Kochyerigin DI-6 was a two-seat fighter biplane produced in the Soviet Union in the 1930s. DI-6 was developed at TsKB as a fighter that would also be capable of ground attack when fitted with different armament. Originally intended to use a liquid-cooled V-12 engine problems with its development led to the choice of the Wright R-1820 radial engine instead.
