In September 1978, Air Training Command announced project Able Avionic which restructured and consolidated avionics specialists for F-111, F-15, and F-16 aircraft. With the introduction of modular F-100 engines used in the F-15 and F-16 aircraft, new Chanute training courses emerged to keep abreast of the changing equipment students would encounter in the field. The Jet Engine Branch received four J-85 engines during 1983 to familiarize students with engines used in the T-38 pilot trainer aircraft and the F-5 aggressor aircraft.
