FIELD: the invention refers to shipbuilding particularly to ice-breaker ships.
SUBSTANCE: an ice-breaker ship has an above-water part which includes a control system, a milling cutters' drive, a passengers' mess; an underwater part which includes compartments for air, fuel, a propulsor; two lateral parts which have a communication system, a hydraulic drive for displacement in the vertical plane of the above-water part relatively to the underwater part and having at the front wedges for cutting-in and breaking ice. The front construction of the upper and the underwater parts are designed in such a manner that the ice plate getting between them is destroyed from arising stress of the bend.
EFFECT: increases speed of a ship's passage through the water area covered with ice at relative reducing of energy consumption for breaking ice.
