A signaling device to be launched underwater having a fuze body, a time dy element, an ejection charge and at least one carrier having a pyrotechnic composition attached to a parachute. The ejection charge is ignited by an electric squib which is detonated by voltage from a sea water battery. The battery is sealed from sea water until a valve opens to permit entry of water into the fuze body. An electronic deplay module is electrically connected between the sea water battery and squib to delay detonation of the ejection charge until the signaling device has assumed a stable vertical position at the water surface.

Underwater launched parachute flare

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.

Submarine signal fuze

A pyrotechnic signal providing smoke and flame and which is launchable from nderwater. Launching of the signal from underwater arms the signal, however, the signal is not initiated until the ambient sea pressure reaches a predetermined pressure valve. When this predetermined pressure valve is reached, sea water enters a cavity and energizes a battery which detonates an electric squib. The squib, in turn, ignites a smoke composition in the signal housing.
