At the end of WWII, were nazis working on anything else besides V-2? If so, what was it, how close was it to completion, and could it potentially turn the events around for them?

The Nazi were working on an atomic bomb. That would have changed the course of the war if they could have made enough of them. –  Sardathrion Apr 23 '12 at 9:40
    
Yeah, that's the kind of info I would like to know, just with details :) Thanks! –  Eugene Apr 23 '12 at 10:04
    
The last experiments for the German atomic bomb where in Haigerloch. There as a little museum about it. –  knut Apr 23 '12 at 10:14
    
Unfortunately, I don't speak German. So if you could translate it, provide some background info, it could make a great answer! –  Eugene Apr 23 '12 at 10:18

Your knowledge of WW2 is abysmally incorrect. the last Luftwaffe reconnaissance flight over England was 10th April 1945 by an Arado 234. Evidence used by the British to indict Maj General Dornberger for war crimes at Nuremberg are available in PRO file WO.208/4178, GRGG 341 report of secretly recorded conversations by Dornberger in captivity in his discussions with fellow German Generals. Dornberger discussed the V-2 was to be fitted with the Schumann Trinks designed 1 kiloton tactical nuclear weapon. Had they been used, would have carpeted London with nuclear blasts. Duh you know nothing –  user2357 Jul 22 at 2:22

Wunderwaffe (literally, wonder weapons) - absolutely, they had many, many designs under way.

http://en.wikipedia.org/wiki/Wunderwaffe

They were working on the A9/A10 (think of a V3 rocket), that would be a multi-stage ICBM that would be able to hit the US, although it wasn't likely to be very accurate. This was planned to be available from 1946.

http://en.wikipedia.org/wiki/Aggregate_series#A9

The Nazi's had already tested firing V2s from submarines, the plan here was to allow them to launch at the mainland US from U-boats just off the coast of the US. They had actually manufactured three of the required launchers to do this and had conducted extensive tests by the end of the war.

http://www.prinzeugen.com/V2.htm

No doubt you have already heard about the Amerika Bomber, there were several candidates under various stages of development. Hitler had a fascination with bombers and so this was one area of development that got a lot of funding, at the expense of other, arguably more important schemes:

http://en.wikipedia.org/wiki/Amerika_Bomber

There were several "super heavy tank" designs being planned, with the Maus being most advanced, they actually had built two prototypes of this by the end of the war.

http://en.wikipedia.org/wiki/Panzer_VIII_Maus

However, the Maus is nothing compared to these behemoths!

http://en.wikipedia.org/wiki/Landkreuzer_P._1000_Ratte

http://en.wikipedia.org/wiki/Landkreuzer_P._1500_Monster

The above were only at the fairly early stages of planning.

There were plans for a super-heavy battleship, the H Class that would be around 140,000 tons with 20 inch guns that would dwarf the Yamato, two keels were laid down but soon scrapped.

There were many other plans, guided missiles, super-guns, helicopters to name a few, it's a very interesting subject with plenty of information on the internet.

There are other more conspiracy theory types of weapons that I won't go into here, but if you search for Hitlers Bell (Die Glocke) you'll find one example.

the towed Lafferentz capsules which I think you refer to were imaginative but relatively impractical. They consumed all of the fuel of a long range type IX-D2 U-boat in a one way voyage to the American Atlantic seaboard. One 500 ton capsule was tested in trials with U-1062 (IIRC) and was never found after the war whilst three improved 800 ton capsules were found at the Vulcan Stettner shipyards by the Soviets. these became the basis for all modern ballistic missile submarines. The biggest drawback was decomposition of hydrogen peroxide required to drive V-2 fuel turbopumps. –  user2357 Jun 18 at 23:21

German physicist tried to build an atomic bomb, at least there were experiments.

At end of WW2 there was a laboratory in Haigerloch. It is told, that American scientist checked everything and took the Uranium (and the German scientists) to the US. If the German scientists really tried to build an atomic bomb is not really clear.

More can be found in Physics Today - Volume 53, Issue 7, Page 34. "The German Uranium Project"


Another (more popular) article. I added a rough translation.

