An experimental program has been undertaken to study the phenomenon of both normal and oblique impact of cylindro-conical and cylindrical projectiles on metallic plates, a domain where almost no test data is available. Hard-steel strikers of 12.7-micrometer nominal diameter and either 60-degree conical or blunt tips and blunt soft aluminum cylinders of the same diameter were fired at 2024-0 aluminum targets with thicknesses from 1.78 to 25.4- micrometer and at both mild steel and medium carbon steel with thicknesses up to 19.05-micrometer. Initial velocities ranged from about 20 to 1025 ms, achieved with the aid of a pneumatic cannon at low speeds and a powder gun in the upper velocity range. Initial target obliquity was varied from normal to 50 degrees.
