Douglas C-132

The Douglas C-132 was an American military transport aircraft proposed in the 1950s by the Douglas Aircraft Company, based on the company C-124 Globemaster II, and it would have been the largest aircraft of its era. In January 1951 the Air Force asked for a preliminary design of a heavy cargo transport able to carry 100,000 pounds of payload 4,000 miles, and by December 1952 it selected the Douglas proposal, which would serve as a cargo transport and an air-to-air refueling tanker. Douglas announced that it would use the Pratt and Whitney T57 turboprop, and a mockup was built in February 1954. First flight was planned for April 1957, then slipped to mid-1959, but the project was officially cancelled on March 20, 1957, before a first flight.
