Bythe Germans were ahead in the race for the atomic bomb.

Manhattan project ww2

First RaLa test using exploding-bridgewire detonators. First stages of K are charged with uranium hexafluoride gas. First Hanford plutonium arrives at Los Alamos.

Alsos Mission captures German experimental nuclear reactor at Haigerloch. First meeting of the Target Committee. Second meeting of the Target Committee, at Los Alamos. Third meeting which works to finalize the list of cities on which atomic bombs may be dropped: KokuraHiroshimaNiigata and Kyoto.

Stimson drops Kyoto from the target list. Metallurgical Laboratory scientists under James Franck issue the Franck Report arguing for a demonstration of the bomb before using it against civilian targets. Oppenheimer recommends to Groves that gun-type design be abandoned and the uranium used to make composite cores.

Stalin feigns little surprise; he already knows this through espionage. General Carl Spaatz is ordered to bomb one of the targets: Hiroshima, Kokura, Niigata or Nagasaki as soon as weather permitted, some time after August 3. Potsdam Declaration is issued, threatening Japan with "prompt and utter destruction".

B Enola Gay drops Little Boya gun-type uranium weapon, on the city of Hiroshima, the primary target. B Bockscar drops a Fat Man implosion-type plutonium weapon on the city of Nagasaki, the secondary target, as the primary, Kokura, is obscured by cloud and smoke.

Due to the enormous expense and slow production rates for explosive material, no further tests were conducted. The Manhattan Project was the Allied effort to develop the atomic bomb during World War II.

Led by Maj. Gen. Leslie Groves and J. Robert Oppenheimer, it developed research facilities across the United States. The Project was successful and made the atomic bombs used at Hiroshima and Nagasaki. On.
