11. The Great Panjandrum
The Great Panjandrum was a British experimental weapon developed during World War II, designed to breach the heavily fortified Atlantic Wall defenses. It consisted of two large, rocket-propelled wheels connected by a drum filled with explosives. The plan was to launch it from a landing craft, allowing it to roll onto the beach and detonate upon impact with enemy fortifications. However, during testing, the Panjandrum proved highly unpredictable, often veering off course and posing significant risks to personnel. As a result, it was never used in combat.
