Junkers Ju 390: The German Bomber That Almost Brought the Blitz to New York
During WW2, the Germans were developing a long-range bomber to reach U.S. soil. This was called the Junkers Ju-390 and it would have been a terrifying prospect.

The Junkers Ju-390 could have brought the horrors of the London Blitz to New York. Despite several prototypes being built and tested, they were never used in anger.
The program would ultimately be a failure but the idea of a transatlantic "New York Bomber" was a very interesting one.
If it had succeeded it could well have turned the tide of the war. Both from a tactical point of view but also a psychological one.
Would Germany have used them to bring the Blitz to America?
Would they have begun a terror campaign on the cities of the U.S.? Could they have delivered nukes?
We will never know.
The Plane
The Junkers JU-390 was intended to be a long-range heavy bomber designed to strike far-off targets like America's East Coast during WW2.
The idea was to bring the horrors of massed bomb strikes to the civilians of America.
She was, in fact, a further development of her predecessor the Ju-290.
Both of these aircraft were multi-engined planes designed to deliver large amounts of ordnance to bear on the enemies of Third Reich.
Sources conflict as to how many aircraft were built and what their operational record was. Most state that a total of three aircraft were built, with the first two prototypes being the ones that flew.
These two were built in 1943, the first prototype flying in August from Dessau and the second in October from Bernburg, while a third prototype was started in 1944 and converted into the Ju390A-1, a bomber/reconnaissance aircraft.
This was intended for the Japanese Army Air Force and carried an armament of eight MG151/20 cannon, two each in three turrets and one in each beam position along with four MG131 machineguns in both nose and tail turrets, and 3,960lbs [1,800kg] of bombs.
Another source states that a total of eleven aircraft were built as Ju 390 aircraft were conducting missions across Europe that would have been extremely difficult for just two aircraft to cover.
This source states that an aircraft [presumably the first prototype], flying in a round trip between the 27 and 29 August 1944, flew from Norway across the Atlantic and part of Canada to take pictures of American industrial plants in Michigan.
After finally being discovered by the USAAF as it flew over New York, it disappeared back across the Atlantic, to be landed at an airfield near Paris by the co-pilot, Anna Kreisling.
Other sources state that the second prototype had an even longer fuselage and carried a FuG200 Hohentwiel search radar, five 20mm MG151/20 cannon and three 13mm [0.51in] MG151 machineguns.
This aircraft was delivered to Fernaufklärungsgruppe 5 based at Mont de Marsan in January 1944 for operational evaluation, with a test flight being conducted in that same month, flying from Bordeaux to within about 12 miles [19km] of New York before retuning.
This proved that the specification for a bomber capable of attacking New York from European bases was entirely feasible but the scheme did not proceed any further.
The Junker Ju 390 would have also been used in other logistical roles for the German war effort.
These included the strategic bombing of course but also patrol and reconnaissance duties as well as long-range transportation of men, equipment, and supplies.
The Ju 290A-5 was a fully operational combat aircraft, and appeared in the spring of 1944.
It had protected fuel tanks, armour plating for the crew positions, and redesigned beam gun positions.
Three Ju 290A-5s were retracted from FAGr.5 after delivery. All their armament was removed, and additional fuel tanks installed.
They made a non-stop trip to Manchuria, and a similar flight back, to exchange documents and strategic materials with the Japanese.
They flew from Odessa and Mielic and carried aero engines and "special" cargoes out and rare metals and raw rubber and other strategic materials back.

Neither the raid to New York nor the trip to Manchuria happened with the FAGr 5 unit.
- Official sources in the BA/MA archives in Freiburg covering the unit;s particpation during the war with the Ju 290 and 390 aircrafts.
Three aircraft were converted with extra fuel tanks in Spring 1944 at Finsterwalde, and re-termed Ju-290-A9 variants.
They had been transferred to I/KG200 in April 1944 and the claims refer to their alleged flights to Manchuria after FAG.5 service.
They were flown by Major Gartenfeldt and Hauptman Braun; Hpt Braun's co-pilot was Lt Pohl.
They were based at Vienna's Neustadt airport and Prague's Rusyne airport under the codename CARMEN. Actually the book also mentions long range missions over Russia flown from Roumania.
Other units also flew Ju-290 prior to 4 April 1944 were Luft Transport Staffel 5 and Luft Transport Staffel 290.
Hauptmann Braun of LTS-290 apparently later flew Manchukuo missions for I/KG200 so is it possible that flights from Odessa were flown by LTS-290 before Odessa fell to the Russians ?
The Führer's Kurrierstaffel which is known to have flown special missions to Japan with an Me-261 aircraft early in the war also operated Ju-290 aircraft and the Me-264 which was supposed to fly Hitler into exile in Japan.
Athor William Stevenson reported in his book "The Bormann Brotherhood" that Maj Gen Wilhelm Monkhe was negotiating capitulation of Northern Germany and Denmark to Soviet forces in return for Hitler's escape into exile in Japan in 1945.
An armed long distance reconnaissance version [Me 264A] would have been equipped with three Rb 50/30 cameras, and armed with one MG 130/2, one DHL 151Z, one MG 151 and perhaps two MG 131 for the lateral positions.
