AN/UYK-44 Data Processing Set from Submersible NR-1
AN/UYK-44 data processing set from submersible NR-1, in the collection of the U.S. Naval Undersea Museum. NR-1 was the U.S. Navy's first and only nuclear-powered submersible. In service from 1969 to 2008, NR-1 performed missions such as searches, recoveries, oceanographic research, geological surveys, and installation/maintenance of underwater equipment. NR-1 was equipped with two AN/UYK-44 digital computers: a main unit used for navigation and ship control/guidance, and an auxiliary unit used as a backup or scientific computer. AN/UYK-44 computers were also used aboard standard submarines and surface ships.
