Deep Submergence Rescue Vehicle - DSRV

Deep Submergence Rescue Vehicles perform rescue operations on submerged, disabled submarines of the U.S. Navy or foreign navies.

DSRV’s are designed for quick deployment in the event of a submarine accident. DSRV’s are transportable by truck, aircraft, ship, or by specially configured attack submarine. At the accident site, the DSRV works with either a “mother” ship or “mother” submarine. The DSRV dives, conducts a sonar search, and attaches to the disabled submarine’s hatch. DSRV’s can embark up to 24 personnel for transfer to the “mother” vessel.

 DSRV’s were developed as a result of the USS Thresher submarine accident in 1963, when all hands were lost. At the time, submarine operating depths greatly exceeded the capabilities of rescue vessels. The Deep Submergence Systems Project contracted with Lockheed Missiles and Space, Co. to produce a deep diving rescue submarine, the first of which was launched in 1970.
