Lockheed Martin Offering Defiant, Raider Technology to NATO Countries
The Sikorsky SB>1 Defiant and S-97 Raider helicopters would bring new rotorcraft technology to NATO member countries.

Lockheed Martin's Sikorsky unit plans to offer to NATO countries the technology on the SB>1 Defiant and S-97 Raider helicopters that it has developed for the U.S. Army’s Future Vertical Lift (FVL) program, the company said at the Farnborough Airshow.

The company has branded its advances for the FVL as X2 Technology. The design includes compound co-axial main rotors, power shift between the main rotor and the propeller, and reverse thrust on the latter. The propeller can also be switched on and off, and both it and the main rotor can reduce speed into a quieter "whisper mode" for greater tactical surprise.
