The Douglas C-133 Cargomaster was a large cargo aircraft built by the Douglas Aircraft Company between 1956 and 1961; 50 aircraft (35 C-133A and 15 C-133B) were constructed.

The C-133 had large tail doors and side doors and a large, open cargo area; large enough to transport ballistic missiles such as the Atlas cheaper and more quickly than road transport.

C-133s set a number of records, including records for military transport aircraft trans-atlantic in 1958 and lifting a payload of 117,900 pounds (53,479 kg) to an altitude of 10,000 feet (3,000 m).

With the introduction of the Lockheed C-5 Galaxy, the Cargomaster was obsolete, and all were withdrawn from service in 1971. One is preserved at the USAF Museum. There was also an example at the New England Air Museum . However, a tornado swept through the museum in 1979, virtually destroying the collection, including the C-133.
