Comparing: IS-3 vs. Löwe

Mass production of the vehicle started in May 1945. On September 7,1945, IS-3 tanks took part in the Allied Victory Parade through Berlin. A total of 1170 vehicles were manufactured by the end of 1946, when production was canceled. From 1948 through the late 1950s, the tanks underwent a number of modernization refits.

Development of this 70-ton super-heavy tank started on November 1, 1941. In February 1942, the Krupp company suggested the VK 70.01 avant project, later designated the Löwe ("Lion"). Several designs varying in configuration, armament, and armor, were drafted. However, the project was canceled after the Führer made the decision to develop even heavier tanks. No prototypes were ever built.
