German-planned Invasion of the United States

Before the winter of 1941, Germany appeared to be moving toward a swift victory over the Soviet Union. Alfred Rosenberg, Reich Kommisar for Eastern Affairs, was ordered to print the motto "Deutschland Welt Reich" (German World Empire) and Hitler made known his intention of further conquest following victory over Russia. These plans appeared to include an invasion of the United States.

In Autumn of 1940, the attack on the US was fixed for the long-term future. This appears in Luftwaffe documents, one of which dated October 29, 1940 mentions the "...extraordinary interest of Mein Führer in the occupation of the Atlantic Islands. In line with this interest...with the cooperation of Spain is the seizure of Gibraltar and Spanish and Portuguese islands, along other operations in the North Atlantic".

In July 1941, the Führer ordered that planning an attack against the United States be continued. Five months later, on December 11, 1941 Germany declared war on the United States.

Why did Adolf Hitler Declare War on the United States of America?

Armament related to the proposed United States Invasion

The Wehrmacht, in planning for the British invasion developed some types of airborne and amphibious tanks and other special heavy armour, later considered for an eventual invasion of  America:

Panzer I C Sd. Kfz. 101 Neuer Art, (Pz I Airborne Tank)

Panzer II amphibious (Schwimmpanzer II)

Panzer III M Sd. Kfz. 141/1 (Pz III Amphibious version)

Panzer III N Sd. Kfz. 141/2 (Pz III Amphibious version)

The Kriegsmarine, ordered the design of some aircraft carriers (Based on Akagi-Type Great Japanese Navy Flag-Carriers):


Graf Zeppelin Carrier

Peter Strasser/Deutschland Carrier

Europa Carrier(Project)

Potsdam Carrier(Project)

Carrier based Aircraft (such units were intended for equiping the Luftwaffe/Kriegsmarine 650th Geschwader):

  • Fieseler Fi 156C-0 (Recon-Liaison Carrier plane)
  • Fieseler Fi 167A-0 (Attack Bomber-Recon Carrier plane)
  • Heinkel He 50(Dive-Bomber/R Carrier plane)
  • Avia B 534(Dive-Bomber/Recon Carrier plane)
  • Junkers Ju 87C-0/1 "Cassar"(Dive-Bomber Carrier plane)
  • Junkers Ju 87D-4 (Torpedo-Dive Bomber Carrier plane version)
  • Junkers Ju 87E (Dive-Bomber Carrier plane, project)
  • Messerschmitt Me Bf 109T-0/2 (Fighter Carrier plane)
  • Messerschmitt Me Bf 109E (Fighter Carrier plane)
  • Focke Wulf Fw 190A-5 U14/15 (Torpedo-Bomber/fighter Carrier plane)
  • Focke-Wulf Fw 190F-8 U2/3/14 (Torpedo-Bomber/fighter Carrier plane)
  • Arado Ar 95B/195 (Torpedo-Reconnaissance Carrier plane)
  • Arado Ar 197(Carrier Basic Fighter Trainer)
  • Arado Ar 96B (Carrier Basic Trainer)

    The Luftwaffe "Amerika Bomber" designs for strike against United States

  • Messerschmitt Me 264 "Amerika Bomber"
  • Junkers Ju 390 A-1 "New York Bomber"
  • Focke-Wulf Fw 300
  • Focke Wulf Fw Ta 400
  • Sänger Amerika Bomber

    Also ordered for transport of airborne forces and light vehicles in planned British invasion were the ultra-heavy giant armed assault glider Junkers Ju 322 "Mammut". Such vehicles were supposed to be used in an invasion of America alongside the Messerschmitt Me 321 "Gigant" heavy transport glider.

    Use of 'V-weapons' against America

    The Luftwaffe analyzed the possible use of 'V-weapons' against the US in a plan to launch a squadron of Junkers Ju 290 long range recon aircraft armed with Fieseler Fi-103 (V-1) rockets. The Kriegsmarine considered a similar idea with submarine-based V-1/V-2 launchers against United States coasts. Similarly, the Wehrmacht created the "Division zur Vergeltung" (Reprisal Division) or "Div.z. V." through which a special unit was organized. From islands or just offshore, this unit would use the "Langrohrkanone LRK 15 F-58", also knowed "HDP Kanone" or V-3, or the ultra long-range version of the multi-phase mid-range missile V-4 "Rheinbote" against U.S. soil.

    Other special weapons were envisioned for possible use against the United States too, such as:


    The A9 was a further development of the "A4" rocket. No prototype was ever developed before the end of the war, although a variant, the A4b, was produced. The A9 would have been used as the upper stage for an intercontinental missile or a manned craft. The A10 was to have been used for the lower stage.

