually unimpressed by the countless "wicked green bird" designs fans and PTB alike come up with for the Romulans (even if some are a little different), and often sigh at the not-very-alien-ness of them. Maybe because I love the supercilious baddies so. (And man is that organic tri-hulled warbird inspired!) Thinking about the variety of designs they've employed over the years, I found myself realizing that they really are among the most diverse shipwrights we've ever seen. I Romulan salute the Star Empire!
