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. NR-1 was the smallest nuclear submarine ever put into operation. The vessel was casually known as "Nerwin" and was never officially named or commissioned.

NR-1's missions included search, object recovery, geological survey, oceanographic research, and installation and maintenance of underwater equipment. NR-1 had the unique capability to remain at one site and completely map or search an area with a high degree of accuracy, and this was a valuable asset on several occasions.
