Control Data AN/AYK-14(V)
Donated by Frank Hajdu
The AN/AYK-14(V) is a conduction cooled airborne computer that was designed in 1976 by the Control Data Aerospace Division in Bloomington, MN. It has a microprogrammed 16-bit CPU based on AMD 2900 series ICs that can use 4, 8, 16, or 32-bit data. The processor runs between 0.3 and 2.3 MIPS depending on the instruction mix. The instructions are a superset of the AN/UYK-20 computer and it can run AN/UYK-20 software. SInce it is an airborne computer it is designed for use at altitudes up to 70,000 feet and temperatures from -54C to 71C.
The AN/AYK-14(V) design was started in 1976, and the original price was $185,000. It was designated the US NAVY's Standard Airborne Computer in 1986. The processor design was upgraded in 1987, with a single SCP board replacing the previous three CPU, GPM, and EAU boards, and delivering 2x the performance and 8x the memory. In 1991 the processor was upgraded again, the VPM delivering 18 MIPS.
The CDC division was acquired by General Dynamics Advanced Information Systems. Over 10,000 of these computers have been made. The AN/AYK-14(V) is still in use in many aircraft, including the F/A-18A-F, SH-60B, E-2C, AV-8B, A-6F, EA-6B, F-14D, S-3, EP- 3, V-22, ACLS, and the MK-50 Torpedo.
