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 Project Manhattan, was the first ever nuclear explosion. The nuclear weapons tests of the United States were performed from 1945 to 1992 as part of the nuclear arms race. The United States conducted around 1,054 nuclear tests by official count, including 216 atmospheric, underwater, and space tests.
On 29 August 2007, six AGM-129 ACM cruise missiles, each loaded with a W80-1 variable yield nuclear warhead, were mistakenly loaded onto a United States Air Force (USAF) B-52H heavy bomber at Minot Air Force Base in North Dakota and transported to Barksdale Air Force Base in Louisiana.
Lazard's report on the estimated levelized cost of energy by source (10th edition) estimated unsubsidized prices of $97–$136/MWh for nuclear, $50–$60/MWh for solar PV, $32–$62/MWh for onshore wind, and $82–$155/MWh for offshore wind. [83] However, the most important subsidies to the nuclear industry do not involve cash payments.
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 Mk-21 design project began on 26 March 1954 (just three weeks after Bravo), with production of 275 weapons beginning in late 1955. Romeo , relying on natural lithium, was rapidly turned into the Mk-17 bomb , the first deployable US thermonuclear weapon , [ 10 ] and was available to strategic forces as an Emergency Capability weapon by mid-1954.
H-912 transport container for Mk-54 SADM. A suitcase nuclear device (also suitcase nuke, suitcase bomb, backpack nuke, snuke, mini-nuke, and pocket nuke) is a tactical nuclear weapon that is portable enough that it could use a suitcase as its delivery method.
Nuclear artillery is a subset of limited-yield tactical nuclear weapons, in particular those weapons that are launched from the ground at battlefield targets. Nuclear artillery is commonly associated with shells delivered by a cannon , but in a technical sense short-range artillery rockets or tactical ballistic missiles are also included.
