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 hopes to revolutionize Army air assault while seamlessly integrating with legacy platforms, proven tactics and existing infrastructure. DEFIANT X is designed to be the fastest, most maneuverable and survivable assault helicopter in history.

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.
