Good info on the U234
http://www.uboatarchive.net/U-234INT.htmThe uranium it carried was used in the US bombs dropped on Japan, and the top LW officer was none other than Lieutenant General Ulrich Kessler a LW air defence expert.
There is a lot of controversy over the U234, it's mission, and the use of its cargo. Japan may have tested an atom bomb/device during WWII, but needed more uranium from the Germans to make a weapon. The Manhattan Project had achieved to produce enriched uranium, but not in the quantities needed. The uranium carried by the U234 was most likely delivered to Japan by the USAAF. Another controversy is whether U234 actually tried to reach Japan, or if it was traded to the Allies by Martin Bormann, the infamous Gestapo chief, in return for safe haven in the US.
All this makes for a frightening "what if". US with no uranium for a bomb, but the Japanese with two bombs, Me262's, LW defence expert and V2's.
Kapitanleutnant Fehler is on the right. Don't he look like a doppelganger for Jürgen Prochnow in Das Boot?
