June 22, 1941 the gates of the plant was released experienced benchmark the most famous gun majestically Russian War, made famous Russian designer VG Grabina, ZIS-3. A month later successfully passed factory tests are standard ZIS-3 was presented to Marshal Kulik.
In developing the guns were taken into account all the features of the latest statement of guns in series creation. Statement of the ZIS-3 has permitted the creation of a gross plant output increment divisional guns, instead of the 2-ZIS-2 and F-22 USV can produce only one ZIS-3 creation which will manage the plant is three times cheaper, besides newcomer gun reliable and easy to maintain. All these reasons creator gun Grabin led Kulik, but still received a categorical "no" marshal.
"You want to plant an easy life, while at the front there is blood. Your guns are not needed. Go back to the plant and make more guns that are in production. "
But Grabin not even his own fellow such an ignominious fate went on a risky move, and despite the angry response Kulik launched ZIS-3 in a semi-underground, batch creation.
The assembly shop collected ZIS-2 without installing them on the pipe stem. The only significantly different in detail muzzle brake, to conspiracy manufactured in experimental shop. At night general assembly was carried out in the morning and ready acceptance of military guns were presented.
Officially, the ZIS-3 was adopted by 12 February 1942. By the time the front which made war about a thousand ZIS-3. In all there were a record number of copies of the ZIS-3 48 016 units, more than any other gun ever in the history of mankind.
But the Germans did not have an analogue ZIS-3, because they used the French invented the doctrine of "trinity" aimed at short-lived mobile warfare, divisional guns at them was not perfect.
Shooting from the ZIS-3 were decided following tasks: the destruction of the bunker (long gun emplacements) and entanglements of the enemy, destruction of manpower, artillery, tanks and other mechanized means the enemy. When shooting ZIS-3 you can use different types of shells: cumulative, high-explosive grenades, sabot, armor-piercing, smoke, shrapnel, incendiary, which allows for a huge bounce-fire. Range of fire high-explosive fragmentation grenade was equal to 13,290 m range direct fire grenades and armor-piercing projectile was 820 meters. When you break the RP-350 was produced for slaughter 870 fragments with a range of 15 meters on the distance of 500 m at an angle of 90 ° of the meeting piercing projectiles penetrated the 70-mm armor.
ZIS-3 successfully fought against all German medium and light tanks and self-propelled guns. Also ZIS-3 simply ruled with "Panthers" from a distance of 300 meters it could even cope with "Tiger".
ZIS-3 gun which adored gunners completed its task and to brought it significant contribution to the stateliness of victory, bringing well-deserved reputation own creator, a professional designer Basil Gavrilovichu Grabin.
