Sikorsky President Jeffrey Pino describes the Raider X2 Helicopter during the launch event in October.

Sikorsky Aircraft announced plans to design, build, and fly two prototype light tactical helicopters as the follow-on advancement to the X2 Technology demonstrator aircraft that unofficially shattered the helicopter world speed record in September with a flight speed of 250 kt. The decision to continue development of the next-generation rotary wing technology will enable Sikorsky and select suppliers to offer the X2 prototype vehicles for flight test and evaluation by U.S. armed forces. The two prototypes being manufactured have been designated Raider X2 helicopters. Like the X2 Technology demonstrator, the X2 Raider prototypes will feature twin coaxial counter-rotating main rotors (in place of one main rotor and a tail rotor) and a pusher propeller. For the armed reconnaissance mission, the X2 Raider will have space aft of the two-pilot cockpit for armament and auxiliary fuel. In an assault configuration, the cabin affords space to accommodate up to six troops. The company expects to conduct its first major program milestone—a preliminary design review—in 2011.

Thermal imaging data obtained from a FLIR high-performance camera shows that the expected turbine output temperature is approximately 285°C when the helicopter is in forward flight. However, during hover operations a steady state temperature of about 343°C will be reached.
