A single stage kinetic energy warhead using multiple explosively formed projectile (EFP) liners in a stacked configuration is capable of breaching intermediate barriers and defeating a primary target. The main explosive charge is detonated and the subsequent shockwave causes the front liner to be shaped to breach an intermediate barrier. The main liner is formed into a more compact rod-shaped projectile designed to defeat the main target. The weight and volume of the stacked liner configuration of the present system is significantly lower than the weight and volume of current systems. The present system requires a single firing explosive train eliminating developmental cost and complex fusing. The present system utilizes explosive detonation, simplifying the delivery of a projectile and eliminating the need for a missile delivery system. The size and simplicity of the present system allows for portability and use by an individual.

1. A single stage kinetic energy warhead utilizing a barrier-breaching projectile followed by a target-defeating explosively formed projectile, the warhead comprising:a housing having an inner surface; an explosive charge disposed within the housing; a first liner that is placed against the explosive charge within the housing; a plastic insert that is placed against the first liner; a second liner that is placed against the plastic insert; wherein the first liner is generally concave shaped wherein the second liner is generally flat; wherein the plastic insert spaces the second liner from the first liner; wherein when the second liner is expelled from the housing ahead of the first liner, the second liner forms a plate shaped projectile; wherein when the first liner is expelled from the housing, the first liner is deformed into a convex shaped projectile; wherein the plate shaped projectile clears a path through a barrier that protects a target, for the convex shaped projectile to impact the target unimpeded; and wherein the explosive charge uses a single detonator to produce two sequential projectiles. 2. The single stage kinetic energy warhead of claim 1,wherein the first liner comprises a first peripheral rim; wherein the second liner comprises a second peripheral rim; and wherein the first and second peripheral rims abut against an inner surface of the housing. 3. The single stage kinetic energy warhead of claim 1, wherein the plastic insert comprises a foam material.4. The single stage kinetic energy warhead of claim 1, further comprising a detonator assembly that initiates the explosive charge.5. The single stage kinetic energy warhead of claim 1, further comprising a back plate.6. The single stage kinetic energy warhead of claim 1, wherein the first liner and the second liner are coaxially aligned so that the first liner and the second liner follow substantially a similar flight trajectory when the first liner and the second liner are expelled from the housing.7. The single stage kinetic energy warhead of claim 3, wherein the plurality of first liners and the second liner are coaxially aligned so that the plurality of first liners and the second liner follow substantially a similar flight trajectory when the plurality of first liners and the second liner are expelled from the housing.
