    No hint, it was full on sarcasm!

    Makes me wonder if what is going on in your garden shed is not just limited to creating nice miniature military models.

    Hey! I resemble that remark! I don't have any uranium or plutomium that the government knows about and it is going to stay that way unless they raise my taxes!

There's no evidence either way whether it would of course but it's quite conceivable that the pooled intellectual resources would figure it out given Britain's lead in the theoretical side. The real problem as far as I can tell is how quickly they can design a working bomb given the pressure on resources. I'm assuming an Anglo-German Non-Aggression Pact which allows for a degree of cooperation. I'm also assuming US Lend-Lease being granted to the Soviets meaning that the Mannheim Project has to come to fruition by late 1944 or risk being shut down to cover more pressing needs.

    Assuming that Alien Space Bats and Gerry Anderson's puppets don't intervene to tip the balance in favour of one side or the other it's my belief that the combined resources of the Anglo-German teams, bolstered by a functioning Western European economic system, would be sufficient given enough time. Whether enough time would have been available is questionable. Assuming a weapon of some sort could have been constructed by late 1944 how would it have been used? If two or three warheads/bombs of, say, 3000 lbs were placed at the disposal of the Nazis what would have been the targets and how would they have been delivered? What effect would their use have had on the course of the war?

    Note: I'm not saying this was even vaguely likely but it's worth asking.

    Maybe, but that's not the show that featured that tagline!

    Whether heavy water makes a bomb or not is immaterial. The Germans were making it for use in their atomic programme at a Norwegian hydro-electric plant. The power generated by the plant might be enough to satisfy the needs you describe .... assuming a bit of typical British ingenuity combined with German engineering excellence.
    There is the minor problem of enriching the fuel, which really is the problem, no matter what technology route you take. Natural uranium contains about 0.7% U-235. Not enough to to maintain a critical mass. The expensive and energy hungry bit is building the uranium enrichment to get it up to 3-5% U-235 for reactors, and 84% or more for a bomb. You're going to have to invest in a lot of gas and thermal diffusion technology. And you'll need an expert in organofluorine chemistry because UF6 is highly corrosive. There goes another year of research...

    The problem is that the German heavy water reactor design is crap. They would have had to completely redesign it to get it to work. Using the "necklaces" of blocks of randomly oriented raw uranium would not have worked. They needed to arrange things far more precisely and that called for control rods and a fixed fuel geometry. The graphite route the US (Fermi) took was much simpler even if far more messy.

    The only way I can see for the German reactor to be controlled is to pull the core from the water. They couldn't have used a neutron poison like boron as an alternate as this would have contaminated the water and been hard to remove later.
    Pulling the core when it is operating is not a smart thing at all. Between the heat and radiation you are looking at a likely disaster if you do.

    So, the Germans have to start from scratch after their first attempt fails.
