The Wright R-1820 Cyclone 9 is an American radial engine developed by Curtiss-Wright, widely used on aircraft in the 1930s through 1950s. It was produced under license in France as the Hispano-Suiza 9V or Hispano-Wright 9V , and in the Soviet Union as the Shvetsov M-25 .
The new Wright R-1820 Cyclone 9 first ran in 1935, and became one of the most used aircraft engines in the late 1930s and early 1940's, powering the Boeing B-17 Flying Fortress heavy bomber, General Motors FM-2 Wildcat fighter and Douglas SBD Dauntless dive bomber, among many others.

The B-17's turbocharged Wright R-1820 Cyclone 9 engines were upgraded to increasingly more powerful versions of the same powerplants throughout its production, and similarly, the number of machine gun emplacement locations was increased. [68] Boeing-built B-17Fs, with the clear-view two-piece Plexiglas bombardier's nose.
For example: the -18W was a "C" series engine, built from 1945, whereas the -21 was a "B" series engine, built from 1943. Until 1940 the armed forces adhered strictly to the convention that engines built for the Army Air Forces used engine model numbers with odd numeric suffixes (e.g.: -5), while those built for the US Navy used even (e.g.: -8).
The B-17B (299M) was the first production model of the B-17 and was essentially a B-17A with a slightly larger rudder, larger flaps, a redesigned nose and 1,200 hp (890 kW) R-1820-51 engines. The small, globe-like, machine gun turret used in the Y1B-17's upper nose blister was replaced with a .30 in (7.62 mm) machine gun, its barrel run through ...

In 1935, Curtiss-Wright began work on a more powerful version of their successful R-1820 Cyclone 9. The result was the R-2600 Twin Cyclone, with 14 cylinders arranged in two rows. The 1,600 hp (1,200 kW; 1,600 PS) R-2600-3 was originally intended for the C-46 Commando (being fitted to the prototype CW-20A).
