Drawing uncovered of 'Nazi Nuke' 639

ninjee writes "Historians working in Germany and the US claim to have found a 60-year-old diagram showing a Nazi nuclear bomb. It is the only known drawing of a "nuke" made by Nazi experts and appears in a report held by a private archive. The researchers who brought it to light say the drawing is a rough schematic and does not imply the Nazis built, or were close to building, an atomic bomb. But a detail in the report hints some Nazi scientists may have been closer to that goal than was previously believed. The report containing the diagram is undated, but the researchers claim the evidence points to it being produced immediately after the end of the war in Europe. It deals with the work of German nuclear scientists during the war and lacks a title page, so there is no evidence of who composed it. One historian behind the discovery, Rainer Karlsch, caused a storm of controversy earlier this year when he claimed to have uncovered evidence the Nazis successfully tested a primitive nuclear device in the last days of WWII. A number of historians rejected the claim. The drawing is published in an article written for Physics World magazine by Karlsch and Mark Walker, professor of history at Union College in Schenectady, US."

    First, if you look at the diagram [], you'll see that it plainly shows a plutonium core. Problem, Nazi Germany did not have an operational nuclear reactor. Thus they had no ability to create kilograms of plutonium. This makes the diagram a pipe-dream at best.

    Second, if you look at the diagram you'll see that it is initiated a gun-type trigger, something that is impossible for Pu. This makes the diagram look like the work of someone that doesn't know what they are doing. Maybe this was deliberate (though rather obvious) misinformation by a scientist who didn't want Hitler to get the bomb.

    Third, it is undated, and unnamed, from an unknown source. Not worth even reading.

    In any event, Germany had no means of effectively delivering such a weapon. They lacked the heavy aircraft which the USA used. The V2 rocket only had a fraction of the payload capacity needed. The best they could have done is load it on a cargo vessel and attempt to sail into someone's harbour. Or leave it behind in a city like Paris after retreating. Neither of which would have been terribly impressive, since they would be ground-bursts and not much different from a few tons of dynamite.

        dirty bombs are completly ineffective though. the us military has looked into their use. the radiation from one is confined to too small an area. ensuring, with a large enough explosion that a larger area is covered just lessens the amount of radioactive material in a given area, lessening the effect. either way it is a simple cleanup operation.

        Nobody knew about those properties of radioactive materials in WWII. That is one of the reasons the US decided to use nuclear bombs on Japan. You have to remember that bombing was amazingly imprecise back then. If you wanted to take out military bases and industrial production in a city you pretty much leveled the city trying to do so. Bombing strategy was to drop a whole mess of bombs in the general area (we are talking like quare mile here) of your target. By chance some of them would hit it.

        So the appeal of the atomic bomb wasn't it's additonal features, those were unknown. It was just thought to be a really big bomb. Rather than needing to send hundreds of bombers and dropping tens of thousands of bombs, you could send in just one bomber and drop one bomb. You'd risk a lot less assets, eliminate targets much faster, and save lives (yours at least) and money.

        You also have to remember that, even had it been known what a direty bomb was, nobody would have been impressed. For one thing direty bombs are pretty fucking worthless militarily. Most radio active elements, but particularly the ones we are tlaking about here (uraunium and plutonium) are very, very heavy materials. This means their airborne time is very low. Well if you just spread them around, you really aren't going to cause a lot of effect. They need to get inside people to do real damage, or people need prolonged exposure. Just being externally exposed to a little uranium lying somewhere near you won't do much.

        Also you have to remember this was a very, very dirty war. It was pretty much no holds barred. Gas attacks of various kinds, of example, were used. Civilians died all the time just due to the nature of war. As I said, you'd take out an entire city to try and take out it's infastructure. So if you managed to make a few hundred people sick with radation poisining, oh well, big deal, people were dying all the time from the war.

      Agreed, it looks more like someone's fantasy about what a 1940s era atomic weapon should look like than a real one.

      Is it possible it was a design "speculated" from spy reports from the allies? It does capture two crucial design decisions (gun assembly and plutonium core), but manages to mix them up in a single entity. Which would be an easy mistake to make if one was relying on shaky intelligence from someone close to the Manhattan project, but not too close.

      The design still looks approximated though, and does not take into account the scale or space requirements of a v2-type rocket.

      Germany invested a lot in rocketry research, and the V2 wasn't the only thing the had designed.

      Ballistic missiles are known by everyone because of the cold war hype, but with that era's technology and bearing in mind that they didn't need to go all the way to america with it, a cruise missile is where it's at. I.e., a rocket with wings. You don't have to launch the thing upwards with a rocket to hit Britain from France, you can just as well launch it horizontally or on a flat arc and use wings to provide the needed lift. Like the V-1 did, for example.

      And they did research and build just that too: rockets with wings.

      The Me-163 Komet for example was an interceptor aircraft with a liquid-fuel rocket (not turbojet) engine. It reached a speed of approximately 600 mph (almost 1000 km/h) and had a maximum range of about 80 km.

      Nasty thing and more dangerous for the pilot than for the enemy, but to chuck a small bomb without a pilot across the channel it would have worked outstandingly.

