A pyrotechnic signal providing smoke and flame and which is launchable from underwater. 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.

A smoke and illumination signal adapted to be launched in a body of sea water beneath the surface thereof comprising, a base having a cavity therein, a sea water battery positioned within said cavity, a disc closing an opened end of said cavity, a shell attached to one end of said base containing a smoke composition and a flare composition separated by a quantity of a starter composition, said smoke composition being comprised, by weight, of between 50 and 54 percent of yellow dye mix, between 19 and 25 percent of potassium chlorate, between 10 and 16 percent of refined sugar, between 2 and 8 percent of baking soda and between 5 and 11 percent of diatomaceous earth and said flare composition being comprised by weight of between 17 and 21 percent of magnesium powder, between 12 and 22 percent of potassium perchlorate, between 24 and 34 percent of barium nitrate, between 23 and 31 percent of sodium oxalate, between 3 and 5 percent of asphaltum and between 3¾and 4¼percent of binder material, an electric squib adjacent said smoke composition and electrically connected to said sea water battery, an arming cup slidably and removably attached to said base, a first compression spring in said arming cup biasing said disc in a closing relationship with respect to said cavity, and a second compression spring within said cavity biasing said disc in an opening relationship with respect to said cavity whereby, upon launching of said signal, said first compression spring ejects said arming cup and said second compression spring ejects said disc. A smoke and illumination signal adapted to be launched in a body of sea water beneath the surface thereof comprising, a base having a cavity therein, a sea water battery positioned within said cavity, a disc closing an opened end of said cavity, a shell attached to one end of said base containing a smoke composition and a flare composition separated by a quantity of a starter composition, said smoke composition being comprised, by weight, of between 45 and 51 percent of green dye mix, between 22 and 28 percent of potassium chlorate, between 17 and 23 percent of refined sugar, between 2 and 4 percent of baking soda and between 3 and 5 percent of diatomaceous earth, and said flare composition being comprised, by weight, of between 13.28 and 17.28 percent of magnesium powder, between 18.92 and 24.92 percent of potassium perchlorate, between 43.55 and 49.55 percent of barium nitrate, between 10.00 and 16.00 percent of polyvinyl chloride and between 2.25 and 4.25 percent of binder material, an electric squib adjacent said smoke composition and electrically connected to said sea water battery, an arming cup slidably and removably attached to said base, a first compression spring in said arming cup biasing said disc in a closing relationship with respect to said cavity, and a second compression spring within said cavity biasing said disc in an opening relationship with respect to said cavity whereby, upon launching of said signal, said first compression spring ejects said arming cup and said second compression spring ejects said disc.
