オットー・ハーン
"Otto Hahn"s keel was laid down in 1963 by Howaldtswerke Deutsche Werft AG of Kiel. She was launched in 1964 and named in honour of Professor Otto Hahn, the German chemist and Nobel prize winner, who discovered the nuclear fission of uranium in 1938. The first captain of the "Otto Hahn" was Heinrich Lehmann-Willenbrock, a German U-boat ace of World War II.
