Abstract : A decoy capable of assuring the shape of a water craft comprises a maneuverable vessel, having a tubular body portion which defines an enclosed interior region. The vessel further has an opening formed in the body portion and a hatch door which covers the opening. An energy source powers the operation of the vessel, and a drive module propels the vessel under the water. A selectively deployable bladder is stored within the vessel in its interior region and is selectively deployable from a stowed position in which the bladder is contained within the interior region of the vessel to a deployed position in which the bladder exits the vessel through the opening and is inflated with gas for assuming the shape of a water craft. An inflation system inflates the bladder with gas when deploying the bladder. The decoy can also be provided with electromagnetic, infrared and acoustic decoy projectors for projecting the characteristics of the water craft.
