The most recent officer of the German Navy to hold the rank is Admiral Joachim Rühle, who serves as Chief of Staff, Supreme Headquarters Allied Powers Europe (SHAPE) in Mons, Belgium since 2020.
However, as to German naval traditions the addressing in seamen's language of military people with any flag officer rank (OF-6 to OF-9) is "Herr/Frau Admiral".
In the Imperial German Navy, an admiral would be addressed as "Eure Exzellenz" (Your Excellency)[1] Its rank insignia, worn on the sleeves and shoulders, are one five-pointed star above a big gold stripe and three normal stripes (without the star when rank loops are worn).
Admiral was the second highest flag officer grade of the Volksmarine, equivalent to the three-star rank Generaloberst.
In the GDR Volksmarine there have been the three flag officer ranks Konteradmiral, Vizeadmiral, and Admiral.
