IKS Roc’Tar
From Star Trek: Theurgy Wiki
The IKS Roc’Tar was a Klingon starship in service to the Klingon Defense Force in the 24th century. It was a Bird of Prey.
The IKS Roc’Tar was one of the many Klingon ships destroyed in the Dominion War. Before the Roc’Tar exploded a Gorn servitor mechanic named Sithick managed to get to an escape pod and was rescued by the Federation ship USS El Dorado.
(The class of the IKS Roc’Tar has not been revealed but it was either a B'rel-class scout or a K'vort-class cruiser.)
