Ensdorf-class (Type 352)

Summary

Description

The Ensdorf-class minesweepers are a series of five vessels utilized by the German Navy, serving as an upgrade to the Type 343 Hameln-class minesweepers with the integration of the advanced Troika Plus minesweeping drone system. The class was specifically developed to bolster mine-clearing capabilities and replace the preceding Type 351 Lindau-class minesweepers.

Ensdorf-class minesweepers are equipped with a multi-modal approach for mine clearance operations. Through the innovative Troika Plus system, up to four Seehund drones can be employed to undertake minesweeping duties. These unmanned small boats are capable of mimicking the acoustic and magnetic signatures of larger ships to actuate mines while being robust enough to withstand the detonations. For mine-hunting purposes, the ships make use of hull-mounted sonar to detect mines, which can then be neutralized using expendable Seefuchs (Seafox) remotely operated vehicles (ROVs). Additionally, the Ensdorf class can engage in traditional minesweeping methodologies involving towed wire cutters to sever the mooring of mines.

The Seehund ROVs form an integral part of the Ensdorf-class minesweeper's capabilities. These unmanned surface vehicles are somewhat substantial in size with a length of 25 meters and a displacement of 99 tons, hence too large to be carried aboard the Ensdorf-class vessels themselves. Seehunds are operated either remotely or by a manual onboard crew for delicate maneuvering in confined waters such as harbors or during training exercises. The design includes a life raft in case of emergency needs. The propulsion is provided by a Schottel Z-drive, allowing the Seehund ROVs to achieve speeds in the range of 9 to 10 knots.

The operational history of the Ensdorf-class minesweepers saw the ships retain their commission following their conversion from Type 343 to the improved Type 352 class. Notably, the Seehund ROVs employed on these ships were sourced from the retired Type 351 class, indicating a repurposing of assets for continued naval applications.

These vessels are now an integral component of the 5th Mine Sweeping Squadron of the German Navy, operating primarily out of Kiel, situated by the Baltic Sea. This squadron's strategic location underscores the importance of minesweeping operations in ensuring the safety of naval and commercial shipping in an area heavily trafficked and historically susceptible to mine threats.
