(22,000 posts)Hiroshima was an alternative target because the primary was to socked in with clouds. I'd have to go look in a book to refresh my memory on what the primary was for that mission. The city of Hiroshima had factories that were integral to the Japanese war effort.
I tend to disagree with you on whether we fully understood the power. Given that a test had been conducted in NM, I think we had a good idea the bomb was going to cause massive damage.
When the crew (of the Enola Gay) took off, only a handful actually knew what the bomb was (I believe if memory serves me right besides Tibbets, and Parsons and his assistant knew for sure. There may have been others). Other crew members on the plane had some idea, but didn't know until Tibbets announced it once they were airborne.
I've read and studied about the bombings quite a bit over the years.
