Abstract: The invention is an improved process for programming electronic fuzes, whby the fuze facility may be reprogrammed electronically without the need for disassembly and replacement of components of the circuitry. The invention comprises a circuit arrangement which provides a secondary receiving coil, of the reprogrammable electronic fuze system, that is positioned adjacent to the interior surface of a munition wall so that it can easily pick up high frequency programming signals from an external drive circuit. The receiving coil feeds programming signals to a rectifier. The output of the rectifier encodes a bubble memory. The bubble memory can be reprogrammed anytime prior to the use of the munition, by the same procedure. When the munition is deployed a launching mechanism closes an activation switch to the munitions power supply and at the same moment a short high frequency arming pulse from the external signal activates the internal power supply.
