According to an aspect of the invention, there is provided a method of triggering an explosive charge of each of a plurality of munitions, the method comprising: launching a first munition, into the air, from a first gun barrel, and into water to engage with a target location, the first munition comprising a first explosive charge and a first fuze system, adapted to trigger the first explosive charge in the water, launching a second munition, into the air, from a second gun barrel, and into water to engage with the target location, the second munition comprising an second explosive charge and a second fuze system, adapted to trigger the second explosive charge in the water, the method comprising co-ordinating the timing of the triggering of the first explosive charge and the second explosive charge to establish a co-ordinated explosive event at the target location.

An anti-personnel autonomous vehicle (APAV) system has a fuselage formed by a directional fragmentation weapon (DFW). An unmanned aerial vehicle (UAV) assembly is engaged to the DFW, the UAV assembly having a plurality of lift units positioned to provide balanced lift on the DFW. A control module integrated in the UAV assembly has a wireless transmitter/receiver communicating with a remote controller.

Disclosed are an airburst munition and an airburst signal transfer device. By simply signaling information regarding a distance to an explosion location of the airburst munition to an explosion control system inside the airburst munition while the airburst munition passes through a tubular body of the airburst signal transfer device, it is possible to easily, simply, and automatically enter the information regarding the distance to the explosion location of the airburst munition to the airburst munition using the airburst signal transfer device.

A method, a device, and a system using the device, for avalanche control using an unmanned aerial vehicle to transport an explosive charge to a snow surface or snowpack. A holder of the device holds the explosive charge in a container. A receiver of the device receives a release signal. The holder releases the explosive charge in response to the release signal. A coupler couples the holder to the unmanned aerial vehicle. The explosive charge is fuzed to detonate after release from the holder to trigger an avalanche.

A crowd control projectile includes a payload carrier, an incapacitating agent inside the payload carrier, and an activating mechanism for activating the incapacitating agent. The activating mechanism includes a sensor and a timer. The timer delays the activation until a predetermined delay after the sensor senses that the projectile has been launched. Alternatively, the activating mechanism includes a receiver for receiving an activation signal after the projectile has been launched. Preferably, the projectile has the shape of a clay pigeon. A launcher of such a projectile includes a communication mechanism for transmitting a timing signal or an activation signal to the projectile and an arm for launching the projectile by direct contact. To control a crowd, the projectile is launched over the crowd by direct contact with a solid arm and the activating mechanism is used to activate the incapacitating agent when the projectile is above the crowd.

A fuze for an airburst munition determines a corrected muzzle velocity via an on board acceleration sensor and processor and corrects an airburst time, accordingly. Velocity calculations are made in real time which allows for timely update of airburst time thereby preventing error stack up due to muzzle velocity variations.

A fragmentation warhead is provided, capable of being mounted in a carrier vehicle, the warhead having a longitudinal axis. In at least one example the warhead includes a shell that extends along the longitudinal axis. The shell includes a fixed shell portion and a fragmentation portion, and defines therebetween a cavity for accommodating therein an explosive charge. The fragmentation portion includes at least one set of serially adjacent fragments in correspondingly serially contiguous relationship in the fragmentation portion and in generally helical relationship with respect to the longitudinal axis. A corresponding carrier vehicle and a corresponding missile are also provided.

An airburst delivery system that may provide for effective delivery of firefighting material to forest fires. The system generally utilizes an explosive charge to detonate a frangible containment vessel filled with firefighting material above the earth and typically above fire in a forest canopy. The resulting expanding sphere of water and related shockwaves provides a multi-effect interaction with the fire resulting in multiple water soakings combined with the sue of the vacuum and compression created by the shockwave to starve the fire of fuel and oxygen.

A projectile round for intercepting an incoming threat to a vehicle or the like is provided. The projectile round may include an explosive layer, which upon detonation, may cause a the fracturing of one or more material layers into one or both of shrapnel and chaff while simultaneously causing the distortion and/or destruction of a piezoelectric material contained within the projectile round. The distortion and/or destruction of this piezoelectric material may further cause the release of an electromagnetic pulse. The projectile round may be part of a countermeasure system against guided munition threats, including those posed by man-portable air defense systems.