      And I have no doubt that, if they absolutely needed to chuck a 4 ton bomb (the weight of the hiroshima bomb), they could have slapped 2, 3 or 4 of those engines on an airframe with bigger wings.

      It's a lot easier to design such a one-shot contraption, when you don't have to worry about being able to land safely, or about structural damage during flight. It can, for all you care, come apart at the end, as long as it does it on the other side of the channel.

They still find unexploded bombs now and then, all over the city, and people still die from exploding bombs, like a few months ago, where one bomb exploded after building workers accidently hit it with an excavator, who were killed by that. And they had to barricade a huge area around that, because they found another unexploded bomb and feared the 144 hour timer could have been activated by the first explosion.

    He claims to have stopped the scientists from developing the bomb any further - not because he was opposed to the concept if such a weapon (he certainly wasn't). The reason was that it was clear it would need much more time than was available in order to complete the work.

    What was considered feasible was the idea of an "energy producing Uranium motor" for use in vehicles, and research was switched in that direction around 1944.

    Antony Beevor's excellent book on the fall of Berlin also makes it clear that the Germans' nuclear research facilities were well known to the Russian's and were a major influence on Stalin's tactical decisions regarding Berlin. He was determined to obtain the fruits of this research.

    The book also makes clear that Heisenburg did not try to sabotage the programme but was eager to succeed. This view is also backed up by the famous meeting between Heisenburg and Nils Bohr in Copenhagen in 1941 and Hesinburg's views at that time.

      Yes we do. In a major war, losing is really, really bad. So you have an all out push to gain any advantage you can. People volunteer for, and can be directed into projects they otherwise might not have pursued. And given a blank check to get it done.

      No war? You can take your time on things. Writing papers, doing endless experiments to get it 'just right'.

    It may be too difficult to read given the poor-quality reproduction on the BBC article, but if possible could somebody translate the labels on that diagram?

    From what I can tell, it looks to be a straightforward version of the "gun design" used in the Hiroshima bomb, which a) is so obvious that I think even I could have figured out the basic concept, and b) won't work with real plutonium as Pu-240 contamination will cause the weapon to blow itself to bits before enough of the plutonium has fissioned. So, even if it was true, they had a very long way to go before they could have made a bomb.

    An implosion design, by contrast, would be a much bigger deal, though as I understand it just having the idea is a very long way from making it work.

    Two final things: one of the reasons why the Nazis never got very far on their nuclear weapons project is that they could never get a reactor working; one of the key reasons for that was their supply of heavy water was kept from them by Norwegian partisans working with British SOE. Their story is a pretty amazing one [].

    And finally, while it's not possible to make a plutonium gun bomb now; it should be possible in the very distant future. Pu-240 (the contaminant) has a much shorter half-life (about 6500 years) than Pu-239 (about 24,100 years). So, over (lots of) time, the proportion of the Pu-240 should gradually reduce. So maybe these Germans were just a little ahead of their time...

  • I'm currently reading Karlsch's latest book "Hitlers Bombe" which unfortunately has not been tranlated in English yet.Anyway in this book he's done very good work demonstrating that the Germans were VERY actively conducting nuclear research during the war.They even had a comittee working on the concept of nuclear weapons before the U.S had the faintest idea of what they were about (early 1939).What the germans did wrong was that instead of building a giant research/production complex (like the US did with

    If you look at the diagram on this page [], there seems to be what looks like a date on the upper right side. It seems to say "Halteose fur AS/12/44". Any ideas what that means?

    Also, the associated article states that the bomb appears to be a hybrid fission/fusion device, which was far more advanced than the two fission-only devices used on Japan.

    • Accoring to the Systran widget for Dashboard (God bless you and your widgets, Dashboard!) it means "Retaining eye". I guess it's a an eye for a hook of some kind.
    • A "Halteoese" ("oe" instead of German diaresis on the "o") is simply a "holding ring", and since the bomb is supposed to fall to earth on a parachute, the AS/12/44 probably stands for "AbwurfSchirm" or drop parachute.

      The date is probably the mark of the parachute type. Nothing more.
    • The fission/fusion device is actually a separate design (and was supposedly tested, according to the article). If true, there was some advanced thinking going on, but they clearly didn't have a workable full-scale nuclear weapon of any kind.

    My physics professor at the University of Nevada Reno, the late Samuel Goudsmit (best known as co-discoverer of the electron's spin), was technical lead on the ALSOS project [] immediately after World War II. His team went into Berlin and certain other areas shortly after the Allies captured them, in order to sieze any Nazi nuclear material and atom bomb research. They found lots of stuff, then spent a few months studying it closely.

    As described in the Wikipedia article (and in Goudsmit's 1947 book, ALSOS: The failure of German science), the Germans never got even remotely close to developing an A-bomb. Their approach to the physics was fundamentally mistaken and would never have led to anything workable. Good news for civilization, bad news for alternate-history writers and sensationalist journalists, but in any case conclusively settled. Goudsmit was a smart guy and knew his stuff.
