The first of the Klingon fighters, this craft was designed to support the fleet by picking off isolated enemy ships or mopping up cripples. It is tediously slow and barely maneuverable, but makes up for this with a large anti-ship gun. Designed in tandem with the Z-2 (though entering active deployment several weeks before it, grasping the title of first fighter on active service), this fighter remained in service until the Bird of Prey project led to fighter production being seriously curtailed.
