“Little Boy” was the codename for the atomic bomb dropped by the United States on the Japanese city of Hiroshima on August 6, 1945, during World War II. It was a gun-type fission weapon using uranium-235.
It was the first nuclear weapon used in warfare. Three days later, on August 9, 1945, the second atomic bomb, “Fat Man” (a plutonium implosion-type bomb), was dropped on Nagasaki.
The first nuclear test ever conducted was the “Trinity” test, which took place on July 16, 1945, in New Mexico, USA. It tested a plutonium implosion device similar to “Fat Man”. North Korea conducted its first nuclear test much later, in 2006. Fusion bombs are typically much more powerful than fission bombs.
