Grand Slam - Ten-Ton Bomb

The Grand Slam was a 22,000 lb (10,000 kg) earthquake bomb used by RAF Bomber Command against strategic targets during the Second World War. It was the most powerful non-atomic bomb used in the war.

Known officially as the Bomb, Medium Capacity, 22,000 lb, it was a scaled-up version of the Tallboy bomb and closer to the original size that the bombs' inventor, Barnes Wallis, had envisaged when he first developed his earthquake bomb idea. It was also nicknamed "Ten ton Tess"

Grand Slam bombs were used between 14 March and 19 April, 1945 against nine strategically important German targets including the Schildesche railway viaduct near Bielefeld, the Arnsberg railway viaduct, the Nienburg railway bridge, submarine pens near Bremen and German gun batteries on the island of Heligoland.

The Grand Slam campaign played a key role in helping to speed up the defeat of German forces in the final two and half months of the war. Almost 100 Grand Slam bombs were produced of which 42 were used in nine major Bomber Command sorties. Today only five publicly accessible examples survive - in the RAF Museum in north-west London, Brooklands Museum in Surrey, Dumfries and Galloway Aviation Museum, the Battle of Britain Memorial Flight Visitor Centre at RAF Coningsby in Lincolnshire and Kelham Island Museum, Sheffield.
