Three guns were mounted at Battery Goeben on Husøya island, near Trondheim, Norway and formed Naval Coast Artillery Battery (Marine Artillerie Batterie) "Goeben", later 1st Battery, Naval Artillery Battalion (1./Marine Artillerie Abteilung) 507 "Husöen". Another three guns were mounted at Battery Tirpitz on the Romanian coast, south of Constanța, from April 1941 to August 1944, when the battery was destroyed by the retreating Germans. The battery, like all Axis forces in Romania, was nominally under Romanian control, but operated by Kriegsmarine personnel, and contributed to the defence of Constanța in 1941. See also
