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.
The Mark 18 nuclear bomb was a follow-on to the Mark 6 and Mark 13, utilizing a fissile pit assembly with around 60 kilograms of HEU and delivering a yield of 500 kilotons, the largest pure-fission (non-thermonuclear) bomb design ever developed by the US.
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 ...
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]
The Mark 1 version with the Green Grass warhead weighed 7,250 pounds (3,290 kg). ... (RAF) as 500 kilotons of TNT equivalent (2.1 PJ), but the designers' estimate was ...
It weighed 6,500–6,750 pounds (2,950–3,060 kilograms), [2] and was about 11 feet, 8 inches long (3.556 meters) [2] with a diameter of 35 inches (89 cm). [2] The design is an improved Mark 15 nuclear bomb design (the TX-15-X3 design and Mark 39 Mod 0 were the same design). The Mark 15 was the first lightweight US thermonuclear bomb.
High altitude carpet-bombing with much smaller 500-to-2,000-pound (230 to 910 kg) bombs delivered via heavy bombers such as the B-52, B-2, or the B-1 is also highly effective at covering large areas. [10] The MOAB is designed to be used against a specific target, and cannot by itself replicate the effects of a typical heavy bomber mission.
The W30 Mod 1, 2, and 3 for Talos all had yields of 5 (sometimes more precisely reported as 4.7) kilotons. The TADM warhead was produced from 1961 and saw service until 1966. There were two variants, the W30 Mod 4 Y1 with 0.3 kiloton yield (300 tons TNT) and the W30 Mod 4 Y2 with 0.5 kiloton (500 tons TNT) yield. 300 TADM W30s were produced ...
