Description: On the basis of index of fire potential the comparative analysis of fire power of zenithal (zenithal-rockets) complexes and zenithal complexes of direct protection is conducted on the basis of the hyperspeeds accelerating which can be used for the direct protection of objects from the shots of high-fidelity weapon. A conclusion is done that after the index of fire potential the zenithal complex of direct protection is the most powerful decimator HFW on the basis of electrodynamic cannon.
