A slider type fuse for a cargo warhead grenade. The slider is slidable in a plane normal to the axis of the striker pin and carries additional to the detonator a pyrotechnic device comprising an igniter charge, a booster charge removed therefrom and located in close proximity to the detonator, a delay charge between the two and swingable striker means which become unlocked in the armed state and are adapted to strike the igniter charge in consequence of centrifugal forces that develop in the course of flight. The delay of the pyrotechnic device is designed to outlast the flight time of the grenade. Whenever the striker does not strike the detonator when the grenade hits the target, the detonator is initiated by the booster charge of the pyrotechnic device.

A slider type fuse for a cargo warhead grenade comprising a housing adapted for mounting on said grenade and accommodating a striker pin assembly having a collar and a shaft screwingly mounted therein, which shaft has an inner end portion fitted with a striker pin and an outer tail portion adapted to carry drag producing means and is capable of being unscrewed and thereby to move within said collar in axial direction from a forward, locking to a retracted, armed position, the housing further accommodating a slider holding detonator means adapted for impact ignition by said striker pin, which slider is moveable radially from a retracted position in which said detonator means are out of alignment with said striker pin to a forward position in which said detonator means are in alignment with said striker pin, said slider being locked in the retracted position by said striker pin and being unlocked when said striker pin is retracted, the improvement by which said slider is moveable from the retracted to the forward, armed position by centrifugal forces resulting from the spin of the cargo warhead grenade; and further characterised by delayed action ignition means accommodated within said slider and comprising an igniter charge, a booster charge removed therefrom and located in close proximity to said detonator means and a delay charge located between the two, and swingable striker means associated with said igniter charge swingably mounted on the slider near an end thereof which projects out of said housing when the slider is in the forward, armed position, which swingable striker means are blocked in the retracted position and are unlocked in the forward, armed position of the slider and are capable of swinging by the action of centrifugal forces resulting from the spin of the cargo warhead grenade thereby to strike said igniter charge.
