[0021] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution of the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings of the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the described embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0022] Unless otherwise defined, the technical or scientific terms used herein shall have the common meanings understood by persons with ordinary skills in the field to which the utility model belongs.

[0025] The rear warhead is coaxially arranged with the cabin shell 7; while the front warhead is tilted downward at an angle relative to the axis of the cabin shell 7.
[0026] When the missile (or rocket) loaded with the tandem armor-piercing warhead approaches the armored target, the front-stage fuze 6 detonates the front-stage warhead, and the front-stage warhead explosion generates a jet that detonates the reactive armor covering the surface of the armored vehicle, eliminating interference for the rear-stage warhead to penetrate the main armor. At the same time, the rear-stage fuze 12 appropriately delays the detonation of the rear-stage warhead to generate a jet that penetrates the main armor and completes the damage mission. Since the front-stage warhead is tilted downward at an angle relative to the axis of the missile body, the front-stage jet will reach the reactive armor through a shorter path, and has a stronger detonation capability for the reactive armor, thereby better completing the combat mission.
