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 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 even though they are not fitted with towed array sonars. They are also suited for anti-aircraft warfare and anti-surface warfare.
