The XR-4 made its first flight Jan. 14, 1942, with Sikorsky’s test pilot, Les Morris, at the controls.

Detailed explanation-2: -The Army’s helicopters have a number of names you’ll recognize immediately: Apache Attack Helicopter AH-64D/E. Black Hawk Utility Helicopter UH/HH-60. Cheyenne Attack Helicopter AH-56.

Detailed explanation-3: -The French Army was one of the first military forces to modify and use helicopters in combat in a ground attack role during the Algerian War of 1954–62. In 1955, French field commanders placed infantry machine gunners in the stretcher panniers of their Bell 47 (Sioux H-13) casualty evacuation helicopters.

Detailed explanation-4: -Their Bell UH-1 “Huey” helicopters became worldwide icons of the U.S. Army.
