The AN/UYK-44 was the standard 16-bit minicomputer of the United States Navy developed in the early 1980s by Sperry Corporation and was completed in early 1984. The AN/UYK-44 was used in surface ships, submarines, ground C4I platforms, radar and missile control systems.AN/UYK-44 Computer The system was designed to replace the older AN/UYK-20 model.
In accordance with the Joint Electronics Type Designation System (JETDS), the "AN/UYK-44" designation represents the 44th 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.
Technical specifications The AN/UYK-44 had 2 million words of memory, approximately 4 MB in modern terms, and operated at 0.9 MIPS.IEEE Global History Network - "First-Hand:Legacy of NTDS - Chapter 9 of the Story of the Naval Tactical Data System"
The system has relatively large I/O capability and has a MIL-STD-1397 point-to-point I/O bus running at 250K words/s.Glenn's Computer Museum - Later Military (AN/UYK-44 Shipboard Computer) The system was built around the use of "Standard Electronic Modules" (SEM) for logic implementation. These modules had double-sided surface mount integrated circuits and ceramic substrates for interconnect and cooling.VIP Club - "Introduction to 16-Bit Computers" (Descriptions)
