The Lockheed L-1049 Super Constellation is designed and produced by Lockheed Corporation from 1951 to 1958. It was developed from L-049 and first flew on July 14, 1941. A total of 259 commercial and 320 military L-1049 were built. The L-1049 was retired from commercial service and preserved examples exist as private aircraft.
During early 1943, the aerospace company Lockheed Corporation began to develop stretched versions of the Constellation series. The first stretched version was the L-049 followed by the L-749. After the Douglas Company introduced the DC-6 rival aircraft, Lockheed developed the L-1049 as a response.
On July 14, 1951, the initial production version L-1049 took its first flight. In November of the same year, the aircraft was awarded its type certification. In December 1951, it entered service with Eastern Airlines. In 1952, Trans World Airlines started to operate the aircraft, and beginning in 1955, L-1049Gs started in service flying transatlantic routes.
The L-1049C is a civilian variant of the L-1049B and forty-eight of these were built. The L-1049G is a development of L-1049C equipped with an increased maximum takeoff weight and four R-3350 -3 engines.
The L-1049C version can accommodate forty-seven to one hundred and six passengers. It has five crew members including a pilot, copilot, navigator, engineer, and radio operator. The aircraft has an exterior length of 34.62 meters, an exterior height of 5.7 meters, and a fuselage width of 3.7 meters. It has a tail height of 7.54 meters.
