Abstract: A fuze for a submunition comprises a fuze housing with a stabilizer ribbon for aerodynamic orientation, a fuze slider released by tension on the stabilizer ribbon, an air-powered electric generator extended into the airstream by the fuze slider and powered in flight by high-speed airflow, a MEMS safety and arming device, a fuze circuit board including an explosive fireset, and an electrically initiated firetrain. The fuze is fixed to and communicates explosively with the end of a grenade warhead.
