A percussion fuse for artillery training ammunition such as mortar and howitzer projectiles. The training fuse assembly includes a body adapted for connection to a projectile body, a composition signal charge mountable within the fuse body and emitting report, smoke, and flash signals, and a striker unit for detonating the signal charge upon impact with a desired target. A combination safety system prevents premature detonation of the charge during handling, transportation, loading, and initial in-flight upward travel of the projectile. The fuse only becomes fully armed when the projectile reaches its terminal velocity and begins its downward flight toward the designated target. The armed fuse is highly sensitive and even upon impact with water will detonate in super quick fashion to discharge the entire signal before the projectile disappears below the surface of the water.

A fuse assembly for use in a projectile such as a mortar shell or the like, said assembly comprising: (a) a body, (b) striker means generally axially movably mounted within said body between a forward safe position and a rearward charge detonating position in which it causes detonation of a charge,

A fuse assembly for use in a projectile such as a mortar shell or the like, said assembly comprising: (a) a body, (b) striker means generally axially movably mounted within said body between a forward safe position and a rearward charge detonating position in which it causes detonation of a charge, (c) slider means mounted within said body for movement between a safe position in which it prevents movement of said striker means to said detonating position and a retracted armed position in which it permits movement of said striker means to said detonating position, (d) set-back means mounted within said body in a normal safe position in which it retains said slider means in safe position, (e) said set-back means being movable from said safe position to an armed position in response to a predetermined inertial force acting thereupon following propulsion of said projectile to release said slider means for movement to its armed position, and (f) blocking means mounted within said body for movement in response to gravity to a safe position during upward trajectory flight of said projectile in which it prevents movement of said striker means to said detonating position and to an armed position during downward trajectory flight of said projectile in which it permits movement of said striker means to said detonating position upon impact with a target.
