Did interwar German naval service necessarily expose officers to foreign views?
Short answerNo. During much of Lütjens's interwar career, foreign visitors would have had to come to him. The Imperial German Navy had previously offered much broader overseas service.
NotesService in a navy did not automatically mean regular overseas travel. Lütjens spent much of the interwar period in torpedo boats, so encounters with foreigners generally depended on visitors coming to him. His earlier service aboard Hansa had included repeated world cruises. The contraction of German naval activity after the First World War sharply reduced that kind of exposure.
