The Tro'Qa class was a type of destroyer fielded by the Klingon Empire during the 24th century. (Ship Recognition Manual, Volume 3: Ships of the Klingon Empire) The Tro'Qa's design was heavily based on the B'rel-class. The major difference was that the Tro'Qa had four warp nacelles, two were on the tips of the wing pylons with the others mounted dorsally a third of the way down the pylon from the hull.
