The IKS Kartadza was a K't'inga-class starship under Klingon Defense Force service in the early 25th century.
While ferrying prisoners from Ter'jas Mor to a Klingon maximum-security prison, she was captured by the Enterprise. In the reaping that ensued, Brianna Reiss took Alaa, a Klingon professor imprisoned for libel. Later, when the Lyran Star Empire reached a peace accord with the Klingon Empire, the ship, alongside the IKS Jon'ka and the IKS Pterodactyl-of-Prey, was returned to the Klingon Empire.
