Abstract

A sub-combat unit is arranged to be separated from a flying body over a target area, and includes a warhead, a target detector and two diametrically disposed carrier surfaces, each connected to a carrier arm and pivotally disposed about its own shaft located in a plane which is normal to the line of symmetry of the warhead and pivotable from a collapsed position in which the carrier arms and carrier surfaces connect to the circumferencial surface of the sub-combat unit, and to a position opened at 90.degree. at which both of the carrier surfaces form a retarding area for the fall velocity of the sub-combat unit and to impart to the sub-combat unit a rotation for scanning the target area in a helical pattern during the fall of the sub-combat unit towards the target area. Compressible damping devices are provided on the casing of the sub-combat unit which are compressed by the carrier arms during the flip-out movement of the carrier surfaces, and return stops for retaining the carrier arms and the carrier surfaces in a final flip-out position.
