Description
Su-4
An upgraded version, originally intended for the Urmin M-90 engine with 1,565 kW (2,100 hp), but later fitted with a Shvetsov M-82. Due to a shortage of duralumin, the structural elements of the wings were made of wood with plywood skin. Wing armament was changed from four 7.62 mm ShKAS machine guns to two 12.7 mm Berezin UB machine guns. One prototype was built and tested, but this improved version was not placed into production
