Mentions the bird-of-prey depiction on ancient Romulan ships, which fits the The Star Trek Encyclopedia IIĪbandons the reference to the Romulan-War era ships, for they were never on screen and are A conjectural ship of the latter era is depicted in the book, along with aĬaption that it has impulse drive only. This is obviously the reason why the Star Trek ChronologyĪs well as nearly the whole fandom for some time took it for granted that thisĭrive, and that the same should apply to the Romulan ships around 2160 - considering that older ships are not "Impulse drive" in Star Trek is much like a synonym for Kirk: "Well, gentlemen, the question still remains: Can we engage them with a reasonable possibility of victory?" The only canon reference on propulsion ofĢ3rd century Romulan ships is Scotty's line about theĪttacking Romulan Bird-of-Prey in TOS: "Balance of Terror", where heĪscertains that the ship runs on "simple impulse". Nevertheless, some arguments may be still worth being taken into consideration. Only in more recent years there is definite evidence of Romulan ships with warp drive as early as in the 22nd century, namely the Bird-of-Prey predecessor in ENT: "Minefield" and ultimately the drone in "Babel One".

This problem has been debated by the fans for decades, and for some time it looked like the idea that they had no warp drive in the 23rd century prevailed. The technological question may appear subordinate at the first glance, but it will turn out essential for our interpretation of Earth-Romulan and But did the Romulans have warp propulsion back in 2266 in TOS: "Balance of Terror" (where they were said to have a ship with "impulse power only") or already during the Earth-Romulan War around 2160? Maybe warp drive was even known as soon as the schism between Vulcans and Romulans occurred 2000 yearsĪgo. Since when do the Romulans have warp drive? They must have acquired it at latest during their presumed brief alliance with the Klingons in 2267 when they were using Klingon ship designs, evidently with warp engines, as seen in TOS: "The Enterprise Incident".
