Development of the DH-4 British light bomber/reconnaissater. N.N.Polikarpov was steadily working on blueprints for DH-4 assembly lines. During the Civil War some latest DH-9 and DH-9a were captured, and modifications were included into the project. After the War engines were acquired and in 1922 few dozens DH-9 airframes were purchased in Great Britain.
In 1921 one of captured DH-9 was equipped with radiostation, and on September 28 (or 30?) first successful communication between pilot and ground station was established during trials at Moscow experimental airfield.
Aircraft was designated R-1 and was powered with 260hp Mercedes engine. Differed from Russian-built DH-4 by the engine and location of cockpits.
About 100 were built in 1922- 1923.
Gained experience helped to start production of the 'all-Russian' R-1.
