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.
The PGM-11 Redstone was the first large American ballistic missile.A short-range ballistic missile (SRBM), it was in active service with the United States Army in West Germany from June 1958 to June 1964 as part of NATO's Cold War defense of Western Europe.
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 ...
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 ...
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 ...
Shot Frigate Bird of Operation Dominic on 6 May 1962, was the only U.S. test of an operational ballistic missile with a live nuclear warhead (yield of 600 kilotons), at Johnston Atoll in the Pacific. In general, missile systems were tested without live warheads and warheads were tested separately for safety concerns.
Exercise Desert Rock I during the Buster Dog test. Operation Buster–Jangle was a series of seven (six atmospheric, one cratering) nuclear weapons tests conducted by the United States in late 1951 at the Nevada Test Site.
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 ...
