Overview[]

The IS-4 is a Soviet heavy tank developed in the mid 1940s.

Development[]

Development of the IS-4 began in the final weeks of 1943. N.L. Dukhov lead the design team and a number of prototypes were constructed and tested until a final model was accepted as Ob"yekt 701 in 1946, and manufactured by ChKZ in 1947.

Production was planned to run from 1947 to 1952 at ChKZ, but in 1951 the modernized IS-4M took over production. 219 IS-4 were manufactured during this time, with 217 of them returning to the factory to be upgraded to IS-4M standard.
