A boosted fission weapon usually refers to a type of nuclear bomb that uses a small amount of fusion fuel to increase the rate, and thus yield, of a fission reaction. The neutrons released by the fusion reactions add to the neutrons released due to fission, allowing for more neutron-induced fission reactions to take place.
Kinglet was a boosted fission primary used in several American thermonuclear weapons. [1]The W55 warhead for the UUM-44 SUBROC anti-submarine missile and the W58 warhead for Polaris A-3 were designed to use Kinglet, while the W47 warhead for Polaris A-1/A-2 were retrofitted with Kinglet to overcome the technical issues with the Robin primary the W47 was initially deployed with.
Conducted on May 25, 1951, Item was the first test of an actual boosted fission weapon, nearly doubling the normal yield of a similar non-boosted weapon.In this test, deuterium-tritium (D-T) gas was injected into the enriched uranium core of a nuclear fission bomb.
Orange Herald was a fusion boosted British fission nuclear weapon (called a core-boosted device by the British), comprising a U-235 core containing a small amount of lithium deuteride . [1] [2] 'Herald' was suitable for mounting on a missile, utilizing 117 kg of U-235. However, Britain's annual production of U-235 was only 120 kg at this time ...
Boosted fission weapons increase yield beyond that of the implosion design, by using small quantities of fusion fuel to enhance the fission chain reaction. Boosting can more than double the weapon's fission energy yield. Staged thermonuclear weapons are arrangements of two or more "stages", most usually two. The first stage is typically a ...
The W31 is a boosted fission nuclear bomb. [1] Uses. Nike Hercules missile ... four of the five stockpiled W31 yields were used in the ADM version of the weapon, i.e ...
This is known as a boosted fission weapon. [5] If a fission device designed for boosting is tested without the boost gas, a yield in the sub-kiloton range may indicate a successful test that the device's implosion and primary fission stages are working as designed, though this does not test the boosting process itself.
The W40 nuclear warhead was an American fusion-boosted fission nuclear warhead developed in the late 1950s and which saw service from 1959 to 1972.. The W40 design was reportedly the common Python primary or fission core used by the US B28 nuclear bomb, W28 nuclear warhead, and W49 nuclear warhead.
