The I.K.S. T'Ong is a Klingon K't'inga-class battle-cruiser that was sent by the Klingon High Command on a long-range mission in the year 2290. Returning from the mission, Captain K'Temoc and the crew of the T'Ong woke from a cryogenic stasis 75 years in the future. They encountered the U.S.S. Enterprise-D and learned that the Federation-Klingon War had ended.
