After the bombing of Nagasaki, what type of A-bombs were being readied? The Little Boy types were uranium-cored with blast of about 15 kt. The Fat Man types were plutonium-cored with blast of about 21 kt.
This is what wikipedia says about more A-bombs being prepared for Japan:
Groves expected to have another atomic bomb ready for use on August 19, with three more in September and a further three in October.
Then a bit later it says:
Two more Fat Man assemblies were readied, and scheduled to leave Kirtland Field for Tinian on August 11 and 14, and Tibbets was ordered by LeMay to return to Albuquerque, New Mexico, to collect them. At Los Alamos, technicians worked 24 hours straight to cast another plutonium core. Although cast, it still needed to be pressed and coated, which would take until August 16. Therefore, it could have been ready for use on August 19. Unable to reach Marshall, Groves ordered on his own authority on August 13 that the core should not be shipped.
There are sources for all of this in the article. The first one was a brief pdf that was hard to read and I didn't find what I'm looking for in it. And anyway, the paragraphs seem to contradict one another because first it says Groves expected one more in August, then the second paragraphs says two more were scheduled in August, with a third tried but delayed. But both seem to indicate that all further types will be Fat Man (plutonium).
So what types were being readied for August, September, and October? Had America stopped the Little Boy types for some reason?
