To enhance the destructive capability of torpedoes and other underwater weapons shaped charge warheads against double-layer submarine structures

three types of shaped charge warheads were designed: single hemispherical liner

conical- hemispherical liner

and double hemispherical liner. Tests were conducted on a 1:3 scale model to evaluate the effectiveness of warheads with different liners against underwater targets. Through comparative analysis of the damage patterns on the target plates

one conical-hemispherical liner and one double hemispherical liner were selected as full-scale warhead prototypes. Subsequently

full-scale underwater warhead damage tests were conducted. Experimental results indicate that both full-scale shaped charge warheads can completely penetrate the equivalent target plate of a double-hulled submarine structure

composed of 10 mm non-pressure hull

1000 mm intermediate water layer

and 40 mm pressure hull

achieving a penetration depth exceeding 130 mm into the subsequent target plate. Under the same conditions

the total penetration depth of the conical- hemispherical liner is approximately 1.6 times that of the double hemispherical liner

demonstrating its superior armor-penetrating capability. These findings offer insights and experimental validation for the design of underwater weapon warheads and the protection of naval vessels.
