IKSV Staav'eMara

The USS Morgan City (NCC-2704) was a Loknar-class (mark I subclass) Federation frigate starship in the 23rd century, entering Starfleet service on reference stardate 1/9107. The Morgan City was capured by Klingon Admiral Kamatao during the Four Years War and renamed as a Klingon "slave" vessel, the IKSV Staav'eMara ("slave of justice"). The vessel was active in the Klingon fleet for decades after the capture. (RPG reference book: Federation Ship Recognition Manual)
