Abstract: A device, and method for using the device, for extracting a large-caliber projectile jammed in a barrel of a weapon including a solid body having a diameter smaller than the caliber of the barrel and intended to be introduced into the barrel at the muzzle of the latter and then released in the barrel in order to impact, by inertia, the jammed projectile. The device is at least two radially expandable locking mechanisms, each able to move between a locked position in which it is applied radially against the inner wall of the barrel and a released position in which it is not applied against the barrel, the passage of the locking mechanisms from one position to the other by an expansion apparatus, the device includes a translation device enabling a first locking mechanism to be translated axially to a second locking mechanism.

Abstract: An aiming method for a weapon system including a weapon secured to a chassis, as well as an aiming device implementing such a method. The weapon system includes a computer having in an internal memory a nominal firing profile defined by the extreme elevation and relative bearing aiming instructions that are possible for the weapon, in the reference frame associated with the chassis, when the latter is in a firing position on a horizontal ground. The boundaries of the nominal firing profile are converted so as to determine a transformed firing profile which is delimited by the extreme directions of fire that are possible in the reference frame of the chassis when the latter is in the firing position on the field, and finally the operating firing profile is determined for the aiming, which is defined as the geometric intersection of the nominal firing profile and the transformed firing profile.

Abstract: A gripping device for shells that includes a pair of jaws intended to clamp a shell, each jaw being able to pivot towards a closed position obtained by applying the top end of each jaw to the shell. A locking means links the top ends of the jaws and includes two connecting rods and a central segment linking these connecting rods.
