Soviet armoured fighting vehicle production during World War II from the start of the German invasion of the Soviet Union on 22 June 1941 was large. Although the Soviet Union had a large force of combat vehicles before the German invasion, heavy losses led to a high demand for new vehicles. Production was complicated by the loss of production facilities in the western part of the Soviet Union, and entire factories were moved east of the Ural Mountains to put them out of reach of the Germans. In general, Soviet tanks had less interior space than the tanks of other nations (which made them smaller targets) – this was possible because the Red Army only employed soldiers of small stature in their tank forces. Combat experience in the Spanish Civil War (1936–1939), the Battles of Khalkhin Gol (1939) and the Winter War (1939–1940) showed the Soviet military that light tanks (such as the T 26) were too lightly armoured and that multi turreted tanks (such as the T 35) were inferior to single turret tanks which guided the switch to the later vital T 34 medium and KV 1 heavy tanks. Figures are up until the first half of 1945 and only include new production. The Soviet Union had 25,664 or 25,481 armoured fighting vehicles on 1 June 1941 before it entered the war. Not shown here are armoured cars, aerosans, artillery tractors and armoured trains.

The KV 1 (named after Kliment Voroshilov) was armed with a 76 mm gun; as with the T 34, the length of the gun was increased during production. The KV 1S was a version of the KV 1 with lighter armour (making it faster) and a new turret (still with a 76 mm gun). KV 85 was a KV 1S fitted with an 85 mm gun in the same turret as the IS 1. After Voroshilov lost political favour, the new KV 13 model with the KV 85's turret and gun was renamed IS 1 after Joseph (Iosif) Stalin. It was soon upgraded to a new turret with high velocity 122 mm gun, and renamed IS 2, finally giving a slow, expensive heavy tank one clear superiority over the medium T 34. The IS 3 was an IS 2 with new, advanced hull and turret armour. It saw no combat in World War II. The KV 8 was a flamethrower tank.

The KV 2 used the same hull as the KV 1 but was armed with a 152 mm howitzer in a huge turret which could not even rotate on uneven terrain and was intended for use against fortified targets and infantry. The SU 152 was a 152 mm howitzer, casemate housed on a KV 1S hull. Like the KV 2 it was intended for use as an assault weapon against infantry, but used the cheaper and less exposed Samokhodnaya Ustanovka designated style of casemate mount. The ISU 122 and ISU 152 were self propelled guns on casemate fitted IS hulls. They were both used as heavy assault guns; and both were useful as Anti Tank weapons. The 122s D25 Gun could penetrate almost any German tank, and the 152s ML20 had long been used against enemy armour; although it had a low velocity, the massive shell could inflict considerable damage through concussive effects.
