The shaped charge warheads are designed only based on one single liner absolutely today. Authors of this paper put forward a new combined model of shaped charge warhead based on the energy viewpoint and discusse mechanisms of formation and penetration of jet and projectile. Then the steel target experiments are systematically made based on the model in order to find the influence of the key configuration parameters on penetration results. The experiment results reveal that the penetration of new model shaped charge warhead can achieve an increment about 50% than the penetration of current EFP under the same crater and charging conditions. A design of new shaped charge warhead is put out against the ERA.
