Okay, a few questions for Mr. Gunson after reading through most of this thread.
First, you say definitively that the Schumann-Trinks boosted fission U233-lithium deuteride bomb was successfully tested once or twice. I think you
wrote that this was at either or both of the 1944 detonations (Bug Island), and not the 1945 event (Ohrdurf). Karlsch and his American research
associate, Professor Mark Walker of Union College, say that the 1945 test was of another design, a "hybrid" fusion-fission bomb designed by the
Diebner group. The rough schematic included in their co-authored article "New Light on Hitler's Bomb", which appeared in the online magazine
on 1 June 2005, definitely does not appear to my eyes to be the Schumann-Trinks bomb.
Question: do you have documentation that proves that either or both of the 1944 tests were successful detonations of the S-T boosted fission bomb
design? If either or both of these tests were not the S-T bomb, what were they, and can you document what they were?
Here is a link to the Physics World webpage that leads to the "New Light on Hitler's Bomb" article. You have to create a username to view the article
but that is easily done.
Second, I have not previously heard of the Oslo Report or of the debrief by the Norwegian in which he mentioned the Japanese atomic bomb project(s)
and German assistance to them. Is the debrief the same thing as the Oslo Report or are these separate documents? And can you post them or tell me
where you found them?
Third, and most important, can you document how and where the Germans produced enough fissile material, whether U233 or U235, for one or more atomic
bombs of whatever design or configuration? You have mentioned Paul Harteck's centrifuges and we know that some were built, but what I am told to this
point by sources I consider to be reliable is that this was essentially a pilot program and that fewer than 50 and probably more like 25 or 30 of
Harteck's machines were built---far too few to have produced enough U235, at any rate, though U233 is another matter and can be produced by other
means. But again: absent a working breeder reactor, or one that worked well enough long enough to enable the Germans to pursue a P239 or "element 94"
route to a bomb, that leaves U235 and/or U233. How and where and how much U235 and/or U233 was produced by the Germans? You have mentioned I G
Farben and I have no doubt that that corporation was up to its eyeballs in all of this, but I am asking for specific information about production, if
you have it. Obviously the Germans had considerable resources in terms of uranium in some form, otherwise they would never have tried repeatedly to
send it to Japan. At least some German uranium did get through to Japan, per the testimony of a WWII Japanese Army officer in, I think, 1985. (His
name escapes me at the moment.) I think he said 2000KG of uranium 238 oxide arrived in Japan---a considerable amount, and presumably more of it was
sunk in various German and Japanese submarines en route. How much? (However, the proportion of U235 in even 2000KG of U238 oxide would be very small
and even when separated and highly enriched might not be enough for a bomb. Assuming from what I have read that the proportion of U235 in naturally
occurring U238 is about 0.7%, if it could be separated efficiently you would end up with about 31 pounds of U235---about half of what you need for a
single, "natural" critical mass but not necessarily half of what you would need for a crude gun-type bomb. The Little Boy weapon had the equivalent
of nearly three (3) natural critical masses of 80-85% U235, or somewhere between 160 and 200 pounds of HEU, because the limits of American engineering
meant they needed that much for the bomb to go off. If the Japanese were similarly limited, then 31 pounds of U235 would have been about a sixth or
so of what they needed. Well on the way but not there. This sort of calculus and resultant production difficulty is why I wonder if they didn't
switch over to Heisenberg's thorium-to-U233 idea late in the war.)
Fourth, the book Hitler und die Bombe
contains claims by a WWII German official or scientist that the Germans completed 15 nuclear weapons of
some kind. Do you know what kind of weapons these allegedly were? Fission bombs, boosted fission, dirty bombs, or a mixture? Do you have any
documentation for this claim other than the German's say-so? Who was this German and how well-placed was he in any of the German a-bomb projects to
know anything for sure? How believable / reliable is his testimony?
I think you are doing great spadework here and I am sympathetic to your thesis and would like to see how much documentation there is that
demonstrates, if not proves, greater-than-expected Axis progress toward working atomic weapons, or perhaps even their successful development of those
weapons. To my mind you have already done a great service.
BTW, regarding your comment that, at the outset of the war, the Allies wanted to set Germany and the USSR against one another, that is certainly true
of Churchill. But there is a great deal of evidence that this was NOT true of FDR, who as a committed Keynesian socialist and anti-colonialist was
very definitely sympatico with Stalin, whether he or the rest of the American left admitted this publicly or not. Our friend Robert Wilcox has been
digging around in this area of US history and has found some highly incriminating information about significant penetration of the US federal
government before and during WWII by Soviet moles and sympathizers. FDR would of course go on to give half the world to Stalin at Yalta, totally
inexcusable to my mind even if we acknowledge Roosevelt's terrible physical condition and impending death by the time he got to Yalta.
