History
Designed by Polikarpov and first flown in 1926, the DI-1 was a biplane with an inline engine and tandem open cockpits. It was evaluated by the Soviet Air Force but not selected for mass production, as the design did not offer sufficient advantages over existing types.
Variants
The DI-1 remained a prototype; no production variants were ordered.
