The decision to spin up tank production at the Chelyabinsk Tank Factory (ChTZ) was made even before the war. The situation that developed in Chelyabinsk in the later half of the 1940s deserves a special mention. Their competitors from factory #100, headed by G.N.

It was necessary to increase the protection of the IS-2 so that the front of the hull and turret as well as the side of the turret and the turret platform were impenetrable to German shells. An analysis of tanks from early 1944 showed that Tigers could penetrate the cast front plate of early IS-2s from 1000-1200 meters and the Panthers could do it from 900-1000 meters. While the first IS-2 tanks were just driving out of the Kirov Factory in Chelyabinsk (ChKZ), the design bureaus of ChKZ and factory #100 already received order #5583 from the State Committee of Defense on April 8th, 1944: design a new heavy tank. Designers in Siberia, the Urals, and on the Volga overtook their colleagues in allied and enemy countries. Spun once, the flywheel of Soviet design bureaus built up an unseen inertia by the time the war was coming to an end. It took a fairly long time to build and 'tune' the tanks, and they arrived in the army only by the time that the Second World War was at an end. By January 25th, 1945, eight of the ten planned tanks had to be built. The order to produce a new tank under the index IS-3 was received by Chelyabinsk factory management on December 16th, 1944.
