Tthe IS-4, 또한 개체 701, 1943 년에 개발을 시작하고 1946 년에 생산을 시작한 소비에트 중전차였습니다. IS-2와 IS 전차 제품군의 일부에서 파생된 IS-4는 더 긴 선체와 증가된 갑옷을 특징으로 합니다. IS-3가 이미 생산 중이며 탱크 (특히 중전차)에 대한 필요성이 감소하고 이동성이 느려지면서 많은 사람들이 러시아 극동으로 보내졌으며 일부는 결국 1960 년대에 중국 국경을 따라 알약 상자가되었습니다. 250개 미만이 생산되었다.

The “Object 701” Evolution
Tthe IS-4 (JS-4) was developed at the end of WWII as a successor to the IS-2 and a more reliable alternative to the radical IS-3. While the IS-3 used the famous “Pike Nose” to save weight, the IS-4 went in the opposite direction: pure mass. It was built with incredibly thick, traditional sloped armor, making it practically invulnerable to most anti-tank guns of the late 1940s. However, this came at a cost of 60 tons, making it too heavy for many Soviet bridges and rail lines.

Armor and Reliability
- Side Armor Dominance: One of the IS-4’s most unique traits was its 160mm side armor. This was thicker than the frontal armor of most contemporary tanks, allowing it to “side-scrape” and absorb hits that would destroy any other vehicle.
- Advanced Transmission: Unlike the crude gearboxes of earlier Soviet tanks, the IS-4 featured a sophisticated planetary transmission with a steering mechanism that allowed for much easier driving, though it was complex to maintain.
- Rear Radiator Design: The engine cooling system was inspired by German designs (specifically the Panther), utilizing two large fans at the rear to draw air through radiators, which was more efficient than previous Soviet layouts.
- The D-25T Gun: While powerful, the 122mm gun used two-piece ammunition (projectile and powder charge), which resulted in a slow rate of fire (approx. 2-3 rounds per minute).
Operational History: The Far East Shield
- Production Numbers: Only about 250 units were built between 1946 and 1949. The Soviet high command eventually realized that the tank was simply too heavy for the logistics of a fast-moving European war.
- Exile to the East: Due to its weight and logistical requirements, most IS-4s were stationed in the Soviet Far East (near the borders of China and North Korea). They were seen as mobile pillboxes that could hold strategic positions against any invasion.
- Target Practice: By the 1960s, the IS-4 was considered obsolete compared to the T-54/55 and the upcoming T-62. Many were used as static fortifications or hard targets on gunnery ranges.
