Abstract: A new type shaped charge warhead was put forward based on the energy concepts and its penetration capability was studied. Then the molding process and the penetration mechanism were discussed with respect to the shaped charge jet and the projectile produced by the new type shaped charge warhead. Based on the above analysis, the static steel target experiments were systematically carried out based on the new type shaped charge warhead in order to find the influence of the key configuration parameters and the match between the small angle liner material and the large angle liner material on the penetration results. The experiment results revealed that at the optimal stand offs of the new type shaped charge warhead and the EFP, the penetration capability of the new type shaped charge warhead could achieve an increase of about 50{\%} from the penetration capability of the EFP with a comparative diameter of their craters under the same charge and casing conditions.
