(40,742 posts)Our arsenal of the uranium "gun type" bombs was five. These were dangerous and discontinued because uranium enrichment was very expensive and they were the sort of munition that could go off by accident in a fire, plane crash, lightening strike, etc. Oops, there goes your air base. In a plutonium bomb, if the detonation of the conventional explosive is not symmetrical (which it would not be in any accident) then the chunks of plutonium core simply go bouncing off unexploded, leaving a radioactive mess to clean up, but no nuclear explosion.
At the time of the Trinity test all the tooling was in place to build plutonium implosion bombs at a rate of two a month. The plutonium production reactors at Hanford had been built to have greater production capacity than anything the Germans might conceivably have built. By 1950 the USA was already replacing the 120 "Fat Man" Mk-III plutonium bombs we'd built with new, improved designs.
By the time of Eisenhower's presidency the USA already had hundreds of nuclear bombs and by the end of his presidency we had thousands.
