Abstract: A projectile (3) to be launched by a marksman toward a target using a launch device, the projectile comprising a shaped-charge warhead (14) whose axis (38) coincides with that of the projectile, initiation of which is caused by an igniter (17). The projectile is characterized by a shaped charge which generates a core, and igniter (17) initiates the shaped charge along the trajectory and at a given distance from the launch device so that the marksman is protected from projectile explosions.

Abstract: A dispersible countermass system for a recoilless weapon, designed to be installed in a weapon barrel and to be ejected on firing through a rear portion thereof by a piston driven by the pressure of the combustion gases of a propellant charge while a projectile is simultaneously being launched towards the front portion of the barrel, the system comprising a charge of dispersible and inert matter disposed inside a case that is closed by a cover and by an end, wherein the case is formed by a cylindrical wall that fits inside the barrel and that is prevented from moving in translation relative thereto, and wherein the cover is connected to the case via connection means that are ruptured by the piston on firing, the case serving to guide the piston which has a peripheral rim that remains in contact with the case so as to provide sealing for the gases, the piston thus serving to eject the inert matter from the barrel.

Abstract: A housing has a scored cylindrical casing that is designed to slidably fit into the barrel of a weapon and that is delimited by two side walls. After the casing breaks, due to the pressure of gases generated by a propellant charge, the housing is divided into at least two parts that are free to move relative to each other. Each housing part carries one casing element, ensuring gas tightness.

Abstract: A device for reducing drag of a round of ammunition or projectile (1) comprises a gas-producing compound (3) such as a propergol, the combustion of which generates gases at a pressure of at least sufficient value to fill the low-pressure region which is formed at the rear end of a projectile and causes drag. The device comprises a gas-tight casing (2) containing the explosive compound (3) and an igniter (6) for initiating combustion of the compound. The casing comprises fasteners which cooperate with complementary fasteners (11) arranged at the rear end of the round of ammunition so as to permit gas-tight fitting of the casing at the rear end of the projectile, at any moment and in particular at the firing location, in order to reduce drag and to increase the range of the projectile.
