Abstract: A disconnect device, suitable for placement into a mooring line connecting a floating vessel to an anchor, has a pair of rotably connected lever arm members. In a first, closed position, the lever arm members are held closed by a shear pin. Mating slots in each lever arm member capture a mooring line component, such as the pin of a shackle, when the lever arm members are closed. A cylindrical centering device is placed in the mooring line between the disconnect device and the vessel, and bears against the lever arm members. Force applied to the centering device, whether by pulling it into a surface fairlead sheave or similar device, or by a subsea chaser device, forces the lever arm members apart, breaking the shear pin and releasing the device, thus disconnecting the mooring line.

Abstract: An underwater intelligence gathering weapon system accurately places a weapon underwater and then communicates therewith from other platform(s). The weapon is equipped to maneuver through the air to a destination at the water's surface. A first transceiver, mounted onboard the weapon and coupled to the mine's logic portion, is activated after the weapon is in the water. The first transceiver can send and receive magneto-inductive signals. A second transceiver that sends and receives magneto-inductive signals is remotely located with respect to the first transceiver. Once deployed, the weapon can be controlled from a safe distance and can report any intelligence information collected by onboard sensors.

Abstract: An interdiction system to be placed upon the floor of the ocean includes a arget detection and classification system which is cooperatively connected to a hollow enclosure containing a predetermined volume at one atmosphere or less pressure. Upon target aquisition and classification, the detection and classification system actuates a mechanism to rupture the wall of the hollow enclosure. The resultant implosion caused by the ambient ocean pressure creates a high intensity shock wave in the vicinity of the system to damage the intruding vessel.

Abstract: A buoy mooring device and system adapted to maintain a buoy in an upright untilted position. A rigid bail having a center of curvature essentially coincident with the buoy center of buoyancy is connected to the bottom of the buoy. A mooring line having an anchor on one end is attached on the other end to the bail by a movable connecting means. As wind and/or water currents tend to tilt the buoy, the mooring system maintains the buoy in an upright position. Alternative embodiments include mooring systems comprising foldable bails and systems comprising multiple bails.

Abstract: A system for mooring a buoyant case such as a marine mine or other marine vice at a preselected depth below the surface of the water in which the case was launched. After the case has been launched, and made bottom contact, the mooring system utilizes a first piston assembly in conjunction with a corrodible pin to initiate mooring line payout from a buoyant case to an attached anchor. When the preselected mooring depth is reached, a second piston assembly terminates the mooring line payout and the ascent of the case, thereby resulting in mooring of the buoyant case at the preselected depth.

Abstract: A system for mooring a buoyant case such as a marine mine or other marine vice at a preselected depth below the surface of the water in which the case was launched. After the case has been launched, together with an attached anchor, the anchor and case separate to the extent of a resilient line as they descend through the water. When the case passes through a first preselected depth the resilient line is released from the case, thereby permitting a mooring line, which is connected in series between the resilient line and the case, to payout. As the mooring line unwinds the anchor descends to the ocean floor while the buoyant case ascends toward the surface. When the case ascends through a second preselected depth a brake assembly is activated to stop the payout of the mooring line. After the case has been positioned at the second depth, a locking assembly fixes the position of the case at the mooring depth.
