Only one MI-3 was built. During test flights problems with tailfins resulted in collapse of rudders upper parts. Pilot I.F.Kozlov managed to land the aircraft, cutting away landing gear. Repairs and redesign program began on March 1 1932.
Serious design revision produced the MI-3D (D stays for Dublior, the 'spare second one') with a single tailfin. Tail section was 'borrowed' as a whole from DIP-1, machineguns were replaced by 20mm 'Aerlikon'.
Aircraft is interesting as a transitional design. In the second prototype (MI-3D/ANT-21bis) open cockpits and turrets were replaced by enclosed. Corrugated skin was replaced by smooth one, general aerodynamics was improved.
