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.
Gun-type fission weapon . Date: September 2007: Source: Based on an illustration by FastFission (Image:Gun-type Nuclear weapon.png) and a modified version by Howard Morland (Image:Gun-Type Fission Weapon.png). The bullet and the target were slighty modified (the bullet was a stack of rings). Author

Orange Herald fireball and subsequent mushroom cloud, film reel captured from a trailing aircraft. Orange Herald was a British nuclear weapon, tested on 31 May 1957.At the time it was reported as an H-bomb, although in fact it was a large boosted fission weapon and remains to date, the largest fission device ever detonated.
The first time gun-type fission weapons were discussed was as part of the British Tube Alloys nuclear bomb development program, the world's first nuclear bomb development program. [1] The British MAUD Report [ 2 ] of 1941 laid out how "an effective uranium bomb which, containing some 25 lb of active material, would be equivalent as regards ...
