A fuze for a spin-stabilized artillery projectile comprises a body includ: an ogive member containing point-detonating firing means, selectable for super-quick or delay firing; and a base member containing an inertial delay fuze operable by either direct or graze impact, a combustible fuse loop surrounding the inertial delay fuze and exposed to the point-detonating firing means, and a firing train coupling the inertial delay fuze and the fuse loop to a booster charge for initiating the main explosive charge of the projectile. The inertial delay fuze may comprise a cylindrical housing including a rear wall, an outer cylindrical wall and a front wall including a rearward tubular extension forming an annular chamber, a rearwardly-biased firing pin slidable in the tubular extension, a rearwardly-biased, annular, locking member slidable in the annular recess from a rear position, wherein it engages a series of detent balls which hold the firing pin in safe position, to a forward, firing pin-releasing position, a detonator positioned to be fired by the firing pin, and a series of spherical inertial weights which engage inclined cam surfaces on the locking member to force the latter forwardly on graze impact with a target.
