USS Gloucester (NCC-65617)

The USS Gloucester (NCC-65617) was a frigate in service to Starfleet in the 24th century. 

In 2362, Admiral Henrietta Newton dispatched the Gloucester to the Doran system to search for the missing USS, which had disappeared while performing trials on a new black hole propulsion drive. An extensive search of the system and surrounding sectors failed to locate the Cotterill. (: "To Hell and Back")

The Gloucester was later destroyed in unspecified circumstances.
