The Polikarpov R-5 was a massively-produced light bomber in service with the Soviet Air Force. It performed its first flight in 1928 and it was introduced into service in 1930. It was a sturdy reliable aircraft, which was the result of the communist government effort to catch up with Great Britain and the United States in aviation development. The State-run factory Polikarpov built a large number of the R-5, more than 6,000 units, in several versions. A torpedo bomber variant was also produced; the R-5T, in 1932.
It was used in combat for the first time in the Spanish Civil War (1936-1939) in support of the Spanish socialist government. During the first three years of World War II, it also saw combat action but in the reconnaissance role. It was also employed in the Far East against the Japanese forces, especially the ground-attack version, the R-5Sh, which was armed with seven machine guns and half a ton bombload. By mid 1944, it had been withdrawn from service.
