The Romulan Warbird is one of the largest ships the Federation has encountered. Its width is comparable to three Galaxy class ships, length is two Galaxy class ships, and is slightly shorter in height than a Galaxy. This ship also has a strange power core that the Federation still does not understand fully. It uses an artificial quantum singularity as its warp core, very powerful, very strange. The Romulan Warbird also fashions the ominous cloaking device. This ship is huge and is almost as huge with its weapons capabilities. This ship is a threat to any ship in the fleet except for the Galaxy class which is a match-for one Warbird.
