Fotogalleri på en IS-3 tung tank, som debuterade i slutet av andra världskriget den tunga tanken IS-3, som är en sovjetisk huvudstridsvagn, kunde inte ta en mycket aktiv roll i de sista striderna. Han deltog dock i militärparaden den 7 september 1945 i Berlin, främst i propagandasyfte. Beräkningen lönade sig eftersom den markerade tankarna hos observatörer av västmakter på grund av dess makt och modernitet. Namnet (IS eller JS) kommer från initialerna till Joseph Stalin då sovjetisk ledare ("J" för Joseph eller "I" för "Iossif" beroende på om den ryska versionen av namnet används eller inte), nummer 3 som anger numret på versionen i Josef Stalin-serien av tankar.

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.
