RTX's Pratt & Whitney to provide affordable mass propulsion for Leidos' Small Cruise Missile program

TJ150 turbojet engines will power the multi-use Black Arrow missile 

PARIS, June 16, 2025 /PRNewswire/ -- Pratt & Whitney, an RTX (NYSE: RTX) business, has secured a contract from Dynetics, a Leidos company, to supply TJ150 engines to be integrated with their Small Cruise Missile, known as Black Arrow.

The TJ150 is a compact, high performance turbojet engine that can be manufactured quickly. It has proven reliability and scalability in both production and size. With 150-pounds of thrust, it can light and operate at high altitudes and is designed to power a variety of autonomous systems and weapons for domestic and international customers.    

"Our TJ150 engines exemplify the modified off-the-shelf solutions that Pratt & Whitney has available for advanced and cost-efficient effectors at scale," said Chris Hugill, executive director of Pratt & Whitney GATORWORKS. "Production capacity is in place today, ahead of demand, which strongly positions our TJ150 engine for a range of high-rate production scenarios."

Although preliminary integration studies with Pratt & Whitney commenced in 2023, work under this current contract began in April 2025 and will run through the first quarter of 2026. There is an option to provide follow-on quantities of engines. The TJ150 is in production today, and Pratt & Whitney is continuing to improve upon the engine with a focus on affordability.

"Black Arrow completed a successful guided test flight, powered by the TJ150, late last year," said Mark Miller, senior vice president for Missile and Aviation Systems at Leidos. "The ability to rely on a proven propulsion system like the TJ150 frees up our team to focus on optimizing the missile to meet the needs of the strike weapons community."

Today, the TJ150 powers several missile applications, with over 2,700 delivered to customers globally. Pratt & Whitney is applying additive manufacturing to the engine to offer the same robust, reliable engine, while providing production flexibility and expanded supply base solutions.
