The Polikarpov VIT-1 (Russian: Vozdooshny Istrebitel' Tahnkov— Flying Tank Destroyer) was a Soviet twin-engined multi-purpose aircraft developed before World War II.

The Polikarpov design bureau (OKB) was ordered, in 1936, to begin development of a fast twin-engined aircraft that could be used for ground attack duties and as a heavy fighter.

[2] The main legs of the conventional landing gear retracted aft into the engine nacelles, but the tailwheel was fixed.

The nose was extensively glazed to give the bombardier/navigator good visibility and he was armed with a 20 mm (0.79 in) ShVAK cannon with 10° of vertical travel.
