Did you know that the heaviest tank in history weighed as much as sixty cars? We're talking about the German Panzer VIII Maus, a true steel monster designed to break through any defense. Weighing 188 tons, it was armed with a 128mm cannon. Designed in Germany in 1944, the Maus was intended to breach fortifications, but was too slow. Only two prototypes were built; one was captured by Soviet troops in 1945. No less impressive was the E-100, which developed the idea of a super-heavy tank weighing up to 140 tons. It was developed in parallel with the Maus, but was not completed before Germany's surrender. The Japanese OI super-heavy tank, planned in 1940, would have weighed 150 tons. The British TOG II*, although weighing "only" 81 tons, was dubbed a "land battleship" due to its 10-meter length and its concept for breaching World War I trenches. By 1940, it was already obsolete, but its design was unique. These monsters demonstrated that massive weight doesn't always equate to combat effectiveness. Their production and transportation were a nightmare. The most ambitious project, the German P.1000 Ratte, was planned to weigh 1,000 tons but never saw the light of day.
