GPA-37

GPA-37 Course Directing Group - A Weapons Directing Analog Computer system built by General Electric Corporation, Heavy Military Electronic Equipment Department. Established at ten Air Force long-range radar sites in the late 1950s to automate the manual Ground Control Intercept (GCI) mission against Soviet Manned Bomber attacks. An eleventh system was established at Keesler, Air Force Base for training. The GPA-37 was meant as an interim system at most radar sites and was removed soon after the FST-2 went operational on a site.
