25 megatonnes of tnt 100 pj. Retired 862 765. Most powerful us weapons ever. Minimum mass content the absolute minimum possible mass for a bomb is determined by the smallest critical mass that will produce a significant yield. The mk 17 was also the largest by area square footage and mass cubic footage. This equates to being the highest yield to weight weapon ever produced.

Fat man was even bigger about 10300 pounds 4670 kg and used a core of plutonium 239 to create a nuclear chain reaction. Known nuclear weapon yieldweight ratios mark one little boy a plug consisting of 252 kilograms 42 of the critical mass was fired into a series of concentric rings containing the remaining 58 348 kilograms of the critical mass. The mk 41 or b41 had a mass of 4800 kg and yield of 25 mt. The length was necessary for the plutonium bullet to pick up adequate speed before reaching the target. This ucrl design was a competitor with the lasl mk 28 to satisfy the class d light weight tn bomb requirement. If the bomb goes off on the ground some of that radiation will be absorbed by the ground and by nearby structures.

About 700 grams completely fissioned out of a total of 60 kilograms of uranium 235 for a efficiency of 12 and a yieldweight ratio of 023 ktkg. Either way the massive ordinance penetrator aptly named considering its 30000 pound or over 13500 kilogram weight is the primary bunker busting bomb in the united states arsenal. A typical thermonuclear warhead may be constructed according to a two stage design featuring a fission or boosted fission primary also called the trigger and a physically separate component called the secondary. Far from little the bomb weighed about 9700 pounds 4400 kg. Weight was around 8000 pounds 3600 kg for the final weapon model. Thin man was 17 feet 52 m long with 38 inch 97 cm wide tail and nose assemblies and a 23 inch 58 cm midsection.

Nuclear weapon nuclear weapon basic two stage design. About 20 short tons 18000 kg. Manufactured 958 659. Virtually all of the blast from a nuclear explosion is the result of the large volume of air that expands when it is suddenly heated by radiation from the bomb. Both primary and secondary are contained within an outer metal case. Since the critical mass for alpha phase plutonium is 105 kg and an additional 20 25 of mass.
