The Felg'ra-class was a Klingon warship that saw service during the 24th century. The class was first commissioned in 2346. (Ship Recognition Manual, Volume 3: Ships of the Klingon Empire) The Felg'ra consisted of two forward spars, which end with structures that appear like command hulls but in fact only contain weapons. The main hull connects the aft two-thirds of the spars and on top of that sits a broad wedge-shaped structure that contained the bridge. Two slightly downward curving wing nacelle pylons are connected to the dorsal side of the main hull. At the end of these wings were the ship's nacelles. At the aft of the main hull was a large impulse engine, with two smaller ones wedged between the wing pylons and the main hull.
