ingle-seat low-wing monoplane fighter, prototype of the PI-1 and IP-1. The I-Z was designed to carry a single-shot recoilless gun under each wing. The front fuselage was that of the N.N.Polikarpov I-5 biplane fighter.
After two prototypes, 71 production aircraft followed; but because of handling problems, most were used in development roles.
