NR-1 control room equipment in the collection of the U.S. Naval Undersea Museum. From left to right, the control panels shown are sonar, ballast and trim/auxiliary control/ship's status, ship's control display, heading and speed/obstacle avoidance sonar, camera status display, and communications. NR-1 was the U.S. Navy's first and only nuclear-powered submersible, equipped with a miniature reactor that allowed her crew to remain submerged for up to 30 days at a time. During her 39-year career, NR-1 performed missions such as searches, recoveries, oceanographic research, geological surveys, and installation/maintenance of underwater equipment. Highlights include finding and recovering a lost missile from the ocean floor in 1976 and investigating the remains of Civil War ironclad USS Monitor in 2002. Most prominently, NR-1 searched for, identified, and raised components of Space Shuttle Challenger after it exploded over the Atlantic Ocean in 1986.
