The Sikorsky-Boeing SB>1 Defiant helicopter successfully completed its first flight on Thursday. The aircraft was developed by Lockheed Martin subsidiary Sikorsky in partnership with Boeing to be part of the U.S. Army's Future Vertical Lift program. It was designed using technology developed from Sikorsky's X2 Technology Demonstrator, which won the Collier Trophy in 2010. Features include active vibration control, a rigid rotor system, pusher prop, fly-by-wire flight controls and composite fuselage.
