The Avro Lancaster probably is the most famous heavy bomber used by the Royal Air Force during WW II; it came in use in 1942. More than 7.300 bombers were built for the Royal Air Force Bomber Command. One of the most important targets for the RAF was the destruction in the Ruhr area of the dams which supplied electric power to important industrial installations. In order to effectively hit resistent targets such as dams, a dam-breaching rotating bomb was developed, better known as "Bouncing Bomb". A new unit, 617 Squadron, was especially established for this attack and was lead by Wing Commander Guy Gibson. Code-named "Operation Chastise" the attack took place with 19 Lancaster bombers during the night of 16 to 17 may 1943. The first two dams - Mohne and Eder - were successfully destroyed while both others, Ennepe and Sorpe, stood firm.
