Ensdorf class minesweeper
From Wikipedia, the free encyclopedia
The five ships of the Type 352 Ensdorf class are former Type 343 Hameln class minesweepers that have been upgraded with the TROIKA PLUS system.
The Ensdorf class have three modes to clear mine fields:
- TROIKA PLUS: This system employs up to four remote controlled Seehund (sea dog or seal) drones which perform the sweep. The drones are small unmanned boats that can simulate the acoustic and magnetic signatures of bigger ships to trigger mines. Their small size and special construction let them survive the effects of exploding mines unharmed.
- Mine hunting: Mines detected with the hull-mounted sonar can be identified and exploded with expendable Seefuchs (sea fox) ROVs.
- Classical minesweeping: Against moored mines the classical minesweeping using towed wire cutters to cut the anchors of mines can be conducted.
The Ensdorf class replaced the Type 351 Lindau class minesweepers in service with the German Navy.
