C-133A-5-DL

 

Resulting from studies aimed towards a successor to the Globemaster II, the C-133 Cargomaster was worked up by Douglas’ designers beginning in February 1953, and the first aircraft was rolled out on 27 March 1956.


A huge airlifter with high-mounted wings powered by four 5,700-shp Pratt & Whitney T34-P-3 turboprop engines, the C-133 had its cargo-loading door in the rear fuselage. It was designed to carry heavier and bigger loads than the Lockheed C-130 Hercules, although its internal capacity did not represent a significant increase over the C-124 Globemaster II. First flown on 23 April 1956 and delivered to MATS on 1 August 1957, 35 C-l33As were followed by 15 C-l33Bs powered by 7,500 hp / 5,589kW T34-P-9W turboprops, the latter with an improved cargo door and increased payload. Some Cargomasters were used to transport the first generation of intercontinental ballistic missiles (ICBMs) and intermediate-range missiles such as Atlas, Thor and Redstone. Production ended in April 1961.
