Abstract
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.
