TNT equivalent is a convention for expressing energy, typically used to describe the energy released in an explosion.The ton of TNT is a unit of energy defined by convention to be 4.184 gigajoules (1 gigacalorie), [1] which is the approximate energy released in the detonation of a metric ton (1,000 kilograms) of TNT.
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 ...
The casting of the TNT was performed on site and began two years in advance of the test. Molten TNT was poured into special 12-by-12-by-4-inch (300 mm × 300 mm × 100 mm) rectangular moulds and allowed to cool for 5 hours, producing smooth caramel-coloured rectangular blocks.
The term "thousand-bomber raid" was used to describe three night bombing raids by the Royal Air Force against German cities in summer 1942 during World War II. [1]The term was a propaganda device, whereby Arthur Harris reached the number of bombers by including not only bombers that were currently operational as part of RAF Bomber Command, but also aircrews from Operational Training Units to ...
Other smaller tests include Air Vent I and Flat Top I-III series of 20 tons TNT at Nevada Test Site in 1963–64, Pre Mine Throw and Mine Throw in 1970–1974, Mixed Company 1 & 2 of 20 tons TNT, Middle Gust I-V series of 20 or 100 tons TNT in the early 1970s, Pre Dice Throw and Pre Dice Throw II in 1975, Pre-Direct Course in 1982, SHIST in ...
The largest nuclear weapon ever detonated, the Tsar Bomba of the USSR, which released an energy equivalent of over 50 megatons of TNT (210 PJ), was a three-stage weapon. Most thermonuclear weapons are considerably smaller than this, due to practical constraints from missile warhead space and weight requirements. [ 17 ]
In the US, the Presidential Emergency Satchel is always handled by a nearby aide unless the President is near a command center. The decision rests with the Prime Minister in the United Kingdom . Information from China is unclear, but "the launch of nuclear weapons is commonly believed to rest with the Central Military Commission of the Chinese ...
General-purpose (GP) bombs use a thick-walled metal casing with explosive filler (typically TNT, Composition B, or Tritonal in NATO or United States service) comprising about 30% to 40% of the bomb's total weight. The British term for a bomb of this type is "medium case" or "medium capacity" (MC).
