Abstract
An inflatable buoy assembly includes a flotation receptacle (12), a propellant breech (14), and an equipment container (16). These three components are designed for telescoping engagement and packaging in a single housing (78). When deployed, the breech is suspended below the flotation receptacle. The equipment container, in turn, is suspended below the propellant breech. As propellant gases escape from the breech, they rise through the water in which the assembly is submersed and are captured in a cavity (26) at the bottom of the flotation receptacle. The gases then pass through apertures in the bottom of the receptacle and are captured within the gas bag (24) forming part of the flotation receptacle.
