An electronic safe arming and fuzing (ESAF) system using an accelerometer capable of sensing the acceleration of a missile and supplying an electric signal upon measuring a predetermined level of acceleration. The accelerometer signal is supplied to an electronic timer which upon the receipt of said signal initiates a timing circuit. A predetermined time after receipt of the accelerometer signal the timer causes a high voltage to be stored on a large capacitor. An electronic switch is connected between the capacitor and an exploding bridge wire detonator and will cause the energy stored in the capacitor to pass through the exploding bridge wire (EBW) upon receipt of a proper triggering signal from a trigger means. The EBW detonator is imbedded in a secondary explosive and causes said explosive to detonate without the aid of a primary explosive when said trigger signal is received.

A system for arming a warhead of a missile after said missile has reached a predetermined distance from a launch vehicle and detonating said warhead upon the occurrence of a triggering event, said apparatus comprising: an exploding bridge wire imbedded in the explosive of said warhead; a first system branch comprising: first accelerometer means for detecting a predetermined acceleration force and closing a first switch upon experiencing said acceleration force; voltage regulator means electrically connected to said first accelerometer means such that electric energy is supplied to said regulator means when said switch is closed; energy conversion means connected to said regulator means for converting a relatively low direct current voltage to a relatively high direct current voltage; capacitor means connected to the output of said converter means for storing electrical energy; switch means connected between said energy storage means and said exploding bridge wire for allowing said stored energy to pass through said exploding bridge wire upon the occurrence of said triggering event; a second system branch comprising: second accelerometer means for generating an output signal upon detecting said predetermined acceleration force; electronic timer means connected to said second accelerometer, said timer means being adapted to generate an output signal a predetermined time period after receiving the output signal from said second accelerometer means; and means interconnecting said timer means and said first system branch for preventing energy from reaching said capacitor means prior to the receipt of the output signal from said timer means.
