The Polikarpov I-180 (Russian: И-180) was a 1938 Soviet fighter prototype. It was the last attempt to extract performance from the basic Polikarpov I-16 design.[1] The development cycle was plagued with problems,[2][3] especially with the death of the star Soviet test pilot Valery Chkalov in one of the prototypes.
