An 18 kilotons of TNT (75 TJ) land-surface type shot was detonated on a platform at the northern tip of Runit, Enewetak in the second of the 35 tests for Operation Hardtack I. [4]: 2 The initial cloud from the explosion reached as high as 19,000 feet (5.79 km) within the first ten minutes, and settled at around 15,000 feet (4.57 km) by 20 ...
The Mark 21 design continued to be improved and the Mark 36 device started production in April 1956. [2] In 1957, all older Mark 21 bombs were converted to Mark 36 Y1 Mod 1 bombs. A total of 920 Mark 36 bombs were produced as new build or converted from the 275 Mark 21 bombs produced earlier.
Log–log plot comparing the yield (in kilotonnes) and mass (in kilograms) of various nuclear weapons developed by the United States.. The explosive yield of a nuclear weapon is the amount of energy released such as blast, thermal, and nuclear radiation, when that particular nuclear weapon is detonated, usually expressed as a TNT equivalent (the standardized equivalent mass of trinitrotoluene ...
Trinity-Gadget was the first ever pure-fission nuclear device to be detonated, with an estimated yield of 25 kilotons. The first task of a nuclear weapon design is to rapidly assemble a supercritical mass of fissile (weapon grade) uranium or plutonium. A supercritical mass is one in which the percentage of fission-produced neutrons captured by ...
The crew's final view of the aircraft was in an intact state with its payload of two Mark 39 thermonuclear bombs still on board, each with yields of 3.8 megatons. [b] Sometime between the crew ejecting and the aircraft crashing, the two bombs separated from the aircraft. [7] The pilotless aircraft broke up in the air shortly after the crew ejected.
53-58 torpedo with 10 kilotons RDS-9 warhead; 65-73 torpedo with 20 kilotons; VA-111 Shkval with 150 kilotons; Bombs RDS-1, 22 kiloton bomb. Tested 29 August 1949 as "First Light" (Joe 1). Total of 5 stockpiled; RDS-2, 38 kiloton bomb. Tested 24 September 1951 as "Second Light." The RDS-2 was an entirely Russian design, delayed by development ...
The B61 is of the variable yield ("dial-a-yield" in informal military jargon) design with a yield of 0.3 to 340 kilotons in its various mods ("modifications"). It is a Full Fuzing Option (FUFO) weapon, meaning it is equipped with the full range of fuzing and delivery options, including air and ground burst fuzing, and free-fall, retarded free ...
The design used an upgraded engine from Rocketdyne that allowed the missile to carry the 6,900 lb (3,100 kg) W39 and its reentry vehicle to a range of about 175 miles (282 km). Redstone's prime contractor was the Chrysler Corporation.
