The IS-3 (also known as Object 703) is a Soviet heavy tank developed in late 1944. Its semi-hemispherical cast turret (resembling that of an upturned soup bowl) became the hallmark of post-war Soviet tanks. Its pike nose design would also be mirrored by other tanks of the IS tank family such as the IS-7 and T-10. Produced too late to see combat in World War II, the IS-3 participated in the Berlin Victory Parade of 1945, in the border conflict during the Sino-Soviet split, the Soviet invasion of Hungary, the Prague Spring, on both sides during the Six-Day War, and in very limited capacity during the Russo-Ukraine War.
