Attempts have been made to develop a suitable computer code that can find solutions to the axi-symmetric penetration of an Earth Penetrating Warhead yielding complete space-time histories of the resistive force offered by the target medium. The consequent warhead deceleration and velocity reduction, the resulting axial compressive stress developed in warhead casing as the penetration process progresses into the composite target media consisting of hard concrete of specified thickness followed by earth soil have been discussed.

Intercept geometry of target aircraft and missiles play an important role in determining the effectiveness of the warhead. Factors such as fragment spatial distribution profile, damage capabilities, target and missile characteristics have been considered and visualised through computer graphics and optimum intercept angles have been arrived. Computer graphics has proved to be an important tool to enhance perception and conceptual design capabilities in the design environment.
