Multiple Explosively Formed Penetrator (EFP) warhead

A warhead, comprising:

• a main charge;
• a liner on a top surface of the main charge;
• a plurality of booster charges spaced apart on a bottom surface of the main charge;
• and
• an initiation system configured for multi-point initiation of the plurality of booster charges to detonate the main charge to produce a plurality of detonation waves that constructively interfere at multiple locations on the back surface of the liner to cut the liner and to form and propel forward a plurality of explosively formed penetrators (EFPs), wherein a pressure at the multiple locations is at least 110% a detonation pressure at the front of the detonation waves between the locations.

A warhead, comprising:

• a main charge;
• a liner on a top surface of the main charge, wherein the liner includes a flat plate;
• a plurality of booster charges spaced apart on a bottom surface of the main charge;
• and
• an initiation system configured for multi-point initiation of the plurality of booster charges to detonate the main charge to produce a plurality of detonation waves that constructively interfere at multiple locations on the back surface of the liner to cut the liner and to form and propel forward a plurality of explosively formed penetrators (EFPs).

A warhead, comprising:

• a main charge;
• a liner on a top surface of the main charge, wherein the liner includes a plurality of dimples;
• a plurality of booster charges spaced apart on a bottom surface of the main charge;
• and
• an initiation system configured for multi-point initiation of the plurality of booster charges aligned to the centers of the dimples to detonate the main charge to produce a plurality of detonation waves that constructively interfere at multiple locations on the back surface of the liner to cut the each dimple and to form and propel forward a plurality of explosively formed penetrators (EFPs).

A warhead having a height H1 along an axis and a diameter D1, said warhead comprising:

• a main charge having a height H2;
• a liner on a top surface of the main charge, said liner having a plurality of dimples each having a diameter D2;
• a plurality of booster charges spaced apart on a bottom surface of the main charge and aligned to centers of the plurality of dimples;
• and
• an initiation system configured for multi-point initiation of the plurality of booster charges to detonate the main charge produce a plurality of detonation waves that constructively interfere at multiple locations on the back surface of the liner at the edges of the dimples to cut the liner and to form the dimples into a plurality of explosively formed penetrators (EFPs) that are propelled forward
• wherein 0.3<=H1/D1<=0.6, and
• wherein 0.5<=H2/D2<=1.5.

A warhead, comprising:

• a main charge;
• a liner on a top surface of the main charge;
• a plurality of booster charges spaced apart on a bottom surface of the main charge;
• and
• an initiation system including an inert housing having a single point initiation site and a plurality of tracks that connect the single point initiation site to the plurality of booster charges, explosive material in the plurality of tracks and a detonator at the single point initiation site, wherein initiation of the detonator produces detonation waves that travel through the explosive material in the tracks to initiate the plurality of booster charges to detonate the main charge and produce a plurality of detonation waves that constructively interfere at multiple locations on the back surface of the liner at a pressure between 110% and 200% of a detonation pressure of a single detonation wave to cut the liner and to form and propel forward a plurality of explosively formed penetrators (EFPs).
