The future super helicopter of the US military.

The Piasecki X-49 SpeedHawk is considered one of the future trends in US military helicopter development. Speed, stability, maneuverability, and extremely advanced electronics are the advantages of this helicopter.

The Piasecki X-49 "SpeedHawk" helicopter is a version developed by Piasecki Aircraft, with aerodynamic modifications aimed at providing performance advantages in the context of the modern battlefield.

The X-49A is built on the airframe of the well-known Sikorsky 60 Seahawk helicopter, but changes to the tail rotor arrangement result in improved performance and maneuverability compared to its predecessors. The addition of two large wings provides increased lift and allows for the attachment of weapon pylons when needed.
