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.
During World War II, Japan had several programs exploring the use of nuclear fission for military technology, including nuclear reactors and nuclear weapons.Like the similar wartime programs in Nazi Germany, it was relatively small, suffered from an array of problems brought on by lack of resources and wartime disarray, and was ultimately unable to progress beyond the laboratory stage during ...
A thermobaric bomb is a type of explosive that utilizes oxygen from the surrounding air to generate an intense, high-temperature explosion, and in practice the blast wave typically produced by such a weapon is of a significantly longer duration than that produced by a conventional condensed explosive. The fuel-air bomb is one of the best-known ...
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 bomb consists of a forged steel case with 96 pounds (44 kg) of Composition H6, Minol or Tritonal explosive. The power of the Mk 81 was found to be inadequate for U.S. military tactical use, and it was quickly discontinued, although license-built copies or duplicates of this weapon remain in service with various other nations.
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.
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 energy liberated in the explosion of such a super-bomb is about the same as that produced by the explosion of 1,000 tons of dynamite. This energy is liberated in a small volume, in which it will, for an instant, produce a temperature comparable to that in the interior of the sun. The blast from such an explosion would destroy life in a wide ...
