AN/UYK-7 Computer Set

Note: This is an initial 3D model that has not undergone post-processing work due to the COVID-19 pandemic. As such, the model contains small inaccuracies: some geometry/components are distorted or blurred.

AN/UYK-7 computer set in the collection of the U.S. Naval Undersea Museum. The AN/UYK-7 was the first computer used with the MK 113 and MK 117 fire control and sonar systems aboard Los Angeles-class submarines. Placed in service in the 1970s, the AN/UYK-7 could hold 100 kilobytes of memory in its magnetic core — an extremely high capacity at the time, but about a million times smaller than the capacity of a modern iPhone. By the mid-1980s, the more advanced AN/UYK-43 had replaced the AN/UYK-7. The Navy continued to maintain a small number of AN/UKY-7 units into the late 2010s, however, as backup units for the Tomahawk fire control systems in use aboard submarines USS Dallas (SSN 700) and USS La Jolla (SSN 701). These two AN/UYK-7 units are believed to be among the only examples still in existence today.
