'''Little Boy''' was one of the two original [[American]] designs for the [[atomic bomb]] developed at [[Los Alamos]] during [[World War II]]. The other design was called [[Fat man]].

Little boy consisted of two masses of Uranium 235 as radioactive material. A "gun-assembly method" ignited the bomb as follows: one subcritical mass of uranium was fired at another, and together they reached a critical mass to set off a nuclear explosion.
