Results of analysis of information obtained from photographs of a hypervelocity impact against a transparent target and from hypervelocity craters produced in impacts that involved the four possible projectile-target combinations of high-purity copper and aluminum are discussed. An equation for hypervelocity crater depth is derived. Hypervelocity crater depth data for the four possible projectile-target combinations of high-purity copper and aluminum are presented in table form and used in graphs to test the theoretical equations.
