Deep Submergence Vessel NR-1 was a unique United States Navy (USN) nuclear-powered ocean engineering and research submarine, built by the Electric Boat Division of General Dynamics at Groton, Connecticut. NR-1 was launched on 25 January 1969, completed initial sea trials 19 August 1969, and was home-ported at Naval Submarine Base New London.
Richard's operational assignments include command of USS Parche (SSN-683) as well as Submarine NR-1, then the United States Navy's only nuclear-powered, deep-submergence submarine. He also served aboard USS Portsmouth (SSN-707) , USS Asheville (SSN-758) and USS Scranton (SSN-756) .
All DSVs to date (2023) are dependent on a surface support ship or a mother submarine that can piggyback or tow them (in case of the NR-1) to the scene of operations. Some DSRV vessels are air transportable in very large military cargo planes to speed up deployment in case of emergency rescue missions.
MV Carolyn Chouest is a chartered support ship for the United States Navy that was originally assigned to the Special Missions Program to support NR-1, the deep submergence craft. She towed NR-1 between work areas, served as a floating supply warehouse and provided quarters for extra crew until the NR-1 was removed from service in 2008. Since ...
The Deep Submergence System Project was established in June 1965 in the aftermath of the loss of USS Thresher in 1963. At the time, submarine operating depths greatly exceeded the capabilities of rescue vessels. Lockheed Missiles and Space Company was contracted to produce a deep diving rescue
The old adage that nearly three-quarters of the ocean floor is unreachable is no longer true.
Like most deep submergence vehicles, Alvin is normally transported on board its support vessel. It is launched shortly before a dive, and recovered after the dive, using a suitable launch and recovery system (LARS) mounted on the support vessel. The support vessel is usually the R/V Atlantis, but several others have been used.
