AN/UYK-43

< AN

The AN/UYK-43 was the standard 32-bit computer of the United States Navy for surface ship and submarine platforms, with the first unit delivered in October, 1984. Some 1,250 units were delivered through to 2000. The size of a refrigerator, it replaced the older AN/UYK-7, both built by UNISYS and shared the same instruction set. An enhancement to the UYK-43, the Open Systems Module (OSM), allows up to six VMEbus Type 6U commercial off-the-shelf (COTS) cards to be installed in a UYK-43 enclosure.

In accordance with the Joint Electronics Type Designation System (JETDS), the "AN/UYK-43" designation represents the 43rd design of an Army-Navy electronic device for general utility data processing computing equipment. The JETDS system also now is used to name all Department of Defense electronic systems.

The UYK-43 is being replaced by commercial off-the-shelf systems. Retired systems are being cannibalized for repair parts to support systems still in use by U.S. and non-U.S. forces.
