Submarine Rescue Diving and Recompression System (SRDRS)

Submarine Rescue Diving and Recompression System performs rescue operations on submerged, disabled submarines of the U.S. Navy or foreign navies. SRDRS replaced the Deep Submergence Rescue Vehicles (DSRVs) in 2008.
SRDRS is designed for quick deployment in the event of a submarine accident. SRDRS is transportable by truck, aircraft or ship. At the accident site, the SRDRS works with a "mother ship." The SRDRS is a tethered, remotely-operated vehicle that placed into the water and attaches to the disabled submarine's hatch. SRDRS can embark up to 16 rescued personnel for transfer to the "mother" vessel.

The SRDRS consists of three systems:

1. Assessment/Underwater Work System (AUWS). Includes the one-atmosphere diving system (ADS2000) for assessment of a disabled sub and rescue hatch clearance down to 2000 FSW. These are in the process of being replaced by Remote Operated Vehicles (ROVs).
2. Submarine Rescue System - Rescue Capable System (SRS-RCS). RCS Pressurized Rescue Module (PRM) provides a tethered, remotely-operated vehicle capable of rescuing 16 personnel per trip.
3. Submarine Decompression System (SRS-SDS). Will provide a transfer-under-pressure capability for hyperbaric treatment of sailors rescued from a pressurized sub. IOC is planned for FY17.
4. Government owned, contractor operated and maintained.
SRDRS was developed due to the retirement of DSRVs. DSRVs 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. SRDRS was contracted with Phoenix International in 2005 and SRS-RCS was delivered to the fleet in 2008.
