The DEFINAT X will feature a rigid coaxial rotor system and pusher propeller.
Sikorsky and Boeing have released details of their advanced helicopter for the U.S. Army's Future Long-Range Assault Aircraft competition, known as FLRAA. They say that the aircraft, named DEFIANT X, will be the fastest, most maneuverable and most survivable assault helicopter in history and that it will revolutionize the way the Army meets threats in 2035 and beyond.
It will feature a rigid coaxial rotor system and pusher propeller.
DEFIANT X is a complete weapon system that builds on the handling qualities and transformational capabilities proven by the team's technology demonstrator, SB>1 DEFIANT.
The new model will fly 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.
"We are ready to deliver unparalleled capabilities backed by proven technologies that will truly transform the Army's mission today, with room to grow and adapt to the missions of tomorrow," says Andy Adams, Sikorsky vice president of Future Vertical Lift. "DEFIANT X not only includes the transformational aircraft – a maneuverable, survivable, lethal weapon system – it also leverages Sikorsky's and Boeing's advanced manufacturing capabilities."
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 defense environments, allowing them to penetrate enemy defenses while reducing exposure to enemy fire. Compared to SB>1 DEFIANT, the DEFIANT X airframe has enhancements to improve aerodynamics and reduce the thermal signature.
"DEFIANT X is purpose-built for a modernized army that requires expanded reach, survivability and lethality," says Steve Parker, vice president and general manager of Boeing Vertical Lift. "This weapon system will give soldiers unequaled technological advantage and connectivity over adversaries in a multi-domain battle space."
Sikorsky believes that the DEFIANT X will revolutionize 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, with a contract award expected in 2022.
