The R-1820 Cyclone 9 represented a further development of the Wright P-2 engine dating back to 1925. Featuring a greater displacement and a host of improvements, the R-1820 entered production in 1931. The engine remained in production well into the 1950s.

The R-1820 was built under license by Lycoming, Pratt & Whitney Canada, and also, during World War II, by the Studebaker Corporation. The Soviet Union had purchased a license for the design, and the Shvetsov OKB was formed to produce the engine as the M-25. In Spain the R-1820 was license-built as the Hispano-Suiza 9V or Hispano-Wright 9V.

The R-1820 was at the heart of many famous aircraft including the early Douglas airliners (prototype DC-1, the DC-2, earliest civilian versions of the DC-3, and the limited-production DC-5), B-17 Flying Fortress, and SBD Dauntless bombers, the early versions of the Polikarpov I-16 fighter (as M-25), and the Piasecki H-21 helicopter. - Wikipedia
