An artillery projectile for firing from an artillery gun, mortar or artillery rocket launcher. The artillery projectile includes a body, a payload with a number of inert fragments located within the body, a booster motor associated with the body for accelerating the body with the payload to a penetration velocity, and an opening arrangement associated with the body and deployed for initiating release of the fragments. The artillery projectile further includes a control system causally associated with the booster motor and the opening arrangement. The control system is configured to generate a first command to actuate the booster motor and a second command to actuate the opening arrangement.

1. An artillery projectile for firing from an artillery gun, mortar or artillery rocket launcher, the artillery projectile comprising: (a) a body;(b) a payload including a plurality of inert fragments located within said body;(c) a booster rocket motor associated with said body for accelerating said body with said payload to a penetration velocity;(d) an opening arrangement associated with said body and deployed for initiating release of said fragments; and(e) a control system causally associated with said booster rocket motor and said opening arrangement, said control system including a data storage device storing at least one parameter, said control system being configured to generate during a terminal portion of flight of the artillery projectile a first command to actuate said booster rocket motor and a second command to actuate said opening arrangement, wherein a time between actuation of said booster rocket motor and actuation of said opening arrangement is determined at least in part by a value of said at least one parameter. 2. The artillery projectile of claim 1, wherein said inert fragments have an aspect ratio greater than 3:1. 3. The artillery projectile of claim 1, wherein said inert fragments are selected from the group consisting of metal rods and metal darts. 4. The artillery projectile of claim 1, wherein said opening arrangement includes an actuator deployed to disperse said inert fragments in a direction perpendicular to a direction of flight of said body. 5. The artillery projectile of claim 1, wherein said body is a roll-stabilized body, and wherein said opening arrangement includes an actuator deployed to release a retaining structure preventing dispersion of said inert fragments. 6. The artillery projectile of claim 1, wherein said opening arrangement includes a roll-generating pyrotechnic motor. 7. The artillery projectile of claim 1, wherein said control system is configured to allow independent setting of a time for generating said first command and a time for generating said second command. 8. The artillery projectile of claim 1, wherein said control system is configured to allow setting, during flight of the shell, of a time for generating at least one of said first command and said second command. 9. The artillery projectile of claim 1, wherein said control system is located within said body. 10. The artillery projectile of claim 1, wherein said control system includes: (a) a communications device located within said body; and(b) at least one processor unit in communication with said communications device and housed separately from said body. 11. A system for correcting flight of an artillery projectile to a target comprising: (a) the artillery projectile of claim 1;(b) a trajectory monitoring arrangement deployed to monitor the trajectory of said artillery projectile in flight, wherein said control system is in data communication with said trajectory monitoring arrangement, and wherein said control system is configured: (i) to store at least one parameter defining a planned time of generation of said first command;(ii) to process data from said trajectory monitoring arrangement to assess a ranging inaccuracy; and(iii) to adjust said time of generation of said first command to reduce said ranging inaccuracy. 12. The system of claim 11, wherein said control system is further configured to determine a time for generation of said second command as a function of at least the adjusted time of generation of said first command. 13. The artillery projectile of claim 1, including a propulsive torque motor deployed to generate rotational velocity around a longitudinal axis of the projectile. 14. The artillery projectile of claim 13, wherein said control system is additionally configured to actuate said propulsive torque motor. 15. A method for operating an artillery projectile comprising the steps of: (a) providing the artillery projectile of claim 1;(b) receiving a set of desired impact conditions including a range and a dimension of a dispersion pattern;(c) deriving required settings including: a launch elevation, a first time for initiating said booster rocket motor and a second time for actuating said opening arrangement, said settings corresponding to the set of desired impact conditions;(d) setting said control system so as to initiate said booster rocket motor at said first time and to actuate said opening arrangement at said second time; and(e) firing said artillery projectile at said launch elevation. 16. The method of claim 15, wherein said set of desired impact conditions includes an impact velocity.
