How many atomic bombs did the US drop and the end of World War 2?

Answer 1

• As of August 9, 1945 the US had built a total of 3 atomic bombs and exploded all of them.
• As of August 14, 1945 the US had built another bomb which arrived in San Francisco on August 18, 1945; but as Japan was surrendering this bomb was returned to Los Alamos unused.
• The US had production plans and capability to build another 20 atomic bombs before the end of 1945.
• As of the end of Operation Crossroads in the summer of 1946 the US had built a total of 9 atomic bombs and exploded 5 of them.
• At the peak of the cold war the US had built several 10s of thousands of atomic bombs, exploded over a 1000 of them in test shots, and stockpiled more than 10000 of them. (Note: this counts only the high yield "strategic" weapons, at the same time the US had stockpiled roughly 30000 low yield "tactical" weapons. these were eliminated in the 1980s.)

Answer 2

The USA dropped two bombs, both of which where on Japan. the smaller of the two was dropped on Hiroshima. The larger of the two was dropped on Nagasaki, even though it didn't look like that was so. the reason there was more destruction in Hiroshima then Nagasaki is because the shape of the land. Hiroshima is flat and Nagasaki is in a valley that is kinda like a bowl.
