The AN/UYK-7 was the standard
32-bitcomputer of the United States Navyfor surface shipand submarineplatforms, starting in 1970. [http://vipclubmn.org/milestones.aspx Milestones ] ] It was first used in the Navy's Aegis combat system, but was later employed in a variety of ships of the U.S. Navy, U.S. Coast Guard[ [http://www.uscg.mil/directives/ci/8000-8999/CI_8274_1A.pdf AN/UYK-7 MAINTENANCE ASSIST MODULE (MAM) KITS ] ] , and the navies of U.S. allies. [ [http://www.cc.gatech.edu/~randy/folklore/v3n2.html Unisys History Newsletter] ] It was also used by the U.S. Army. [ [http://www.sed.monmouth.army.mil/comm/dds/EPLRS.htm CECOM SEC Communications Software Engineering Support Division ] ] 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). And airborne version, the UNIVAC 1832, was also produced.
In the mid-1980s, the UYK-7 was replaced by the
AN/UYK-43which shared the same instruction set. Retired systems are being cannibalized for repair parts to support systems still in use by U.S. and non-U.S. forces. [ [http://www.chips.navy.mil/archives/98_apr/Legacy.htm Logistics Support for Legacy Systems: ] ]
