WATER AREA PROTECTION SYSTEM Russian patent published in 2018 - IPC B63G5/00 

FIELD: hydraulic equipment.

SUBSTANCE: invention relates to the field of marine equipment and can be used to control the underwater environment and protect water areas from the unfriendly countries marine objects. Water area protection system includes located on the surface ship and / or shore station control station, spacecraft or aircraft, equipped with surface and underwater objects searching television, optoelectronic and radio engineering means, having communication line with the control station. System also includes the self-propelled autonomous unmanned underwater vehicle (AUUV) equipped with the sea objects searching hydro acoustic and television means, underwater sound communication means, explosive charge and its initiation device, repeater buoy with a transceiver device, having positive buoyancy and connected to then AUUV via wire and fiber optic cable with reel, buoy detaching device, regulating its surfacing depth due to the veer out wire and cable length, cutter for the wire and cable cutting. Control station is additionally equipped with launcher, computing device and rockets with underwater sound communication means, the protected area is equipped with the hydro acoustic navigation system.

EFFECT: enabling high secrecy, ensuring detection of the enemy sea object approaching the protected area, and the on-duty autonomous unmanned underwater vehicle guidance onto it to prevent the object entry into the protected area.
