Title: Submarine signal fuze

Abstract: A signaling device to be launched underwater having a fuze body and a protile containing pyrotechnic compositions. The pyrotechnic compositions are ignited by an electrical squib which is detonated by voltage from a sea water battery which is sealed from sea water until a valve opens to permit entry of water into the fuze. An open circuit is provided between the battery and leads of the squib and, in addition, the squib leads are shorted. The opening of a valve to permit entry of sea water into the fuze causes the short to be removed and closes the circuit between the battery and the squib.
