Later in the war, Barnes Wallis made bombs based on the "earthquake bomb concept", such as the 6-ton Tallboy and then the 10-ton Grand Slam, although these were never dropped from more than about 25,000 feet (7.6 km). Even from this relatively low altitude, the earthquake bomb had the ability to disrupt German industry while causing minimum ...
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 bomb was similar to a large version of the Tallboy bomb but a new design and closer to the size that its inventor, Barnes Wallis, had envisaged when he developed the idea of an earthquake bomb. It was the ...
Barnes Wallis was born in Ripley, Derbyshire, to general practitioner Charles George Wallis (1859–1945) and his wife Edith Eyre (1859–1911), daughter of Rev. John Ashby. The Wallis family subsequently moved to New Cross , south London, living in "straitened, genteel circumstances" after Charles Wallis was crippled by polio in 1893. [ 6 ]
Tallboy or Bomb, Medium Capacity, 12,000 lb was an earthquake bomb developed by the British aeronautical engineer Barnes Wallis and used by the Royal Air Force (RAF) during the Second World War. [a] At 5 long tons (5.1 t), it could be carried only by a modified model of the Avro Lancaster heavy bomber. It proved to be effective against large ...
The British "Victory Bomber" was a Second World War design proposal by British inventor and aircraft designer Barnes Wallis while at Vickers-Armstrongs for a large strategic bomber. This aircraft was to have performed what Wallis referred to as "anti- civil engineering " bombing missions and was to have carried his projected 22,000 lb (10,000 ...
The T-12 was a further development of the concept initiated with the United Kingdom's Tallboy and Grand Slam weapons developed by British aeronautical engineer Barnes Wallis during the Second World War: a hardened, highly aerodynamic bomb of the greatest possible weight designed to be dropped from the highest possible altitude. Penetrating ...
In World War II, the British designer Barnes Wallis, already famous for inventing the bouncing bomb, designed two bombs that would become the conceptual predecessors of modern bunker busters: the five tonne Tallboy and the ten tonne Grand Slam. These were "Earthquake" bombs—a concept he had first proposed in 1939. [3]
The devices, developed by British war-time "Dambuster" engineer Barnes Wallis, are similar to the bombs used to destroy German dams during the war. Divers retrieve World War Two 'bouncing bombs ...
