Lockheed Martin, February 14, 2022 - PHILADELPHIA, PA — Sikorsky, a Lockheed Martin Company and Boeing 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.
“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 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.”
Defiant X is a complete weapon 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.
“Honeywell is excited to be a part of Team Defiant and proud to play a part in the future of vertical lift for the U.S. Army,” said Ricky Freeman, president, Defense & Space at Honeywell Aerospace. “We’re confident our HTS7500 engine on the Defiant X platform will provide the Army with an agile, fast and maneuverable platform that will help ensure overmatch capability in the future battlespace.”
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.
About Sikorsky and Boeing: Together, Sikorsky and Boeing (NYSE: BA) 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.

Honeywell Selected By Lockheed Martin Sikorsky-Boeing to Power Defiant X Helicopter in Key U.S. Army Pursuit
Honeywell - February 10, 2022 - PHOENIX - Honeywell has been selected to provide its new HTS7500 turboshaft engine as the power behind the Lockheed Martin Sikorsky-Boeing Defiant X® helicopter, currently a contender to win the U.S. Army’s Future Long-Range Assault Aircraft (FLRAA) competition.
The HTS7500 turboshaft engine is the newest and most technologically advanced model in Honeywell’s family of military engines, which includes the iconic T55 engine that has powered the H-47 fleet for over 60 years.
Like the T55, the HTS7500 is a highly reliable engine designed to thrive in austere environments and to perform to keep military personnel safer. The HTS7500 enhances mission readiness and exceeds mission power and fuel consumption requirements.
The new engine comes equipped with a modernized control system, which enables a highly secure flow of engine data. The control system improves operating capabilities, reduces life-cycle costs, and ensures engine health status through its digital thread road map.
“This engine builds upon the battle-proven architecture of the T55, but the HTS7500 takes engine performance, reliability and efficiency to a whole new level,” said, Dave Marinick, president, Engines and Power Systems, Honeywell Aerospace. “The engine is structurally similar, which is great for maintainers in the field because they can use current tools and training. However, when it comes to performance, the HTS7500 is 42% more powerful than the T55-GA-714A and has the lowest total weight compared to other engines in its horsepower class.”
“We’re committed to the U.S. Army’s focus on modernization and multidomain operations, and the selection of Honeywell’s latest engine technology for the Defiant X® is proof of that commitment,” said Ricky Freeman, president, Defense and Space, Honeywell Aerospace. “The HTS7500 checks all the right boxes for the Lockheed Martin Sikorsky-Boeing team and the Army, and we are excited to play a part in the future of vertical lift for our Army customer and Team Defiant .”
The Defiant X® will be the fastest, most maneuverable assault helicopter in history. It can fly two times faster and farther than the Black Hawk and is currently being tested in a digital combat environment, where it continues to prove its unmatched range and survivability.
FLRAA was initiated by the U.S. Army in 2019 to develop a new utility helicopter that will replace the Sikorsky UH-60 Black Hawk starting in 2030. The Black Hawk was developed in the 1960s and 1970s and was selected by the U.S. Army in 1976. FLRAA will provide the next generation of capability for decades to come for the U.S. Army, and the HTS7500 has been built to provide world-class reliability and time on wing for this next generation of aircraft.
Engines designed by Honeywell have been at the forefront of aircraft propulsion for nearly seven decades, shaping aviation’s progress in civilian and military applications around the world. Honeywell’s high-performance, high-power engines combine rigorous testing with rugged design, ensuring smoother operation in the harshest environments. Continuous improvement programs have resulted in engines that today provide more power with lower fuel consumption, enhanced safety and proven reliability.
