    There were multiple Me 262s sent via U-boat to Japan. Some 98 voyages began in Germany though all were not successful. The Kikka was a Nipponization of the 262 not a copy at all. It was smaller and lighter to accomodate the less powerful engines until stronger ones were available. Those were to be used on the actual 262 copy, the Ki 201 Karyu.

    Some of the transport U-boats were given to Japan and put into service with I-Boat designations.

    Thanks Adler, Marseille was the greatest shooter of them all round for round!

    Disassembled 262s did reach Japan via U-boat or I-boat. The huge Japanese cargo subs went to Germany too. Whether the 262 had Jumo engines is unknown. Most certainly the Japanese received the BMW units. Of this I am sure. The Me 163 was cloned as the J8M Shusui from Japanese engineers using its technical manual only.

    BTW that plane in the picture is a Me 262B not an A-1 as stated on the other website.

    Ya know how U-234 was on the way when the war ended? Here's what she had on board. Cargo containers were built to fit in the original mine shafts forward, midships and astern. Four cargo containers were carried topside. 240 tons of cargo were loaded for departure March 25,1945. Cargo included three crated Messershmitt Me-262 jet fighters and an ME-163 rocket-propelled fighter, Henschel HS-293 glider-bomb, extra Junkers jet engines, 10 canisters of uranium oxide, a ton of diplomatic mail, and over 3 tons of technical drawings, plus other technology (torpedo, fuses, armor piercing shells, etc.) Passengers were 9 high technical officers (one general) and civilian scientists. U-859 sunk in 1944 was carrying uranium.

    U-129 and U-195 had delivered 12 V-2s and an Me 262 to Japan in 1944.
    The U-195, a Type IXD, and the U-219, type VII, delivered their cargo to Jakarta 12/44. The U-219 was turned over to the Imperial Navy to become the I.505. The U-195 became the I.506. There were something like 98 known attempts or successful voyages to Japan so we can only imaging what other goodies were sent. Other U-boats were turned over to the IJN after successful voyages to become I-boats.

    These volumes discuss the acuisition of the 262 by Japan.

    In the same u-boat the Germans stored uranium, so that the Japs could make their own atom bomb as the Germans were almost finished. This uranium was captured and then used by the Americans against the Japs.

    Hard to say definitively if that uranium was used.
    Upon its arrival in the U.S., newspapers immediately reported on the unusual contents of the U-boat. There were French cognacs and 240 tonnes of weapon components for delivery to the Japanese ally. The most important part of the shipment, however, was 560 kg of uranium. As written on the U-boat manifest, the top-secret material was intended for the Japanese army.

    Was there really uranium on board? If so, what happened to it? Was it used for one of the two nuclear bombs dropped in Japan? Historians have not been able to determine conclusively. In the archives of Portsmouth, the records have been lost.

    A recent statement of John Lansdale, a former U.S. secret agent involved in the Manhattan Project (the top-secret US atomic-bomb project), has renewed speculation on the German U-boat's reported uranium shipment. Lansdale was responsible for Uranium Logistics in the Manhattan Project. The former head commander, now 84, recalled that the uranium was delivered directly to the nuclear-bomb complex in Oak Ridge: "The transportation papers passed over my desk at that time." His statement confirms the suspicion of many researchers. One of them, Vilma Hunt, an American nuclear expert and historian who worked on a book about the use of uranium in World War II, notes: "The builders of the atomic-bomb had at that time very little uranium to use. They scraped everything that they could get together, and used it in their atomic-bomb programme."

    Within the very short period from the end of May to the end of July 1945, would it have been possible to extract four kg of the uranium-isotope 235 from the 560 kg of uranium? Difficult, but not impossible, if one takes into account that 150,000 persons were working on the project to construct the bomb.

    Even if the four kg of U-235 had been extracted, it probably still would not have played a decisive role in the making of the U.S.' first atomic-bomb. In Little Boy (the bomb dropped on Hiroshima), about 60 kg of U-235 was used. Even without the German delivery, there would have been more than enough material for the necessary chain reaction. The German uranium could have been used in the two plutonium bombs: Trinity, tested in the New Mexico desert, and Fat-Man, dropped on Nagasaki three days after Hiroshima.

    The U.S. military was alarmed when it discovered the uranium on the German U-boat. U.S. military officials feared that Japan was more advanced in its atomic-bomb program than they had earlier thought. The fear was unfounded. Only 50 scientists had worked on the nuclear bomb program in Tokyo. Even if the U-boat had made it to Tokyo, the uranium would not have made a considerable difference. The Japanese simply did not have the complex technology for uranium enrichment.
