Boeing-Lockheed Martin Sikorsky Selects Honeywell HTS7500 Turboshaft Engine to Power DEFIANT X

Boeing and Sikorsky, a Lockheed Martin Company announced Honeywell as the engine provider for DEFIANT X, the advanced helicopter for the U.S. Army’s Future Long-Range Assault Aircraft (FLRAA) competition. With Honeywell providing the HTS7500 turboshaft engine, Team DEFIANT brings unsurpassed Army Aviation experience to revolutionize Army air assault while seamlessly integrating with legacy platforms, proven tactics and existing infrastructure. DEFIANT X® will be the fastest, most maneuverable and survivable assault helicopter in history.

“DEFIANT X® is a transformational aircraft, and Honeywell is giving us a transformational engine to power it,” said Paul Lemmo, president of Sikorsky. “DEFIANT X® is optimized for operational effectiveness, sustainment and interoperability with the enduring fleet, and will transform the Army.” “Team DEFIANT’s strength is built on the experience of Sikorsky and Boeing, and a commitment to Army Aviation,” said Mark Cherry, vice president and general manager of Boeing Vertical Lift. “Honeywell’s history with Boeing and the U.S. Army makes us even more confident that DEFIANT X® is the best fit for the Army’s total mission.”

DEFIANT X® is a complete ωεɑρσռ system that builds on the handling qualities and capabilities proven by the team’s technology demonstrator, SB>1 DEFIANT®. It flies twice as far and fast as the venerable Black Hawk helicopter it is designed to replace. Currently undergoing testing in a digital combat environment, the aircraft continues to prove itself as the most survivable platform for mission requirements. Sikorsky-Boeing submitted the proposal for DEFIANT X® for the U.S. Army’s Future Long-Range Assault Aircraft in September 2021. Contract award is expected this year.

Together, Sikorsky and Boeing have built 90 percent of the U.S. Army’s current military rotorcraft and have totaled more than 15 million flight hours. We’re the team that has brought forward iconic military rotorcraft including: Black Hawk, Chinook and Apache. The iconic UH-60 Black Hawk has proven itself to be the premiere assault platform in the world and DEFIANT X® will bring the next level of capability that the Future Long-Range Assault Aircraft requires.
