Float Smoke and Flame
This buoyant device is designed to be released from helicopters and fixed wing aircraft to indicate a position in the sea for both day and night marking. The device operates either by contact with sea water via a sea cell (No.2 Mk.3) or impact using a percussion mechanism (No.1 Mk.5). The float may be carried and released from bomb carriers, small bomb dispensers and launching chutes or it may be dropped by hand from helicopters.
