76 Mm Anti-tank Gun Zis-s-58-1 Details

The widespread use of the Wehrmacht in 1943 by the Germans on the Eastern Front of the new powerful heavy tanks Pz.Kpfw.VI Ausf.E “Tiger”, Pz.Kpfw.V “Panther”, modernized medium tanks Pz. Kpfw. IV models H, M and N and self-propelled artillery installations “Ferdinand”, which had armor thickness of 80-100 mm, required the Soviet military command to take urgent retaliatory measures at the most crucial moment of the Great Patriotic War. The Red Army needed a new effective means of destruction of heavy-duty German tanks. GKO decree No. 3187 of April 15, 1943 demanded to strengthen the anti-tank defense of the Red Army. The Soviet defense industry needed to create an anti-tank gun capable of penetrating the armor of promising German tanks.

Almost all Soviet artillery design bureaus began to develop and manufacture prototypes, including the Central Artillery Design Bureau (TsAKB) in Kaliningrad near Moscow under the leadership of V.G. Grabin. In 1944, a new model of the 76-mm divisional gun ZIS-S-58-1 was created at TsAKB.

Back in 1940, the Grabin Design Bureau began designing a 76-mm ZIS-13 high-power divisional gun for a unitary shot from a 76-mm anti-aircraft gun mod. 1931 g. The barrel length of the ZIS-13 was 54.8 caliber, the weight of the high-explosive fragmentation projectile was 6.61 kg, and the muzzle velocity was 813 m / s. The carriage was borrowed from the 76-mm USV divisional gun with reinforced recoil devices.

The prototype of the ZIS-13 cannon was manufactured at Plant No. 92. Factory tests were carried out from September 9, 1940 to February 19, 1941. At the end of February 1941, the gun was sent for field tests. Further work on it was discontinued in connection with the creation of the 76-mm ZIS-3 cannon. These works served as the basis for the creation of a new divisional guns.

The ZIS-S-58-1 cannon had a light two-wheeled carriage with sliding box-type beds and torsion cushioning (structurally similar to the carriage for the 85-mm ZIS-S-8 divisional cannon), on which a monoblock barrel was mounted with a semiautomatic vertical breechblock of the copy type. A screw-on breech and a high-power muzzle brake were mounted on the barrel. Rollback brake – hydraulic, reel – hydropneumatic, balancing mechanism – pneumatic, lifting mechanism – sector type.

The wheels were borrowed from the ZIS-5 car. The gun had a projectile mass of 6 kg. Its initial speed was 680 m / s. The prototype of the ZIS-S-58-1 cannon was manufactured by Plant No. 92 in the same 1944, passed factory and field tests, but was not adopted for service. Strengthening the armor protection of German tanks, as well as the creation of more powerful divisional and field guns of caliber 85-100 mm, deprived such 76-mm guns of further prospects.
