In a MEFP warhead detonation of the main charge is controlled to provide elevated pressure at multiple locations on the back surface of the liner to cut the liner and to form and propel forward a plurality of EFPs. An initiation system is configured for multi-point initiation of a 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 form pressure hot spots that cut the liner and to form and propel forward a plurality of EFPs. In different embodiments, the elevated pressures are between 110% and 200% of the detonation pressure at the front of an individual detonation wave. The liner may, for example, be a flat plate or a include a plurality of dimples in which case the boosters are aligned to the center of the dimples.

A warhead includes a casing having a periphery wall that extends along a central axis from a forward end of the casing to a rearward end of the casing. The casing defines a cavity configured to contain an explosive material, wherein the forward end of the casing includes a first thread pattern configured to engage a guidance system casing, and the rearward end of the casing includes a second thread pattern configured to engage a propulsion system casing. A first row of fragments is arranged along a first section of the periphery wall of the casing. A plurality of second rows of fragments is rearward of the first row of fragments and arranged along a second section of the periphery wall of the casing. In an example, each of the first and second sections tapers inward towards the central axis as it extends toward the forward end of the casing.

In a MSCJ warhead detonation of the main charge is controlled to provide elevated pressure at multiple locations on the back surface of the liner to cut the liner and to form and propel forward a plurality of SCJs. An initiation system is configured for multi-point initiation of a 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 form pressure hot spots that cut the liner and to form and propel forward a plurality of SCJs. In different embodiments, the elevated pressures are between 110% and 200% of the detonation pressure at the front of an individual detonation wave. The liner may, for example, include a plurality of recesses such as shallow dimples or deeper conical structures in which case the boosters are aligned to the center of the recessed structures.
