Pratt & Whitney, a unit of RTX Corp. (NYSE: RTX), completed a digital technical assessment of its XA103 engine for the U.S. Air Force's Next Generation Adaptive Propulsion program. The assembly readiness review represents a transition from digital design to physical hardware procurement and production.

The XA103 engine uses an adaptive design intended to provide survivability, fuel efficiency, and power and thermal management capabilities for next-generation military platforms. The engine is being developed as part of the Air Force's NGAP program.

"This milestone demonstrates Pratt & Whitney's investment in digital infrastructure, showcasing seamlessly integrated digital capabilities and reinforcing our strong collaboration with the U.S. Air Force," said Jill Albertelli, president of Pratt & Whitney's Military Engines business.

Pratt & Whitney is working with suppliers to procure components needed to assemble the XA103 for testing, which is expected in the late 2020s. The company stated that the engine's performance will exceed current available options.

RTX reported 2025 sales of more than $88 billion and employs over 180,000 people globally. The company is headquartered in Arlington, Virginia.
