The present invention provides an ammunition disabler with a material capable of being selectively changed in response to an energy wave for preemptively disabling ammunition. In at least one embodiment, the ammunition disabler includes a material selectively structurally changeable from an operative state to a deactivated state upon exposure to an energy wave is provided, where the material is positioned at least partially between the firing pin and the priming compound when the ammunition is chambered within the firearm (with the priming compound positioned between the material and the propellant), and related systems, methods and uses. The material may be contained within the primer cup with the priming compound. The material may be positioned adjacent to the priming compound in direct or indirect contact or in close proximity. The material may be positioned externally from the primer cup.

A detonator arrangement (10) comprising a detonator (1) having an initiation charge (2) and a base charge (3), which initiation charge (2) is arranged to initiate a detonation of said base charge (3), characterized in that the said detonator arrangement (10) comprises a securement device (5, 72, 64) movable in relation to the detonator (1), which securement device (5, 72, 64) can be disposed in a first position arranged to prevent a transfer of the detonation of the initiation charge (2) to the base charge (3), whereby the detonation of the base charge is avoided, and in a second position arranged to allow the transfer of the detonation of the initiation charge (2) to the base charge (3), whereby the detonation of the base charge is obtained.

A closed, self-contained ballistic apogee detection module for use in a projectile, such as a rocket, mortar round, or artillery round, fuses data from multiple built-in sensors, such as an accelerometer, a magnetometer, and a gyroscope, and processes the data using a microprocessor through a custom quaternion extended Kalman filter to provide accurate state and orientation information about the projectile so as to accurately predict apogee. The module outputs a signal indicating apogee detection or prediction which they projectile uses to initiate fuze arming, targeting control, airbody transformation, maneuvering, flow effector deployment or activation, payload exposure or deployment, and/or other mission activity. Because the system and method of the invention does not rely on external environmental data to detect apogee, it need not use a pressure sensor and can be completely sealed in and closed without requiring access to air from outside the projectile for barometric readings.

A warhead includes a casing having a removable front portion, a plurality of explosive segments positioned in the casing, a plurality of spacers positioned in the casing and separating the plurality of explosive segments from each other, and a removable piston configured to be inserted inside the removable front portion of the casing, wherein the removable piston pushes against the plurality of explosive segments to create a continuous segment. The removable piston may push against the plurality of explosive segments to close the plurality of spacers and move the warhead from an off position to an on position. The continuous segment may be above an explosive failure thickness in the on position. The continuous segment may be configured to detonate upon reaching the failure thickness.

An arrangement has an opto-pyrotechnic initiator, at least one laser, and an optical fibre, via which the laser radiation of the laser is guided to the opto-pyrotechnic initiator. Also disclosed is a method for improving the safety of such an opto-pyrotechnic initiator. At least one optical filter element having power-dependent or intensity-dependent transmission or reflection is arranged in the beam path of the laser radiation between the laser and the initiating impingement location of the laser radiation in the initiator. The filter element and the beam guidance for the laser radiation are selected such that for a laser power of the laser, that is intended to effect an initiation, the filter element has a higher transmission or reflection or can be switched to a higher transmission or reflection than for a lower laser power by application of an optical or electronic signal that is independent of the laser radiation.

A mechanical self-percussion fuze for a non-gyrating ammunition includes a firing pin disposed along a central axis and a primer provided in a primer holder. The primer holder is movable about an axis of rotation that is parallel and off-centered with respect to the central axis between a storage position in which the primer is off-centered with respect to the firing pin and an armed position in which the primer is aligned with the firing pin and safety devices coupled to the primer holder in order to keep the fuze in a safe state until at least two mutually independent physical phenomena linked to the firing of the ammunition occur. The fuze has a wind turbine designed to be driven in rotation by the relative movement of the air during the flight of the ammunition and to transmit this rotational movement to the primer holder only after the safety devices have been removed.

An explosive device composed of: a flux compression generator operative to produce a high intensity electric current when activated; and an electrical payload connected to the generator and constructed to receive the high intensity electric current and cause energy in the current to generate a plate or shaped projectile in the payload and to launch the projectiles into an explosive or insensitive reactive material target for the purpose of initiating the reactive material at single or multiple points.

The invention relates to a mechanical self-percussion fuze (1) for a non-spinning round, having a firing pin (14) disposed along a central axis (A), a primer (17) provided in a primer holder (17) that is movable about an axis of rotation (B) that is parallel and off-centre with respect to the central axis (A) between a storage position in which the primer (17) is off-centre with respect to the firing pin (14) and an armed position in which the primer (17) is aligned with the firing pin (14), and safety devices coupled to the primer holder (17) in order to keep the fuze (1) in a safe state until at least two mutually independent physical phenomena linked to the firing of the round occur. The fuze (1) has a wind turbine (11) designed to be driven in rotation by the relative movement of the air during the flight of the round and to transmit this rotational movement to the primer holder (17) only after the safety devices have been removed.
