Lockheed AH-56 Cheyenne

Lockheed AH-56 Cheyenne is an American attack helicopter developed by Lockheed Corporation in 1967.

The design of the strike helicopter model Lockheed AH-56 Cheyenne began by American aircraft manufacturers from the company “Lockheed Corporation” in the early ’60s. The US armed forces urgently needed high-quality, high-performance and low-cost combat helicopters, in connection with which the leadership of the American aircraft company decided to create the corresponding helicopter, however, although the project turned out to be very effective, the US military command decided the use of more functional attack helicopters from the aircraft manufacturer Sikorsky Aircraft, which, among other things, turned out to be even more reliable in terms of their operation.

The first test tests of the Lockheed AH-56 Cheyenne model helicopter took place in the third decade of September 1967, while the aircraft successfully passed them, however, the project was not able to reach the criteria of the US Armed Forces, moreover, the production of helicopters was very costly, which also did not provide profitability in cooperation with Lockheed Corporation.

The Lockheed AH-56 Cheyenne helicopter has very acceptable flight and combat qualities, however, the rather large dimensions of this aircraft deprive it of proper maneuverability, which by no means always proved to be effective in the fight against large enemy forces. In service with the Lockheed AH-56 Cheyenne helicopter are:

  • 40 mm. 7.62 mm grenade launcher or machine gun .;
  • 30 mm. automatic aircraft gun;
  • A set of unguided missiles to combat ground targets;
  • A set of guided missiles to combat ground targets.

The crew of the Lockheed AH-56 Cheyenne helicopter consists of two people – a pilot and a gunner, and, because the helicopter belongs to the class of combat attack aircraft, transportation of people and goods on board is not possible.

The power plant of the Lockheed AH-56 Cheyenne aircraft consists of one General Electric T64-GE-16 gas turbine aircraft engine, which has a power of 3925 hp allows the helicopter to accelerate to a maximum speed of 390 km \ h. The maximum flight range of this aircraft is 1970 kilometers, which, in essence, provided the helicopter with a large combat radius of its action, and was one of the most important advantages of this aircraft.

Even though the helicopter project was canceled very quickly, 10 copies of this attack aircraft were still produced, however, to date, these aircraft are part of museum exhibits.
