The Scorpio (Submersible Craft for Ocean Repair, Position, Inspection and Observation) is a brand of underwater submersible Remotely Operated Vehicle (ROV) manufactured by Perry Tritech used by sub-sea industries such as the oil industry for general operations, and by the Royal Navy and the United States Navy for submarine rescue services. Originally developed by AMETEK Straza of El Cajon, California, they were subsequently developed by Perry Tritech. Although the design of the original Scorpio is over several decades old, it forms the basis for a current generation of Scorpio-branded ROVs. Scorpio ROVs are named in a sequence following the order of manufacture, such as "Scorpio 17" or "Scorpio 45" which refer to specific ROVs.