Stern magazine: Der Atomkeller von Haigerloch (Sorry German)

In britischer Gefangenschaft können es die Wissenschaftler später kaum fassen, als sie am Abend des 6. August von der US-Zündung einer Atombombe über der japanischen Stadt Hiroshima hören.

The German scientiste were astonished, when the heard about the exposion of the US-bomb in Hiroshima

Die Forscher um Heisenberg behaupteten nur eine "Uran-Kraftmaschine" entwickeln zu wollen. "Die Atombombe stand nicht auf dem Programm", betonte der beteiligte Wirtz nach dem Krieg. Neuere Forschungen ergaben jedoch Hinweise auf eine vorhandene gezielte deutsche Atombombenforschung.

The sientist say, they only wanted to build a "power machine". But newer researches give an indication of plans to build atomic bomb.

Great, thanks for the info! Extra plus is a non-Wikipedia source, but I can only +1 once :) –  Eugene Apr 23 '12 at 10:24
    
I'd read elsewhere that the captured records at the end of the war stated that the Germans had worked on it for a while, decided it was impossible, and had quit. Wish I could find that reference. –  T.E.D. Apr 23 '12 at 14:37
    
The German's were well ahead of the US in the development of an atomic weapon in the late 1930's but due to cutbacks in research they fell behind. Germany cut back on a lot of research projects around 1940 as the war was going so well only to begin re-investing when things started to go badly around the 1942/1943. Lucky for us they did scale back research for at least a couple of years! yourdiscovery.com/web/world-war-2/ww2-focus/flashpoints/… –  davidjwest Apr 23 '12 at 21:00
    
@davidjwest: The Nazis lost the atomic race when they chased away Einstein, who started the U.S. atomic effort instead. They would have gotten the atomic bomb if he had been working on a GERMAN bomb. See my answer below. –  Tom Au Mar 9 '13 at 17:19

@TomAu - My understanding was that Einstein's main contribution to the building of the A-bombs was convincing the US Government to create them. He didn't actually work on them. However, a lot of physicists did, and there were certianly German and Eastern European refugees among them. So the point is a good one, if you expand it to scientists in general. –  T.E.D. Mar 11 '13 at 16:10

The nearest and biggest threat to the allies, had it made it into combat, was the Horten Ho-229 flying wing fighter, and the 6 engine heavy bomber that was being designed for bombing campaigns against the American east coast.
http://en.wikipedia.org/wiki/Horten_Ho_229
Had it made it into production in numbers, it could have changed the balance of power in the air. Of course on its own it would likely not have changed the outcome of the war, it was far too late for that.

Given that German jet engines typically had a TBO life of just 25 hours it is hard to imagine how a six engine Gotha bomber could count on all six engines to work for the entire flight? –  user2357 Jun 18 at 23:53
    
@user2357 that was a problem more with the manufacturing than the design. As we're in the realm of speculation as to what might have been, we can speculate they could have manufactured higher quality goods as well. –  jwenting yesterday

The Germans were working on an atomic bomb. But the effort was stymied for a couple reaons.

  1. The effort was led by Werner Heisenberg (of the Heisenberg uncertainty principle), who had a less-than-perfect understanding of atomic physics. (And the Nazis had chased away the better, "Jewish" atomic scientists like Einstein and Fermi.) Some say that Heisenberg was a "bungler." But his defenders would say that he sabotaged the German atomic effort. For instance, he went to his former professor (Niels Bohr, a Danish Jew living in Copenhagen) for answers to his questions about atomic physics, and failed to get them. The Gestapo offered to torture the answers out of Bohr, but Heisenberg declined.

  2. The Germans had a shortage of "heavy water", most of which was produced in Norway. On one occasion, Allied agents planted a time bomb to blow up a ship transported a load of "heavy water" from Norway to Germany. Finally, Allied saboteurs blew up the producing Norwegian hydroelectric plant itself.

