How much destruction was caused by the atomic bomb fat man?

Answer 1

If you consider the total cost of the Manhattan Project ($2,000,000,000) and divide that over the 4 atomic bombs built over WW2 (Trinity, Little Boy, Fatman, and one finished about the time Japan surrendered and thus not used); each bomb cost $500 million. However as most of the expenses on the Manhattan Project was for infrastructure (e.g. enrichment plants, reactors, plutonium reprocessing plants) that could be used to make more bombs, actual production and delivery costs for Fatman was much less: probably well under $1 million.

Answer 2

None. 'Fat Man's trigger mechanism used Composition B, a high explosive common in military use at the time, as its 'primer', but this was, obviously, only a detonator. - using a sphere of explosives to compress a plutonium charge beyond the super-prompt critical point. The internet is somewhat reluctant to describe how much detonating explosive was actually present, but it probably comprised the bulk of the bomb's volume - the plutonium payload was only 6.2 kilograms.

Alternatively, the yield of Fat Man was ~88 terajoules, equivalent to 21,000 tons of TNT (or 75 million standard 'sticks')

Answer 3

The bombing of Nagasaki on August 9th was the last major act of World War Two and within days the Japanese had surrendered. Nagasaki was not America's primary target. This was Kokura but cloudy condition was a no go.

'Fat Man' was a very effective bomb. Its blast was bigger than 'Little Boy's' but its impact was reduced by the natural topography of the city. An area about 2.3 miles by 1.9 miles was destroyed but other parts of the city were saved from the blast. Curiously, the city's train service was not interrupted and the fire damage that followed Hiroshima did not occur in Nagasaki as many parts of the city were broken up by water. The fires simply could not cross these gaps and they burned out, however, considerable damage was done to the city. The horrific injuries suffered at Hiroshima were also witnessed at Nagasaki. The city's medical facilities were not totally destroyed by 'Fat Man' as at Hiroshima but nobody was capable of coping with those who were injured in the blast.

Answer 4

Around 10 thousand pounds. It was also 10 ft long and 5 feet wide.

Answer 5

The class of nuclear bombs known as 'Fat Man' weighed 10,300 pounds and had a yield of around 22 kilotons. A Fat Man bomb was dropped on Nagasaki, Japan on August 9, 1945.
