IS-4
Sign in to saveThe IS-4, also known as the Object 701, was a Soviet heavy tank that started development in 1943 and began production in 1946. Derived from the IS-2 and part of the IS tank family, the IS-4 featured a longer hull and increased armor. With the IS-3 already in production, as well as the decreased need for tanks (particularly heavy tanks) and sluggish mobility, many were sent to the Russian Far East with some eventually becoming pillboxes along the Chinese border in the 1960s. Fewer than 250 were produced.

The IS-4, also known as the Object 701, was a Soviet heavy tank that started development in 1943 and began production in 1946. Derived from the IS-2 and part of the IS tank family, the IS-4 featured a longer hull and increased armor. With the IS-3 already in production, as well as the decreased need for tanks (particularly heavy tanks) and sluggish mobility, many were sent to the Russian Far East with some eventually becoming pillboxes along the Chinese border in the 1960s. Fewer than 250 were produced.
==Design and production== Development of the IS-4 started in November 1943 with the purpose of improving upon the IS-2 and incorporating captured enemy technology. This created a blend of IS-2 features and unique features not found in other Soviet tanks. The first variant IS-2 stepped front plate was judged to be a weak point and made into a single glacis with additional armor for the driver. This was in order to accomplish the IS-4 design parameters which included protection from the German 8.8 cm Pak 43 anti-tank gun. The side hull of the IS-4 is a simple angular step instead of angling out like the IS-3. The right side of the tank was fitted with clamp rings to carry an unditching log. The driver's position was described as cramped, though the writer of the review was taller than what was typical for tankers of the time.