According to a study dated 27 April 1942, the long distance aircraft should be able to fly reconnaissance missions as far as Baku, Grosnyj, Magnitogorsk, Swerdlowsk, Tiffis or Tshejabinsk in the USSR, and flights to Dakar, Bathurst, Lagos, Aden and southern Iran were also reachable.
Not only were New Jersey and New York in the U.S. within range, but also targets in Ohio, Pennsylvania and even Indiana.
In addition, there were plans to station some Me 264s on Japanese bases on islands northeast of the Philippines, to fly reconnaissance missions as far as Australia, India and much of the Pacific area.
A fourth Ju-290 aircraft was transferred to I/KG200 and then converted back to a "civilian" aircraft on Lufthansa's fleet.
Ju-290 A-5 werk no 110178 served with FAGr.5 [Ffernaufklärungsgruppe] from February 1944 until 4 April 1944.
It then became 9V+DK with I/KG200 from 4th April 1944.
It was withdrawn and rebuilt at Tempelhof into a civil aircraft in September 1944 and completed October 1944.
Flugkapitän Paul Sluzalek flew this aircraft from Prauge to Barcelona on 26 April 1945.
It may have carried SS Lt Gen Hans Kammler and SS Col Adolf Eichmann as some of its passengers.
Regarding the supposed Ju 390 flight to Manchuria under Lufthansa [civilian airliner] markings, the story goes that there were problems with planning this that went beyond the merely technical.
The best route and the one initially [supposedly] considered, would have been from northern Norway east across the frozen Arctic Ocean, with a final jog south over Siberia.
The Japanese, however, were practically hysterical at the thought of a German overflight of Russia to Manchuria provoking Russia to declare war on Japan.
The second route would have been a southern one, slightly more direct but infinitely more dangerous, across the Caucasus from forwarding German bases in the Balkans or Ukraine.
The plane used would have to have been the V. 2, whose range was enough to make the trip. In-flight refueling tests were made with the Ju 390, and it was at least theoretically possible to get there.
Based upon a German newspaper article from the 1950s, with testimony of persons involved, Ju-290 flights, in Deutsche Luft Hansa [civilian aircraft] markings, were conducted from Bulgaria to Nighsia [now Ningxia].
On the Black Sea coast at Bourgas the French built a an extremely long runway for long range flights in the 1920s.
Until 5 September 1944, Bulgaria was ostensibly neutral and maintained diplomatic relations with both Moscow and Berlin. For that reason a Deutsche Luft Hansa flight from Bulgaria to China would not have caused Japanese objections.
The route from Bourgas beneath the Crimea, northern Caspian and Arial Seas then down to Ninghsia is approximately 3,500nm which is within the 3,800nm capability of a standard Ju-290.
Those aircraft converted for the Manchurian flights had a range of 4,200nm and therefore a safe reserve of 700nm.
From 1942 Japan objected to overflights of the Soviet Union by Luftwaffe aircraft, so subsequent connecting flights were made by aircraft in DLH registrations.
In February 1944 former Deutsche Luft Hansa pilot Luftwaffe Flugkapitän Rudolf Mayr was placed in charge of the Manchurian flight operations.
Trial flights to China began with Ju-290A-5. It adopted a civil code for DLH operations to Ninghsia, China. This aircraft was destroyed by air raids at Reichlin in 1945. I
In March 1944 three other Ju290 aircraft were converted for flights to China.
One, from February 1944. became T9+VK. It was attacked on the ground at Finsterwalde in April 1944 and scrapped at Travenmünde in September 1944.
T9+UK, was lost whilst on the ground refueling to straffing fire by four Soviet flown Hurricanes near the village of Utta, near Astrakhan.
The third conversion, T9+WK, was attacked over the southern eastern front in May 1944 and returned from the mission beyond hope of repair.
In December 1944 Ju 290A-3 was converted for a mission to China to carry VIP Ulrich Kessler, but work on the aircraft was interrupted by Allied air raids and the aircraft was blown up in May 1945 to prevent capture.
Albert Speer spoke after the war about a Ju-390 flight via the Polar route - the date mentioned was 28 March 1945.
Plans for Japanese manufacture of the Ju-390 were to be shipped by U-Boat after the deal was concluded 28 February 1945.
The only U-Boat to Japan after this date was U-234.
This U-boat suffered an underwater collision with another U-Boat in the Kettegat in March 1945 so had to put into Christiansand in March 1945 for repairs.
U-234's radio man Wolfgang Hirschfeld wrote in his book "Atlantic Farewell" that after the collision urgent cargo was offloaded for a proposed flight to Japan.
An ItalianSavoia-Marchetti SM.75, was prepared for a Rome-to-Tokyo flight.
Ready on 9 June 1942, it was designated the SM.75 GA RT [for "Rome-Tokyo"].
Its pilot, Lieutenant Colonel Antonio Moscatelli, was placed in charge of the overall operation, which in addition to providing Italy with propaganda about Italian aviation prowess was to carry new codes for communications between Japan and her Axis partners; the Italians believed the British had broken the existing codes.
The flight was made difficult to perform by the extreme distance involved and the need to fly thousands of kilometers through the airspace of the Soviet Union, a country with which Italy was at war.
