• the ROV has an ejector unit, a so-called launcher, with which the search and mine destruction unit is exposed.
• the search and mine destruction unit is determined by the APS of an im Surface ship positioned operator to the directed to the mine sonar beam of the mine hunting sonar.
• the search and mine destruction unit whose transponder signals as well as the mine echo signals are displayed in the mine hunting sonar display, is then controlled by the operator to the mine.
• the mine is inspected by means of the TV camera, and the search and mine destruction unit is brought to the mine by the operator in a location favorable for the destruction and then remotely ignited by the operator.

• Mine destruction unit is a relatively costly clearing device, but justified in certain applications, the time savings in the mine destruction cost of use.
• the search and mine destruction unit has not been designed as a disposable vehicle with weapons characteristics, but as a reusable underwater vehicle, which deposits only an explosive charge at the mine and before detonation of explosive charge and mine is overtaken by a surface ship again (Buschhorn and Schütz "mine hunting - a modern variant of the mine mine defense", yearbook of the defense technology, 1976/77, page 142 - 151). After recording the search and mine destruction unit by the
• the invention has for its object to provide a method for mine destruction, which minimizes the cost of the Räumungscuit and compared to methods that use a reusable search and mine destruction unit, brings a significant reduction in the clearance times with it.
• the inventive method has the advantage that by using a primary and a secondary vehicle, both unmanned and have its own drive, as an autonomous, so independent of a platform tandem cost-effective allocation of system components on the reusable primary vehicle and on the designed as a one-way vehicle, a torpedo-like weapon performing secondary vehicle is possible. As a result, the costs incurred by destruction of the secondary vehicle, can be kept quite low.
• the tandem travels autonomously to the mine with the knowledge of the position data of a previously located mine and with the aid of navigation data from an on-board navigation device of the primary vehicle. There, the primary vehicle brings the secondary vehicle by remote control directly to the mine and triggered by a corresponding ignition signal from the detonator of the explosive charge.
• the secondary vehicle from the Primary vehicle are placed in an optimal position for the detonation of the mine and held in this position until the primary vehicle has taken a safe distance from the mine.
• the adjustment of an optimal position of the secondary vehicle in turn allows a smaller explosive charge to bring the mine reliably detonated, so that the space required for receiving the explosive charge space in the secondary vehicle and the total weight of the secondary vehicle is reduced. This is essential for demining because then a larger number of secondary vehicles can be held and carried by the platform to a primary vehicle.
• the secondary engine representing a "mini-effector" can be placed much more accurately and with a significantly reduced amount of explosive, can cause reliable mine destruction.
• primary and secondary vehicles are interconnected by a cable, are transmitted from the primary vehicle to the secondary vehicle steering signals and drive power for the secondary vehicle and also an electrical ignition signal for remote release of the explosive charge is transmitted.
• the stretched between the primary and secondary vehicle cable length is controlled so that it continuously between the vehicles currently existing distance is adjusted. This prevents the cable - as opposed to a unwound and loose-hanging cable - from getting caught on objects or bodies or on exterior elements of the preceding secondary vehicle during approach to the mine and can break.

If the localized mine 33 is to be destroyed, the position data are stored in the memory 27 of the primary vehicle 11 and the two vehicles 11, 12 connected to one another by a connecting cable 24 are inserted into the water by means of a dispensing device 34 (FIG. 1) (FIG ).
• the tandem formed by the two underwater vehicles 11, 12 operates autonomously, in the primary vehicle 11 by means of the stored position data of the localized mine 33 and the navigation data of the navigation device 20 steering signals for both the primary vehicle 11 and for the secondary vehicle 12 is generated and given to the steering devices 15 and 16 of the two vehicles 11, 12.
