Two sections of explosives are utilized in a shaped charged device to first accelerate liner material to high velocity and secondly to collapse the moving liner on a projectile\s longitudinal axis to produce a high velocity jet and slug. The apparatus utilizes the principle of superposition of velocity generated by sequentially activated explosives to attain jet and slug velocities having greater ability to defeat armored targets.

A shaped charge device which comprises: a hollow cylindrical shaped housing having a longitudinal axis; first explosive means, including an explosive charge having substantially cylindrical shape operatively disposed in one end of said housing, for generating a first detonation wave; detonator means comprising means for producing a single point or annular detonation wave in said first explosive means operatively positioned on the outer side of said first explosive means for selectively initiating explosion in said first explosive means; shaped charge liner means in abutment with and at the inner side of said first explosive means, said inner means forming a convex hollow toroid surface, convex in the direction of the said first explosive means, which deforms upon explosion into an approximate hollow open ended tube-shaped first slug expelled at a first velocity, preceded by a narrow first jet of high velocity gases of the explosion, said liner being metal which density is varied for use in defeating various targets, delay means comprising an annular shaped delay member placed to the rear of said liner means; said explosive means having a detonation velocity rategreater than said first velocity of said first slug, said second explosive means shaped as a hollow cylinder fitting within said housing, having an inside diameter slightly larger than the outside diameter, and length greater than length of, said first slug, placed to the rear of said delay means and initiated by a second detonation initiation wave transmitted from said delay means, said delay means delaying transmission of said second detonation initiation wave until said first slug is completely contained within the length of said second explosive means, whereby when said second explosive means is detonated, the said first slug is deformed into a second slug which is relatively rod-shaped, expelled at a second velocity, preceeded by a second jet of relatively high velocity gases of the second explosion,
