The JS-2 Heavy Tank, which was also known as the Victory Tank, was an upgraded version of the JS-1, with a larger main gun.
Production of the JS-2 began at the end of December 1943. By the beginning of 1944, about 100 JS-2s were in service.
A 4.8 inch (122mm) main gun was fitted onto the JS-2, which had more powerful weaponry than any other tank when it first appeared.
The JS-2 also had a smaller cupola than the JS-1 and its armor silhouette around the hull was different from that of the JS-1.
After the Soviets produced the JS-2, they went on to produce an even more advanced version of the JS series, the JS-3.
