Galeria de fotos em um tanque pesado IS-3, Fazendo sua estréia no final da Segunda Guerra Mundial, o tanque pesado IS-3, que é um tanque de batalha soviético, não pôde participar muito ativamente dos últimos combates. No entanto, ele participou do desfile militar em 7 de setembro de 1945 em Berlim, principalmente para fins de propaganda. Um cálculo que valeu a pena, pois marcou a mente dos observadores das potências ocidentais por causa de seu poder e modernidade. O nome (IS ou JS) vem das iniciais de Joseph Stalin, então líder soviético ("J" para Joseph ou "I" para "Iossif", dependendo se a versão russa do primeiro nome é usada ou não), o número 3 designando o número da versão na série de tanques Josef Stalin.

The IS-3 (or Object 703) was a heavy tank developed by the Soviet Union in the final stages of World War II. While it did not see combat during the war, it was a revolutionary design, notable for its sloped frontal hull, known as the “pike nose,” and its distinctive semi-hemispherical cast turret. The tank’s appearance at the 1945 Berlin Victory Parade greatly alarmed Western Allies, influencing post-war tank development in NATO nations.
Design and Development
Innovative Armor Layout
- Initial Requirement: To create a heavy tank with superior protection against German 88 mm guns, addressing the frontal weaknesses of its predecessor, the IS-2.
- Pike Nose: The frontal hull consisted of two heavily sloped armor plates welded together at a sharp central angle. This configuration maximized the effective thickness of the armor and increased the chance of ricochet.
- “Soup Bowl” Turret: The low-profile, cast, dome-shaped turret was inherently stronger ballistically than previous designs, offering excellent all-around protection due to its curvature and minimal vertical surfaces.
Service and Flaws
- WWII Service: Though production started in May 1945, the tank was too late for combat against Nazi Germany. It did, however, participate in the Berlin Victory Parade in September 1945.
- Mechanical Issues: Early production models suffered from significant reliability problems, including weak engine components, gearbox failures, and hull welds that cracked under stress from driving.
- Combat History: The IS-3 saw limited action with the Soviet Army during the 1956 Hungarian Revolution and was later exported, most notably to Egypt, where it saw service against Israel during the Six-Day War in 1967.
