SB>1 DEFIANT helicopter achieves first flight

The aircraft is developed by Sikorsky (LM) and Boeing -VIDEO

The Sikorsky-Boeing SB>1 DEFIANT helicopter achieved first flight yesterday at Sikorsky's West Palm Beach, Florida site. This aircraft, developed by Sikorsky, a Lockheed Martin Company, and Boeing, will help inform the next generation of military helicopters as part of the US Army's Future Vertical Lift program.

With its two coaxial main rotors and rear-mounted pusher propulsor, DEFIANT is unlike production rotorcraft available today. It represents a leap forward in technology to achieve the US government's desire for vast increases in speed and range, while improving maneuverability and survivability in a cost-effective way. DEFIANT aircraft's use of X2 Technology will allow the Army to penetrate from strategic standoff and exploit gaps created in complex Anti-Access Area Denial systems against near-peer adversaries. 

The helicopter is participating in the Army's Joint Multi-Role-Medium Technology Demonstrator program. Data from DEFIANT will help the Army develop requirements for new utility helicopters expected to enter service in the early 2030s. X2 Technology is scalable to a variety of military missions such as attack and assault, long-range transportation, infiltration and resupply. DEFIANT is the third X2 aircraft in less than 10 years.
