Romulan Warbird (22nd century)

From Memory Alpha, the free Star Trek reference

The Romulan Warbird was one of the starships the Romulan Empire used in the 22nd century.

It was possible to use a tachyon pulse to weaken the shields of such a vessel. Two of these ships were modified to become Romulan drone-ships by installing a remote control. This allowed the ships to be controlled from Romulus. (ENT: "Babel One", "United", "The Aenar")
