Uranium ore produces U-235 and U-238. U-238 can be made into Plutonium
by putting it in a reactor, fool. Thus, the captured German uranium
supplied to the Manhatten project could have been used with any of the
three A-bombs detonated: Trinity, Little Boy, or Fat Man.


The Hiroshima bomb was a uranium weapon, no
plutonium was involved and the materials used in the
enrichment were already in the pipeline when U-234
surrendered.

The USA had hundreds of tons of Uranium oxide in the
enrichment and reactor streams from many sources including
hundreds of tons from the Congo mines and stocks captured
in Belgium in 1944. The 0.5 ton German shipment was
a small portion that simply didnt have time to make it through
the system


The fact that captured German uranium was supplied to the Manhatten
Project:

BEFORE any of the bombs were detonated. This does not count the 560kg
of uranium seized from German U-boat of which 4 kg of U-235 could have
been extratced.

Only if the mechanisms existed for 100% extraction, which it didnt.

A small amount, but a contributor to Little Boy which
recent information suggests was one-fifth German (or 12kg).

Highly unlikely given the timelines involved, they started enrichment
at Oak Ridge 2 years before the bomb was constructed, at best
the German shipment could only have arrived weeks ahead of the
bomb construction. Its more likely to have been part of the
weapons assembled in 1948 than 1945

As for Fat Man, I have no idea. All the photos of the German language
warning labels near the tail fins are too small to read.


Given that a large portion of the scientists working at
Los Alamos were German jews the presence of german
language labels is rather unsurprising.
