High Quality Content by WIKIPEDIA articles! The Lockheed L-1249 Super Constellation was a turbine powered version of the Lockheed Constellation aircraft family. Built in 1954 and 1955 respectively, the aircraft were used as prototypes for possible future turbo-powered Military transport aircraft for both the United States Air Force and United States Navy. Both aircraft saw very short lives and the airframes were later used to build L-1049 Super Constellations.
