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 ...
This means that neutron bombs have a yield range of 1–10 kilotons, with fission proportion varying from 50% at 1 kiloton to 25% at 10 kilotons (all of which comes from the primary stage). The neutron output per kiloton is then 10 to 15 times greater than for a pure fission implosion weapon or for a strategic warhead like a W87 or W88. [70]
A major challenge in all nuclear weapon designs is to ensure that a significant fraction of the fuel is consumed before the weapon destroys itself. The amount of energy released by fission bombs can range from the equivalent of just under a ton to upwards of 500,000 tons (500 kilotons) of TNT (4.2 to 2.1 × 10 6 GJ). [11]
To find the optimum height of burst for any weapon yield, the cube root of the yield in kilotons is multiplied by the ideal H.O.B for a 1 kt blast, e.g. the optimum height of burst for a 500 kt weapon is ~1745 m. [4] An estimate of the size of the damage caused by the 16 kt and 21 kt atomic bombings of Hiroshima and Nagasaki.
An antimatter weapon is a theoretically possible device using antimatter as a power source, a propellant, or an explosive for a weapon.Antimatter weapons are currently too costly and unreliable to be viable in warfare, as producing antimatter is enormously expensive (estimated at US$6 billion for every 100 nanograms), the quantities of antimatter generated are very small, and current ...
Various models of the Mark 6 were roughly 25% lighter than either the Mark 4 or Fat Man, and weighed 7,600 to 8,500 pounds (3,400–3,900 kg). Early models of the Mark 6 used the same 32-point implosion system design concept as the earlier Mark 4 and Mark 3; the Mark 6 Mod 2 and later used a different, 60-point implosion system.
The nominal weight of the bomb is 1,000 pounds (450 kg), although its actual weight varies between 985 pounds (447 kg) and 1,030 pounds (470 kg), depending on fuze options, [1] and fin configuration. [2] The Mk 83 is a streamlined steel casing containing 445 pounds (202 kg) of tritonal high explosive. When filled with PBXN-109 thermally ...
