I-16P, N.N.Polikarpov

The first attempt to install rapid-fire 20mm cannon on the Soviet fighter. 'P' stays for 'Pushechnyj', the cannon armed one.

It was a version of the I-16 Type 5 with imported 1*710hp Wright-Cyclone F-3 engine. Two ShVAK 20mm synchronized cannons (150 rounds/cannon) were installed in wings close to the fuselage. Also carried six Der-31 bomb containers under the wings.

According to V.B.Shavrov, pair of synchronized ShKAS machineguns were installed on the I-16P on the top of fuselage and fired through the propeller. Photo of cannon-armed I-16P at 'Polikarpov Fighters in action, Part 2' clearly shows the ShKAS on the same place as on 'normal' Type 5. So comes a puzzle.

Two built, on with fixed and another with retractable landing gear. Flying characteristics where about the same as series production I-16 I-16 Type 5. Despite results of flight tests and firing trials were successful, it took two more years to put cannon armed fighter into series production as I-16 Type 17.
