Gyrostabilized projectile

A gyrostabilized projectile including a hollow body carrying a payload formed of a set of sub-projectiles, wherein the sub-projectiles are inert and configured to be dispersed on a trajectory, the projectile including a single cup that contains the sub-projectiles and includes a piston closing one of the ends of the cup, a rear part of the body being provided with a base housing a pyrotechnic charge separated from the sub-projectiles by the piston, wherein the piston configured to translate with respect to the body so as to push the cup and the sub-projectiles axially out of the body, the cup being substantially cylindrical and of a diameter corresponding to that of a cylindrical bore inside the body, the cup being formed by assembly of at least two sectors, independent of each other and joined along edges thereof that are parallel to a longitudinal axis of the projectile, wherein the piston is secured to the sectors when the piston and the sectors are contained in the body and the cup is secured to the body by a weakened connecting means configured to break under a force applied by the piston when the piston is pushed by gases generated by the pyrotechnic charge, an ogive being secured to the cup with a securing means that is coaxial with the longitudinal axis of the projectile and locked by the sectors of the cup.