Taking off from Guidonia Montecelio at 05:30 hours on 29 June 1942, the SM.75 GA RT landed later that day 2,030 kilometers [(1,260 mi] away at Zaporozhye in German-occupied Ukraine, the easternmost airfield available to the Axis powers.
At 18:00 hours on 30 June 1942, carrying no documents or correspondence that might embarrass the Japanese [who were not at war with the Soviet Union] and with its crew under orders to burn the aircraft and its documents if forced down in enemy-held territory, the overloaded SM.75 GA RT made the difficult and potentially dangerous takeoff from the grassy 700-meter [,297-foot] runway at Zaporozhye.
Operating under strict radio silence, the aircraft continued unscathed through the night—despite encountering Soviet anti-aircraft fire, bad weather conditions, and a Soviet fighter, probably a Yakovlev Yak-1—flying over the north coast of the Aral Sea, skirting Lake Balkhash and the Tarbagatai Mountains and over the Gobi Desert.
Maps of Soviet positions proved inaccurate, and Moscatelli had to climb to 5,000 meters [16,404 feet] to avoid detection, causing the aircraft's oxygen supply to run out earlier than planned.
A sandstorm over Mongolia also endangered the SM.75 GA RT, but its crew sighted the Yellow River at 22:00 hours on 30 June 1942 and, on the last of its fuel, landed 6,000 km [3,700 mi] east of Zaporozhye on the 1,300-meter [4,270-foot] runway, at Pao Tow Chien, in Japanese-occupied Inner Mongolia, at 15:30 hours on 1 July 1942.
The aircraft was repainted with Japanese markings so that it would be safe in Japanese airspace, took an interpreter aboard, and then flew the final 2,700 km [1,700 mi] leg of the journey to Tokyo.
The SM.75 GA RT departed Tokyo on its return journey on 16 July 1942.
Arriving at Pao Tow Chien, its Japanese markings were removed and replaced with Italian ones. It took off at 21:45 hours on 18 July 1942 from Pao Tow Chien, retraced its route, and, after 29 hours and 25 minutes in the air and having covered 6,350 kilometers [3,950 mi], it landed at Odessa in the Ukraine.
Moscatelli then completed the operation by flying the aircraft on to Guidonia Montecelio.
The Italians publicised this event on 2 August 1942 despite the Japanese government's reluctance for diplomatic reasons, which cooled relations between the two countries; Tthe Italians made no attempt to repeat the flight.
IIn response to the flight made by the Italian Savoia-Marchetti S.M.75GA. the Japanese decided to forge a link with Europe, but wished to avoid Soviet-controlled airspace.
The easiest route was that taken by the Italians, following the great circle route, but General Tojo opposed this because it implied a violation of Soviet airspace. Japan was not at war with the Russians and Tojo wished to avoid either provoking them or asking their permission.
Development work was restarted on the A-26/Ki-77 project, and the first of two prototypes flew on 18 November 1942. The prototype suffered from persistent oil cooling problems which required many changes before being solved, delaying further flights into July 1943; while working on these engineering issues, Tachikawa built a second aircraft.
Colonel Saigo considered the so-named "Seiko" [Success] mission absurd and suicidal, but the crew was aware of the hazards of the mission; they even had a personal dose of poison to kill themselves if forced down in enemy territory.
The pilot was Juukou Nagatomo, the co-pilot was Hajime Kawasaki, Kenji Tsukagoshi and Noriyoshi Nagata were flight engineers, and Motohiko Kawashima was the radio operator.
Three Army officers were also carried as passengers, two of whom were military attachés. They departed Japan on 30 June 1943 for Singapore, where the airstrip had to be lengthened by 1,000 meters to assure a safe takeoff. Finally, the aircraft took off at 7:10 on 7 July 1943 with eight tons of fuel, ample to reach Europe.
Their intended destination was the German airfield at Sarabus [now Hvardiiske, Crimea] but they were to disappear over the Indian Ocean.
British fighters likely intercepted them as they were aware of the flight and its route thanks to the ULTRA analysts at Bletchley Park decoding intercepted German communications to Sarabus warning of their impending arrival.
Slow, unarmed, without armour protection and with a substantial amount of fuel on board, the Ki-77 would have been vulnerable to Allied fighters, even had no mechanical problems occurred.
Two prototypes flew of a radically modified derivative, the Ju 390.
The idea behind this was simple: The wing center section panels, complete with engines and landing gear, where fitted twice. The fuselage was elongated.
In this was the four-engine Ju 290 was modified into the six-engine Ju 390.
The Ju 390V1 was equipped as as a transport aircraft, and the Ju 390V2 as a long-distance maritime patrol aircraft.
Only two prototypes were ever completed, the V1 and V2 and were quickly dubbed the "New York Bomber".
Ju 390 project pilot Haupt Hans Pancherz claimed after the war that only one Ju-390 was ever flown.
At a hearing before British authorities on 26 September 1945 Professor Heinrich Hertel, chief designer and technical director of Junkers Aircraft & Motor Works also asserted the Ju390 V2 had never been completed.
German author Friedrich Georg claimed in his book that Test pilot Oberleutnant Joachim Eisermann recorded in his logbook that he flew the V2 prototype [RC+DA] on 9 February 1945 at Rechlin air base.
The log is said to have recorded a handling flight lasting 50 minutes and composed of circuits around Rechlin, while a second 20-minute flight was used to ferry the prototype to Lärz.
