N2 - In order to investigate the damage efficiency of smart micro torpedo armed with EFP warhead, and to reveal its penetration ability, experiment and simulation of EFP forming and penetrating underwater double-layer targets are carried on. In this paper, influence of the distance between EFP warhead and targets underwater is studied, which covers 0, 40, 120, 200, 280mm depth of water. In addition, a penetrator is exceeded by different kinds of buffer materials. The experiments show that, compared with EFP in the air, EFP formed by underwater weapon results in smaller holes on the double-layer target. With the increase of the depth of water, the projectile loses its mass and velocity and damage diameter of the target remains an approximate constant first and then decreases. Interestingly, the simulation demonstrates a unique damage mechanism different from that in the air, which affected by the penetrator and underwater shock wave.
