The U-505, launched the 24th May 1941, served in the German Kriegsmarine until her capture the 4th June 1944 by the United States Task Force 22.3. The submarine was towed, secretly, towards Bermuda and the captured crew remained totally incommunicated from the outer world to preserve the secrecy of the capture. The victories acknowledged to the U-505 during wartime comprised eight ships sunk for a total of 45000 gross register tonnes. In 1954, the U-505 was donated to the Science and Industry Museum of Chicago, where she remains as the only surviving submarine of the Type IXC.
