A flare release system in which a plurality of flares are sequentially launched from a submerged float. Launching apparatus for each flare comprises a compressed gas cylinder which is ruptured by a firing pin propelled by an electrically initiated squib. Compressed gas escaping from the cylinder powers an ejection piston to force a flare from the submerged float. An electric circuit distributes firing pulses to each flare launching mechanism according to a predetermined sequence.
