USS Prometheus (NX-74913)

The USS Prometheus is the prototype for Prometheus-class Federation starships. Romulan spies managed to hijack the ship and attempted to return to Romulan space with it, but they were thwarted by the combined efforts of the ship's Emergency Medical Hologram and the EMH from the USS Voyager, who had transmitted himself to the Prometheus in an effort to contact the Federation from the Delta Quadrant.
