LONDON — At the Farnborough International Airshow, Pratt & Whitney said it has completed a key design milestone for its Valox 1500 engine, a powerplant intended for semi-autonomous collaborative platforms. A comprehensive digital assessment indicates the design is tracking toward a 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.”
The company said proactive investments in digital engineering have reduced development risk, and efforts now shift to maturing the design ahead of 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 Valox engine family, which it says is engineered to deliver the speed, precision, and affordability required for modern collaborative combat systems and a broad range of emerging applications.
