USS Valkyrie
From Star Trek : Freedom's Wiki
The USS Valkyrie is an Intrepid Class starship, a retired training ship. On Stardate 2414.09.16, the USS Mithrandir encountered the ship and her injured crew as part of a Starfleet Training Excerise to prepare ship and crew for duty. Captain Kevin Jordan believed that the crew needed a shake down but it was more to the truth to say, that he needed time to reacquaint himself with Command Duties.
The USS Valkyrie was first seen in the USS Mithrandir Mission In Honor of Pyong Ko
