The eight F122 Bremen-class frigates of the German Navy was a series of frigates commissioned between 1982 and 1990. The design was based on the proven and robust Dutch Kortenaer class but used a different propulsion system and hangar lay-out. The ships were built for anti-submarine warfare as a primary task although they were not fitted with towed array sonars. They were also equipped for anti-surface warfare, while having anti-aircraft warfare point defences. The Bremen class frigates replaced both the Zerstörer 1 class destroyers and the Köln class frigates.
