The cover to the Project 4.1 Final Report, "Study of Response of Human Beings Accidentally Exposed to Significant Fallout Radiation" Project 4.1 was the designation for a medical study and experimentation conducted by the United States of those residents of the Marshall Islands exposed to radioactive fallout from the 1 March 1954 Castle Bravo nuclear test at Bikini Atoll, which had an ...
Trinity, part of the Manhattan Project, was the first ever nuclear explosion. The United States performed nuclear weapons tests from 1945 to 1992 as part of the nuclear arms race. By official count, there were 1,054 nuclear tests conducted, including 215 atmospheric and underwater tests. [1] [notes 1]
Mushroom cloud from China's first nuclear test, Project 596. China tested its first nuclear weapon device ("596") in 1964 at the Lop Nur test site. The weapon was developed as a deterrent against both the United States and the Soviet Union. Two years later, China had a fission bomb capable of being put onto a nuclear missile.
Thus, Minot Air Force Base stored and maintained a ready arsenal of nuclear bombs, nuclear warheads, and associated delivery systems, including the AGM-129 Advanced Cruise Missile. [ 5 ] The AGM-129 ACM was fielded in 1987 as a stealthy cruise missile platform to deliver the W80-1 variable yield nuclear warhead.
The air-borne nuclear detonation raised the surface seawater temperature by 99,000 °F (55,000 °C), created blast waves with speeds of up to 26 ft/s (7.9 m/s) [unreliable source?], and shock and surface waves up to 98 ft (30 m) high. Blast columns reached the floor of the lagoon, which is approximately 230 ft (70 m) deep.
The Rocky Flats Plant was a United States manufacturing complex that produced nuclear weapons parts near Denver, Colorado. [2] The facility's primary mission was the fabrication of plutonium pits, [3] the fissionable part of a bomb that produces a nuclear explosion.

The MET was the first bomb core to include uranium-233 (a rarely used fissile isotope that is the product of thorium-232 neutron absorption), along with plutonium; this was based on the plutonium/U-235 pit from the TX-7E, a prototype Mark 7 nuclear bomb design used in the 1951 Operation Buster-Jangle Easy test.
