American submarine NR-1

Common card · No. 267216

Deep Submergence Vessel NR-1 was a unique United States Navy 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. She was the smallest nuclear submarine ever put into operation, casually known as "Nerwin" and never officially named or commissioned. The U.S. Navy is allocated a specific number of warships by Congress, but Admiral Hyman Rickover avoided using one of those allocations for the construction of NR-1 in order to circumvent the oversight that a warship receives from various bureaus.
