The Taj class was a bird of prey design used by the Klingon Empire of the Mirror Universe.

These fighters were similar in shape to the larger Klingon birds of prey but were the size of Terran Empire fighter craft. They were equipped with a guided Photon torpedo as its primary weapon whilst Disruptor Bolts and a Plasma cannon were its secondary armaments.

In 2293 after saving the Klingon homeworld from the Doomsday machine, the Klingons gave Hikaru Sulu of the ISS Excelsior access to Taj class fighters for their use. (TOS video game: Shattered Universe)
