In July 1962, the US carried out the Starfish Prime test, exploding a 1.44 Mt (6.0 PJ) bomb 400 kilometres (250 mi; 1,300,000 ft) above the mid-Pacific Ocean.This demonstrated that the effects of a high-altitude nuclear explosion were much larger than had been previously calculated.
The EBW was invented by Luis Alvarez and Lawrence Johnston for the Fat Man–type bombs of the Manhattan Project, during their work in Los Alamos National Laboratory.The Fat Man Model 1773 EBW detonators used an unusual, high reliability detonator system with two EBW "horns" attached to a single booster charge, which then fired each of the 32 explosive lens units.
The powered flight portion can last from a few tenths of seconds to several minutes and can consist of multiple rocket stages. [13] Internal computers keep the missile aligned on a preprogrammed trajectory. [12] On multi-stage missiles, stage separation (excluding any post-boost vehicles or MIRV bus) occurs primarily during the boost phase.
Primary views of an R-7 Semyorka, the world's first ICBM and satellite launch vehicle. The first practical design for an ICBM grew out of Nazi Germany's V-2 rocket program. . The liquid-fueled V-2, designed by Wernher von Braun and his team, was then widely used by Nazi Germany from mid-1944 until March 1945 to bomb British and Belgian cities, particularly Antwerp and Lond
The value of an egg-shaped primary lies apparently in the fact that a MIRV warhead is limited by the diameter of the primary—if an egg-shaped primary can be made to work properly, then the MIRV warhead can be made considerably smaller yet still deliver a high-yield explosion—a W88 warhead manages to yield up to 475 kt with a reentry vehicle ...
A typical specification for heavy civil defence shelter in Europe during the Cold war was an overhead explosion of a 500 kiloton weapon at the height of 500 meters. Such a weapon would be used to attack soft targets (factories, administrative centres, communications) in the area.
Airburst effect from 40mm round on dummy soldiers. An airburst round is a type of tactical anti-personnel and anti-aircraft explosive ammunition, typically a shell or grenade, that detonates in midair, causing air burst effect fragment damage to enemy personnel or aircraft (notably comparably unsophisticated unmanned aircraft systems such as modified racing drones).
In Utah, simple possession of a dry ice bomb or similar pressurized chemical reaction bomb is a second-degree felony. [16] In Colorado, the creation of a dry ice bomb is considered illegal due to interpretation as "possession of an explosive device" [citation needed] Leaving an unexploded dry ice bomb can be construed as public endangerment.
