List of naval ship classes in service

The list of naval ship classes in service includes all combatant surface classes in service currently with navies or armed forces and auxiliaries in the world.

Cyclone-class patrol boat Omiš-class patrol boat The Osprey-class is a subclass of the Lerici-class minehunter 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.

Seehund can be controlled remotely or manually by an onboard crew (usually 3) for maneuvering in harbours or in training (the Seehund is too large to be carried by Ensdorf class vessels).
