A 1997 czech movie Knoflíkáři depicts a "Fat Man" atomic bomb that should have been dropped on Kokura town, but the target has been changed to Nagasaki for a bad weather conditions (which is historically correct).

The image of the bomb itself is not so accurate. What interests me is the triangular symbol on the bomb. I can't find its meaning anywhere. Is the symbol purely fictitious or does it have any meaning?

    An answer could establish that it has meaning, but no answer can establish that it has no meaning. – Aaron Brick May 23 '17 at 1:39
  • Okay I will put it in Movies community - I just hope they won't say it belongs to History community :( There is also much less probability someone will know an answer there... and I searched through all communities and have not found better one. – Libor May 25 '17 at 14:35

The bomb depicted is of the "Little Boy" type, not the "Fat Man" type. (Note the elongated form -- "Fat Man" was more rounded.) So we're looking at the Hiroshima bomb, not the Nagasaki one. (Quite a slipup by the movie producers...)

This is a picture of "Little Boy" directly prior to being loaded into Enola Gay. There are no such markings on the bomb, indeed there are various differences (external fastenings, cables, bolts etc.) between what was loaded into Enola Gay and what is pictured in the question.

So, while the symbol might have a meaning somewhere, it has none with regards to "Little Boy", because it was not on "Little Boy".

  • I know the shape of the bomb is incorrect but the movie was about Kokura/Nagasaki, so I came from that. Anyway, that's irrelevant - I care just about the symbol. – Libor May 24 '17 at 11:24
