In this paper experimental analysis of ballistic limit velocity of autoclaved aerated concrete (AAC) targets under rigid projectile penetration is presented. Industrial blocks with dimension of 600*250*200(mm) were cut into 125*125*50(mm) samples, impacted by gas gun using three different nose shaped projectiles (flat, ogive and conic). In this study damage mechanism and penetration depth were investigated and compared with conventional concrete which revealed significant difference in the initial penetration and cratering phase. It is predicted that ballistic velocity limit for conical projectile is lower than ogive ones and flat noses have the highest. The result compared and the difference between penetration mechanisms and cratering were discussed and investigated.
