DH-4, de Havilland (Britain) / N.N.Polikarpov

36k b/w Russian-built DH-4 on skis "History of aircraft construction in the USSR" by V.B.Shavrov, Vol.1 p.333;

Very successful British light bomber/reconnaissater. DH-4 production in Russia on Dux factory was about to start in October 1917. Guess if it did or not?

During the Civil War manufacturing was frozen due to absence of the engines, but preparations did not stop. N.N.Polikarpov was steadily working on blueprints for assembly lines. In 1920 240hp 'Fiat', 260hp Mercedes and 220hp 'Siddeley-Puma' engines were acquired, what allowed to start production.

GAZ-1 (former Dux) manufactured 20 aircraft during 1920- 1921.

Acquired experience helped to start production of the R-1.
