IKS Pragh
From Star Trek: Theurgy Wiki
The IKS Pragh was a Klingon starship in service to the Klingon Defense Force in the 24th century.
In 2375, during the final weeks of the Dominion War, the Pragh was partnered with the USS Black Hawk on a few missions behind enemy lines prior to the Battle of Cardassia.
(The class of the IKS Pragh has not been revealed but it is likely a B'rel class.)
