Sachsen-class (F124)

The Sachsen class is a series of air-defense frigates operated by the German Navy. Developed following German reunification, the class was designed to replace the Lütjens-class destroyers. The German government ordered three vessels in 1996, which were constructed between 1999 and 2006 using MEKO modular construction. A planned fourth vessel was canceled.

The hull design is derived from the preceding Brandenburg class to maintain part commonality, though the Sachsen class incorporates reduced radar and acoustic signatures. The ships utilize a combined diesel and gas (CODAG) propulsion system, featuring independent shafts and variable-pitch propellers. For stability in high sea states, the class employs a Rudder Roll System. The vessels are configured with seven watertight compartments and were designed with weight margins to accommodate future equipment installations.

Optimized for anti-air warfare, the class utilizes a sensor suite centered on the SMART-L long-range surveillance radar and the APAR multifunction radar. These systems provide target detection, tracking, and guidance for semi-active radar homing missiles. Armament includes a vertical launching system for surface-to-air missiles, point-defense missile launchers, and anti-ship missiles. The ships are further equipped with naval guns, autocannons, and torpedo launchers. An aft flight deck and hangar support the operation of two helicopters. Modernization programs initiated in the 2020s include the integration of TRS-4D AESA radar systems to provide ballistic missile defense tracking capabilities.

The three ships of the class are assigned to the 2nd Frigate Squadron based in Wilhelmshaven. Service history includes frequent integration into United States carrier strike groups and participation in NATO Standing Maritime Forces. In 2004, the lead ship conducted live-fire missile evaluations at the Point Mugu range in California. In 2024, the vessel Hessen deployed to the Gulf of Aden as part of EUNAVFOR Aspides to protect commercial maritime traffic. During this deployment, the ship engaged Houthi-operated drones and was involved in a misidentification incident involving a United States MQ-9 Reaper.
