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. It was used in the Navy's Aegis combat system and U.S. Coast Guard[2], and the navies of U.S. allies.[3] It was also used by the U.S. Army.[4] Built by UNISYS, it used integrated circuits, had 18-bit addressing and could support multiple CPUs and I/O controllers (3 CPUs and 2 I/O controllers were a common configuration). Its multiprocessor architecture was based upon the UNIVAC 1108. An airborne version, the UNIVAC 1832, was also produced.
