The Bomb, Medium Capacity, 22,000 lb (Grand Slam) was a 22,000 lb (10,000 kg) earthquake bomb used by RAF Bomber Command against German targets towards the end of the Second World War. The bomb was originally called Tallboy Large until the term Tallboy got into the press and the code name was replaced by "Grand Slam".
The viaducts were attacked by 617 and 9 squadrons with Tallboys and the first Grand Slams. The Arnsberg viaduct withstood the attack but 100 m (330 ft) of the Bielefeld viaduct collapsed through the 'earthquake effect' of the Grand Slams and Tallboys.

Valentin U-boat pen, with its roof of 4.5 metres of reinforced concrete blown open by a Grand Slam bomb. After the success of the bouncing bomb, Wallis was able to return to his huge bombs, producing first the Tallboy (6 tonnes) and then the Grand Slam (10 tonnes) deep-penetration earthquake bombs.
However, the earthquake bomb idea was continued, initially as the smaller 12,000 lb (5,400 kg) Tallboy bomb, and then the larger 22,000 lb (10,000 kg) Grand Slam bomb, the carrying aircraft being a modified Avro Lancaster, whose performance had improved during the war to the point where it could manage such a load.
The inventor of the first such bomb was the British engineer Barnes Wallis, whose "Upkeep" bouncing bomb was used in the RAF's Operation Chastise of May 1943 to bounce into German dams and explode underwater, with an effect similar to the underground detonation of the later Grand Slam and Tallboy earthquake bombs, both of which he also invented.
