A shot shell is disclosed. The shot shell includes a casing, a projectile, a cushion wad having a sabot, a propellant, and a primer for igniting the propellant. The projectile, the cushion and the propellant are contained within the casing. The projectile includes a reactive material pellet that is partially covered by a taper-shaped inert capsule.

A munition, such as a warhead, includes a penetrator casing for penetrating hard targets, such as a fortification or reinforced building or other structure. The penetrator casing has a relatively thick nose, and a relatively thin aft section extending back from the nose. A cable interface is in the aft section, and an electrical harness extends from the cable interface, external of the casing, and forward to a nose kit. The penetrator casing may have reduced-thickness portions, to provide weakness points to the casing that facilitate the casing being transformed into fragments of a semi-controlled and desirable size when an explosive within the casing is detonated after the penetration occurs, thus enhancing the effectiveness of the munition.

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 buoyant energy device is disclosed. Differing specific gravities between various materials are used to drive turbine blades to create energy by cycling the materials through a turbine activation area. The materials include water, oils, gasses (lighter than air and ambient air), or various other materials as circumstances may require. The device produces electricity that may be stored or used immediately. It is contemplated that the device could be used to power a missile, a torpedo, static mines, or the like.

Hardened target sensors and systems are described herein. An example system includes a projectile defining an ogive, a body, and a base. The body of the projectile is arranged between the ogive and the base. The system includes a sensor assembly including a nose member and a plurality of strain gauges. The nose member defines a nose portion, a shaft, portion, and a threaded portion. The strain gauges are attached to the shaft portion. The system includes a shroud member, which is mechanically coupled with the sensor assembly and the body. The system further includes a smart fuze arranged within the body. The smart fuze is operably coupled to the strain gauges. The strain gauges measure the compression/tension of the shaft portion, which is part of the nose member. The load measured by the strain gauges can be used to detect hardened target layers and/or voids.

A munition, such as a warhead, includes a penetrator casing for penetrating hard targets, such as a fortification or reinforced building or other structure. The penetrator casing has a relatively thick nose, and a relatively thin aft section extending back from the nose. A cable interface is in the aft section, and a electrical harness extends from the cable interface, external of the casing, and forward to a nose kit. The penetrator casing may have reduced-thickness portions, to provide weakness points to the casing that facilitate the casing being transformed into fragments of a semi-controlled and desirable size when an explosive within the casing is detonated after the penetration occurs, thus enhancing the effectiveness of the munition.

A munition may include a warhead, such as a penetrator warhead, enclosed in airframe. The airframe may enable connection to standard mountings, and/or to standard nose kits or tail kits. The airframe may have preformed fragments in it, packed between the airframe and the warhead. The preformed fragments may be loose, may be packed in a potting material, or may be in flexible bags. The fragments may enhance performance of the munition. The warhead may also contain preformed fragments.

A munition, such as a projectile formed of at least one reactive material. In one embodiment, the projectile includes a body portion formed of at least one reactive material composition wherein the at least one reactive material composition defines at least a portion of an exterior surface of the projectile. In other words, a portion of the reactive material may be left unbuffered or exposed to the barrel of a gun or weapon from which it is launched and similarly exposed to a target with which the projectile subsequently impacts. In one embodiment, the projectile may be formed with a jacket surrounding a portion of the reactive material to provide additional structural integrity. The projectile may be formed by casting or pressing the reactive material into a desired shape, or the reactive material may be extruded into a near-net shape and then machined into the desired shape.

The present invention relates to warheads with blast wave conditioners and in particular to devices for quickly removing a door to permit entry through the doorway. It discloses a device and method of shaping the pressure wave pattern by the use of inert material. The inert material of the present invention is used to reduce localized directional effects occurring at the point of impact, instead generating a more diffuse pressure-wave pattern across the target surface.
