Air Force pushes Next Generation Adaptive Propulsion (NGAP) prototyping completion to 2031, extending schedule by 3 years
The USAF’s Next Generation Adaptive Propulsion (NGAP) programme is now expected to finish its prototyping work in 2031—about a three-year slip versus earlier forecasts. The update adds schedule risk to adaptive-cycle engine maturation that underpins potential sixth-generation and related propulsion pathways.
