Best Answer

Actual work was begun in the US in 1942 and it was finished in 1945, therefor about 3 years.

To assemble the early bombs from a kit in the field took about 3 days with an assembly crew of 40 to 50 men working around the clock.

How many nuclear bombs are there left?

You can not be really very sure how many are left, because when there is war, they will just make more atom bombs if they need some more.--------------------------------------------------------------------------------------------------------------------------------------Completely wrong. If the U.S. and Russia fought a nuclear war, the war would be over in a couple of hours at most and it takes months to manufacture a nuclear weapon. Also the war damage to the nuclear weapons production system would take years to repair before any manufacturing could begin again. There would be no chance to make any more.If the nuclear war was fought by other countries, perhaps they could make more but all the other countries nuclear weapons put together are less than 1/4 of those that either the U.S. or Russia have.
