The Wright R-975 Whirlwind was a series of nine-cylinder air-cooled radial aircraft engines built by the Wright Aeronautical division of Curtiss-Wright, displacing about 975 cubic inches (15.98 litres) and rated from 300 to 550 horsepower depending on variant. It was the largest and most numerous commercially produced member of the Whirlwind family, originating as the J-6 Whirlwind Nine of 1928, with a larger bore than the R-790 and a gear-driven supercharger. It powered civil aircraft such as the Beechcraft Staggerwing and the Lockheed 10B Electra, and trainers such as the North American BT-9. Wright built over 7,000 before production ended in 1945, but Continental Motors, building the engine under licence, made over 53,000 for American and Allied tanks including the M3 Lee, the M4 Sherman and the M18 Hellcat.