Actually, Fermi wasn't Jewish. But his WIFE was. And that was (bad) "enough" for the Nazis to have him ostracized in the European atomic world. –  Tom Au Mar 9 '13 at 17:21
    
Wow. Can you dig up links for any of this? I'd love to read more. –  T.E.D. Mar 11 '13 at 16:23

@T.E.D., Richard Rhodes wrote 2 books on the history of atomic weapons (The History of the Atomic Bomb, and Dark Sun) which go into more detail than you probably want. Heisenburg miscalculated the "mean free path" (the average distance a neutron can travel before colliding with a nucleus), and according to his calculations about all the U-235 in the world was needed to make a single atom bomb. Because of his status, no one would question his calculations. –  Tangurena Mar 11 '13 at 17:05

@T.E.D. Here's a link to wikipedia. en.wikipedia.org/wiki/Werner_Heisenberg. I remember seeing the "Niels Bohr" play about 20 years ago, and got it from there, not a book. Now you see why I believe that Heisenberg (a Nobel Prize winnter), "knew what he was doing." What he did't know, he didn't want to know. –  Tom Au Mar 11 '13 at 17:32

Heavy water is not H2O2 (this is Hydrogen peroxide) but H2O being the Hydrogen atoms an isotope (Deuterium) that has one proton and one neutron instead the usual hydrogen atom that onlye have one proton. –  Averroes Feb 12 at 9:48

It depends on what you see as a super-weapon.

In the fighter aircraft arena, by the end of the war Germany already had the Me 262 twin engine jet fighter and the Me 163 rocket powered fighter in service. It must be said that the Me 163 was not particularly effective.

The need to improve on the Me 163 led to development of the Me 263 rocket fighter, along with the Ju 248.

More advanced jet powered designs were built, including the Messerschmitt P.1101 variable sweep jet fighter, and the Focke-Wulf Ta 183 transonic fighter.

Another advanced desiagn was the Lippisch P.13a ramjet delta wing interceptor, which never got off the drawing board.

None of these reached production.

Nazi Germany developed tactical nuclear weapons as early as June 1942

This was detailed in a Magic decrypt held in NSA archives known as "Stockholm to Tokyo, No. 232.9 December 1944 (War Department), RG 457, declassified October 1, 1978. It was sent by the Japanese embassy in Stockholm decrypted on 12 December 1944. It refers to German development of a 5 kilogram nuclear warhead.

This signal states in part that:

The German atom-splitting device is the Neuman disintegrator. Enormous energy is directed into the central part of the atom and this generates an atomic pressure of several tens of thousands of tons 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.... That is, a bomb deriving its force from the release of atomic energy.

In another document prepared at the end of the war from interrogations of interned combatants by the US Naval Technical Mission Europe, cited as: “Investigations, Research, Developments and Practical Use of the German Atomic Bomb” dated 19 August 1945.

In that document there was an affidavit actually written by an interpreter Captain Helenes T Freiberger of the testimony given under interrogation by pilot observer Hauptman Hans Zinsser who said:

At the beginning of October 1944, I flew from Ludwigslust (south of Luebeck) [to] about 12 to 15 km from an atomic bomb test station, when I noticed a strong, bright illumination of the whole atmosphere, lasting about 2 seconds.

The clearly visible pressure wave escaped the approaching and following cloud formed by the explosion. This wave had a diameter of about 1 km when it became visible and the colour of the cloud changed frequently. It became dotted after a short period of darkness with all sorts of light spots, which were, in contrast to normal explosions, of a pale blue colour.

After about ten seconds the sharp outlines of the explosion disappeared, then the cloud began to take on a lighter colour, against the sky covered with a grey overcast. The diameter of the still visible pressure wave was at least 9000 metres (9km) while remaining visible for at least 15 seconds.

Personal observations of the colours of the explosion cloud found an almost blue-violet shade. During this manifestation reddish-coloured rims were to be seen, changing to a dirty-like shade in very rapid succession.

The combustion was lightly felt from my observation plane in the form of pulling and pushing. The appearance of atmospheric disturbance lasted about ten seconds, without perceivable climax.

About an hour later I started with an He-111 (aircraft) from the A/D at Ludwigslust and flew in an easterly direction. Shortly after the start I passed through almost complete overcast (between 3,000 and 4,000 meter altitude). A cloud shaped like a mushroom with turbulent billowing sections (at about 7,000 meter altitude) stood, without any seeming connections, over the spot where the explosion took place. Strong electrical disturbances and the impossibility to continue radio communication as by lightning, turned up.

