context_page_description: 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.
  Devised by Royal Navy Captain Edward Terrell, the bomb was fitted with solid-fuel rockets to accelerate its descent, giving it an impact speed of 990 mph — substantially beyond the 750 mph free-fall impact velocity of the 5 tonne Tallboy "earthquake" bomb for comparable purposes.
  The Disney could penetrate 16 ft 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.
  The Disney bomb saw limited use by the United States Army Air Forces in Europe from February to April 1945. Although technically successful, it initially was insufficiently accurate for bunker targets. It was deployed late in the war and had little effect on the Allied bombing campaign against Germany.
