11. The Bouncing Bomb
Developed by British engineer Barnes Wallis, the “bouncing bomb” was designed to skip across water and breach German dams during World War II. The weapon, codenamed “Upkeep,” was a 9,250-pound cylindrical mine intended to be dropped from a height of 60 feet, spinning backward to bounce over torpedo nets and detonate upon reaching the dam wall. The most notable use of this bomb was during the Dambusters Raid on the night of 16-17 May 1943, where it successfully breached the Möhne and Edersee dams, causing significant flooding in the Ruhr Valley. Despite its initial success, the bouncing bomb faced challenges in consistent deployment and effectiveness, leading to limited use in subsequent operations.
