Bremen-class Patrol Frigate

The eight F122 Bremen-class frigates of the German Navy were commissioned between 1982 and 1990. The design is similar to the Dutch Kortenaer-class but uses a different hull and propulsion system. 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. This class of ship was one of the last to be constructed under post-war displacement limitations imposed by the WEU on West Germany. All eight Bremen-class frigates will be replaced by the planned four Baden-Württemberg-class and six MKS-180 frigates, starting around 2016. Until then, the Bremen-class serves as the backbone of the German Navy.
