A secondary self-destruct fuze that functions in the event the primary fuze mode fails to function, and that meets the design requirements for a low cost, highly producible no-spin/low velocity operating environment. The fuze includes a bottom plate, two spacers, a firing pin, a striker, a rotor, a pyrotechnic mix, a rotor spring, a striker spring, a weight with a firing pin, a weight spring, a bore rider, a bore rider spring, a housing, a handling safety pin, and a ribbon retainer. In use, the handling safety pin is removed upon loading of the grenade in the main carrier. When the grenade is ejected, the expulsion event forces the ribbon retainer to be uncovered and the ribbon to unfurl, which releases the safety lock feature. The unfurling of the ribbon in the air stream stabilizes the grenade by causing an upward pull force. Simultaneously, the air stream forces the bore rider and the bore rider spring out of the fuze. In addition, the upward pull force translates to the weight firing pin and causes the latter to move up and away from the rotor. Both the rotor and the striker are free to move under the action of their respective springs. The burning of the pyrotechnic mix is initiated by the striker firing pin hitting the match tip at the open end of the channel in the rotor. After a predetermined delay, the detonator is functioned. In the meantime, the rotor, together with the striker have moved into their respective in-line positions. Upon impact, the firing pin of the weight is forced into the detonator, thereby igniting the lead charge of the grenade.

[ What is claimed is:] [1.]1. A self-destruct fuze comprising:a rotor;a striker;a weight having a firing pin, for preventing the rotor from moving into an armed in-line position;a housing;a bottom plate for securing the rotor, the striker, and the weight inside the housing, with the striker and the rotor rotating along a top surface of the bottom plate; wherein the bottom plate includes a lock out tab that protrudes towards the rotor to prevent a return movement of the rotor after the rotor has moved into an in-line position, anda bore rider for retaining the weight and the rotor prior to firing.
