An apparatus for disabling of motor vessels moving in a waterbody. An energetic (i.e. explosive), as part of a floating assembly, is brought into contact with a motorized marine vessel's propulsion unit(s) and / or steering system, referred to generally as the underwater drive unit, due to the vessel's own motion relative to a floating line. The energetic then detonates and disables the underwater drive unit, thereby halting progress of the vessel while not harming any occupants thereof.

A magnetic mine countermeasure payload device with a non-magnetic plate, and magnetic elements, each having a north magnetic pole and a south magnetic pole, affixed to the plate in a magnetic array. A rotational shaft is coupled to the plate, with a motor coupled to the shaft, and an electrical power source electrically connected to the motor. The motor is configured to at least one of selectively rotate the magnetic array, thereby creating an AC magnetic moment in the magnetic mine countermeasure payload device, and not rotate the magnetic array, thereby enabling a DC magnetic moment in the magnetic mine countermeasure payload device.

The invention relates to a mine-hunting system (20) having a first and a second unmanned underwater vehicle. The first underwater vehicle (22) is designed to travel on a predetermined course (32) to an object (34) in the water and, during travel, to generate a positional image (50) by means of a sonar system (122) and to identify the object (34). In order to generate the positional image, the first underwater vehicle has the sonar system (122), an orientation and position sensor system (124), and a signal processing unit (126). The sonar system (122) has an array of waterborne sound transducers having at least one first and one second waterborne sound transducer (54, 56), wherein the waterborne sound transducers of the array of waterborne sound transducers are each designed to convert waterborne sound (130) into a corresponding electrical signal (132). The orientation and position sensor system (124) is designed to continuously determine poses (134) of the first unmanned underwater vehicle (22). The signal processing unit (126) is designed to carry out direction formation on the basis of the electrical signals (132) of the waterborne sound transducers of the array of waterborne sound transducers in order to continuously determine the position of reflections (62) in the waterborne sound (130) using a current viewing direction of the sonar system (122) and the direction formation and the position data (134) of the first unmanned underwater vehicle (22), and to enter said position into the positional image such that a contour of the surroundings of the first unmanned underwater vehicle is represented in the positional image on the basis of the sum of reflections (62). The second unmanned underwater vehicle (24) is designed to travel on the predetermined course (32) to an object identified as a mine, wherein the second unmanned underwater vehicle (24) and / or a base station is designed to monitor a current course (32) of the second unmanned underwater vehicle on the basis of the positional image (50) of the first unmanned underwater vehicle and, if necessary, to adapt said course; - wherein the second unmanned underwater vehicle (24) is designed to render the mine harmless.
