Polikarpov I-3

Trouble with the I-1 monoplane led Polikarpov to design a new fighter as a biplane, and in 1927 the I-3 appeared. Powered by a 447kW M-17 engine, it entered production and service, later being supplemented but not replaced on production lines by the superior I-5. Several hundred I-3s were built.
