SU-76i - Tank Encyclopedia

The Red Army’s Panzer III 76mm SPGActive ServiceThe Su-76I Command Vehicle VersionThe GunGallerySurviving Su-76I SpgsThe SU-76i was built or re-built by the Soviets because, while speeding up their huge production of tanks, they still faced shortages in certain areas. Furthermore, the original SU-76 model had several flaws. They were unreliable and not a pleasure to drive, so much so the Soviet tankers named it “the Bitch”. During the fall of Stalingrad, the Soviets had captured several StuG and Panzer III tank chassis in relatively good condition. With the thought of rearming them with bigger Soviet guns, they were shipped back to factory 37 at Sverdlovsk. The SU-76i self-propelled gun was armed with a 76.2 mm (3 in) S-1 anti-tank gun By early 1943, the Soviets had some 300 StuGs and Panzer IIIs and decided to mount 76.2 mm (3 in) Zis-3sh guns into their hulls. The resulting non-turreted tank destroyer was meant to fill in the gaps where SU-76s had been destroyed or sent back for repairs. The initial design was to mount the 76.2 mm on a semi traversable pedestal similar to early Italian TD’s, but...Get price
