Because of the birth of the Tiger tank, the Soviet Union urgently needed a heavy tank that could compete with it, whether in combat capability or in boosting morale. After the Battle of Kursk, the IS series heavy tanks finally stepped onto the stage of history. Today we will talk about the story of the IS (Stalin) series tanks during World War II.
IS-1 equipped with an 85mm main gun, only produced around 1943 107, IS-2 production was discontinued in October 1943.
The Soviet tank designers initially combined the KV-85 and KV-15 design schemes, so IS- The 85 (prototype designation) or IS-1 (production designation) was born. However, the military stated that the 85mm tank gun was crushed by the Tiger-style 88mm gun in all aspects. At least the soldiers felt that way, so they needed a A larger caliber gun.

A-19 122mm cannon
The designer originally chose between the A-19 122mm cannon (later D-25T) and the BS-3 100mm cannon (later D-10S used by SU-100). After some consideration, the 122 guns with stronger strike fortification capabilities were finally selected. Of course, this was related to the low production capacity of 100mm cannons at the time and the small stock of general-purpose shells.

This is an early IS-2 equipped with 122 guns. Pay attention to the first armor
The Stalin tank equipped with 122 mm is called IS-2, and the first armor has been fine-tuned, called the late IS -2 or IS-2 MOD 1Type 944.
This is the IS-2 that was later modified on the head. Its front armor is a large angle armor. The IS-2 of the C series also looks like this. Know someoneDid you notice it?
IS-2 played a very critical role in both actual combat effectiveness and morale boosting, because it is the first time ordinary soldiers seeAfter you have such a big guy on your side (the caliber of the main gun is bigger than the tiger), the tiger phobia will be much better.
About 3385 IS-2s were produced from 1943 to 1945. In addition to the two first versions during World War II, the Soviets also adjusted some key components of IS-2 after World War II. For example, the unreliable power unit, suspension system, and a number of improvements to the turret and ammunition racks, and new fire extinguishing devices have been installed on these tanks. Some of these post-war improved IS-2s were sold to China, and some were sold to North Korea, Cuba and other countries.
The magical revision of IS-2 This (obsolete), equipped with a 125mm main gun, 1967
IS-3, which is 1944 The heavy tanks that began to be developed in 1991 have been scientifically and rigorously developed. They are basically designed based on the valuable data left over from many tank battles between the Soviet Union and Germany. Therefore, their protective performance and firepower attributes have been developed. At the top of the contemporary era, we should also point out that the IS-3 plan puts too much emphasis on combat data and ignores some other details, such as the combat environment of the crew.

Because the test time is already October-November 1944, the Soviet counter-attack of the Germans’ ten strikes are coming to an end, Hitler’s lackeys have basically been scattered, the Soviet Union The main force is also in PolandThere are millions of soldiers on the border of Lanzhou. Therefore, the production of IS-3 is actually very hasty (for example, the welding process is not fine, the head of a tank was cracked by small-caliber artillery in the test, and the transmission system of IS-2 is easy to malfunction. ), because Stalin desperately needed this epoch-making heavy tank for a decisive battle, declaring that the German tanks were vulnerable and the Soviet tank was the world's first.
Introducing IS right after World War II -3’s literature
IS-3 only left the production line to equip troops in mid-May 1945. The European battlefield that did not participate in World War II is its biggest regret. However, it was on September 7, 1945. In the victory parade in Berlin, 52 brand-new IS-3s made the limelight. This new weapon with full crushing capabilities against German tanks and even the main tanks equipped by other countries in the world caused great panic in the Western world led by the United States. The Soviet Union is not only capable of overcoming Germany, but also capable of sweeping Europe!

In addition to failing to participate in World War II, IS-3 still has some combat records. However, as the IS-4 project entered the production stage, the production of IS-3 was also stopped. Many IS-3s were modified or sold by various demons, while the remaining IS-3sMuseums and monuments stored in some countries, such as the famous Ukrainian IS-3 in 2014, were opened by people to join the battle.
