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.
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.
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.
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.

Even as late as 1954, no boosted weapon had entered into the nuclear-weapons stockpile, and the only use for the Greenhouse Item nuclear test had been for its research results. The "Booster" device was detonated at 6:17 am on May 25, 1951, from a 200-foot-tall (61 m) shot tower on the island of Engebi in the Enewetok Atoll, and its fusion fuel ...

The W33 is the third known model of gun-type fission weapons to have been detonated, and the second as a test explosion. The W33 was tested twice, first in Operation Plumbbob Laplace , on September 8, 1957 with a yield of 1 kilotonne of TNT (4.2 TJ ), [ 10 ] and the TX-33Y2 in Operation Nougat Aardvark on May 12, 1962, with a yield of 40 ...
