American Submarine NR-1

American Submarine NR-1

The Deep Submergence Vessel NR-1 was a unique United States Navy nuclear-powered ocean engineering and research submarine. It was built by the Electric Boat Division of General Dynamics at Groton, Connecticut. It was launched on 25 January 1969, completed its initial sea trials 19 August 1969, and was home-ported at Naval Submarine Base New London. Casually known as "Nerwin", NR-1 was never officially named or commissioned. The U.S. Navy is allocated a specific number of warships by the U.S. Congress. Admiral Hyman Rickover not only avoided using one of those allocations, but he also wanted to avoid the oversight that a warship receives from various bureaus.
