I-190 N.N.Polikarpov

I-190 on skis

The last flown derivative of the I-153 biplane fighter. Powered with new compact M-88 engine aircraft included many improvements suggested during combat in Spain and Mongolia. As well as the predecessor, it was intended for highly maneuvrable dogfight in cooperation with high-speed fighters (I-16). It was a biplane fighter brought to its perfection. But it was already obsolete and unable to compete with monoplane fighters.
Spinner had 150mm central ventilation intake, with ventilation blades integrated into rear surface uf spinner.

The second I-190 (equipped with pressurised cocpit and turbocharcher for high altitude operations) was not finished.
