- See also IKS K'tanco.
In the mirror universe, the IKS K'tanco was a D7-class, specifically of the K't'inga-class, Klingon battle cruiser starship in Klingon Alliance service in the 23rd century, operational in the early 2290s.
In 2293, K'tanco, along with the IKS Klothos's mirror duplicate, escorted the ISS Excelsior out of Klingon space, when the group was set upon by enemy fighters. (TOS video game: Shattered Universe)
- The regular universe K'tanco was mentioned as Kang's command in a cut line from the DS9 episode: "The Sword of Kahless", leading us to believe that the mirror Kang might've been commanding the counterpart vessel.
