Abstract
A warhead designed for employment against a target having active armor protection comprises a forward shaped charge and a rear shaped charge. The forward shaped charge generates a core explosion whose speed is below 2,500 meters per second, and thus does not detonate the active armor, while the rear charge is formed of a high-performance, high-explosive charge and completely pierces the armor. A time delay of between 50 and 300 .mu.sec is employed for detonating the rear charge after the detonation of the first charge. This type of warhead is suitable for piercing rolled homogenous armor (RHA), or spaced, composite, or active armor, and can be fired by means of rockets, missiles, shells, etc.
