FIELD: construction.
SUBSTANCE: device is proposed to damage ice cover comprising an underwater vessel equipped with ballast cisterns, due to drying of which a trim is created to a stern and buoyancy force. In the bow there is a container with a reservoir in it, walls of which are made of corrugated elastic material. Inner sides of the container are equipped with remotely controlled relief valves, and the reservoir itself with the help of a flexible hose is connected with a source of compressed air, is attached to the bottom of the container with the help of slings, and being straightened by supplied air it acquires toroid shape.
EFFECT: increased efficiency of ice cover damage by an underwater vessel.
