      @wellerstein (Some of the numbers have additional caveats attached to them but they are good for order of magnitude estimates)

      @wellerstein does the German "total" include the Norwegian stock sunk by commandos? If not, how much larger including that ?

      @n1vux I didn't include the Norsk Hydro water. That comes out to be about 500 kg of very variable quality stock (a lot was only ~1% D2O).

      @wellerstein so even including it, qualitative comparison would be unaffected. loss put them further behind, too far. thanks.

      @n1vux Right. Either way they were very far from enough to make a reactor the size of CP-3, much less a Pu-production reactor.

      @n1vux (Which I hesitate to add was a pretty accurate assessment. The Manhattan Project is the anomaly in WWII — only "real" nuke program.)

      @wellerstein US/UK funded several massive developments in parallel, incl Crypto, Radar. Even did both U and Pu designs.

      @n1vux My general point is that bomb work turned out to be very difficult, barely do-able within timetable of war even with massive effort.

          @wellerstein yes. (As were the several rotor cipher breaks.) The best surprise weapons are "impossible".
