Vas Hatham class

The Romulan Bird-of-Prey was a Romulan starship class in the 23rd century.

History
The Bird-of-Prey was brought into service in the 2260s as the Romulan Star Empire began it's plans to re-establish it's self as a major power after a century hiding behind it's boarders. After the first tests of two of the ships were successful a single Bird-of-Prey was sent over the Neutral Zone to test the Federation's strengths. (ST reference: Ships of the Line)

The lone Bird-of-Prey successfully struck a number of Federation outposts before it was pursued by the USS Enterprise, and eventually destroyed. (TOS episode: Balance of Terror)

The Bird-of Prey served throughout the rest of the 23rd century and final ships of the class were finally removed from service in the early 24th century. (ST reference: Starship Spotter)

Features
The Bird-of-Prey is warp capable and fitted with two innovative systems; a plasma torpedo weapon capable of massive destruction, and a revolutionary new cloaking device. However the power demands of all these systems are limiting factors on the ships abilities as the ships power core and only produce enough power to use one of the three at a time.