The development of this mighty aircraft made the concept of trans Atlantic bombing a distinct theoretical possibility.
Thankfully for the U.S., it was to ultimately become yet another failed proposal in Germany's "Amerika Bomber" series of projects.
Right place, wrong time?
At the time of the Junker Ju 390 development, the philosophy of the German high command was to concentrate on medium bombers and fighter-bomber hybrids.
Partly because of this the full potential for the plane was never really appreciated.
The Ju 390 was, in effect, just a slight "upgrade" of the Ju 290 airframe with bigger wings [50 m wingspan] and a couple of extra engines.
This might also have contributed to the project's failure.
Compared to its predecessor, the Ju 390 also had a lengthened fuselage of 112 feet [34 m] to assist with its long-range capabilities.
The aircraft's defensive capabilities were also beefed up.
The Ju 390 had two 13mm machine guns in the ventral gondola and two 13mm machine guns on her beam, or waist, gun positions.
It would also have been equipped with a pair of 20mm cannons in a dorsal turret and single cannon on the tail.
All of this hardware was to be manned by a crew of ten.
These were spread between the flight crew and dedicated gunners.
No records exist about the intended bomb payload.
Powering the New York Bomber
Each full production Ju 390 would likely have had a similar complement of engines to the prototype Ju 390-V1.
The V1 was powered by 6 BMW 801D radial piston engines. Each engine could churn out about 1,700 HP [1,268 KW].
The prototypes had a maximum top speed of 314 mph [505 km/h] and provide an operational range of around 6,030 miles [9,700 km].
The aircraft also had a service ceiling of around 19,685 feet [6,000 meters]. Accordingly, the prototypes had an empty weight of 87,083 lbs [39,500 kgs] and a maximum take-off weight of 166,449 lbs [75,500 kgs].
Though each prototype might have varied slightly in specifications.
The Junkers Ju390 V1's first recorded flight was on 20 October 1943. This test flight was rather promising for the future of the project.
Her sister, the V2, was also test flown the same month. Testing of both aircraft is thought to have continued into 1944 when the project was officially canceled.
Fate of the Junkers Ju 390
Initially, an order for 26 of these mighty bombers was submitted but the cancellation of the project would never see this aircraft used in battle.
During June of 1944 resources were becoming very stretched for the Wehrmacht meaning any and all non-essential resources were to be focused on more pressing projects.
The Empire of Japan was also given permission to take on local production of the JU-390 in 1944. However, none were completed by the time of the end of the war in 1945.
Japan and Germany were using the "Harteck Process" of gaseous Uranium centrifuges.
Germany in 1944 was shipping both Uranium ores and centrifuges to Japan by U-Boat.
Design work was carried out on a bomber-reconnaissance version of the Ju 390.
Considerable interest was displayed in this ultra-long range aircraft by the Imperial Japanese Army Air Force.
In the autumn of 1944, the Japanese government acquired a manufacturing license for the Ju 390A-1.
Under the licensing agreement, detailed manufacturing drawings were scheduled to be handed over to the Imperial Japanese Army's representative, Major-General Otani, by 28 February 1945.
There is no record of this part of the agreement having been fulfilled.
No reference can be found to this Major General Otani mentioned by Russian historians, however ULTRA decrypts of diplomatic signals from Japan's embassy in Berlin concerning the voyage of Japanese submarine I-52 refer to a General Kotani in Germany requiring return passage in connection with transport back to Japan.
Masao Kotani [14 January 1906 – 6 June 1993] was a Japanese theoretical physicist, known for molecular physics and biophysics.
These same signals refer to other passengers with higher priority.
James P O'Donnell interviewed key characters from Hitler's Bunker immediately after the war. O'Donnell made a point of tracing 250 survivors of Hitler's Bunker after the war and interviewed 100 of the most important ones.
He recounted in his book "The Berlin Bunker", interviews with Reichsminister Albert Speer and Hitler's pilot Hans Baur.
He reported Baur being coy about the Ju-390 aircraft but also said that right up to the last day at Berlin he could have flown the Führer anywhere in the world.
O'Donnell quotes Speer saying that Baur was fascinated with the Ju-390.
Speer also said "a Luftwaffe test pilot had flown a Ju-390 non-stop from Germany to Japan over the polar route. Baur would have known of this secret flight..."
At this point in the war, Germany was on a defensive footing.
The need for the long-range offensive bomber was far from a priority. In 1945 the Junkers-390 was officially stricken from the Luftwaffe's lists. The V1 prototype was destroyed on the ground as Allied forces were moving closer to the development facility.
The V2 was later captured by the Allies but her propellers had been removed to disable it.
Did the JU-390 make it across the Atlantic?
The most interesting part about the Ju 390 is that it may have actually been test-flown across the Atlantic.
The 'legend' goes that one of the prototypes, probably the V2, made it safely into American airspace and returned home without being detected.
The flight is supposed to have taken place between Mont-de-Marsan to a point around 20km from New York, and back.
This, however, is hotly debated. However, some tantalizing evidence points to a potential sighting in 1944.
Both prototypes were probably capable of making the round trip but to do so undetected is probably highly dubious.
Also, the recorded range of these planes is not quite far enough to make a round trip. From Mont-de-Marsan to New York is about 5,865 km, well over half the distance of its maximum range.
