It was powered by the Pratt & Whitney R-2800 engine, producing 2,000 horsepower. Ironically, this was the engine originally intended for the airplane. Other changes included: replacement of the Hamilton-Standard propellers with four blade Curtiss Electrics, no cabin pressurization (although the airplane retained its service ceiling of 22,000 feet – no doubt due to the two stage supercharger equipped engines – a vestige of the airplane’s pressurized airliner roots), a reinforced cargo floor, and extra large cargo doors on the fuselage. Although 17 different variants of the airplane were produced, the C-46A and C-46F made up the bulk of the production run. A total of 3140 Commandos were made before production ended in 1946.
