Patent ID: 8813628

Claim:
A combined weapon clearance device for clearing weapons under water by detonating the weapon, comprising an unmanned underwater vehicle and a weapon clearance device that is attachable thereto, wherein the weapon clearance device comprises: a retaining device for one of: fixing the weapon clearance device to the weapon, and retaining the weapon clearance device in close proximity to the weapon in an area surrounding the weapon, wherein the weapon clearance device is a driveless attachment for an unmanned underwater vehicle; and a releasable connection means for releasably securing the weapon clearance device to the unmanned underwater vehicle, wherein the weapon clearance device has one of a positive buoyancy and a negative buoyancy, and wherein, when the weapon clearance device has a positive buoyancy, the unmanned underwater vehicle has one of a lower positive buoyance than the weapon clearance device, a neutral buoyancy and a negative buoyancy, and when the weapon clearance device has a negative buoyancy, the unmanned water vehicle has one of a smaller negative buoyancy than the weapon clearance device, a neutral buoyancy and a positive buoyancy, such that an overturning moment is produced about a transverse axis of the combined weapon clearance device.
