The Qang-class (translated from tlhIngan Hol as Chancellor-class) was a type of Klingon heavy cruiser starship in Imperial Defense Force service beginning in the late 24th century. Twelve ships were commissioned by early 2376, and were named for the twelve then-most recent Chancellors of the Klingon High Council. Outwardly, the Chancellor vessels resembled Vor'cha-class attack cruisers, with different upper hull constructions.
