The attack on German dams was carried out on May 16 - 17, 1943 during the height of the Second World War with the aim of damaging and destroying as much of Germany's industry as possible.
Crew members used specially developed 'bouncing bombs' code named Upkeep and designed by Barnes Wallis.
The pilots flew at 100ft in the night, blasting the Mohne and Eder dams, causing major flooding in the western Ruhr Valley.
Two hydroelectric power stations, factories and mines were destroyed and damaged, while around 1,600 people drowned.
The impact of the raid made front page news across the world and became better known as the Dambusters Raid.
However critics say it was a propaganda and morale boost to Allies after the Germans were able to rebuild the dams, which took five years to build, in just five months.
