The IKS K'tanco was a D7-class, specifically of the K't'inga-class, Klingon battle cruiser starship in Imperial Klingon Defense Force service in the 23rd century, operational in the early 2290s, commanded by Captain Kang, with his wife Mara serving as first officer.
In 2291, the K'tanco saved a Klingon base from an attack by two Romulan warbirds. Shortly thereafter, the K'tanco responded to a distress signal from Klaa's ship, which had been disabled by the Torye's subspace-disruption weapon. Upon arriving, the K'tanco encountered General Navok's ship, and inadvertantly discovered two Federation representatives, Spock and Harry Morrow, aboard. Upon learning the Torye's plan to capture a prototype Klingon mobile battle base, the K'tanco set off in pursuit, along with the Federation starship USS Enterprise-A, which had been pursuing the Torye. Together, both ships stopped the Torye and destroyed the base. (TOS eBook: Mere Anarchy: The Blood-Dimmed Tide)
- The K'tanco was mentioned as Kang's command in a cut line from the DS9 episode "The Sword of Kahless". In this cut or unfilmed scene, Kor dreamt the K'tanco appeared in the skies above Qo'noS after he brought the Sword of Kahless home and took him to join Kang and Koloth in Sto-Vo-Kor. The K'tanco itself was never mentioned to be a D7 but its mirror universe duplicate was, leading us to believe the two vessels were identical.
