S-97 RAIDER to Enhance Army's Flight Capabilities

Sikorsky's game-changing helicopter prototype improves agility at high and low speeds

As Sikorsky Aircraft reaches the assembly midpoint of its self-funded S-97 RAIDER helicopter prototype, the Army National Guard could anticipate a game-changing evolution in its future aviation capabilities. The RAIDER helicopter’s coaxial counter-rotating rigid rotor blades combined with a pusher propeller will offer dramatic improvement in performance (speed, altitude, range and maneuverability) compared to traditional armed reconnaissance helicopters. Never-before-seen precision agility at both high and low speeds is expected to significantly change how the Guard could fly and fight. Sikorsky is readying its RAIDER prototype for flight demonstrations in 2015.
