A munition includes a triply periodic minimal surface (TPMS) structure attached to an inner surface of a cylindrical tube. The TPMS structure is formed by an additive manufacturing process to promote fluid permeability and to reduce pressure drop to prevent trapped air and maximize surface area contact at a structure and liquid interface. An explosive material is introduced into one or more upper apertures of the TPMS in a flowable state to fill the TPMS structure n a compartmentalized arrangement that provides stiffness to the munition.

An explosive system and corresponding method employ a number of explosive portions, each of sub-critical dimensions so that initiation of the portion would result in incomplete detonation. A selectively-deployable spacer arrangement or deployment mechanism is deployed between a storage state in which gaps or misalignments are maintained between the explosive portions so that the explosive system remains undetonatable, and a detonable state in which the portions are brought together sufficiently to function as a combined explosive charge having effective dimensions larger than critical dimensions, rendering the explosive system detonatable.

An ammunition round comprises an optimized projectile incorporating a hardened penetrator and an explosive self-destruct mechanism for a medium caliber high rate of fire round. The ammunition round incorporates a hardened segment penetrator followed by a pyrotechnically initiated high explosive warhead that substantially increases the effective range and terminal performance against RAM targets. The hardened segment penetrator localizes the kinetic energy of the projectile to increase target penetration prior to the initiation of the high explosive warhead.

A method for neutralizing a threat, include: detecting an oncoming object prima facie aimed at a protected platform. In response to the detecting, classifying the object as an Anti-Tank-Guided Missile (ATGM) threat. In response to said classification, calculating fire characteristics of the interceptor, such that the ATGM threat will fall an Electro-Magnetic-Pulse induced neutralization geometric envelope relative to the interceptor, for achieving a neutralization effect of the threat, and firing said interceptor that is equipped with at least an Electro-Magnetic-Pulse warhead according to the fire characteristics.

A warhead having a circumference, a radial direction and a longitudinal direction and comprising radially extending trapezoids. Each trapezoid having a length into said longitudinal direction and a plurality of said trapezoids extending around said circumference.

A warhead includes a casing having a removable front portion, a plurality of explosive segments positioned in the casing, a plurality of spacers positioned in the casing and separating the plurality of explosive segments from each other, and a removable piston configured to be inserted inside the removable front portion of the casing, wherein the removable piston pushes against the plurality of explosive segments to create a continuous segment. The removable piston may push against the plurality of explosive segments to close the plurality of spacers and move the warhead from an off position to an on position. The continuous segment may be above an explosive failure thickness in the on position. The continuous segment may be configured to detonate upon reaching the failure thickness.

A multi-warhead munition includes a first cylindrical warhead having a cavity filled with high explosive, and a second cylindrical warhead offset axially from the first cylindrical warhead. The second cylindrical warhead is a transformable, segmented warhead including a plurality of segments each having an outer segment face bounding a cavity of the segment filled with high explosive. The segments are elongated and mounted at one end for rotation away from an axis of the munition to an open position in which the segment faces are pointed in a forward direction for detonation. Rotation may generally be somewhere in a broad range from about 105 degrees to about 170 degrees, obtaining different effects in different sub-ranges. The munition includes first and second detonators for the first and second cylindrical warheads respectively, the second detonator simultaneously detonating the segments of the second cylindrical warhead.

A munition includes a composite case, a blast cone housed by the composite case, a grenade aft of the blast cone and housed by the composite case, a first attenuator forward of the blast cone, and a second attenuator aft of the blast cone and forward of the grenade.
