In the German Navy Konteradmiral is equivalent to rear admiral, a two-star rank with a NATO code of OF-7. However, in the former German-speaking naval forces of the Imperial German Navy (Kaiserliche Marine), the Nazi Kriegsmarine, the East German Volksmarine and the Austro-Hungarian K.u.K. Kriegsmarine, Konteradmiral was an OF-6 one-star officer rank.
