IKS Ki'tang

The IKS Ki'tang was a Klingon Bird-of-Prey in service to the Klingon Defense Force in the 24th century.

During the Dominion War, the Ki'tang was part of Federation Alliance fleet gathered to defend the Chin'toka system during the Breen counterattack in 2375. It was the only ship out of the 312 strong fleet to survive due to its invulnerability to the Breen energy dissipator thanks to a last minute adjustment to the ship's tritium intermix before the battle. The Ki'tang's survival allowed for the Klingon fleet to be quickly made immune to the Breen weapon. 

Ki'tang rescued Joseph Tyler during the battle. (: War Stories: "Lambs to the Slaughter")
