- Central Computer for aircraft Saab 37, Viggen
Bengt Jiewertz

At the end of the 1950s it was decided that the multipurpose attack/fighter Saab 37 Viggen should be designed as a single seat aircraft. A central computer and a head-up display made it possible to dispense with the need for a human navigator. The computer was the central computing and integrating unit for all electronic equipment to support the pilot.
This computer, CK37 used in the Saab AJ37, was the first airborne computer in the world to use integrated circuits (first generation ICs). Almost 200 computers were delivered 1970 -1978. The function was reliable and the computers were still in operation, with upgrades, at the early beginning of 2000`s. (pdf-file).
