One of the smaller warships employed by the Klingon Empire, the B'rel Bird of Prey is also one of the most common. The B'rel was the first Klingon ship to mount cloaking technology after its procurement from the Romulan Star Empire in the 23rd Century. Small, nimble, and stealthy, the B'rel has served as an excellent light combat craft for the Klingons into modern times. Requiring little more than a dozen crew members, B'rel Birds of Prey have been built in great numbers. Enough have been built over the years that some have even fallen into the hands of raiders, pirates, and foreign navies.

Individually, each B'rel is unable to take on enemy cruisers head to head, but in groups they are a force to be feared by even the most potent enemy battleship. A pack of B'rel Birds of Prey on the hunt are a deadly force to be reckoned with.
