The United States Air Force (USAF) owns approximately 2,300 TF33 engines of various models that it uses on seven weapons systems, mainly the KC-135, E-3 Advanced Warning and Control Systems (AWACS), B-52, and E-8 (Joint Surveillance and Target Attack Radar System (JSTARS)) aircraft (Parker, 2006). Designed in the 1950s and manufactured in the 1960s and 1970s, the TF33 is one of the oldest engine families in the USAF inventory. Given their age and number, TF33-powered aircraft have been the subject of numerous re-engining studies over the years (at least nine studies since 1984), one executed reengining program (the conversion of most earlier KC-135s to the KC-135R model), and one in-progress program (re-engining of the E-8).

The USAF held a TF33 Industry Day on 16 October 2018 at the Tinker Industrial Business Park to tell contractors what it needs to support these engines moving forward.  The just-posted, 87-page briefing to industry is here.
