    Abstract: The invention relates to a penetrating and explosive projectile (1) provided with a trajectory-stabilizing fin assembly (8) which is secured to a body of the projectile by a mechanical connection. The fin assembly (8) includes a tapped tube (14) which engages on a threaded rear cylindrical shank (10) of a tail (9) connected to the projectile body (2), thereby forming a threaded mechanical connection (13) between the tail unit (8) and the body (2). This projectile (1) is characterized in that it includes means ensuring the fragilization of the threaded connection (13) on impact on a target, the fin assembly then separating from the projectile body.

    Abstract: A sub-caliber projectile of the kinetic energy type comprising a perforating rod surrounded by a sabot made of light material and allowing the projectile to be fired from a weapon, the rod being extended by a stabilizing tail. The tail is connected to the rod by a connection means that can be broken, the breaking being initiated by a control means integral with the projectile. The control means comprises a timing module which is connected to a programming interface and which is programmed before firing or during firing so as to ensure the breaking of the connection means at a reference distance relative to a target which is to be neutralized. The invention also relates to a method of neutralizing a target using such a sub-caliber projectile.

    Abstract: An artillery projectile is configured to have a trajectory comprising a ballistic phase and a piloted phase. This projectile has at least one means ensuring its aerodynamic stabilization on part or all of its trajectory and a means configured to ensure a piloting during the piloted phase. This projectile is characterized in that the aerodynamic stabilization means comprises a wing system having at least two wings which are able to be positioned with respect to the axis of the projectile, at least during the piloted phase, with their sweepback angles being negative, that is, with the free ends of the wings being oriented towards the front of the projectile.

    Abstract: A shaped charge including an explosive load positioned in a casing, a liner applied on the load, and means ensuring the securing of the casing and the load bearing the liner. These securing means include a ring having a stop surface for the liner and at least two shims each covering an angular sector and moving radially by the action of a tightening means, to be pressed against an inner bearing surface of the casing. According to the invention, the tapped hole of the tightening screw(s) has its axis parallel to the axis of the casing and the shim is positioned axially relative to the ring by at least one radial pin authorizing sliding thereof.
