JS
Quick Summary
The JS, or Stalin, heavy tank was a Soviet tank that appeared in 1944 during World War II. It was armed with a 122-mm gun, though its muzzle velocity was lower than that of German 88-mm guns. The JS tank weighed 46 tons and primarily served to support medium tanks by destroying enemy tanks at long range.1
This heavy tank was part of a broader trend in tank development during the war, where nations focused on increasing firepower and armor. While the JS tank was a significant development for the Soviet Union, its role was specialized, and it was eventually superseded by tanks with more advanced capabilities in the post-war era.12
