Not entirely true, FRiends.
Behold the USCGC Eagle (WIX-327) the Coast Guard training ship that was formerly the "Horst Wessel" of the Kriegsmarine. Taken as a war prize in 1945, she was renamed the "Eagle" and assigned to the USGC.
Interestingly, her hold was an exact mockup of a U-boat cabin, where Nazi submariners would train before the outbreak of WW2.
Fascinating info. Thanks. One of the things I love about FR..I learn something new most every day..
