Abstract: An advanced earth penetrating weapon (EPW) penetrates targets at higher velocity and achieves much deeper depth of penetration compared with a common EPW. The present paper introduces the experimental method of high-speed impact fired by artillery and the launch technique of sub-caliber projectile. An experimental study on the deep penetration of reduced-scale advanced EPW was conducted, and the highest impact velocity reached about 1.2 km/s. Analyses on the deformation and failure of projectiles and concrete targets were given in detail. Researched results confirm the feasibility of the concept of advanced EPW.
