Summary

The threat imposed by rockets, artillery projectiles, and mortar grenades (RAM) is of major concern for military installations and objects, e. g. in Iraq or Afghanistan. A good portion of these attacks are undertaken with unguided rockets and mortar projectiles with calibers up to 120 mm, while this paper concentrates on the latter. A counter RAM system based on 155 mm HE projectiles shall intercept and destroy incoming targets in a safe distance of the installation. Therefore, the impact of fragments and a blast wave as active principles against a typical Russian mortar projectile with a caliber of 82 mm is investigated by applying different empirical equations. A response plot overlayed on the fragment map is derived from the detonation and penetration threshold. These results are input parameters for a statistical approach of estimating the ammunition consumption as a function of the multi shot kill probability.
