The Ensdorf class is a German Type 352 mine-countermeasure vessel class rebuilt from Hameln-class hulls into drone-control boats for the Troika Plus mine-sweeping system. Its service history centers on controlling Seehund unmanned surface sweep boats, mine-countermeasure support to German and multinational naval tasks, and a later Bundeswehr role as training, recruiting, and command-support vessels.

Role in Conflicts

Side
Unconfirmed conflict context

German Navy press releases document the Type 352 boat Ensdorf deploying with UNIFIL off Lebanon in 2007 and departing again in 2011 with Passau. The sourced mission role was maritime surveillance, arms-smuggling prevention, and support to Lebanese naval capacity rather than confirmed combat or mine-clearance action.

Mine-Countermeasure Method

The Ensdorf class was not just a conventional sweeper. Its Type 352 role made the vessel a control platform for remote mine-sweeping craft, while the remaining German Navy boats now serve mainly as training, recruiting, and command-support platforms.

Remote sweeping

The Seehund boats operate away from the control vessel and imitate ship acoustic and magnetic signatures to trigger mines at a safer distance.

Mine disposal

Specialist references describe the class using Seefuchs expendable mine-disposal drones after sonar detection of mines.

Current service

Bundeswehr material identifies Pegnitz and Siegburg as the two remaining Ensdorf-class boats, used for recruiting cruises and as command platforms when required.

Shipboard Air Defense

The ship's armament list includes two Fliegerfaust 2 launchers from 2000 onward.

Bundeswehr data describe ten MJ332 boats with non-magnetic steel hulls, Seefuchs/SeaFox mine-disposal drones, mine rails, diver facilities, and MJ332B, MJ332C, and MJ332CL mission fits, while former German hulls also served the UAE as Al Murjan-class mine-countermeasure vessels.

Bundesarchiv-linked records and specialist ship databases describe the boats as Class 362 coastal guard craft that became Class 394 inshore minesweepers, with ten Bundesmarine hulls entering service from 1966 to 1969 and three former German boats later forming part of Estonia's post-restoration mine-countermeasures force into the 2000s.
