ABSTRACT:
A device for underwater missiles for use against submerged submarines, said missiles including a housing (1) having a front portion, intended to contact the outside surface of a submarine. According to the invention, a tubular ring member (6) is rotatably attached to the front portion of the housing (1), said ring member (6) being arranged to take up a rotary movement in relation to the housing (1) when contacting the outside surface of a submarine. In order to facilitate rapid acceleration of the ring member (6) into said rotary movement, the ring member (6) is attached to the housing (1) by means of a ball bearing joint (7) or any other known low-frictional rotary joint or connection, and the mass of the ring member (6) is also considerably smaller than the total mass of the missile. The outer surface(s) of the ring member (6) is/are also preferably arranged with means intended to increase the frictional contact between the ring member (6) and the outer surface of a submarine on impact, e.g. a layer or coating of a material having a high frictional coefficient, an irregular surface, or means directed outwardly from the ring member (6).
