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

Object 703 was developed in late 1944 by Factory No.100 Kirovskiy Works or ChTZ (in Chelyabinsk) and left the factory workshop in May 1945. This tank had an improved armor layout and a hemispherical turret (similar to that of an overturned bowl of soup), which became the hallmark of post-war Soviet tanks. While this low, hemispherical turret improved protection, it also significantly reduced crew headroom, particularly for the loader. The low turret also limited the maximum depression of the main gun, as the gun breech had little room within the turret to rise, and this limited the extent to which the IS-3 could take advantage of hull-down positions. The IS-3’s pointed bow, the so-called pike nose, earned it the nickname Shchuka (Pike) from its crews. It weighed slightly less and was 28 centimeters (11 in) lower than previous versions. Wartime production caused many mechanical problems and a hull weld line that was prone to cracking. The IS-3M solved some of these problems.

The IS-3 arrived too late to see action in World War II. The first public demonstration of the IS-3 occurred on 7 September 1945 during the Allied victory parade on Charlottenburger Straße in Berlin, with the heavily reinforced 71st Heavy Tank Regiment of the 2nd Guards Tank Army. Starting in 1960, the IS-3 was slightly modernized as the IS-3M, similar to the IS-2M.

The IS-3 was a significant improvement over the IS-1 and IS-2 due to its spade frontal armor. Having already pre-angled frontal hull armor meant that less armor was needed to maintain the same effective armor thickness on the upper glacis.
