Photo gallery on a heavy tank IS-3, The heavy tank IS-3 is a Soviet battle tank that appeared at the end of world war without having had time to take an active part in combat. He was first seen at the military parade on September 7, 1945, during which he impressed Western powers with his modernity. Its name comes from the initials of the Soviet dictator Joseph Stalin ("I" for "Iossif") and the number 3 is due to the fact that it was the third version of the Josef Stalin tank series to be designed and commissioned.

While designed in late 1944, it arrived too late to see significant combat in World War II, with the first production batch leaving the factory in May 1945. It is, however, considered a transitional design and one of the first post-war Soviet tanks due to its revolutionary armor layout. Its distinctive profile earned it the nickname “Shchuka” (Pike) by its crew.

Key Design Features
- “Pike Nose” Hull: The most defining feature of the IS-3. The frontal armor was composed of three welded plates angled steeply into a ‘V’ shape, which maximized the chance of shell deflection and increased effective armor thickness (up to 110 mm at 55° on the glacis).
- Hemispherical Turret: The turret was a low, flattened, cast dome (up to 250 mm thick on the front). This shape drastically increased its ballistic protection and became the hallmark of subsequent Soviet tank designs, including the T-54/55.
- Powerful Main Gun: It retained the high-velocity 122 mm D-25T gun from the IS-2, known for its incredible destructive power against armor and soft targets. However, the use of two-piece ammunition (separate shell and charge) resulted in a slow rate of fire (2–3 rounds per minute) and necessitated a dedicated loader.
Service and Legacy
Although it missed the war, the IS-3 had a significant impact on post-war tank design, both Soviet and Western, due to its advanced armor geometry. It was prominently displayed during the 1945 Allied Victory Parade in Berlin, which reportedly caused significant concern among Western military observers. The tank later saw action in conflicts like the Soviet invasion of Hungary (1956) and the Six-Day War (1967).
