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

edit

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

edit

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]
