ABSTRACT:
An omnidirectional impact and self-destruct fuze for initiation of a gren has a primer which after being initiated ignites a delay column. The delay column melts an eutectic metal arming plug which unlocks a ball detent to permit a striker assembly to be responsive to an impact sensor. If upon impact the inertial force of an impact weight fails to displace an impact spring so that it will release the spring biased striker against a detonator, the burning delay column will subsequently ignite a flash mix and melt a self-destruct nut, thereby releasing a retainer screw and the striker assembly therefrom so that the latter will forcibly hit the detonator causing the grenade to self-destruct.
