The Mod 11 variant of the B61 replaced the B53 in the bunker busting role. 50 were retained as part of the 'Hedge' portion of the Enduring Stockpile until completely dismantled in 2011. Was the most powerful US bomb in active service until 1997. Variable yield weapon, most powerful US weapon in active service. Most powerful tested UK boosted fission missile warhead. Most powerful US pure fission bomb, 60 kg uranium, implosion type. Twelve of these may be in a Trident II missile treaty limited to eight. Ten of these were in a MIRVed LGM-118A Peacekeeper. Twelve of these may be in a MIRVed Trident II missile treaty limited to eight. Implosion type plutonium-239 fission bomb (the second of the two nuclear weapons used in warfare).Ħ.2 kg of Plutonium-239, about 1 kg fissioned Gun type uranium-235 fission bomb (the first of the two nuclear weapons that have been used in warfare).Ħ4 kg of Uranium-235, about 1.38% of the uranium fissioned Total weight of nuclear material and bomb was 98.8 - 100.2 kg Variable yield tactical nuclear weapon-mass only 23 kg (51 lb), lightest ever deployed by the United States (same warhead as Special Atomic Demolition Munition and GAR-11 Nuclear Falcon missile).Īn unguided air-to-air rocket armed with a W25 nuclear warhead developed to intercept bomber squadrons. In order of increasing yield (most yield figures are approximate): Since then, the smaller warheads needed to achieve the increased net damage efficiency (bomb damage/bomb mass) of multiple warhead systems have resulted in increases in the yield/mass ratio for single modern warheads.Įxamples of nuclear weapon yields Yields of 5.2 megatons/ton and higher have been reported for large weapons constructed for single-warhead use in the early 1960s. The practical maximum yield-to-weight ratio for fusion weapons ( thermonuclear weapons) has been estimated to six megatons of TNT per metric ton of bomb mass (25 TJ/kg). The yield-to-weight ratio is the amount of weapon yield compared to the mass of the weapon. Because the accuracy of any measurement of the energy released by TNT has always been problematic, the conventional definition is that one kiloton of TNT is held simply to be equivalent to 10 12 calories. An explosive yield of one terajoule is equal to 0.239 kilotonnes of TNT. The explosive yield of a nuclear weapon is the amount of energy released when that particular nuclear weapon is detonated, usually expressed as a TNT equivalent (the standardized equivalent mass of trinitrotoluene which, if detonated, would produce the same energy discharge), either in kilotons (kt-thousands of tons of TNT), in megatons (Mt-millions of tons of TNT), or sometimes in terajoules (TJ).
