A method is provided for retarding the movement of the flip-out target tracker during a final part of a flip-out without the contents or journalling of the target tracker being damaged. The flip-out target tracker is on a sub-combat unit which is transported by a carrier body to a predetermined target area in order to be activated at the target area during flip-out of the target tracker. The target tracker scans the target area during the braked fall of the sub-combat unit and identifies and combats targets by means of an integrated warhead. The retardation is effected with a flexible brake band. The brake band is initially folded and attached to the target tracker at a first anchorage point in the proximity of a portion of the target tracker which, during flip-out, moves the longest distance. The brake band is stretched past an elastically deformable damper body secured in a main portion of the sub-combat unit. The damper body is caused to be at least partially deformed by the brake band during the final stage of the flip-out phase so that the brake band is stretched between the first anchorage point and a second anchorage point in the main portion of the sub-combat unit on another side of the damper body compared with a point on the damper body where the body and the brake band first meet.

Flip-out mechanism for target trackers

A submunition which is arranged to be separated from a missile or projectile for example, a shell canister or the like, over a target area including an active part, in the form of a warhead, a target detector and means for imparting to the submunition a controlled rotation for scanning of the target area in a helical pattern during the descent of the submunition towards the target area. The target detector is displaceable in order to allow a free view at the side of the warhead. The two diametrically situated aerofoils are pivotable from a folded position, in which the aerofoils connect with the outer surface of the submunition, to a 90.degree. unfolded position, in which the two aerofoils form a braking area for controlling the rate of descent of the submunition. The two aerofoils are pivotally arranged via a double joint.

Subwarhead

A subwarhead adapted for separation from a missile, for example a carrier shell or the like, over a target area comprises an active part, a target detector and an arrangement which imparts a rotation to the subwarhead for scanning of the target area in a helical pattern during the descent of the subwarhead towards the target area, the target detector being arranged displaceably in order to allow a free view at the side of the active part. Two diametrically situated aerofoils are pivotable, each on its own shaft situated in a plane which is at right angles to the axis of symmetry of the active part, from a folded position, in which the aerofoils connect with the outer surface of the subwarhead, to a position folded out by 90.degree., in which the two aerofoils form a braking area for controlling the rate of descent of the subwarhead.
