This just came up in my YouTube feed youtu.be/P4DThUr7bsY something I had not heard of.

I feel that it may be of interest to some here and would like to know if anybody knows more of it.

I thought it was diverted into the Tetsujin-28 go project, but that also had to wait until after the Pacific War. At least according to the 193 manga. Just kidding.

Yes. The only real secret.

Always forgotten, but now confirmed.

It was feasible and therefore worth pursuing. That was essential knowledge by all accounts. There was huge doubt at the time amongst physicists world wide.

There were two concurrent atomic bomb programs in Japan. One by the Army and one by the Navy. The two services were so much at odds with one another that they never merged into a single effort.

Japan did have some excellent physicists working on the project but it was doomed to failure because they lacked the resources. American bombing made it nearly impossible to conduct a program.

All the major belligerent powers had a bomb program. But none had the resources to pull it off except for the United States, which spent enormous resources and treasure. The Manhattan Project took years to develop the first nuclear weapons. No other nation except the United States could develop a weapon in time to be used during the war.

I still say that the physics was very much questioned at the time. A critical mass had been confirmed (was that Chicago?) but an explosive yield remained very theoretical. That was the real secret…..

It could work. Heavy water makes for good Kirk Douglas movies, true heroism (very like the film actually) or 633 Squadron, but was a dead end. You needed a source of Uranium or Plutonium, easiest found in not-German-occupied Africa
