The Lockheed L-1249 Super Constellation was a turboprop-powered version of the Lockheed Constellation family. Two aircraft were built in 1954 and 1955 as prototypes for possible future military transports for the United States Air Force and the United States Navy, and both had very short lives before their airframes were used to build L-1049 Super Constellations. It began when the Navy signed a contract in August 1950 for eleven military transport versions of the L-1049, and in 1951 the idea came up of a turbine-powered version of the R7O-1. In 1954 two R7V-1 airframes were pulled off the line and fitted with four Pratt and Whitney YT34-P-12A turboprop engines of 5,500 brake horsepower each in place of the usual Wright R-3350 radials. Designated R7V-2, the first flew on 1 September 1954 and both were delivered to the Navy on 10 September.
