In World War II... how many bombs did the US have?

Question

i know that we dropped 2 on Nagasaki and Hiroshima

Answer 1

"The United States expected to have another atomic bomb ready for use in the third week of August [1945], with three more in September and a further three in October. On August 10, Major General Leslie Groves, military director of the Manhattan Project, sent a memorandum to General of the Army George Marshall, Chief of Staff of the United States Army, in which he wrote that "the next bomb . . should be ready for delivery on the first suitable weather after 17 or 18 August." On the same day, Marshall endorsed the memo with the comment, "It is not to be released over Japan without express authority from the President." There was already discussion in the War Department about conserving the bombs in production until Operation Downfall, the projected invasion of Japan, had begun. "The problem now [13 August] is whether or not, assuming the Japanese do not capitulate, to continue dropping them every time one is made and shipped out there or whether to hold them . . . and then pour them all on in a reasonably short time. Not all in one day, but over a short period. And that also takes into consideration the target that we are after. In other words, should we not concentrate on targets that will be of the greatest assistance to an invasion rather than industry, morale, psychology, and the like? Nearer the tactical use rather than other use." "

Answer 2

That was it., and we weren't all that sure that they would work.
As an aside, some credible scientists were concerned about the the first bomb test. They did not know what effect it would have on the atmosphere with all those atoms racing around. The total effects of radiation was also of great concern. We had never tested such a weapon before and were dealing with something we did not have that much knowledge of because we tried to get the bomb as soon as possible so we wouldn't have to make a land invasion of Japan.

Answer 3

The U.S. used the only two atomic bombs it had.

After Hiroshima and Nagasaki there were no more atomic bombs, but the U.S. kept that a secret.

Very soon after the end of WWII the Soviet Union under Stalin began to cause trouble and expand. Stalin behaved himself initially because he did not know the U.S. ran out of atomic bombs.

Answer 4

It is necessary to know exactly at what point in time you are speaking about the bombs. Early on there were three, the first was a test in the New Mexico desert before the two dropped on Japan. There were more in the development porcess at the end of WWII, but not prepared for deployment.

Answer 5

There was a fourth bomb, called "bomb 4" (approriately enough). After WWII we began building atomic bombs as quickly as possible. By 1955, ten years after Hiroshima, we already had a stockpile of over 2000 bombs.

Answer 6

The US had thousands of conventional bombs, but only the two atomic bombs.

Answer 7

apparently, enough.
