Abstract: A projectile fuze detects transitions between target layers by an electronic antenna radiating laterally into the target material and coupled to a pullable oscillator whose frequency shifts as the target material changes while the projectile penetrates. A frequency shift threshold detector relates the observed frequency shifts to a stored target profile to detonate the projectile after the desired layer penetration.

Abstract: A projectile includes an explosive charge, a corresponding initiating device, a penetrator that only deforms upon impact with a target having a predetermined mechanical resistance, an internal impact contactor arranged between the penetrator and the charge, and a device to ensure initiation of the charge following crushing of the internal impact contactor and after the explosive charge has begun to be deformed following impact on the target. The projectile is particularly effective against hard targets such as stone, brick or cement structures.

Abstract: A submunition has a metallic body 1 a sensor 4 for sensing the presence of metal and an extendable probe (e.g. a spring 3) separating the sensor 4 and body 1 to avoid interference with the sensor. A circuit including the metal sensor and an impact sensor detonates the submunition if impact with a metal body is detected; if impact only is detected the submunition adopts the role of a mine.

Abstract: A projectile with a tandem charge consisting of a borehole charge and a secondary firing charge, in which exact piercing guidance between the borehole charge and the secondary firing charge is obtained by the counterdirectional motion of the housing part with the secondary firing charge relative to a tubular guiding part of the housing.

Abstract: An article of submunition, having a housing on which there is arranged an outwardly extendable distance feeler or spacer support. A head on the support carries a sensor which is connected through the intermediary of a connector cable to an evaluating circuit which is arranged within the housing. The connector cable is formed as a ribbon-shaped or flat cable which is constituted of plastic material, in which the flat cable is bifilarly or double wound into a spiral, wherein the winding axis lies transversely of the longitudinal direction of the flat cable, in which the spiral of the flat cable has its shape stabilized through a thermal treatment, and in which the spiral is located adjacent the distance feeler support.

Abstract: A telescopic warhead for a submunition ejectable from a carrier projectile the explosive charge of which is made up of submunitions scatterable and housed in the front portion of the carrier projectile, characterized in that the telescopic head includes a telescopic sliding skirt formed of a plurality of cylindrical elements, which are preferably metallic. The telescopic warhead, during storage, does not reduce the inside space requirement of the carrier projectile which leaves the inner volume available in front of the explosive charge whether the telescopic warhead is in a storage configuration or in an expanded configuration.

Abstract: The invention relates to a mine or drop bomb having an effective load, a shaped charge, and an antenna which encompasses a target recognition device. In order to achieve on the one hand a rugged, arrangement which can withstand high acceleration forces, and, on the other hand, provide an optimum functioning of the antenna, the antenna is axially outwardly slidable, so that it can move from an inoperative, respectively transport, position into an operative position. For this purpose the antenna is mounted on a plurality of columns, which are equi-angularly disposed about the periphery of the arrangement and are slidable within guide means disposed in the housing of the arrangement. The antenna may be deployed by an inflatable gaseous container. In one embodiment the container may comprise an explosive gaseous mixture which ignites to break-off the antenna from the device before the mine explodes.

Abstract: This invention provides a subcaliber projectile which is launched from a full bore projectile having a shaped charge warhead prior to impact with the target. The subcaliber projectile is tethered to the full bore projectile by means of a fine electrical cable of fixed length which serves as the communication link between the two projectiles with the length of the cable determining the fuzing standoff distance. The ballistic coefficient of the subcaliber projectile is made such that the subcaliber projectile always flies ahead of the full bore projectile.

Abstract: The invention features use of a probe that is flexible until after the munition is projected, so that it may be folded up and compactly stored despite considerable length, but is fairly rigid as the munition descends toward earth, and cooperates with other mechanism to explode the munition when the end of the probe engages an obstruction such as the ground.