The final word
Despite two prototypes being built and tested the project would ultimately be terminated during the final stages of WW2.
If the aircraft's potential had been realized by high command earlier, the tides of war could have run out very differently.
Adolf Hitler badly wanted to bomb New York City. The Luftwaffe also had a prime target further in on the US mainland: the major automotive plants in Michigan busy churning out four-motor bombers that were wreaking havoc on the German homeland.
The generic name for development in this area was the "Amerika Bomber".
Both targets were within theoretical reach by war's end, but territorial losses and industrial damage prevented these ambitious objectives from ever being realized.
If even a few of the "New York Bombers" had bombed continental US targets, the US would undoubtedly have instituted costly air patrols, perhaps putting up observation and barrage balloons off the coast, and instituted naval surveillance for air attacks.
This could even have involved diversion of an aircraft carrier or two from the Pacific, picket lines of destroyers, and the like.
Such an additional defense programme would have cost the US greatly and diverted resources from other pressing tasks [just as Operation Paukenschlag forced costly coastal convoys and coastal air patrols on the US for the last few years of the war].
It never happened, though, with the JU-390 project basically abandoned once the Allies captured the French airfields in August 1944.
Could you picture swarms of Junkers Ju 390's assaulting and flattening American coastal cities like the Blitz of London?
What about if Germany had also completed its nuclear fission project?
Probably best not to.
According to Thomas Powers's book "Heisenberg's War" the idea of using the Me 328 as a parasite bomber within the Amerika Bomber program was explored.
It was to be carried by or towed behind either an Me 264 or a Ju 390 to attack New York City.
Plans for this tactic were hatched from a meeting between Generalfeldmarschall Erhard Milch and Generalmajor Eccard Freiherr von Gablenz at Berlin on 12 May 1942.
After release, the Me 328 pilot would release a bomb over Manhattan and then ditch at sea near a U-boat.
It would be a one-way trip for the Me 328, using all of its fuel in a one-way dash to New York Cit., with the host lane not having to get too close to shore in order to avoid detection.
Why this could not have been done much easier with a U-Boat carrying a small plane [the Japanese had lots of these aircraft carrier submarines, one of which they used to bomb Oregon twice and the French had one or two as well} is a bit unclear.
The idea was dropped in August 1942.
Manfred Griehl's "Luftwaffe Über Amerika" [Greenhill Books, 2004] contains details of the mid-air-fuelling project in Germany from its inception.
Trials were conducted over the Atlantic successfully in mid 1944 using Ju 290s.
The tests were conducted with Ju 290 V5 and a FW 58, then with two Ju 290s and one Ju 290 in Dessau and continued with another Ju 290 and Ju 390 V1 in Prague-Rusin. all in autumn 1943.
Further tests were planned in Mont-de-Marsan during the period May-July 1944, but there is no documentary evidence they actually happened.
It seems likely from the archive documents that there was a second Ju 390 aircraft, Ju 390 V-2.
Two test flights at Rechlin are recorded in the log of Oberleutnant Joachim Eisenmann for March 1945: an SS report at the Berlin Document Centre states that this second prototype was at Schweidnitz near Breslau in April 1945 for the evacuation of Kammler's Bell project.
It was known to have flown from there to Bodo in Norway after which German records are silent.
In an English language summary to his book on German advanced wartime technologies in Poland, Igor Witkowski, wrote:
SS-Sturmbannführer Rudolf Schuster was an officer of SS-RSHA Abt.III.
Schuster´s direct superior, SS-Obersturmbannführer Otto Neumann, masqueraded under various aliases post-war and was well known to the Intelligence authorities in Argentina.
From 4 June 1944 he was responsible for transport with SS-ELF [Special Evacuation Commando]., subordinated to Lower Silesia Gauleiter Karl Hanke [appointed successor to Himmler in Hitler´s Last Will and Testament].
The Commando performed transport duties under the cover name "Agricultural Fertilizers-Oskar Schwartz & Son'"
"In the Berlin Document Centre I found the officer's service sheet. From this it appears he was also at the 'Special Duty Office', SS-WVHA Amt A-V zbV.
"In his interrogation he told Allied investigators that in the second half of April 1945 a Junkers Ju 390 aircraft of KG 200 had taken materials related to the 'Chronos' and 'Laternenträger' projects to Bodo airbase in Norway. The aircraft was painted pale blue and bore Swedish Air Force markings.
"It took off from the airfield close to Schweidnitz [Swidnice] near Fürstenstein [Ksiaz]. and before the flight was heavily guarded by SS and covered with canvas.
"In Norway the transport was supervised by SS-Obergruppenführer Jakob Sporrenberg".
Eisenmann's flight-log is the most convincing evidence, that a second Ju 390 was completed. It states two test-flights on 9 February 1945, one flight of 55 minutes in Rechlin and the other 22 minutes with take-off in Rechlin and landing in Lärz nearby.
The flight-log does not state the registration numberof the aircraf, although it was obligatory to state it in the flight-log.
According to Eisenmann the aircraft remained in Lärz. Crew-members of the Ju 290's of FAGr. 5, who were in Lärz between 20 March 20 and 12 April 1945, do not remember having seen a Ju 390 there. And there is no known photo of Ju 390 V2, all existing photos of Ju 390 have been identified as showing V1.
