* The British developed highly specialized bombs for certain missions. The most famous of these was the "Upkeep" bouncing bomb, used for the attacks performed by the elite Royal Air Force (RAF) 617 Squadron on the Moehne, Eder, and Sorpe dams on the night of 16:17 May 1943. The Upkeep weapon was designed by Dr. Barnes Wallis, who had been trained as a structural engineer but turned to aircraft and weapons engineering, becoming well known for his geodetic-framed Vickers Wellington bomber.Upkeep was really a kind of depth charge, and its operation reflected Wallis's knowledge of structures and their weaknesses. It was designed as a 4.2 tonne (9,250 pound) drum, and was carried underneath a modified Lancaster heavy bomber. The bomb was given a 500 RPM backspin before it was released at low altitude over the surface of the water, in front of a dam. It would then skip over the water, run into the surface of the dam, roll down its face, and explode at a predetermined depth. Confinement of the explosion to the face of the dam by water pressure multiplied the effect of the blast.The bombs breached the Moehne and Eder dams. The actual military usefulness of this action is still debated, but the Upkeep weapon worked precisely as designed, even though nothing like it had been done before.
