OVERVIEW: The Bremen-class frigate is 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.

DETAILS:  During the Cold War period, the ships' main war task was to escort convoys for reinforcement and resupply of Allied forces in Europe. They frequently took part in NATO Standing Naval Forces. Since 1990, all ships have served in additional supporting missions such as the embargo operations against former Yugoslavia in the Adriatic Sea or Operation Enduring Freedom against the international terrorism.

During their lifetime, the ships' equipment has frequently been modernized and a further adaptation of combat systems is foreseen in the near future.
