A method is provided for calculating the bursting point of at least one projectile fired at a target object, involving measuring the position of the projectile, estimating the position of the projectile, estimating the speed of the projectile, measuring the position of the target object, estimating the position of the target object, estimating the speed of the target object, calculating optimal bursting points for the projectile based on the estimated position of the projectile, the estimated speed of the projectile, the estimated position of the target object and the estimated speed of the target object, and communicating the bursting points for the projectile to the projectile. A computer program, a computer system, and a weapons system are also provided.

A digitally controlled hand-tossable explosive delivery receptacle comprises a ruggedized reusable compartment enclosing a digital circuit and a disposable cartridge holding one or more explosive chemical agents and a primer. The disposable cartridge is configured to be mounted to the ruggedized reusable cartridge, and a high-strength bulkhead incorporated into the reusable or disposable compartment that separates the digital circuit from the chemical agents. The reusable compartment is sufficiently ruggedized to withstand the ignition of the primer and the detonation of the chemical agents to be reused with one or more additional disposable cartridges. In one implementation, the delivery receptacle uses a commercial airbag initiator as the primer, which is arranged in relation to the one or more chemical agents so that when the initiator is activated, it generates a pressure wave that expels the one or more chemical agents from the grenade.

A lethal projectile for immobilizing a target is capable of self-separating or otherwise opening after launch by a launcher and may release a payload prior to impact with a target. Opening may caused after an energy storage means of the projectile is charged beyond a threshold energy level. Charging of the energy storage means may be accomplished through dynamic induction when the projectile moves through a stationary magnetic field generated by a magnet of the launcher prior to launch, A control circuit can increase or decrease the magnetic field strength of the magnetic field in order to control the distance at which the projectile releases its payload, A rangefinder may provide distance information to the control circuit for charging the energy storage means to a specific energy level associated with the distance to a target.

A multi-mode fuse system for use in a warhead for combating a target. At least one target sensor is electrically connected to a signal processing block and an I/O-block. The I/O-block is configured to be set by the operator of the warhead. The target sensor is adapted to generate an electrical output in response to the rate of deceleration of the warhead. The fuse system is adapted to discriminate the hardness of the target based upon the electrical output of the target sensor and to select the mode of operation depending upon the target discrimination. The fuse system is adapted to discriminate at least one type of target depending upon the electrical output of the target sensors. The fuse system selects one of at least three modes of operation of the warhead. Also a method for classifying the target hardness and selection of the operational mode of a warhead.

The system and method for accurately determining range-to-go for the command detonation of a projectile. Using dual laser and/or radio frequency detectors on the tail and on the nose of a spinning projectile to determine the range-to-go, time-to-go, or lateral offset from the projectile to the target.

A pyrotechnic projectile, an electronic controller for a pyrotechnic projectile, and a method of controlling a pyrotechnic projectile are provided. The pyrotechnic projectile comprises: a burst charge, configured to provide an a visual and/or audible effect upon activation thereof; an electronic match configured to activate the burst charge; and an electronic controller, coupled to the electronic match. The electronic controller is configured to determine an altitude of the pyrotechnic projectile and cause the electronic match to activate the burst charge at least in part according to the altitude of the pyrotechnic projectile.

An ignition safety device (ISD) used in an ignition system of a missile is configured to selectively control the ignition of two or more pulses or stages of a rocket motor propulsion system, based on a flight profile mode selection of a flight velocity mode, in which the missile is configured to travel at an optimized flight velocity, or a flight distance mode, in which the missile is configured to travel an optimized flight distance. The ISD is configured to selectively ignite the pulses or stages substantially simultaneously upon selection of the flight velocity mode, or in a delayed sequential manner upon selection of the flight distance mode. The ISD is also configured to selectively inhibit the delayed sequential ignition of the pulses or stages in the event of incidental ground or water impact of the missile after ignition of the primary pulse or stage.

A launcher and projectile system include at least one magnet disposed on or within the launcher for charging a wire coil of the projectile to energize the projectile, thereafter having a housing of the projectile rupture, disintegrate, separate or otherwise have an opening created therein after launch to release a payload. In another embodiment, an accessory for a launcher and projectile is provided, the accessory comprising a magnet for charging a projectile that is launched by the launcher. The strength of magnetic field of the magnet may be adjusted for selective performance of the projectile.

The invention relates to a test and/or practice ammunition having at least one projectile with a projectile head and a fin which can be found at the end of the projectile for example or a projectile with a projectile base and a projectile ogive. A cartridge shell is used to receive a drive and has a shell base, wherein an interface is attached in or on the shell base. The test and/or practice ammunition is characterized by a programmable fuze which is arranged in the projectile head or the projectile ogive. The projectile head/projectile ogive is equipped with at least one fuze amplifier and an electronic fuze system and optionally a separating charge.
