Pratt & Whitney Partners with Leidos for Missile Propulsion

In an exciting development within the aerospace sector, Pratt & Whitney, a division of RTX, has announced its latest partnership with Dynetics, a subsidiary of Leidos. This collaboration focuses on delivering advanced propulsion systems for the Black Arrow Small Cruise Missile, utilizing the highly efficient TJ150 turbojet engines. This contract signifies a critical step in the modernization of defense technologies and aims to address both domestic and international military needs.

About the TJ150 Turbojet Engine

The TJ150 is a compact turbojet engine known for its outstanding performance and reliability. It features a thrust capacity of 150 pounds, enabling it to operate effectively at high altitudes. What sets the TJ150 apart is its rapid manufacturing capability, which allows for scaling production according to demand. This flexibility is crucial for military applications where timeliness and efficiency are paramount.

Chris Hugill, the executive director of Pratt & Whitney GATORWORKS, emphasized the engine's adaptability, stating, "Our TJ150 engines exemplify the modified off-the-shelf solutions we offer for advanced and cost-efficient systems at scale." The company's production capabilities are currently ahead of demands, positioning the TJ150 as a linchpin for high-rate production scenarios.

Integration and Testing Phases

Although initial integration studies began in 2023, concrete work under the current contract commenced in April 2025, with expectations to last until the first quarter of 2026. The contract also includes options for additional engine supplies, illustrating both parties' commitment to long-term collaboration. Notably, the Black Arrow missile's recent successful guided test flight was powered by the TJ150, further validating the engine's performance in real-world conditions.

Mark Miller, the senior vice president for Missile and Aviation Systems at Leidos, commented on the impact of using the TJ150: "Relying on a proven propulsion system like the TJ150 allows our team to concentrate on optimizing the missile design to meet the evolving demands of the strike weapons community." This synergy between engine and missile design represents a significant stride toward improving defense efficiencies.

A Glimpse into Future Developments

Today, the TJ150 is already making waves in multiple missile applications, with over 2,700 units delivered globally to date. This robust production framework is enhanced with innovative practices, including additive manufacturing techniques that not only streamline production but also broaden the supply base. By continuously improving the TJ150 engine, Pratt & Whitney ensures that it meets contemporary military specifications while remaining affordable.

As Pratt & Whitney remains a leader in aerospace technology since its founding in 1925, this new contract with Leidos reaffirms its pivotal role in supporting military operations with their state-of-the-art propulsion solutions. With over 90,000 engines in service, the company is well-equipped to meet the increasing demands of modern aviation and defense systems.

Conclusion

This partnership between Pratt & Whitney and Leidos marks an important milestone in aerospace and defense, indicating a strong movement towards using innovative technologies to address complex challenges. As the industry continues to evolve, the integration of the TJ150 in missile frameworks is likely to usher in new efficiencies and capabilities, playing a significant role in enhancing national security initiatives across the globe.
