| The TsKB-15 single-seat fighter prototype was a diminutive low-wing monoplane of slim configuration, powered by an imported 626kW Hispano-Suiza 12Y inline engine. With an inward-retracting undercarriage, it flew in September 1934 and was followed by the TsKB-19 with the M-100 (Soviet version of the Hispano engine). Armament comprised a 20mm cannon and four 7.62mm machine-guns. Production of a small number as the I-17-2 was reported, but it is not known if the type was used by first-line units. A third prototype (the TsKB-33) had reduced armament in an attempt to cut down weight and increase performance. The projected use of this version as a parasite fighter to be launched from a multiengined 'mother ship' was subsequently abandoned.

However, the Soviet Government chose not to develop this fighter further and to persist with production of the I-16. As a result, the Red Air Force did not get a fighter with a modern liquid-cooled engine, comparable to foreign counterparts, until 1941. Nevertheless, the I-17 prototype was displayed prominently at the Paris Aeronautical Salon in 1936, where foreign aeronautical experts apparently were more impressed with it than the Soviets were. reply | | sven, 09.09.2016 19:01 The huge fillet on the fuselage wing joint is likely to have caused unpleasant handling and contrary to appearances a lot of drag. reply | | CRoW56, e-mail, 09.09.2014 23:44 This aircraft has sweet lines and looks like it would be fast and handle well. Why was it abandoned? reply |
