The R-5 was developed by the design bureau led by Nikolai Nikolaevich Polikarpov as a replacement for the R-1(an unlicensed version of the DH.9A built in Russia) which served as the standard reconnaissance and light bomber aircraft with the Soviet Air Force.
The prototype first flew in autumn 1928,ered by an imported German BMW VI V-12 engine. It was an unequal-span single-bay biplane of mainly wooden construction.
After extensive evaluation, the R-5 entered production in 1930, powered by the Mikulin M-17, a licence-built copy of the BMW-VI, as a reconnaissance bomber. Further modified versions were produced to serve as floatplanes, ground-attack aircraft and civil transports.
The R-5SSS, an improved reconnaissance bomber with improved streamlining, served as the basis for the Polikarpov R-Z, which succeeded the R-5 in production.
The aircraft R-5 was designed by Nikolai Polikarpov in 1928. The aircraft was taken into the Soviet Air Force's use in 1931. They operated 5,000 aircraft R-5.[citation needed] Over 1,000 aircraft simplified for civilian needs were manufactured for Aeroflot under the designation P-5 (Russian: П-5).

Civil versions of the R-5 were used in large numbers, mainly by Aeroflot. They carried up to 400 kg (882 lb) of freight. Many were fitted with an enlarged rear cockpit to carry two passengers. Other aircraft were fitted with enclosed cabins for passengers. P-5s could also carry underwing containers (or Kasseta) for freight or passengers.
