Abstract

A mine neutralizing device that includes a buoy. The buoy includes a mine neutralizing device capable of swimming to an undersea mine to neutralize it. A method for neutralizing undersea mines includes locating an undersea mine, placing a buoy containing a mine neutralizer near the mine, and swimming the mine neutralizer to the undersea mine.

Claims

1. A system for neutralizing mines comprising:

a buoy that further includes;

a transceiver for sending and receiving signals;

a processor; and

memory communicatively coupled to the processor; and

a mine neutralizer housed within the buoy;

a mechanism for moving the mine neutralizer to a position clear of the buoy; and

a heading sensor for determining a heading of the mine neutralizer, the mine neutralizer controllable remotely via a communicative couple to the buoy, the heading sensor providing feedback to the buoy wherein the buoy further comprises a mechanism for pulling an arming pin of the mine neutralizer that is associated with the mechanism for moving the mine neutralizer to a position clear of the buoy.

2. The system for neutralizing mines of claim 1 wherein the heading sensor includes a plurality of hydrophones for:

detecting sounds produced by a moving mine neutralizing device; and

determining a location of the mine neutralizing device from the detected sounds.

3. The system for neutralizing mines of claim 1 wherein the buoy includes a GPS receiver for determining a position of the buoy.

4. The system for neutralizing mines of claim 1 wherein the buoy further comprises:

a fiber optic card communicatively coupled to the processor and memory;

an optical link to the mine neutralizing device.

5. The system for neutralizing mines of claim 4 wherein the optical link to the mine neutralizing device includes an optical fiber connecting the mine neutralizing device to the buoy.

6. The system for neutralizing mines of claim 1 further comprising a remote control station communicatively coupled to the buoy, the remote control station receiving data from the buoy and sending commands to the mine neutralizer by way of the buoy.

7. The system for neutralizing mines of claim 1 further comprising:

an unmanned remote control vehicle for deploying at least one buoy; and

a remote control station communicatively coupled to the unmanned remote vehicle, the remote control station receiving data from the unmanned vehicle and sending commands to the unmanned vehicle.

8. The system of claim 7 wherein the unmanned vehicle further comprises:

a main body having a bow end and a stern end;

a propulsion unit attached to the stern end of the main body;

a rail system attached to the main body between the first end and the second end of the main body, the rail system adapted to hold at least one buoy assembly to the rail system as the propulsion unit drives the unmanned vehicle; and

a deployment mechanism for controllably releasing the at least one buoy from the rail system.

9. The unmanned vehicle of claim 8 wherein the propulsion unit is shrouded.

10. The unmanned vehicle of claim 8 wherein the buoy assembly includes a fairing and a neutralizer buoy, the buoy assembly attached to the rail system of the unmanned vehicle.

11. The unmanned vehicle of claim 10 wherein the main body includes at least one hook movable between a retain position and a deploy position, the hook moved to the deploy position to launch the buoy assembly from the unmanned vehicle.

12. The unmanned vehicle of claim 11 wherein the fairing includes a door through which the hook extends to the neutralizer buoy, the fairing falling away from the neutralizer buoy upon deployment.
