Super-heavy tanks are armored vehicles of very large size, generally over 75 tonnes. They have been introduced on several occasions in order to provide an invincible vehicle for penetrating enemy formations without fear of being destroyed in combat. Examples date to World War One and World War Two, along with a few Cold War examples. Only a few examples were ever built, and with one exception none of these vehicles saw combat.
The earliest examples of super-heavy designs date to WWI, when the British worked on their Flying Elephant concept as a way to break through any potential defensive line. During WWII all of the major combatants introduced prototypes for special roles. Adolf Hitler was a proponent of "war winning" weapons and supported projects like the 188 tonne Maus, and even larger 1000 tonne Landkreuzer P. 1000 Ratte and 1500 tonne Landkreuzer P. 1500 Monster. The British, Soviets and US all built prototype designs similar to the Jagdtiger, but none of these saw combat as the need for such a weapon turned out to be extremely limited.
The idea of super heavy tanks saw less development after the war, except in the Soviet Union where some relatively heavy tank prototypes were tested for the Cold War nuclear battlefield. These might be considered super-heavy by the standards of Soviet tank design, where the emphasis was on small size and low weight, but they were no heavier than the standard U.S. and British heavy tanks of the period.
