The USS Gemini was a Federation Soyuz-class starship in service to Starfleet in the 23rd century. It was seen fighting against the Klingons during the Federation-Klingon War. It was severely damaged during the Romulan Neutral Zone incursion, when it was docked at Outpost 6, which was attacked by a Romulan Bird-of-Prey. It was later repaired sometime before 2285, when it was one of the ships disabled by the powerful communication of the Whale Probe. It was commanded by Captain Samuel Harriman.
