Soviet tanks were attacked by improvised weapons. The hull of an IS-3 that was destroyed during the 1956 Hungarian Revolution in Budapest. The first public demonstration of the IS-3 came on the 7th of September 1945, at the Allied victory parade in Berlin.Īs it rolled down the Charlottenburger Chaussee in Berlin, its appearance caused major alarm for the West as the tank was much better protected and armed than any tanks in Western arsenals at that time. Regardless, it would become very involved in conflicts immediately following the war. There is also other unverified reporting that IS-3s saw limited action against Japan during the very last days of the war. ServiceĪs previously mentioned, the IS-3 was introduced too late to see action in WWII, although there is some debate on this as there are unconfirmed reports of pre-series models being involved in combat after the German surrender. The IS-3’s general layout and design would evolve, resulting in future vehicles such as the IS-7 and T-10. The IS-4 had simpler, but much, much thicker armor. Therefore, the IS-3 possessed reduced capability to adopt hull-down positions.īecause of these teething troubles, another Soviet heavy tank, the IS-4, entered service as a precaution. This style of turret improved protection but it also significantly reduced crew space, limitedġ22 mm ammunition capacity to 28 rounds and restricted the main gun’s maximumĭepression as the gun breech had restricted room inside the turret to elevate. This shape, which is often described as an upturned soup bowl, would become a standard feature on Soviet tanks from that point on.Īnother Article From Us: IS-4 – The Forgotten Soviet Heavy Tank One of the IS-3’s most distinguishing features was its semi-hemispherical cast turret. The IS-3’s armor was highly complex for the time, incorporating many angles that greatly improved effective thickness and the chances of ricochets. Many other features were radically different. The IS-3’s Unique DesignĮven though the main armament and engine of the IS-3 remained unchanged from the IS-2, The two different most clearly in their armor layout.Īs development for the IS-3 did not occur until late 1944, and it was a major departure from the IS-2, the tank did not come off the production line until May 1945 although some pre-series vehicles were issued to the Red Army that spring. The IS-2 was similar to the IS-3 in many ways. As a result, it was an almost complete redesign from its predecessor. Development of the IS-3 took into account lessons that had been learned from the design and combat experience of the IS-2. 100 Kirovskiy Works as an improvement on the IS-2. The development of the IS-3 (originally known as Object 703) started in late 1944 at the Factory No. This has resulted in controversy amongst some who suggest that the IS-3 was overrated, and others that claim the tank’s poor record was due to poor training and tactics. However it would come to earn a rather poor combat record, becoming something of a “paper tiger”. The IS-3 caused significant alarm in the West when introduced due to its powerful armament and advanced protection, which combined raw thickness with complex angles. Although the IS-3 arrived too late to see combat in WWII, it would become the main Soviet tank of the immediate Cold War period and participate in conflicts throughout the 1950s and ’60s and even into the modern day. The IS-3 heavy tank was a late World War Two Soviet tank design that was an
