Key Features: Developed on the experience of the Defiant, the Defiant X boasts two rigid coaxial rotors and a pusher propeller for high-speed capabilities. Achieved a speed of 211 knots in straight-and-level flight, setting the stage for speeds exceeding 250 knots, meeting the U.S. Army’s desired criteria.

Twice the range and speed of the UH-60 Black Hawk, positioning it as “the fastest, most maneuverable and most survivable assault helicopter in history.” Purpose-built for a modernized Army, providing expanded reach, survivability, and lethality in a multi-domain battle space. A new engine, the Future Affordable Turbine Engine (FATE), is to meet the radius requirement of 424 km.


Compared to conventional helicopters, the counter-rotating coaxial main rotors and pusher propeller offer a 343 km/h speed increase, a 60% combat radius extension, and 50% better performance in high-hot hover operations. Design Enhancements: Improved aerodynamics with a refined shape and a new angled nose. Reduced thermal signature with a redesigned exhaust system. New front landing gear and transformed tricycle landing gear configuration for enhanced stability.
