F-20 Tigershark Integrated Digital Avionics

The F-20A integrated avionics system provided air to air and air to ground target detection and weapons delivery for supersonic intercept, air superiority, combat air patrol, close air support, and interdiction missions----day or night and under adverse weather conditions.
The avionics design simplified pilot operations, reduced pilot workload, and rapidly provided data for successful combat missions. The design incorporated the newest USAF avionics standards. Primary avionics elements were integrated through a redundant MIL STD 1553B multiplex data bus and controlled by a MIL STD 1750A mission computer using MILSTD 1589 Jovial J 73 language. The computer contained 256,000 words of programmable memory and had a throughput of 1 million operations per second. The computer had a specified MTBF of 2400 hours. The F-20A was able to accept new MIL STD avionics and weapons with a minimum of modification and without additional wiring to the avionics.
