VIT-2, N.N.Polikarpov


D
evelopment of the VIT-1 with new engines and yet more powerful armament. Twin tails provided better conditions for rear gunner;
First flown on May 11, 1938 by V.P.Chkalov, later by B.N.Kudrin (factory tests) and P.M.Stefanovskij (state acceptance tests). Performance was excellent. Decision was to launch series production with reduced armament, as a high speed dive bomber.
Developments:
  • SPB - high speed dive bomber;
  • There was a project for long range unarmed version (7900km at 350km/h or 6200km at 500km/h) with M-105 engines. Not built.