    Parameters of the planned manned A9-rocket:

    Length: 14.18 m

    Maximum diameter: 1.65 m

    Takeoff weight: 16,259 kg]

    Payload: 1,000 kg


    The A10, which was never built, was intended to serve as the first stage for the A9, to help it to reach an intercontinental range. New York City and other targets in the northeastern U.S. were its intended targets. Test Stand VII was built at Peenemünde for use in the A10's development.

    The A10 was designed to have a diameter of 4.12 meters and to exceed the A4 in its size. It was to be fueled with alcohol and liquid oxygen. The thrust of the engines would have been 235,000 kgf (2300 kN) with a 55-second burn time.


  • Operations supposedly related to the planned invasion of the United States

    Orders to send German saboteurs to U.S. territory, along with spies and collaborators

    German forces sent agents to Greenland to install a base for secret operations in the area, along with use of the radio station in Saint Pierre Miquelon Island, under the administration of France

    German submarine missions to Atlantic coasts and Caribbean area, with submarines such as U-134, U-853 and others.

    Maritime reconnaissance flights by German flying boats Blohm und Voss Bv 222 C-0 "Wiking" from France and Norway to the north and central Atlantic area to watch Iceland, Greenland, and the Canadian and coasts.

    The successful long range and evaluative flight and return to base of a Junkers 390, in August 1944, from Biscay coast in occupied France to within 20 Km of the U.S. coast, near New York State

    The alleged collaboration between Schutz Staffel (SS) and All American SS unit "Amerikan Frei Korps" or "George Washington Brigade" towards the invasion of the U.S. Also, some Americans were recruited to American versions of the German Wehrmacht and SS services to provide aid to invading German forces.

    The projected use of submarines with V-1/V-2 Launchers against American coasts.



    Also, the planned use of special mobile launchers from French coasts for launching one ultra long-range multi-stage V-4 "Rheinbote" missile or other similar type.

    A plan to use one Junkers Ju 290 long-range reconnaissance plane armed with four V-1 rockets against United States territory.

    A Kriegsmarine or Luftwaffe attack against the Panama Canal, U.S. territory at the time. The former would use submarines to strike the Atlantic side of the Canal. The latter would pretend a squadron of ultra long-range bombers from France to North Africa, were continuing to South America in support of a neutral country.





    Is there a possibility that Hitler could have managed to take advantage of political, regional, and ethnic divisions in America in the 1940s, and defeated the ‘Good Old USA’?

    It certainly would not have been possible for Hitler to stage a successful naval invasion across the Atlantic to take the Eastern Seaboard, irrespective of whether or not America succeeded in Europe. He simply did not have a Navy that was large enough for that task.

    Here are various ways in which the Germans would have defeated America, assuming that they had succeeded in their mission to conquer the Soviet Union:

    1. They might have attempted to conquer Alaska, based on their ability to control Siberia and the Arctic regions of Russia. From there, they would have rolled over poorly defended Canada, from which they would have launched a massive invasion from the sparsely populated North-Western U.S.

    2. Using the historic grievances that Mexico has, especially over territorial loss in the 1848 war, Hitler could have encouraged the Mexicans to stage a massive military invasion from the South (something similar to what their illegal are already doing). Given that many South Americans had pro-axis fascist feelings during the war, Brazil and Argentina could have send their own armies as well, to support the Mexicans. And, considering that Latin America continued to trade with Germany in the war years, Germany would have been able to move massive armaments and troops to South America, to support an invasion from Mexico. As a reward, Mexico would have been rewarded with the return of California, New Mexico and Arizona. The rest of South America would have had a chance to be freed from American regional dominance that has existed since the Monroe Doctrine.

    3. Hitler could have reached out to the anti-FDR right-wing, the likes of Charles Lindberg, Henry Ford, Rev. Charles Coughlin, and their many followers who were influential in the America First Movement. He could have used the resentment that Irish-Americans and German-Americans had for Anglo elites who wanted to save Britain, a nation that many in both groups disliked (Many Irishmen resented going to help Britain. The Republic of Ireland made a conscious decision to stay neutral in the war to the very end).

    4. Germany could have offered the South a second chance. If the South militarily supported the defeat of the Yankees, they could get back the Confederate States of America. The CSA would have been a fully independent right-wing nation that was allied to Germany, like Franco's Spain. They would have been allowed to preserve their system of segregation, a system that Germans approved of.

    5. In the 1940s, Eugenics was highly favored by both liberal and conservative elites in New England. American race scientists like H. Goddard, Carl Bingham, Madison Grant, and Lothrop Stoddard were standard readings in the school system in Nazi Germany. A shared interest in race issues would have brought the Nazis and the New England Eugenicists together.

    A combination of all those forces would have overwhelmed the FDR administration.
