Abstract

The invention relates to so-called fuze damping in projectiles, in particular, those provided with a built-in firing delay. Thus, a projectile (1) is provided having a rear part (1a) and a fuze (2), wherein at least one damping element (7) is inserted between a fuze base (5) and the projectile (1) and/or between a fuze shoulder (6) and a possible threaded ring (4), or similar attachment element. The damping element (7) is in the form of a disc, ring or pot, and is composed of a material with a lower acoustic impedance than the material of the projectile (1).
