The eight F122 Bremen-class frigates of the German Navy are a series of frigates commissioned between 1982 and 1990. The design is based on the proven and robust Dutch Kortenaer class but uses a different propulsion system and hangar lay-out. The ships were built for anti-submarine warfare as a primary task although they are not fitted with towed array sonars. They are also equipped for anti-surface warfare, while having anti-aircraft warfare point defences. This class of ship was one of the last to be constructed under post-war displacement limitations imposed by the WEU on West Germany.
