FIELD: underwater acoustics, underwater systems of remote control, underwater telecontrol subsystems. SUBSTANCE: radio underwater acoustic device for remote disconnection of underwater article and for control over its position on sea surface has command and final-control units. Command unit incorporates channel of emission of underwater coded wide-band control signals, channel of reception of radio signals and channel measuring present distance. Final-control unit includes channel of reception of underwater coded wide-band control signals, channel of actuation of control signal and channel of emission of radio signal. EFFECT: possibility of remote disconnection of underwater article, visual designation of its position, high-accuracy determination of distance between craft and final-control unit. 3 dwg