The Argentine archive contains one single document reporting the arrival of a multi-engined German transport aircraft at a private aerodrome near Gualeguay, Entre Rios province, in May 1945 and carrying a device and materials which link it to Kammler's Polish project.
The Argentine Government made it known that it was anxious to receive weapons and technical projects from Germany immediately post-war and had a large budget for co-operation.
When Brazil entered the war in 1942, Argentina felt sufficiently threatened by Brazil to request the purchase from Germany of six U-Boats and a number of maritime reconnaissance aircraft. General Pistarini was behind the request.
While Hitler agreed in principle, on the advice of the German Foreign Ministry he ruled that it could not be done openly for fear of compromising Argentine neutrality, and Argentina would have to deal "under the counter" with the various suppliers, i.e. none of the production nor sales would be booked.
Exactly what was supplied is unknown.
There are no photographs nor records indicating that anything at all was supplied, except after the war four Second World War U-Boat engines were discovered in the Mercedes plant at Gonzalez Catan, where they were being used to supply the factory's power, and whose origin is unknown and undocumented.
This point to activities connected to Argentina which everybody involved is still at pains to conceal.
This document is from the Economics archive.
The very strong evidence for the arrival of "a multi-engined German transport aircraft" at Gualeguay, Entre Rios at the war's end appears in a 1945 Argentine Iintelligence document.
This document describes the laboratory equipment known as "the Bell" aboard the aircraft, and its purpose.
The information about the Bell did not become public knowledge until 1998, when the Polish archives released certain information about the experiments which matches precisely the Argentine description.
During the period 1943-1944 an air shuttle operated between Madrid and El Palomar military aerodrome, Buenos Aires, FW 200 aircraft were used.
The possibility that a very long range secret version of the Ju 390 aircraft had been constructed was suggested by Wolfgang Hirschfeld in his book "Atlantik Farewell: Das Letzte U-boot".
Oberfunkmeister Hirschfeld sailed aboard U-234 for Japan direct. The submarine carried a cargo of secret war material for the Japanese war effort and surrendered to a US Navy destroyer in mid May.
Hirschfeld stated that a "special version of the FW 200" with additional fuel tanks had been built to tranship the most important items of U-234 cargo to Japan, with a fuelling stop in Manchuria.
The idea had been scrapped when it was determined that it was not possible to reach Manchuria without overflying Soviet airspace.
Manfred Griehl also mentions FW 200 designs with trans-oceanic range enabled by long range tanks inside the aircraft hull.
The greatest known distance for a non-stop FW 200 flight occurred on 10 August 1938 when a passenger version flew from Berlin to New York.
lHirschfeld may have been confused between the types of aircraft to be used, or assumed it would be an FW 200, or deliberately misled.
Griehl mentiones "designs" but that does not mean anything proceeded beyond the blue-print stage.
The important point about not crossing Soviet airspace after the aircraft was converted was the designated cargo. The material to be shipped aboard the aircraft was the famous ten cases of "Uranium oxide".
This material could not be allowed to fall into Soviet hands under any circumstances, and the containers would have survived a land crash [being lead cylinders lined with gold].
The shuttle service between Madrid and Buenos Aires was known as Operation Condor.
The distance is about the same as that between Norway and Manchuria, and so if the FW 200 aircraft alluded to by Hirschfeld actually existed, no refuelling stop would have been necessary.
CEANA, the Argentine Congressional Committee enquiring into Argentina's Nazi connections post-war alleged that regular flights occurred between Spain and Argentina between 1943 and 1945.
This is supported by US Intelligence documents which describe the organisation and says it has a list of the pilots, although this has never been published.
Senator Santander led the accusations, but the Argentine armed forces, mainly Fascist dominated then and for decades afterwards, rejected any such flights as "impossible", since German aircraft of the time did not have the range to make the flight non-stop. [General Carlos van der Becke: "Destruccion de una Infamia"].
Argentine writers allege a refuelling stop in Spanish Sahara.
The Ju 290 was the likely choice, although the commencement date of 1943 does not make one aircraft more likely than the other.
Spanish Sahara is significantly nearer Buenos Aires than Las Palmas.
Professor Ronald C Newton in "El Cuarto Lado del Triangulo" [Ed. Sudamericana, publ Bs As 1995] mentions the courier service ran between S America and Europe [Rome and Madrid respectively] direct until suspended at the end of 1941.
The service was run by the Italian airline LATI and the German Condor airline. Diplomatic material was conveyed by both airlines.
The Ju 290 was the likely choice, although the commencement date of 1943 does not make one aircraft more likely than the other.
Spanish Sahara is significantly nearer Buenos Aires than Las Palmas. .
There is a document at NARA [CF-OP-2315, Naval Intelligence Box] "German Disembarkations at San Clemente del Tuyu" dated 18 April 1945 which mentions two FW 200 aircraft.
It reads:
"22.5.1944. General Faupel acting for Martin Bormann in Argentina wrote referring to two reports, one from Leute [German financier] and General Pistarini [Argentine Chief of General Staff] suggesting two FW 200 Condors since over-land shipments Spain/Cadiz no longer possible".
