Pratt & Whitney, an RTX business, has completed a critical assessment of its Next-Generation Adaptive Propulsion (NGAP) offering with the US Air Force, moving the program closer to completing its detailed design review. The team is now working towards ground testing of its NGAP prototype, referred to as XA103, which is expected to occur in the late 2020s. The engine will enhance performance that is key to enabling future air dominance capabilities, which are needed to ensure the US Air Force achieves air superiority and deters pacing challenges.NGAP technologies will provide advanced survivability, fuel efficiency, and robust power and thermal management. These are necessary to enable the required range, weapon and sensor capability, and persistence future air dominance platforms will require to meet evolving operational needs.
