U.S. Air Force pays $148M to keep 1960s jet engine flying

The U.S. Air Force and Defense Logistics Agency have awarded Collins Engine Nozzles two sole-source contracts worth a combined $148.3 million for fuel-system components supporting the J85 engine. The turbojet has powered the T-38 trainer since the 1960s, so the awards are intended to keep the aging fleet serviceable as the Air Force transitions toward newer training aircraft. Performance periods extend into 2029 and 2032, reflecting continued sustainment demand, while the contracts cover parts and support rather than a redesign of the engine or a new propulsion program.
