Why did US use diff sort of bomb on two different cities in Japan???

Answer 1

That was all they had.

.

Answer 2

Both the bombs were manufactured without experience .... when they were built neither design had been tested, so they used different designs to make certain one of them would work. Both did.

But each of them was based on the bomb the government tested at the Trinity Site in New Mexico, from a platform, which wasn't constructed to be dropped from a bomber.

Just a matter of redundancy, hedging bets, those two different designs.

After re-reading your question I think maybe you're asking why the US dropped the atomic bomb on Japan.

It was that kind of war. If the Japanese had developed the bomb, they'd have dropped it, certainly. Same with the Germans, Soviets.

The US dropped the bomb on Japan because it was the easiest, fastest way to end the war with the most economical expenditure of US lives.

Same as any other country would have done under the circumstances.

Answer 3

There weren't but six bombs. If you'll notice, the US policy during the war was to duplicate where possible. The B17 and B24 bombers were meant to have two similar designs in production. The medium bombers B25 and B26 were sister systems. Fighter planes did the same. If one worked and the other didn't, they could shift production. If both worked, any minor peculiarities could be taken care of, and production was still maximized. If you're going to make a uranium bomb and a plutonium bomb, which makes some sense, why not try one of each instead of two of one, especially with a total of six bombs in inventory.

Answer 4

I in simple terms hate the thought-approximately ANY nukes because of the fact now investigate the worldwide. Even Pakistan has nukes yet I wager Japan and Germany would not be waiting to get one without anger from different worldwide places! the consequence of the A bomb are nonetheless felt in Japan on the instant. i know that. I in simple terms want what reasons much less annoying to human beings.

Answer 5

The bombs were different because of the availability of fissionable material. The manufacturing processes for U235 and Plutonium were still under development at the time. The bombs used on Japan were all that were readily available at that time.

Answer 6

Fat Boy and Little Boy (Hiroshima and Nagasaki, respectively) were two different designs. I guess the scientists and generals figured this would be a good chance to do some research at the same time.

Answer 7

1. We dropped the bomb to save even more lives and end the war sooner, because we would have had to invade Japan.

2. To let U.S.S.R. know that we had them.

Answer 8

Research and development

Answer 9

Really! are u sure ?

Well, maybe it is their tactics and part of the plan.
