A munition article is to be provided with an antenna which, by virtue of a characteristic which is uniform all around, permits interference-free reception of items of satellite navigation information, even if in the manner of an artillery projectile it is fired with spin along an elongate ballistic trajectory, so that a tail antenna with a spherical characteristic does not allow the expectation of good reception factors in relation to navigation satellites which are as high as possible above the horizon. Therefore the tip (10) of the fuse tip (11) of the projectile is equipped with a dipole satellite antenna which faces in the direction of flight. Connected to the dipole (13) which is arranged concentrically with respect to the longitudinal axis (14) of the projectile are symmetrically disposed conductor portions (15) which rest with a close fit in recesses (19) in the ballistic cap (12).
