Pratt & Whitney Speeds Up Next-Gen Fighter Engine XA103 Development

Pratt & Whitney is accelerating development of its XA103 adaptive engine for the US Air Force's Next Generation Air Dominance (NGAD) fighter. The company has doubled data delivery rates, fostering constant collaboration through model y-based design. The engine is expected to test in the late 2020s, with the Assembly Readiness Review as the next major milestone.

The XA103 is one of two adaptive-cycle engines under development for the USAF's Next Generation Adaptive Propulsion (NGAP) programme, competing against GE Aerospace's XA102 engine. Pratt & Whitney is leveraging advanced digital data packages to shorten development times, reduce costs, and increase design efficiency. The company has self-invested over $30 million this year to further develop its model y-based environment for the XA103 engine.

The NGAP programme builds on lessons learned from the Adaptive Engine Transition Program (AETP), with the XA103 tailored specifically for NGAD's performance requirements. The development goal is to enhance speed, accuracy, and design efficiency through advanced digital model y-based design and collaboration across engineering and manufacturing processes.

The XA103 engine is expected to test in the late 2020s, with the Assembly Readiness Review as the next key step. Pratt & Whitney's investment in digital technologies and collaboration is aimed at reducing costs and shortening development timelines, while enhancing the engine's performance and adaptability for the NGAD fighter.
