Subprojectile to be expelled from a projectile

A subprojectile to be expelled from a projectile, including a bursting charge, ignition means for igniting the bursting charge, and arming means for preventing in a first and safe position, said igniting of the bursting charge, and allowing, in a second and armed position, said igniting of the bursting charge, wherein the ignition means includes a first ignition body connected to the subprojectile, and a second ignition body which is movable in relation to the first ignition body, the second ignition body being capable of sensing acceleration forces acting upon the subprojectile as a consequence of the expelling of the subprojectile from the projectile, the second ignition body also being capable of sensing deceleration forces acting upon the subprojectile after said expelling, the second ignition body being movable away from the first ignition body in response to said sensing of said acceleration forces, the arming means being shiftable from said safe position to said armed position in response to said moving of the second ignition body, and the second ignition body when subjected to said deceleration forces being capable of moving toward the first ignition body only when the arming means is in said armed position.
