WASHINGTON — The Air Force’s next-gen engine protype effort is facing a two-year delay and will not complete before fiscal 2030, the service confirmed today to Breaking Defense.
Under the Next Generation Adaptive Propulsion (NGAP) program, engine makers GE Aerospace and RTX subsidiary Pratt & Whitney are currently fabricating dueling engine designs, work that FY25 budget documents show was expected to wrap up in the fourth quarter of FY27. However, in FY26 documents released by the Trump administration in June, that timeline has shifted by over two years to the second quarter of FY30.
Asked about the delay, an Air Force spokesperson said, “The updated schedule in the budget documents reflects supply chain challenges encountered by the program.”
In a statement, a spokesperson for GE Aerospace said that the company “is executing the NGAP contract schedule as proposed.” GE has also expressed confidence that the program could be accelerated.
