Grand Slam Bomb

Continuing Display

Kelham Island Museum

The Grand Slam Bomb is the heaviest bomb in the world, weighing 10 tonnes. They were produced by Vickers & Co, Sheffield, at their River Don Works during the Second World War.

 

It was designed by Sir Barnes Wallis, a British Aeronautical Engineer, who also created the Bouncing Bomb used in the Dambusters Raid. The Grand Slam Bomb was used by RAF Bomber Command against strategic targets such as bridges and viaducts, railways and U-boat shelters. Only 30 to 40 of the bombs were ever made and they were only used during 1945, the last year of the war.

The main portion of the Grand Slam Bomb, without its lightweight tail, can be seen at the museum.
