The Disney bomb, also known as the Disney Swish, officially the 4500 lb Concrete Piercing/Rocket Assisted bomb was a rocket-assisted bunker buster bomb developed during the Second World War by the British Royal Navy to penetrate hardened concrete targets, such as submarine pens, which could resist conventional free-fall bombs. The Disney could penetrate 16 ft (4.9 m) of solid concrete before detonating. The name is attributed to a propaganda film, Victory Through Air Power, produced by the Walt Disney Studios, that provided the inspiration for the design.
