military authorities collaborated with utmost secrecy on the project and steadily advanced the development of atomic bombs. government, nuclear physicists, industrial authorities and U. The development of new weapons using nuclear energy, i.
government and the army were rushing to develop an A-bomb by organizing a group of scientists, putting great sums of money and industry into this project. A., scientists who escaped from Europe recommended President Roosevelt to develop atomic bombs prior to Germany. by voluntarily providing information, for fear that Germany would develop the atomic bomb faster and would bring a destructive result. Meanwhile, Great Britain recognized the possibility of producing atomic bombs in 1940 during the World War II, and decided to develop atomic bomb cooperating with the U. That means it is one million times more destructive than conventional bombs fired from ordinary cannons.Īlthough Germany had been ahead of theoretical research in nuclear physics, specialists, mostly of Jewish origin, were expelled from the country by the Nazis in the latter half of 1930s. Compared to weapons with a conventional explosive, the energy of the Hiroshima-type atomic bomb, using 12.5 kilogram of uranium-235 (as big as a softball), is equivalent to 15 kilotons of TNT (trinitrotoluene). Nuclear weapons are developed for genocide and mass destruction, utilizing the energy released when nuclear fission occurs.
