A grenade projectile has a projectile housing having a fragmentation length portion; an explosive charge accommodated in the projectile housing and being surrounded by the fragmentation length portion; a forwardly acting shaped charge liner bounding the explosive charge at a front end thereof, as viewed in the flight direction of the projectile; and a percussion fuse assembly accommodated in the projectile housing behind the explosive charge as viewed in the flight direction. The percussion fuse assembly includes a percussion member, a flight acceleration-responsive first safety arrangement and a centrifugal force-responsive second safety arrangement for arming the percussion member when the projectile reaches a predetermined acceleration and a predetermined spin.
