The Klingon Bird-of-Prey was a type of warship utilized by the Klingon Empire serving the Axis of Empires from the start to the end of the First Multiverse War. It is used by the Horde also, mainly the Rebels led by Duras, son of Ja'rod. This type of craft, initially descended from its counterpart from a century earlier, was one of the most versatile warships employed by the Empire, serving a variety of mission roles, including that of a scout, raider, patrol ship, and cruiser. The Klingons applied several class designations to the different types of their Bird-of-Prey design, including the K'vort-class, B'rel-class and D-12-class.
Comparable in design to its 1650 N.E century predecessor, the exterior design of the Bird-of-Prey utilized the same basic avian design, including vaguely feather-like hull plating on its wings.
The bulk of the ship's overall mass was incorporated in the aft section of the ship. The bridge module was located on a bulbous forward section, which was separated from the aft section by a relatively thin connective section that attached to and flared into the aft portion, which swept from the main body, forming wings. The wing-design was characterized by its multi-positioning for various flight modes. Located on the caudal section of the ship were the ship's cargo bay, impulse engine, and warp nacelle. The nacelle was positioned diagonally along the aft section of the ship, above the cargo bay, and perpendicular to the impulse engine.
