The Wright R-1820 Cyclone 9 was an American nine-cylinder, single-row, air-cooled radial engine developed by Curtiss-Wright and widely used in aircraft from the 1930s to the 1950s. A development of the Wright P-2 of 1925, it entered production in 1931 with a displacement of 1,823 cubic inches (29.9 litres) and stayed in production into the 1950s. It powered the prototype Douglas DC-1, the DC-2 and early DC-3 airliners and every wartime Boeing B-17 Flying Fortress, and the R-1820-97 was the most built variant, at 64,093 engines. Lycoming, Pratt and Whitney Canada and Studebaker built it under licence, and it was made in Spain as the Hispano-Suiza 9V and in the Soviet Union as the Shvetsov M-25. Caterpillar adapted it as the D-200 multi-fuel diesel for the M4A6 Sherman tank.
