The Earthquake bombs were designed not to strike a target directly, but to impact beside it, penetrate under it, and create a ' camouflet' or large buried cavern at the same time as delivering a shock wave through the target's foundations. Though these bombs might be thought of as 'bunker busters' today, in fact the original 'earthquake' theory was more complex and subtle than simply penetrating a hardened surface. ![]() They had casings of high grade steel, much stronger than the typical WWII bomb so that they would survive hitting a hardened surface, or penetrate deep into the ground. This allowed them to exceed the speed of sound as they fell from 22,000 ft (6,700 m). The designs were very aerodynamic with a tail which caused them to spin. In World War II the British designer Barnes Wallis, already famous for inventing the bouncing-bomb, designed two bombs that would become the conceptual predecessors of modern bunker busters: the five tonne Tallboy and the ten tonne Grand Slam "Earthquake" bombs. They were tested in 19 against the Belgian Fort d'Aubin-Neufchâteau Aircraft delivered bombs World War II United KingdomĪ U-Boat pen after being hit by a Grand Slam - there is a figure standing on the pile of rubble. Röchling shells were bunker-busting artillery shells, developed by German engineer August Cönders, based on the theory of increasing sectional density to improve penetration.
