The Vietnam War was the first armed conflict in which the helicopter played a key role, both as a transport and combat aircraft. Taking part in many battles, the US Army and US Marines massively used different types of helicopters throughout the war, from 1960, when the first US military advisers set foot in South Vietnam, under the Eisenhower Administration, to 1974, when the last US soldiers were withdrawn from Southeast Asia, under the Nixon Administration. Basically four types were employed in this war: cargo, transport, utility, and attack helicopter in support of ground troops. We can say the they constituted the bulk of the air supply line as well as the flying weapon of the US Army’s Infantry.

Bell UH-1 Huey. Not only was it the most massively used in Vietnam, but also came to symbolize the war.

For this last role, it was fitted with 70mm rockets and two machine guns. Maximum speed: 135 mph (217 km/h). Range: 315 miles.

Piasecki H-21 Shawnee. Making its first flight in 1952, it served in Vietnam since the beginning of the war and was the first aircraft specially designed as a troop transport helicopter, also being used in military supply missions.

Maximum speed: 127 mph (204 km/k). Range: 265 miles (427 km).
