An experimental exploding bridge wire initiator was developed as part of a continuing program to devise methods to protect modern ordnance systems from inadvertent actuation by electromagnetic radiation. Tests were conducted to determine the susceptibility of this item to initiation by electromagnetic energy. The tests demonstrated that while the initiators could not be fired in a normal fashion by exploding the bridge wire by radio frequency energy fields encountered in present service conditions, the units could be initiated by cook-off following burn out of the bridging wire. Actuation in this manner is due primarily to dielectric heating in the nylon dielectric material. It is recommended that the nylon be replaced with a more suitable material before any further electromagnetic energy susceptibility tests are conducted.
