  • Patent number: 11725918
    Abstract: A payload container for providing a horizontal dispersion pattern of sub-projectiles suitable for combatting surface targets is in the form of a cylinder and includes at least two sub-projectiles arranged in a core enclosed by a container wall, wherein the sub-projectiles are linearly disposed. In addition, a projectile and use of the same include at least one payload container or a plurality of sequentially arranged payload containers displaced by a displacement angle relative to each other. The displacement angle is predetermined in such way so that the sub-projectiles are vertically lined at the time when the mechanical force from the carrier shell disappears and the sub-projectiles are spread to the left and to the right, providing a horizontal dispersion pattern.
