Claims
- 1. An unmanned underwater vehicle comprising:
a hull; a propulsion unit joined to said hull for maneuvering said vehicle; and an attachment means joined to said hull to attach said vehicle to a submarine.
- 2. A vehicle according to claim 1 wherein said attachment means comprises:
a corkscrew member rotatably joined to said hull and extendable therefrom; and a motor joined to drive said corkscrew member.
- 3. A vehicle according to claim 1 wherein said attachment means comprises at least one permanent magnet located at a surface of said hull.
- 4. A vehicle according to claim 3 wherein said attachment device further comprises a motor joined to extend said at least one permanent magnet.
- 5. A vehicle according to claim 1 further comprising a resilient material coating said hull.
- 6. A vehicle according to claim 1 further comprising forward and rear control surfaces joined to said hull.
- 7. A vehicle according to claim 1 wherein said hull is shaped to create a venturi effect.
- 8. A vehicle according to claim 1 further comprising thrusters joined to said hull to act as suction devices.
- 9. A vehicle according to claim 1 wherein said propulsion unit includes at least one propeller, a motor-generator driving said at least one propeller, and a battery joined to power and be recharged from said motor-generator.
- 10. A vehicle according to claim 9 wherein said at least one propeller is turned by water when said vehicle is attached to said submarine and said motor-generator recharges said battery.
- 11. A vehicle according to claim 1 further comprising means for revealing a location of the vehicle.
- 12. A vehicle according to claim 11 wherein said location revealing means comprises a dye marker.
- 13. A vehicle according to claim 11 wherein said location revealing means comprises a floating radio frequency beacon.
- 14. A vehicle according to claim 1 further comprising at least one transducer positioned in said hull for monitoring the acoustic environment.
- 15. A vehicle according to claim 14 further comprising:
a controller joined to said transducer; and a signal processor positioned in said hull and joined to said transducer wherein said at least one transducer is configured to act as an echo-repeater to create an acoustic homing signal for a torpedo.
- 16. A vehicle according to claim 1 further comprising a projector positioned in said hull for transmitting an acoustic signal.
- 17. A vehicle according to claim 1 further comprising:
a depth gauge positioned in said hull; a speed sensor positioned in said hull; and a data storage means joined to said depth gauge and said speed sensor.
- 18. A vehicle according to claim 17 further comprising means for uploading stored data joined to said data storage means.
- 19. A method for intercepting a submarine and covertly reporting the activities of the submarine comprising:
launching an unmanned underwater vehicle from a platform in the vicinity of said submarine; targeting a particular area of the submarine suited for stealthy and long-term attachment; navigating said unmanned underwater vehicle to said targeted area; and attaching said unmanned underwater vehicle to said submarine.
- 20. The method according to claim 19 further comprising orienting the unmanned underwater vehicle with respect to a hull of the submarine in a manner to promote attachment.
