For comparison, Tsar Bomb, the largest nuclear weapon ever detonated, reacted an estimated yield of 50 megatons, which required the use of tens of kilograms[citation needed] of fissile material (Uranium/Plutonium) (hundreds for the full-yield 100 megaton design), and two tons of lithium deuteride (fusion fuel).
