Tsar Tank: Russia's 27-Foot Tricycle of Doom
In 1914, Russian engineer Nikolai Lebedenko convinced Tsar Nicholas II to fund an armored vehicle with front wheels standing 27 feet tall, taller than a two-story building. The Lebedenko Tank, better known as the Tsar Tank, looked less like a war machine and more like an enormous metal tricycle. Two massive spoked front wheels were supposed to roll over any obstacle, while a smaller rear roller steered the contraption. It mounted multiple machine gun positions and was powered by two captured Maybach aircraft engines.
When the prototype rolled out for testing near Moscow in August 1915, the concept immediately collapsed, literally. While the front wheels could indeed crush trees, the tiny rear wheel promptly sank into soft ground and stuck. The entire 60-ton vehicle became immobilized and no amount of engine power could free it. The Tsar Tank sat abandoned in the forest for years, slowly rusting, until it was finally scrapped in 1923. It remains one of history's most ambitious, and most spectacularly failed, attempts to reinvent armored warfare from scratch.
