RTX’s Pratt & Whitney secures contract from Dynetics

Pratt & Whitney, an RTX (RTX) business, has secured a contract from Dynetics, a Leidos (LDOS) 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. 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.
