Aluminum projectiles with velocity of 9.7 kmsec and beryllium projectiles with velocity of 15.5 kmsec have been used to produce craters in aluminum and aluminum alloy targets. Results indicate that the influence of the mechanical strength of the target in determining final crater dimensions extends unimpaired for impact velocities up to 15.5 kmsec. These data have also been used to verify the linear dependence of crater volume on projectile energy.
