For decades, the America has enjoyed a near-unrivaled position when it comes to developing and fielding high performance, incredibly reliable military jet engines. No matter how capable an airframe or the associated mission systems, these attributes are of little benefit absent the performance advantages afforded by a capable jet engine. The U.S. Air Force is at a key inflection point when it comes to stewarding this technology. Much of the service’s aircraft inventory is flying with engines designed in the Cold War. Newer types designed in the 1990s and 2000s are now multiple decades old. Sustaining existing designs is different from developing, fielding, and producing new technology.  The Air Force knows this and that is why it has invested in multiple programs to pursue new engines that deliver enhanced performance, reliability, and efficiency attributes necessary to meet current and future mission requirements. We discuss jet engine innovation from the perspective of AFRL and industry—reflecting the partnership that delivers this technology.
