Nazi Atomic Bomb projects

After World War 2 it came to light from personal memoirs and collections of papers, which were not seized by the Allies, that Nazi scientists Dr Erich Schumann and Dr Walter Trinks filed up to 40 workable patent applications in wartime Germany from 1941-1944 for what we nowadays term tactical-nuclear weapons. 

Further light was given in post war articles by, or interviews with Dr Kurt Diebner and Dr Walter Trinks. Their wartime designs were amazingly credible. They were far more sophisticated than the Allied bombs dropped on Hiroshima and Nagasaki requiring only sub-critical quantities of fissile material. Their designs were also adopted post war by the Americans in the so called Swan Device of 1956.

Their minature nuclear weapon designs were inspiration for the American Swan Device of 1956. Diebner was hired by Operation Paperclip and went to USA to guide the US nuclear program, working closely with Dr Freidwart Winterberg. Trinks went to France after WW2 helping to develop their nuclear weapons program.

Corroboration by Stockholm Signal:
Corroboration emerges from various directions. For example the so called Stockholm signal. An enciphered diplomatic signal from Japan's embassy in Stockholm back to Tokyo sent in five parts in December 1944. It reported Germany's Uranium atom splitting weapon with an explosive of tremendous force. The ULTRA decrypt of this signal gathered dust in US military archives until 1978 when it was declassified. There is currently no explanation reconciling the contents of that signal with the conventional view that Germany never had nuclear weapons. [1]

Text Box

Part 1

This bomb is revolutionary in its results, and will completely upset all ordinary precepts of warfare hitherto established. I am sending you, in one group, all those reports on what is called the atom-splitting bomb. It is a fact that in June of 1943, the German Army tried out an utterly new type of weapon against the Russians at a location 150 kilometers southeast of Kursk. Although it was the entire 19th Infantry Regiment of the Russians which was thus attacked, only a few bombs (each round up to 5 kilograms) sufficed to utterly wipe them out to the last man.

Part 2

The following is according to a statement by Lieutenant-Colonel UE [ISHIWARA] KENJI, advisor to the attaché in Hungary and formerly in this country, who by chance saw the actual scene immediately after the above took place:

"All the men and the horses the explosion of the shells were    charred black and even their ammunition had all been detonated."

Moreover, it is a fact that the same type of war material was tried out in the Crimea, too. At that time the Russians claimed that this was poison-gas, and protested that if Germany were ever again to use it, Russia, too, would use poison-gas.

Part 3

There is also the fact that recently in London - in the period between October and the 15th of November - the loss of life and the damage to business buildings through fires of unknown origin was great. It is clear, judging especially by the articles about a new weapon of this type, which have appeared from time to time recently in British and American magazines - that even our enemy has already begun to study this type. To generalize on the basis of all these reports: I am convinced that the most important technical advance in the present great war is in the realization of the atom-splitting bomb. Therefore, the central authorities are planning, through research on this type of weapon, to speed up the matter of rendering the weapon practical. And for my part, I am convinced of the necessity for taking urgent steps to effect this end.

Part 4

The following are the facts I have learned regarding its technical data:

Recently the British authorities warned their people of the possibility that they might undergo attacks by German atom-splitting bombs. The American military authorities have likewise warned that the American east coast might be the area chosen for a blind attack by some sort of flying bomb. It was called the German V-3. To be specific, this device is based on the principle of the explosion of the nuclei of the atoms in heavy hydrogen derived from heavy water. (Germany has a large plant in the vicinity of Rjukan, Norway, which has from time to time been bombed by English planes.). Naturally, there have been plenty of examples even before this of successful attempts at smashing individual atoms. However, as far as the demonstration of any practical results is concerned, they seem not to have been able to split large numbers of atoms in a single group. That is, they require for the splitting of each single atom a force that will disintegrate the electron orbit.

Part 5.

as far as the demonstration of any practical results is concerned, they seem not to have been able to split large numbers of atoms in a single group. That is, they require for the splitting of each single atom a force that will disintegrate the electron orbit. On the other hand, the stuff that the Germans are using has, apparently, a very much greater specific gravity than anything heretofore used. In this connection, allusions have been made to SIRIUS and stars of the "White Dwarf" group. (Their specific gravity is 1 thousand, and the weight of one cubic inch is 1 ton.) In general, atoms cannot be compressed into the nuclear density. However, the terrific pressures and extremes of temperature in the "White Dwarfs" cause the bursting of the atoms; and

Part 6

There are, moreover, radiations from the exterior of these stars composed of what is left of the atoms which are only the nuclei, very small in volume. According to the English newspaper accounts, the German atom- splitting device is the NEUMAN disintegrator. Enormous energy is directed into the central part of the atom and this generates at atomic pressure of several tons of thousands of tons (sic) per square inch. This device can split the relatively unstable atoms of such elements as uranium. Moreover, it brings into being a store of explosive atomic energy. A-GENSHI HAKAI DAN. That is, a bomb deriving its force from the release of atomic energy.