There is no doubt that U-Boats disembarked passengers in Argentina during the war:
The Abwehr/SS ran a lobster boat, the "Santa Barbara" which made two round trips between Europe and Argentina in 1943 and 1944.
This should have been impossible but is now undoubted and is one of the great mysteries of the Second World War.
This suggests that two FW 200 Condors were available, making the flight from Madrid to Buenos Aires possibly with the intermediate refuelling stop in the Spanish Sahara.
Documents from Junkers archives indicate the Ju 390 could have reached New York in January 1944, but not with any useful bomb load.
A Biography of Air Marshal Erhard Milch by David Irving notes that Milch favoured operating a New York mission by refuelling in Greenland..
The Junkers Ju 390 was extremely slow, limited in fuel consumption by the two-stage super-chargers on BMW801E engines to a practical ceiling of just 21,000ft, much too low to survive air defences around New York.
One of the Ju-390 Junkers test pilots, Flugkapitän Hans Werner Lerche referred to the Ju-390 as suffering from wing flutter in any but the shallowest of turns, thus it could not evade fighter defences on a bombing mission.
The Ju 390 was however an exceptional long range transporter. Ju390 test pilot Flugkapitän Hans Pancherz flew one to South Africa and back, via the Spanish port town of Villa Cizneros [modern Dhakla]
The second of at least three Ju-390 built appears to be located in waters off Owls Head, Maine where it went down, apparently on fire during a Hurricane in September 1944.
In September 1969 the "Daily Telegraph newspaper" published an article on the New York flight citing an interview with Junkers Test pilot Hans Pancherz who said he flew ''one of the Ju-390 transports'' [plural] on a test flight to South Africa and back in early 1944.
The V3 aircraft was flown to Japan who expressed an interest in 1943 to acquire the bomber version and produce it in Manchuria. A number of people such Armament Minister Albert Speer Flug and Hauptman Lerche claimed a Ju 390 was flown to Tokyo in January 1945.
Missions flown to Japan were the preserve of Sonderkommando Nebel. Speer said the Ju390 mission to Tokyo in 1945 was flown by test pilots, not millitary service pilots.
Evidence for Nazi airfield in Greenland
Germans are known to have operated weather stations in Greenland, however American units sent to eliminate these operations came under attack in December 1944 from two German bombers believed to be He 177 aircraft:
On 15 December 1944 Swedish newspaper "Sud Svensk Dagbladet Snällposten" carried a Reuters report about fighting on land in Greenland between US and German forces.
During one such skirmish the Americans were attacked by two-engine bombers which indicates a German airfield on Greenland. [Report, ABC, Madrid, 15.12,.1944]
It may be therefore that the Germans intended for a long range type to land and refuel in Greenland on a return flight or even perhaps on the outbound flight?
Ju 390 Bomber version
There was indeed a Bomber version of the Ju 390 recorded in Junkers archival material and reports were found describing actual flight testing of this bomber version.
However, the aircraft which reports alluded to have never been found.
The Ju-390 V1 prototype was parked up and abandoned at Dessau in November 1944 where it was photographed stripped of propellers. This aircraft was torched in January 1945.
After destruction of the derelict Ju390 at Dessau there are at least three further historical sightings of a Ju390.
Two Ju 390 test flights at Rechlin were recorded in the log-book of Oberleutnant Fritz Eisenmann for March 1945. The first flight was for pilot familiarisation, the second for transfer of the aircraft from Reichlin to ärz.
A 1945 report of the interrogation of an SS officer, archived at the Berlin Document Centre states a Ju 390 in Swedish markings took off from Schweidnitz near Breslau, Silesia in April 1945 bound for Norway.:
The arrival of a Ju3 90 at el Palomar air base was also cited from an Economics Ministry document at hearings by CEANA, the Argentine Congressional Committee enquiring into Argentina's Nazi connections post-war.
This alleged that regular flights occurred between Spain and Argentina from 1943 to 1945, flown via Vila Czneros on the Spanish Sahara coast.
The document cites the arrival of a multi-engined German aircraft at a private aerodrome near Puntas de Gualeguay, Entre Rios province, in May 1945, carrying laboratory equipment referred to as a “Bell” linked to Kammler's Polish project.
From this landing in Argentina the Ju390 finally flew east across the Rio Uruguay to land at a German owned ranch 60km east of Paysandu city near the village of “19 de Abril” where it was broken up. Parts were dumped in Rio Uruguay.
The Ju-390 V2 meanwhile was apparently the aircraft flown to within 12 miles of New York from France in January 1944.
The aircraft found in waters off Owl’s Head, Maine must have been either the V3 or the V4 prototype.
Junkers was paid in September 1944 by the Luftwaffe Quartermaster General for six completed Ju390 airframes [source author Geoffrey Brooks, "Argentina"] from the V2 to V7 protypes inclusive.
This payment is recorded in a contract let for series production of the Ju390 in September 1944.
A report dated March 1944 indicated Junkers Dessau would turn out 26 examples of Ju 390 by March 1946. The Luftwaffe series aircraft were referred to as A-series and examples for export to Japan were termed as B-series.
The Luftwaffe Quartermaster General on 1 December 1943, referred to the V2 aircraft as the first series production Ju390 aircraft. Plans for series production Ju390-A appeared with the contract issued in Septemer 1944.
