The Allison T40, company Model 500, was an early American turboprop made of two Allison T38 power sections driving contra-rotating propellers through a common gearbox. The US Navy contracted for a 4,100 shaft horsepower engine and testing began in 1948. It flew first in the Convair XP5Y flying boat in 1950 and powered the Convair R3Y Tradewind, the only aircraft to use it in real service, as well as the Convair XFY Pogo and Lockheed XFV vertical takeoff fighters. The engine was never reliable: gearbox failures, propeller control problems and a clutch system that could not cope with a failed section ended most programmes, including the Douglas A2D Skyshark and the Republic XF-84H.
