Development

The I-17 was a lightweight single-seat low-wing cantilever monoplane. Developed under the design bureau designation TsKB-15 it first flew on 1 September 1934 powered by a 567 kW (760 hp) Hispano-Suiza 12 Ybrs engine. The second prototype designated the TsKB-19 had a revised inward retracting wide-track main landing gear and a Soviet M-100 engine. This second prototype was displayed at the 1936 Salon de l'Aeronautique in Paris. The third prototype designated the TsKB-33 had reduced armament to save weight and a revised engine cooling system, but the further development was abandoned in 1936.

A number of related unbuilt projects were also under development including the I-17Z parasite fighter under the designations TsKB-25 with a M-34RNF engine and the TsKB-43 with a Hispano-Suiza engine, none were built.

Notes
    gollark: It's certainly... very creative.
    gollark: Ah. So. If I understand this right, it goes through every authorized API key, tries to decrypt the message with the hash of that, and if one matches it takes that as the key to use for the connection?
    gollark: Of what?
    gollark: How exactly does it derive the encryption key to use?
    gollark: Why the `+''` anyway? That does nothing. Did it trigger a warning you wanted to ignore?
