C-54 Skymaster

The Douglas C-54 Skymaster is a four-engined transport aircraft used by the United States Army Air Forces in World War II and the Korean War. Like the Douglas C-47 Skytrain derived from the DC-3, the C-54 Skymaster was derived from a civilian airliner, the Douglas DC-4. Besides transport of cargo, the C-54 also carried presidents, prime ministers, and military staff. Dozens of variants of the C-54 were employed in a wide variety of non-combat roles such as air-sea rescue, scientific and military research, and missile tracking and recovery. During the Berlin Airlift it hauled coal and food supplies to West Berlin.

Design C-54

With the looming entry of the United States into World War II, in June 1941[citation needed] the War Department took over the provision orders for the airlines for the Douglas DC-4 and allocated them to the United States Army Air Forces with the designation C-54 Skymaster. The first, a C-54, flew from Clover Field in Santa Monica, California on 14 February 1942.[1]

To meet military requirements the first civil production aircraft had four additional auxiliary fuel tanks in the main cabin which reduced the passenger seats to 26. The following batch of aircraft, designated C-54A, were built with a stronger floor and a cargo door with a hoist and winch.

Airforce One

President Harry S. Truman signed the National Security Act of 1947, which created the U.S. Air Force, on board Sacred Cow, the Presidential VC-54C which is preserved at the National Museum of the United States Air Force near Dayton, Ohio. More than 300 C-54s and R5Ds formed the backbone of the US contribution to the Berlin Airlift in 1948. They also served as the main airlift during the Korean War. After the Korean War, the C-54 was replaced by the Douglas C-124 Globemaster II, but continued to be used by the U.S. Air Force until 1972. The last active C-54 Skymaster in U.S. Navy service (C-54Q, BuNo 56501, of the Navy Test Pilot School, NAS Patuxent River) was retired on 2 April 1974.
