How much did the atomic bombs 'Little Boy' and 'Fatman' weigh?
The Little Boy weapon which was the first of the atomic bombs that was deployed (and was dropped on Hiroshima) weighed some 8,818.49 pounds, or 4,000 kilograms. A link is provided below.

Bad Answer Jul 16 1945 Trinity 19 Kilotons Test Aug 6 1945 Little Boy 15 Kilotons Bombing of Hiroshima, Japan Aug 9 1945 Fat Man 21 Kilotons Bombing of Nagasaki, Japan … Good Answer I assume when you say "the atomic bomb," you're talking about the ones dropped on Japan during WWII. The numbers above have nothing to do with the weight of the bombs used--they're the equivalence of TNT to achieve the same blast. The weight of the bombs dropped were a little less than five tons (ten thousand pounds) each, but most of the weight was casing and other material. The actual material that exploded only weighed a few pounds. Today, tactical nuclear bombs weigh less than a hundred pounds and can be carried and set up and used by a single soldier.
They were the names given to bombs. Research the Manhattan project.
It depends on the efficiency. America makes it with just 6kg ,while other need more\n
This varies with design. The lightest is in the range of 50 pounds, the heaviest was over 500 tons. Exact weights for many devices are typically classified. The 3 devices ex…ploded in ww2 weighed roughly 5 tons each.
It depends on the size of the bomb
There was no atomic bomb called Big Boy . Perhaps you are confusing it with a restaurant chain that bombed :-) The two atomic bombs used in combat were Little Boy & Fat …Man , their approximate weights were 9,000 pounds & 10,000 pounds respectively.
If you mean the power (In terms of similar to how much Kilotons ofTNT), then it is fatman is about 22kT whereas little boy is about13kT. If you mean which has created more cas…ualties, then it is littleboy (Due to population / geographical condition of 2 differentplaces and the fact that fatman was dropped almost 2 miles offtarget, not because little boy is more powerful than fatman.)
There was no single inventor of the Little Boy gun bomb method, asthat method was an obvious means of assembling a supercriticalmass. Seth Neddermeyer was the inventor of the …implosion method for theFatman to assemble a supercritical mass fast enough to prevent afizzle when using reactor produced plutonium. However he was unableto make it work and George Kistiakowsky was called in. GeorgeKistiakowsky invented the actual shaped charge explosive lensesystem that was used in both the Gadget and the Fatman.
the japenese bombs in world war two. first and second :))
I don't know if you mean size and weight or the cost of the little boy bomb. The atomic bombs cost over 2 Billion Dollars. Divide that by three and you will get the individu…al cost of the three bombs they built. The real cost was the lives who were ended and the lives which were devastated by the radiation poison and later the Cold war. . 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 Little Boy was much less: probably well under $1 million.
In US in WW2
12.5 mega tons Wrong. Little Boy's yield is generally accepted to be 16 kilotons.
In Nuclear Weapons
Only two person knew about the mission's details. The rest of thecrew learned of the destruction when the weapon detonated. Theycould believe what they saw.
In Hiroshima and Nagasaki Atomic Bombings
Little boy-9900 pounds Fat man-10,213 pounds
In US in WW2
Little Boy weighed 4.85 tons and had an explosive yield of about 15 kilotons TNT equivalent. If you really want Little Boy's weight expressed in kilotons it was 0.0…0485 kilotons .
In Nuclear Weapons
The specifications reveal the use of four canisters of cordite (synthetic propellant) in the Little Boy (guntype uranium device). Unclassified details list 4 silk bags, eac…htwo pounds, for a total of 8 pounds of conventionalexplosive, plus their primers. "It took Parsons 15 minutes to load the four cordite canistersinto the gun chamber of Little Boy, which when fired would assembletwo halves of the U-135 to make up the critical mass needed to[sustain] a chain reaction." Note: Cordite is a family of smokeless propellants developed and producedin the UK, beginning in 1889 to replace gunpowder as a militarypropellant. However, cordite is now obsolete since it has beenreplaced by more modern propellants. Note: Implosion type plutonium devices, such as the Fat Man dropped on Nagasaki, used explosive "lenses" made of the explosivesComposition B (TNT and RDX) and Baratol (TNT and barium nitrate).
