It has been shown that penetrator efficiency, i.e. the ratio of penetration to penetrator length PL, increases as the ratio of the penetrator length segments separated at a distance should improve performance when performance is measured in terms of total penetration. Numerical simulations are presented examining the performance of A. C. Charters 7 segment 18 gram kinetic energy penetrator at normal impact against a semi-infinite T4340 steel target. The two dimensional simulations compare the effects of the spacers used in Charters penetrator with a similar penetrator without spacers compare the performance of equivalent mass and diameter and equivalent mass and length monolithic penetrators to that of their segmented counterpart at velocities of 3.4 and 4.0 kms examine the effects on performance of spacing-to-diameter ratio and examine the use of penetration efficiency as a measure of the performance of segmented penetrators.
