IKS Toh'Kaht
The IKS Toh'Kaht was a Klingon  attack cruiser that was in service with the Klingon Defense Force in the mid-24th century. 

In 2369, the Toh'Kaht traveled to the Gamma Quadrant under the command of Captain Tel-Peh, first officer Hon-Tihl and medical officer Kee-Bhor. The vessel was on a two month bio-survey mission with intentions of finding a suitable planet for the first Klingon colony on the other side of the Bajoran wormhole. The covert secondary mission of the Toh'Kaht was to discover alien weapons technology, and return it to the Empire. 

Approximately three weeks after departure from Deep Space 9, the Toh'Kaht returned through the wormhole a month ahead of schedule. Immediately after clearing the mouth of the wormhole, the vessel exploded. Further investigations found that the ship had been sabotaged and was destroyed from the detonation of a thalmerite device on a beam near the ship's reactor core. Hon'Tihl was the only survivor of the explosion, but died shortly after beaming to the station. 

It was later discovered that the Toh'Kaht crew had fallen under the influence of an energy matrix from the Saltah'na energy spheres. During an exploration of , these spheres were discovered by the crew who had the spheres brought aboard the ship. After opening the spheres, the matrix caused paranoia and factionism amongst its crew, a re-enactment of the events that led to the destruction of the Saltah'na species. ()
