AN/UYK-7

The AN/UYK-7 was the standard 32-bit computer of the United States Navy for surface ship and submarine platforms, starting in 1970.^[1][2] It was used in the Navy's NTDS^[2] & Aegis combat systems and U.S. Coast Guard,^[3] and the navies of U.S. allies.^[4] It was also used by the U.S. Army.^[5]

Technical

Built by UNIVAC, it used integrated circuits, had 18-bit addressing and could support multiple CPUs and I/O controllers. Three CPUs and two I/O controllers were a common configuration. Its multiprocessor architecture was based upon the UNIVAC 1108.^[4] An airborne version, the UNIVAC 1832, was also produced.

Replacement

In the mid-1980s, the UYK-7 was replaced by the AN/UYK-43 which shared the same instruction set.^[1] Retired systems are being cannibalized for repair parts to support systems still in use by U.S. and non-U.S. forces.^[6]
