Douglas C-74

C-74 Globemaster I in Long Beach, California

the Douglas C-74 Globemaster was developed on request of the US Air Force after a transport aircraft with transatlantic range in the year 1942.


at the time of their first flight was the Globemaster with 78 tons maximum takeoff weight the heaviest land plane of the world. With their four Pratt & Whitney - Wasp major radial engines could transport it 125 fully equipped soldiers.

As special characteristic it received the same cockpit as the Douglas XB-40 with separate hoods for pilot and copilot, which was not particularly popular however at the crews. Therefore the cockpit was provided later with a conventional hood.

Also the machine in the course of the time received stronger engines.

There the first flight only to 5. September 1945 took place and the machine thereby for the employment in the Second World War came too late, production in January 1946 to only 14 machines was adjusted. Also planning for a civilian version was terminated.

While the citizen of Berlin air lift, which was supported by the Americans with C-74 , C-54 and C-47, they came to the realization that a heavy strategic transporter was needed. Thereupon a C-74 was converted to prototypes for the C-124 a Globemaster II, which possessed the same bearing areas and engines as the first Globemaster, but a substantially larger trunk.

This new model replaced the Globemaster I very fast and the last C-74 in the 1960ern and 1970ern was scrapped.
