A fuze of the type used in a rifle grenade assembly with a striker, a rotor and a rotor lock includes one or more improvements. One pertains to the striker to prevent it from reaching a detonator-striking forward position more than once. Once it advances to the forward position it is locked in it by a spring biased locking pin. Other improvements relate to the release of the rotor by the rotor lock. The rotor remains locked, i.e. in the disarmed state even after intentional launching. It is released to assume the armed state only when the launched assembly accelerates at a certain rate toward the target.

In a fuze of the type used in an explosives\launching assembly, the fuze including a striker, a rotatable rotor, a detonator in said rotor, a rotor lock adapted to be in a disarmed state in which said rotor lock inhibits said rotor from turning and thus prevents the detonator from being aligned with

In a fuze of the type used in an explosives\launching assembly, the fuze including a striker, a rotatable rotor, a detonator in said rotor, a rotor lock adapted to be in a disarmed state in which said rotor lock inhibits said rotor from turning and thus prevents the detonator from being aligned with the fuze\s striker and in an armed state in which said rotor lock is separated from said rotor, the fuze further including control means for controlling said rotor lock to change from the disarmed state to the armed state only as a result of intentional launching, the improvement comprising: rotor lock safety means for inhibiting said rotor lock from changing from said disarmed state to the armed state even after intentional launching until acceleration forces of preselected magnitude are applied to said rotor lock.
