The HMS Prometheus was a Prometheus-class starship under the service of the Hydran Royal Navy. She boasted a multi-assault vector mode which allowed the ship to separate into three vessels, each with weapons platforms and capable of warp travel as well as atmospheric flight. However, contrary to its Federation counterpart, gatling phasers were installed, as well as hellbore cannons, fusion beams and, of course, the cloaking device. She was the lead ship of the Hydran counterpart.
