According to a first aspect of the present invention, there is provided a munition assembly, arranged to be launched from a gun, the assembly comprising: a carrier for a submunition, the carrier comprising a cavity in which the submunition is located; and a submunition, carried by the carrier in the cavity, the submunition arranged to be controllably expelled from the carrier; the submunition comprising: a submunition explosive charge; and a submunition fuze, wherein: the munition assembly is adapted to be launched, into the air, from a gun barrel, where the submunition is then arranged to be controllably expelled from the carrier and enter a body of water; and the submunition fuze is adapted to trigger the submunition explosive charge under water.

The invention relates to a percussion fuse having an active sensor, which generates a sensor voltage, having a filter circuit consisting of a high pass and at least one low pass, in order to be able to adjust dynamic percussion characteristics. The invention further relates to an operating state switch, which can transition the percussion fuse into one of two operating states, specifically into an activated and a deactivated operating state. To this end, the operating state switch is switched into one of the two operating states by means of a safety voltage. In the active operating state, the sensor voltage is supplied directly to the threshold value switch and in the deactivated operating state, the sensor voltage is held below the threshold value of the threshold value switch by an input limiter.

An ordnance for air-borne delivery to a target under remotely controlled in-flight navigation. In one embodiment, self-powered aerial ordnance includes upper and lower cases. A plurality of co-axial, deployable blades is powered by a motor positioned in the upper case. When deployed, the blades are rotatable about the upper case to impart thrust and bring the vehicle to a first altitude above a target position. An explosive material and a camera are positioned in a lower case which is attached to the upper case. The camera generates a view along the ground plane and above the target when the ordinance is in flight. When the vehicle is deployed it is remotely controllable to deliver the vehicle to the target to detonate the explosive at the target. The ordnance may drop directly on a target as a bomb does.

The disclosure describes, in various example embodiments, a small arms or firearm projectile including a shell and a hemostatic material retained within the shell. The hemostatic material has a mechanical modulus above 25,000 Pa. In some embodiments, the shell includes a plurality of perforations. In some embodiments, the plurality of perforations are configured to provide, upon an impact of the projectile, fluid communication between the hemostatic material and the exterior of the shell via the plurality of perforations. In some embodiments, the hemostatic material includes a polymer core configured to provide a scaffold for inducing hemostasis in a local wound volume. In some embodiments, the projectile includes a contrasting agent. In some embodiments, the projectile includes a lubricating agent retained in the interior of the shell. In some embodiments, the projectile further includes 0.5 to 3 grains of Kaolin retained in the interior of the shell.

A projectile includes a bag of gaseous medium to effectively retard the velocity thereof on impact with a target in such a way as to prevent excess damage, injury or penetration, wherein the bag is configured to increase in area at the nose of the projectile following impact with a target, wherein the projectile includes a needle for penetrating a target and a cap which encloses the bag and includes a flat forward-most surface.

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.