General Claims:
Until 2005 few people seriously questioned the accepted historical account that Nazi Germany failed to produce an Atomic Bomb, but with the publishing of Hitler's Bombe, (2005), by author Rainer Karlsh, this accepted account of history is now widely challenged.

Karlsh astonished the world when he revealed evidence from various witnesses of a nuclear test on the Baltic Island of Rugen in October 1944, including press correspondent Luigi Romersa who only passed away in 2007.

Karlsch claimed these tests in October 1944 were followed by two more nuclear tests at Ohrdruf Concentration Camp in March 1945. He produced Kremlin archives to prove that Soviet intelligence reported the Ohrdruf tests to Stalin.   Karlsh also produced the account of then still living witness Claere Werner custodian in 1945 of Wachtel Castle near Arnstadt, whose interview is available on Youtube.[2]

A 1943 OSS report found in the Woods Memorandum to US secretary of State Cordell Hull also refers to a series of nuclear tests in the Schwabian Alps near Bisingen in July 1943. These tests are corroborated by seismic records.

Nature of the Nazi Weapon

The weapons allegedly weighed 4-5 kilograms and used the principle of crushing Lithium into Deuterium at huge pressures & temperatures to generate fast neutron X-rays, known as a plasma pinch. Ironically this method was also known to the Manhattan Project in 1942 when the exiled scientist Enrico Fermi tried to persuade the Americans to develop this concept. The Manhattan Committee rejected a minaturised nuclear warhead with plasma pinch technology as too technologically challenging. 

These plasma pinch X-rays caused a fusion reaction between molten Lithium from the hollow charge liners and Deuteride coating the fissile target. The neutron flux was high enough that it created uniform criticality throughout the whole fissile mass, thus ignited fission in small, sub critical quantities of bomb grade Uranium. The fissile target is understood to have been a mere 150 grams of Uranium 233. This method avoided the need for a massive Uranium 235 enrichment project. The quantity of fissile material required were much more modest than the enriched material required for Allied nuclear weapons and in turn demanded a project much smaller than Oak Ridge for harvesting fissile material.

$64,000 Question...

Why if the Nazis had nuclear weapons, did they still lose the war?

The most logical explanation appears to be Churchill's threat to drop Anthrax laced cattle cakes over Germany in August 1944. Germany had no antibiotics and would have faced starvation within 2 weeks had Anthrax been used. Even earlier than this however USA at the beginning of July 1944 threatened Hitler through the German Legation in Lisbon that unless he sued for peace within 6 weeks Dresden would face attack with a nuclear bomb. In the light of continuing efforts by the United States to keep references to these  matters classified, or suppressed, Nazi acquisition of nuclear weapons cannot simply be dismissed out of hand.

Frustrated nuclear attack on New York?

There does however appear to have been at least one attempt to attack USA with nuclear weapons when a lone six engined Junkers aircraft was downed in shallow coastal waters south of Owl's Head, Maine about 17-18 September 1944. The bodies of three German aviators were recovered nearby on 28 September 1944 and were taken to the Rockport Coast Guard Station. It appears they were buried nearby with a small stone cairn erected over their grave. Locals were warned by FBI and Secret service never to repeat their sighting to anyone, thus this pivotal attack on USA has gone unnoticed in all of 65 years. Could it be that the failure of Hitler's Last Trump arose not from a failure to build a nuclear weapon, but from the inability to deliver the weapon over it's prime target, New York?

This is a chart of New York prepared for Goering in 1943 describing the effects of a nuclear air burst over the city. Bombing New York was a major obsession for Hitler. English text has been added over the chart by a more modern author:


Another justification for nuclear secrecy was raised in the so called Monsanto Report to A.H. Compton, where the authors comment on the ethicacy of releasing "useful information" in their report and Nazi records.[3]

Authors note that, "...anyone knowing what is in the German reports can establish a chain reaction provided he has sufficient material.

If that statement is correct then anyone with a truly enquiring mind should be curious to know why the Nazis did not succeed in the race for the Bomb, nor indeed why they lost World War Two.

My Personal Commentary

In the Postwar era the free press and more lately the internet has helped us to understand that Governments do lie to us and that history books can't be relied upon. Is there some other explanation how World War Two came to an end?

Those not interested need read no further, and relief is just a click away because the internet is full of conventional accounts of history to occupy their time. Perusal of my website is entirely optional.

As this website takes shape, I intend to add successive webpages to enlighten readers to the latest and in many case most controversial information coming to light about the the real Nazi Atomic weapons project.
