Abstract : A signaling device to be launched underwater having a fuze body, a time delay element, an ejection charge and at least one carrier having a pyrotechnic composition attached to a parachute . 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. Pyrotechnic signals are used to indicate the presence of a submerged submarine to a surface ship. A smoke device provides a better signal at night. In order to eliminate the need for having two types of signals, frequently a signaling device is made that contains both a smoke charge and a flare charge.
