Abstract: 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.

Abstract: A cartridge that generates higher than typical chamber pressures has an enhanced means of primer retention for retaining the primer in the primer recess of the casing. The means may be a lip folded onto a conical surface, a annular groove to receive deformed primer wall portion material upon detonation, a concavity in the rearward facing wall of the primer, a check valve in the flash tube to inhibit propellant gases from reaching the primer recess, or specifically configured primers with a greater length than diameter and with greater wall thicknesses.

Abstract: A preformed warhead is provided with a casing having a front section and a rear section. A plurality of target piercing fragments is arranged at the front section. The density of a given fragment diminishes the further the given fragment is from a centerline of the warhead. An initiating point located on the centerline is positioned at the rear section of the warhead. An explosive charge is positioned between the initiating point and the target piercing fragments. Upon detonation of the warhead, the explosive wave propagates in a radial fashion such that the fragments receiving the impact of the explosive force soonest and most directly are those fragments closest to the centerline. Thus, a substantially planar velocity profile of all the fragments is achieved.

Abstract: A wall breaching explosive fragmentation ammunition having a tungsten alloy nose cap with ceramic cone nose which make possible penetration into a hardened target with survivability of the warhead. The ammunition employs a unitary construction with fuze completely within the projectile's shell case. The ammunition has an external plastic rotating band which also encloses an induction antenna. The antenna may signal the fuze on a wire, through a hole in the shell case. The fuze signals may be fed through a gun barrel, then picked up on the antenna. The ammunition also employs a controlled pattern fragmentation mechanism incorporating a patterned plastic liner.

Abstract: An artillery projectile for firing from an artillery gun, mortar or artillery rocket launcher. The artillery projectile includes a body, a payload with a number of inert fragments located within the body, a booster motor associated with the body for accelerating the body with the payload to a penetration velocity, and an opening arrangement associated with the body and deployed for initiating release of the fragments. The artillery projectile further includes a control system causally associated with the booster motor and the opening arrangement. The control system is configured to generate a first command to actuate the booster motor and a second command to actuate the opening arrangement.

Abstract: Some embodiments pertain to a projectile that includes a propellant and a casing that encloses the propellant such that the casing acts as a reaction chamber during flight of the projectile. The casing includes a plurality of flechettes. When the projectile strikes (or is near) a target, a large internal sheer pressure forms within the casing. This sheer pressure causes the flechettes to sheer apart at the thinnest sections of the casing. Once the thin sections of the casing are sheered apart, the flechettes will be unconstrained such that the flechettes take individual flight paths.

Abstract: The dynamically configurable controlled fragmentation insert mechanism of this invention includes an assembly of three or more sleeves with differing through hole patterns thereon, that fit inside the shell casing. The individual sleeves can move independently of one another and a simple pinning mechanism holds the parts in place for a selected configuration. The warfighter can realign the insert sleeves by to create different geometric patterns of holes, each designed to engage a different target set with optimally sized fragments. The aligned patterns of holes creates individual geometric shapes that focus high-velocity jets to cut into the steel shell casing to correlate to the through-holes in the aligned patterned sleeves. Realigning the insert sleeves changes the through-hole pattern to produce different fragment sizes and mass distributions.

The inner core explosive material has a heat of combustion comprising about 16 kcal/cc or higher and the outer annulus of explosive material has a heat of detonation comprising about 2.1 kcal/cc or higher. A warhead casing surrounds the outer annulus of material. The warhead has a dual initiation system. The first initiation system comprises a detonation cord that extends substantially through the inner core of explosive material and has an initiator at the tope side. The second initiation system comprises a booster explosive that contacts the bottom side of the outer annulus of explosive material and an initiator proximate to the booster.

Abstract: An ammunition device (4) comprising one or more warhead effect jackets (17), each jacket containing warhead effect elements (18). The ammunition device also incorporates one or more explosive compositions arranged inside each warhead effect jacket that in or close to the target is/are triggerable by means of a triggering device. One or more separation charges is/are arranged adjacent to each warhead effect jacket that when actuated cause removel of one or more said warhead effect jacket(s). The actuation devices incorporate or interact with a programming device that operates with a first mode that can be an initial mode in which the actuation devices remain non-actuated, and a second mode in which the programming device actuates the actuation devices for initiating the separation charges, thereby causing ejection of each warhead effect jacket concerned.

Abstract: The present invention comprises a warhead designed to provide a number of spiraling tendrils composed of segmented rods that move in an increasing radial arc in order to defeat a target. The warhead comprises a substantially cylindrical explosive charge having a plurality of rod segments arranged circumferentially around the explosive charge in a plurality of horizontal layers. As the horizontal layers descend down the explosive charge, the rod segments are offset from those directly above and below them to create a pattern that appears to be twisted columns. The number of columns is equivalent to the number of rod segments in each horizontal layer.

Abstract: An improved method of producing a controlled fragmentation warhead case by mbedding an expanded metal liner on the interior surface of a casing for a warhead or other ordnance device. The process of embedding an expanded metal liner into the casing during the forming of the casing produces a controlled fragmentation grid on the interior surface of the casing. The improved method of producing a controlled fragmentation warhead case is particularly suitable for weapon systems employing large, unitary warheads.

Abstract: The fragmentation casing has a one-piece hollow body (1) that incorporates nominal break points; this hollow body (1) is divided at least in one section (4) by at least one separating cut (5) that forms a separating gap. The separating cut is so made that the hollow body remains in the form of a one-piece structure. The surfaces of the separating cut that are adjacent in the separating gap are brought into contact with each other and are so fixed in contact with each other.

Abstract: A multi-purpose bomblet is designed for accomplishing various military mions. A standoff spike and shaped charged are provided for piercing heavy armor and a fragmentation case surrounds the shaped charge. Upon detonation of the shaped charge, the fragmentation case disintegrates to provide shrapnel which is effective against personnel. An inner liner of incendiary material also surrounds the shaped charge and, upon detonation of the shaped charge, the incendiary material is ignited and dispersed and is useful for starting fires.

Abstract: An explosive fragmentation device such as a grenade or a mortar bomb has a casing formed from flat sided notched wire formed into a coil. Instead of coiling the wire so that sides of the coiled wire which are adjacent after coiling lie normal to the longitudinal axis of the coil, as in a known form of grenade body, the wire is given additionally a twist about its own longitudinal axis during coiling, so that the adjacent flat faces of adjacent turns are substantially normal to the surface of the finished casing. In this way adjacent turns overlay one another, preferably completely, and the outer surface of the casing can then be smooth. Also, adjacent turns can then be bonded together as by brazing or soldering, which is impractical with coiling "normal to the axis". This means explosive cannot be trapped between adjacent turns to be accidentally detonated, an outer casing is unnecessary, and the casing is stronger.
