Pratt & Whitney, an RTX business, has successfully completed a key design milestone for its Pratt & Whitney Valox™ 1500 engine, a new powerplant intended for semi-autonomous collaborative platforms. A comprehensive digital assessment confirms the design is on track to deliver an optimal mix of performance, affordability, and speed to market.
“This milestone reflects Pratt & Whitney’s agility and commitment to delivering critical capability to the warfighter at speed,” said Jill Albertelli, president of Pratt & Whitney’s Military Engines business. “By optimizing the engine design for reduced mission life and moving beyond traditional development timelines, our team is bringing forward a more affordable, scalable propulsion solution for emerging operational needs.”
Leveraging proactive investments in digital engineering, Pratt & Whitney has significantly de-risked the development timeline and is now focused on maturing the design for follow-on ground testing. In late 2025, Pratt & Whitney received a contract award valued at more than $10 million from the U.S. Air Force to advance the engine design.
Pratt & Whitney recently unveiled the Pratt & Whitney Valox™ engine family , which is engineered to deliver the speed, precision, and affordability required for modern collaborative combat systems and a broad range of emerging applications.
