Comparing: IS-3A vs. WZ-111

In 1956–1957, the Military Armored Forces Academy developed a speculative design for a new loading system on the IS-3 and T-10 heavy tanks. The IS-3 variant featured a double-row ammo rack with an automatic loading system. The crew was reduced to three members: commander, gunner, and driver. The turret was redesigned in order to accommodate the loading mechanism. The vehicle existed only in blueprints.

Development of the heavy tank prototype on the basis of the Soviet IS-2 and IS-3 began in the early 1960s under the influence of the T-10. The vehicle was supposed to modernize the armored forces of the PLA. The trials revealed multiple faults, and the development of the vehicle was discontinued in 1964.
