FIELD: technological processes.
SUBSTANCE: in areas where enemy vessel is likely to show up, plant of chemical or gas generator action or compressed air cylinders are installed on the bottom of water reservoir. They produce a flow of gas bubbles ascending to water surface to reduce water density in close proximity under bottom of vessel. Device comprises the following components arranged with the possibility of installation on water reservoir bottom - plant of chemical or gas generator action or compressed air cylinders. They are connected by means of pipeline hoses of high pressure through outlet valve with gas disintegrating nozzles. Device also comprises a receiver of coded signals, unit of control and decoding of arriving signals and autonomous source of supply.
EFFECT: simplification of realisation method.
