A penetrator for a projectile with a tail assembly, wherein the penetrator includes at least one outer body that acts in a terminal ballistic manner for attacking an armored target, in particular a battle tank with reactive armor. The cross-section of the outer body perpendicular to a longitudinal axis of the outer body is a hollow cross-section. The hollow cross-section of the outer body has an area, and an area moment of inertia of the hollow cross-section is increased in comparison with a solid cross-section of at least equal area, so that the outer body has an increased bending stiffness on account of the increased area moment of inertia.

A compressive structural element including: an enclosure having a top, a bottom, and inner wall and an outer wall, a first cavity defined between the inner and outer walls and a second cavity defined by the inner wall; and a non-compressible material disposed in the first cavity; wherein the outer wall has at least a portion thereof inwardly shaped toward the first cavity and the inner wall has at least a portion outwardly shaped towards the first cavity such that a first compressive force acting on the top and/or bottom tending to compress the element by a first deflection causes an amplified second deflection, relative to the first deflection, of the inner and/or outer walls into the non-compressible material, thereby exerting a second compressive force against the non-compressible material, resulting in a resistance to the first deflection and the first compressive force tending to compress the element.

According to a first aspect of the present invention, there is provided a reconnaissance and communication assembly, adapted to be launched from a gun barrel into the air. The assembly comprises a carrier (with a cavity) and a payload (within the cavity). The payload is arranged to be controllably expelled from the carrier and once expelled from the carrier, the payload transmits a signal.

A projectile includes a hollow body carrying a payload formed of inert sub-projectiles that can be dispersed on trajectory contained in a cup including a piston closing one of its ends, the body at its rear part with a base housing a pyrotechnic charge separated from the sub-projectiles by the piston, which can translate with respect to the body of the projectile to push the cup and the sub-projectiles axially out of the body. The cup is formed of independent sectors. The piston is secured to the sectors when contained in the body and the cup is secured to the body by a connecting apparatus weakened to break under the force of the piston pushed by the gases generated by the pyrotechnic charge. An ogive is secured to the cup by a securing apparatus that is coaxial with the longitudinal axis of the projectile and locked by the sectors.

An electronics ordnance delivery system includes an electronics component that is to be delivered into a target. The electronics component is enveloped by a protective housing that assists in the delivery of the electronics component payload. The protective housing is made of an electronically-conductive material such that it can function as an antenna for the transmission of signals by a transmitter component of the electronics component.

The invention relates to a common carrier munition ammunition device, more particularly to common carrier payload delivery shell. There is provided a common carrier munition comprising a tail unit, a main body which comprises a payload cavity for receiving a payload, a fuze, and located between said main body and the fuze an ogive element, wherein the tail unit and main body comprise cooperatively engaging male and female threaded portions, wherein at least one of the threads is a shearable thread.
