Development of the aircraft Piasecki X-49 SpeedHawk started by American engineers in the middle of 90-ies, when this helicopter design was developed by the specialists of the company «Sikorsky Aircraft» even earlier, however, for technical reasons, and was not brought to the implementation and serial production. In 2003, the company «Piasecki Aircraft» presented the first demonstration model of the aircraft, further perfecting it, and its first flight helicopter Piasecki X-49 SpeedHawk carried out in the year 2007.

The initiator of the beginning of the development of the helicopter Piasecki X-49 SpeedHawk steel naval forces of the USA, who identified and appropriate financial resources, and voiced the expected characteristics of the aircraft. Initially it was expected that the helicopter will be able to become an effective fighting unit in the US Navy, however, due to the extremely long stay helicopter under development, to be presented later became it has other requirements.

The design of the helicopter Piasecki X-49 SpeedHawk presented quite extraordinary, in particular, instead of the additional stabilizing screw located in the rear of the aircraft, it uses a screw, creating pusher force and inherently increases the speed of flight of the aircraft.

Depending on the intended purpose, the Piasecki X-49 SpeedHawk helicopter can take on board up to 8 people, including two pilots, two airborne gunners, and four military personnel. At the design stage of the helicopter, and its development continues to this day, it was assumed that the aircraft would be equipped with two large-caliber machine guns, as well as a set of unguided missiles, however, in addition to combat purposes, the helicopter could also be used for the needs of search and rescue operations.

The power plant consists of two helicopter gas turbine aircraft engines General Electric T700-GE-701C, capable to disperse the aircraft to 400 km \ h. (Real test allowed to reach speeds in 360 km \ h.), Which makes this aircraft very fast in a turn. Maximum distance of the flight has been defined in 880 kilometers, which also meets the objectives of the proposed operation of the aircraft.

According to official data, the first technical tests helicopter advanced design Piasecki X-49 SpeedHawk be held in the year 2017, in this case, the estimated date of the start of serial production of the aircraft of this model is indicated in 2020 year.
