DEFIANT X is a complete weapon system that builds on the handling qualities and transformational capabilities proven by the team’s technology demonstrator, the SB>1 DEFIANT®. With unmatched range and survivability, DEFIANT X will change the way the Army fights – by enabling crews to fly low and fast through complex terrain, land quickly, deliver Soldiers and equipment to the objective area (referred to as “the X”) and get out.
DEFIANT X 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 the most survivable platform for mission requirements.
Sikorsky DEFIANT TO Sikorsky/Boeing DEFIANT X
With its rigid coaxial rotor system and pusher propeller, DEFIANT X incorporates Sikorsky X2 Technology™ to operate at high speeds while maintaining low-speed handling qualities. This critical capability provides Soldiers with increased maneuverability and survivability in high-threat air defence environments, allowing them to penetrate enemy defenses while reducing exposure to enemy fire. Compared to the SB>1 DEFIANT, the DEFIANT X airframe has enhancements to improve aerodynamics and reduce the thermal signature.
DEFIANT X will revolutionise the Army’s air assault capability with limited changes in tactics, techniques, procedures, training and infrastructure while maintaining the BLACK HAWK® helicopter footprint and tight formation capability flown today. The Army is expected to release a request for proposal on FLRAA later this year and is planning to award a contract in 2022.
