Abstract
A fragmentation pattern is formed on a surface of a warhead using an etchant process. An etchant resistance material is coated on an interior surface of the warhead casing. A portion of the etchant resistant material is selectively removed by a directed energy process and an etchant is applied to the exposed portion of the warhead casing surface thereby etching the fragmentation pattern. Alternatively, a protective coating is applied over the entire surface thereby creating the fragmentation pattern.
