Comparing: WZ-111 model 1-4 vs. IS-7 vs. 113

Prototype of a heavy tank developed in the early 1960s. The 111 project was developed on the basis of the Soviet IS-3 and T-10 tanks. In 1964 development was discontinued in favor of new types of medium tanks.

Development of the IS-7 started in the spring of 1945. Prototypes successfully underwent trials in 1946 and 1947. However, the IS-7 never saw mass production.

Development on model 113 was started in 1963. The vehicle was conceived as an alternative to WZ-111 and used parts and components of medium tanks. However, the project was canceled due to the development of main battle tanks.
