Claims

• 1. A device for countering an underwater target, said device comprising: a module; at least one inflatable section joined to said module; at least one propulsor extendable from said module, said propulsor capable of maneuvering said module to a firing position; and a gun partially encompassed by said module for firing at least one projectile from the firing position to counter the underwater target. 2. The device in accordance with claim 1 wherein said inflatable portion includes a plurality of inflatable chambers distributed around a perimeter of said module. 3. The device in accordance with claim 2 said device further comprising means for detecting the underwater target operably joined to said module, said propulsor and said gun. 4. The device in accordance with claim 3, wherein said device further comprises means for clearing said gun with compressed air. 5. The device in accordance with claim 2, wherein said device further comprises means for clearing said gun with compressed air. 6. A device for countering an underwater target, said device comprising: an autonomous module; at least one propulsor extendable from said module, said propulsor capable of maneuvering said module to a firing position; a gun partially encompassed by said module for firing at least one projectile from the firing position to counter the underwater target; and means for acoustically detecting the underwater target, said means operably joined to said module, said propulsor and said gun. 7. The device in accordance with claim 6, wherein said device further comprises means for clearing said gun with compressed air. 8. A method for countering an underwater target comprising the steps of: providing an autonomous hydrodynamic module having at least one propulsor and a gun; deploying said hydrodynamic module; acoustically detecting the underwater target; deploying said at least one propulsor; maneuvering said module with said at least one propulsor to a firing position; and firing said gun from the firing position thereby countering the underwater target. 9. The method in accordance with claim 8 wherein said firing step further comprises clearing said gun with compressed air. 10. The method in accordance with claim 9, wherein said firing step further comprises subsequently firing at the underwater target after clearing said gun. 11. The method in accordance with claim 10, further comprising the step of recovering said hydrodynamic module subsequent to said firing step. 12. The method in accordance with claim 10, further comprising the step of sinking said hydrodynamic module to a bottom of a body of water subsequent to said firing step. 13. The method in accordance with claim 10, said method comprising the further step of inflating chambers around the perimeter of said hydrodynamic module in order to maneuver said hydrodynamic module.
