Abstract
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.
