Disclosed herein is a grenade with a plurality of independently detachable carpel segments each containing a charge and independently detonated from other carpel segments. The grenade may include a head section with a triggering mechanism, and a modular hollow core with a rod having an upward mechanical bias towards the head section, which may include a safety pin, lever, and pivot. When the pin is pulled, a lever can be released after timed delay, and the release of the lever allows the rod to advance upward, which triggers strike pins that strike a primer which ignites a propellent that ejects a carpel segment from the core. The propellent simultaneously ignites a fuse in the body of the carpel segment, and the fuse triggers a detonation of the main charge in the carpel. Timed delays on the fuse can be used to cause the carpel segments to detonate at different times.

Provided is a frangible munitions device optimized for a dome and cylinder that yields fragments having shapes corresponding to a predetermined embossment pattern upon explosive rupture. The embossment pattern includes a first set of inner regular hexagonal embossments formed into the dome and cylinder that are aligned with the axis of the cylinder, and a second set of outer pre-deformed hexagonal shapes that distort to produce regular hexagonal shapes after drawing into the cylinder wall. The second set of shapes are separated by sharp transition regions. The shapes are embossed in a repeated pattern around the hollow cylinder and the dome top. The dome yields a plurality of fragments having shapes corresponding to the first set of inner regular hexagonal embossments upon explosive rupture, while the cylinder yields a plurality of fragments having shapes corresponding to the second set of outer pre-deformed hexagonal embossments upon explosive rupture.

A small-caliber ammunition is disclosed. The small-caliber ammunition includes a casing and a frangible projectile located within the casing. The frangible projectile includes a metal inert capsule and a reactive material (RM) pellet embedded within the metal inert capsule. The top surface of the RM pellet flushes with the top surface of the metal inert capsule. The casing contains a smokeless propellant and a primer for igniting the smokeless propellant.

A munition includes a warhead having a warhead axis and axially opposed first and second warhead ends. The warhead includes: a tubular shock attenuation barrier including an axially extending passage extending from a first barrier end proximate the first warhead end to a second barrier end proximate the second warhead end; an explosive core charge disposed in the passage; an explosive main charge surrounding the shock attenuation barrier; projectiles surrounding the main charge; a core charge detonator; and a main charge detonator. The warhead is configured to be activated in each of a first projection mode and an alternative second projection mode. When the warhead is activated in the first projection mode, the main charge detonator detonates the main charge to thereby forcibly project the projectiles from the warhead with a first set of projection velocities and velocity profile. When the warhead is activated in the second projection mode, the core charge detonator detonates the core charge proximate the first barrier end such that a core charge detonation wave propagates through the passage to the second barrier end and, at the second barrier end, the core charge detonation wave detonates the main charge to thereby forcibly project the projectiles from the warhead with a second set of projection velocities and velocity profile. The second set of projectile velocities and velocity profile is different from the first set of projectile velocities and velocity profile.

A damage matrix generating device is proposed. The damage matrix may include a memory and a processor configured to control the memory. The processor may acquire warhead fragment data obtained by classifying mass and number of fragments scattering in given directions as a warhead is detonated, and target vulnerable area data obtained by classifying a vulnerable area according to an encounter relationship between a fragment and a target. The processor may also generate a virtual target based on an approach direction of the fragment to each of the grids, the grids dividing a ground plane. The processor may further generate a damage matrix by extracting encounter information of fragments to meet the virtual target as the fragments scatter in the given directions based on the warhead fragment data and calculating a damage probability for each ground location according to the encounter information based on the target vulnerable area data.

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.
