The Avro Lancaster was the most famous RAF heavy bomber of the 2nd World War and went into service in 1942. More than 7,300 of these machines were built for RAF Bomber Command. One of the most important RAF targets was the destruction of the Ruhr dams that supplied important industrial installations with power. In order to accurately attack such robust targets as dams or barrages a rotating bomb was developed which was better known as the bouncing bomb. For this attack a special new unit was set up, 617 Squadron under the command of Wing Commander Guy Gibson. Code-named Operation Chastise this raid took place with 19 Lancaster bombers on the night of 16th to 17th May 1943. The first two dams - Mohne and Eder - were successfully destroyed, whereas the other two - Ennepe and Sorpe withstood the attack.