Zinsser

There is further corroboration by a USN Intelligence report dated June 15, 1945 concerning "German Technology Transfer to Japan"

In Chapter 14 of that document it states this:

excerpt transfer of Atomic weapons to Japan

The German scientists behind this 5kg warhead were Haxel, Schumann & Trinks. What they developed was a method for detonating sub critical fissile mass by a process known as Fusion boosted Fission. It uses the plasma Pinch concept to ignite a mass of uranium far below the critical mass by using nuclear fusion to replicate the neutron flux required in a fissile mass at criticality.

Schumann Trinks warhead

In order to create fusion two opposing Hollow charges with conical Lithium liners were fired at a small mass of Uranium coated with Lithium-Deuteride plus a 2% contamination of Boron to slow down the reaction.

When conventional chemical explosive charges smashed the molten lithium liners into the Deuteride nuclear fusion occurred, expressing a vast nuclear flux. This worked like a spark plug to ignite the Uranium.

Maj General Dornberger leader of the V-2 project was interned in a special camp after the war for senior staff officers where all the rooms were bugged with hidden microphones. Transcript summaries of his conversations between 2-7 August 1945 were used in evidence at Nuremberg. Although heavily censored after the trials the report suggests Germany planned to use 5kg tactical nuclear weapons on the V-2 and also on the Rheinbote missile (mounted on an 88mm gun)

just as interesting, they describe a hollow pit design, which the US introduced into their weapons only several years after the war, mainly because of manufacturing problems. –  jwenting yesterday

During WW2 the Germans were also working on a transatlantic cruise missile using a mixture of coal dust, diesel and Acetone.

Lorin Ramjet tests early 1942

Tests were performed with such ramjet engines atop a Dornier 217 aircraft in France through the war.

Lorin ramjet

Trommsdorff-D-6000-Interkontinentalflugkörper was intended to launch from high altitude bombers such as the He-277 at altitudes of 46,000ft and 0.67 Mach. After launch they would climb to 80,000ft flying at 2.8 Mach much like the SR-71 cruise altitude. They would continue their flights to USA as robots similar in concept to the V-1.

According to a wartime report held on microfilm file at Maxwell AFB, Alabama, S.R.A.4394, the US 9th Army captured a working German Atomic bomb on 26 April 1945 near Goslar. The device known as 76-Zentner weighed 3.8 tons and the document notes it was flown back to the United States by Col Charles Lindbergh who in addition to being a qualified B-24 pilot was also a consultant to the US Navy Technical Mission Europe.

During 1945 Allied advances overran underground factories housing at least 60+ Anschutz Mark IIIB Uranium centrifuges each capable of enriching 250grams of Uranium by 7% per 24 hours. During each 12 day cycle these could produce 15kg of HEU enriched to 80% U235. At this rate Germany was capable during the second half of 1944 of producing enough HEU for one Hiroshima type bomb every 7 weeks.

unsourced conspiracy theories aren't viable answers. –  jwenting Jun 17 at 13:10
    
While this "information" is certainly unconventional, I disagree that it is a "conspiracy theory". The poster is citing facts, if you think the facts are fabricated, fine, downvote the answer. As long as the poster is citing (remotely) plausible facts, I think it qualifies as an answer. The "conspiracy theory" restriction, in my interpretation is aimed at people who spin up factless theories that are unverifiable. We want to error on the side of inclusiveness, even if sometimes it results in some kooky answers. –  Tyler Durden Jun 17 at 14:42

@T.E.D. No question about that, but he is citing theoretically verifiable facts. Also, it is an answer, not a question. Nowhere in the Help does it say you can't give wacky answers. If he were asking a question, sure, he would be held to a higher standard, but for an answer maybe he deserves the benefit of the doubt. –  Tyler Durden Jun 17 at 15:41
    
@TylerDurden - I didn't say it wasn't an answer. I'm just explaining why I downvoted. –  T.E.D. Jun 17 at 16:05