All bomber production was halted by orders of Herman Göring 3 July 1944, however the Quartermaster General of the Luftwaffe issued a new contract to build a bomber version of the Ju 390 in September 1944, after bomber construction were supposedly halted
A Japanese airbase on Matua Island in the Kurils is today littered with German fuel drums dated from 1943 and German manufactured electrical transformers.
It may be that this was the eastern terminal of an air bridge performed by Ju-290/Ju-390 aircraft from Norway.
Göring planned to use these with suicide pilots to deliver a small nuclear weapon to New York.
The weapon in question had a 5kg sub critical nuclear device described in the famous Stockholm signal to Japan, sent between the Japanese embassy in Sweden and Tokyo 9 December 1944 describing the German “Uranium atom smashing bomb”
Air Marshal Erhardt Milch favored staging a New York attack through a refuelling airfield in Greenland. There are photos in existence of a Ju-390 on an airstrip in far northern Greenland.
II is known that both the Ju 290 and Ju 390 were capable of carrying extra auxilliary tanks inside the cabin, however whilst the New York flight was feasible with extra fuel tanks, this meant there was no payload, or bombload.
Any attack upon New York was either a one way flight or had to stage a landing in Greenland. Likewise flights to Japan probably required an intermediate refuelling stop.
Hybrid Me-264
The Me 264 was a four engined long range maritime reconnaissance bomber with very poor bombload capability, requiring extremely long runways by the standards of WW2.
Ultimately one was operated from northern Norway or northern Finland on a courier service to Japan, but the Me 264 was not the intended Amerika Bomber.
It is known that Sonderkommando Nebel operated long range Me264 missions over Russia after the V1 prototype had been destroyed which imply a second Me 264 prototype was flown.
Late in the war Me 264 wings fabricated at the Messerschmitt plant in Oslo, Norway were to be retrofitted to He 177 fuselages to create a hybrid aircraft of which little is known.
He-277 the real Amerika Bomber
The real aircraft design intended to launch an aerial attack on North America was the He-274 built at Toulouse in France by Heinkel.
In effect this aircraft was the He-177H also referred to as the He-177 A-4 with a pressurised cabin.
It was decided to fit production He 77 bombers with MW-50 equipped DB 603 engines, the aim being a delivery rate of 200 planes a month by January 1944.
In fact by January 1945 Heinkel five He 277 had been produced, out of an ultimate 14 aircraft.
After WW2 two prototypes were completed and used by the French Air Force for high altitude research.
The Nazis completed seven He 277 aircraft -close relatives of the He 274- and by 1945 Germany shifted these He-277 to Gardermoen airbase near Oslo, operated by the SS, not the Luftwaffe.
The purpose of these aircraft was to launch Tromsdorff D6000 hypersonic cruise missles from high altitude at New York.
Following WW2 the French continued to experiment not only with the He-274 aircraft, but also developed the Tromsdorff D-6000 concept.
Sadly the French scrapped their perfectly airworthy He-274 at Marsailles in 1953 along with several Ju-88 and Do-217 test aircraft.
The He274 is visibly similar but much different in proportions from the He277
Before any of these weapons systems could be used in anger, in July 1944 the US conveyed a threat to Hitler through the German legation at Lisbon to drop America’s Atomic bomb on Dresden within 6 weeks unless Hitler entered peace negotiations.
Reference to this was listed in the Project Epsilon transcript of secretly recorded conversations between Nazi nuclear scientists at Farm Hall in August 1945. It has also been corroborated since the war by Dr Paul Harteck.
It is ironic that the first load of spent fuel rods harvested from the Hanford Nuclear reactor were too contaminated with Plutonium-240 in 1944 for USA to carry out this threat, but Hitler had no idea of these problems.
This threat however prompted Hitler to open direct communication with London via the Romanian political opposition via radio in August 1944.
Churchill added a further threat to respond to any nuclear attack by ordering the RAF to drop Anthrax all over Germany.
Hitler was deeply intimidated by the Allied threat to use Anthrax which led during August 1944 to secret surrender talks with western allies excluding the Soviets.
The Soviets however captured Romania’s Marshal Antonescu who had been a conduit for such talks in September 1944 and through him learned that Washington had duped Moscow. This betrayal of Soviet Russia led directly to the annimosity of the ensuing Cold War.
People who speculate upon Germany’s Amerika bomber project miss the vital ingredient that these German aircraft were never intended to fly a return mission across the Atlantic.
Rather they were intended to launch pilotless cruise missiles.
The Amerika-Bomber project was an initiative of the German Reichsluftfahrtministerium to obtain a long-range strategic bomber for the Luftwaffe that would be capable of striking the United States from Germany, a distance of about 5,800 km [3,600 mi].
The concept was raised as early as 1938, but advanced, cogent plans for such a long-range strategic bomber design did not begin to appear in Reichsmarschall Hermann Göring's offices until early 1942.
Various proposals were put forward, including using it to deliver an atomic bomb [which Germany ultimately never developed], but they were all eventually abandoned as too expensive, and potentially consuming far too much of Germany's rapidly diminishing aviation production capacity after 1942.
How the Amerika Bomber might have looked
The Japanese effort was also directed towards bombing the US but like Germany’s project was also abandoned for lack of resources.
