Abstract

A system and method is provided to replenish a submarine'"'"'s tactical capabilities, e.g., weapons, sensors and communications, while the submarine remains within a hostile environment. One or more Underwater Combat Vehicles (UCV'"'"'s) are pre-positioned at strategic locations or are launched from a surface and/or airborne platform. The UCV'"'"'s include full tactical capabilities, which can attach to and be integrated with a submarine'"'"'s capabilities. To initiate replenishment, a submarine broadcasts a signal, or dispatches one of the UCV'"'"'s under its direct control, to make contact with one of the pre-positioned UCV'"'"'s or with a central command platform. The pre-positioned UCV'"'"'s are programmed to search for and locate the submarine. This can either be accomplished using signals broadcast from the submarine, or using UCV internal navigation systems and a last known position for the submarine. Once located, communication between the submarine and UCV allows docking of the UCV onto the submarine.

Claims

1. A system for replenishing tactical capabilities of a submarine while remaining within a battle environment, the system comprising:

a first unmanned combat vehicle launched from the submarine and having one or more depleted suites of tactical equipment, the unmanned combat vehicle serving as an adjunct to the tactical capabilities of the submarine when attached to the submarine with no depleted suites of tactical equipment; and

at least one second unmanned combat vehicle having full suites of tactical equipment and programmed to search for, locate and dock with the submarine when informed that the first unmanned combat vehicle has one or more depleted suites of tactical equipment, the at least one second unmanned combat vehicle serving as the adjunct to the tactical capabilities of the submarine in lieu of the first unmanned combat vehicle.

2. The system of claim 1, wherein each of the at least one second unmanned combat vehicles is pre-positioned at a strategic location remote from the battle environment.

3. The system of claim 2, wherein the first unmanned combat vehicle is programmed to make direct contact with the at least one second unmanned combat vehicle to inform the at least one second unmanned combat vehicle.

4. The system of claim 2, wherein at least two second unmanned combat vehicles are pre-positioned, the at least two second unmanned combat vehicles forming a sensor net about the battle environment.

5. The system of claim 2, wherein:

the first unmanned combat vehicle is programmed to return to the submarine; and

the submarine programs the first unmanned combat vehicle to inform the at least one second unmanned combat vehicle.

6. The system of claim 5, wherein the first unmanned combat vehicle is programmed to make direct contact with the at least one second unmanned combat vehicle to inform the at least one second unmanned combat vehicle.

7. The system of claim 5, wherein:

the first unmanned combat vehicle is programmed to proceed to a previously determined rendezvous site;

the first unmanned combat vehicle makes contact with a control platform nearby the rendezvous site; and

the control platform makes contact with the at least one second unmanned combat vehicle to inform the at least one second unmanned combat vehicle.

8. The system of claim 1, wherein the first unmanned combat vehicle is programmed to make direct contact with the at least one second unmanned combat vehicle to inform the at least one second unmanned combat vehicle.

9. The system of claim 1, further comprising:

a control platform capable of communicating with the at least one second unmanned combat vehicle, wherein;

the first unmanned combat vehicle is programmed to proceed to a previously determined rendezvous site;

the first unmanned combat vehicle makes contact with said control platform nearby the rendezvous site; and

the control platform makes contact with the at least one second unmanned combat vehicle to inform the at least one second unmanned combat vehicle.

10. The system of claim 9 wherein the at least one second unmanned combat vehicle informed is pre-positioned in a strategic location remote from the battle environment.

11. The system of claim 9, wherein the at least one second unmanned combat vehicle informed is launched from the control platform.

12. The system of claim 1, wherein:

the first unmanned combat vehicle is programmed to return to the submarine; and

the submarine programs the first unmanned combat vehicle to inform the at least one second unmanned combat vehicle.

13. The system of claim 1, wherein the submarine signals the at least one second unmanned combat vehicle to assist the at least one second unmanned combat vehicle in locating the submarine.

14. The system of claim 1, wherein the at least one second unmanned combat vehicle has an inertial guidance system and a last known location of the submarine, the at least one second unmanned combat vehicle being programmed to travel to the last known location of the submarine and search for the submarine.

15. A method of replenishing tactical capabilities of a submarine within a battle environment, comprising:

informing a replenishment unmanned combat vehicle having full suites of tactical capabilities that an adjunct unmanned combat vehicle associated with a submarine has depleted one or more tactical suites; and

launching the replenishment unmanned combat vehicle to search for, locate and dock with the submarine in accordance with previously programmed instructions.

16. The method of claim 15, further comprising pre-positioning the replenishment unmanned combat vehicle at a strategic location near the battle environment.

17. The method of claim 15, wherein informing the replenishment unmanned combat vehicle further comprises programming the adjunct unmanned combat vehicle to make direct contact with the replenishment unmanned combat vehicle.

18. The method of claim 15, wherein informing the replenishment unmanned combat vehicle further comprises:

programming the adjunct unmanned combat vehicle to proceed to a predetermined rendezvous location;

programming the adjunct unmanned combat vehicle to contact a control platform near the rendezvous location; and

contacting the replenishment unmanned combat vehicle from the platform.

19. The method of claim 15, wherein informing the replenishment unmanned combat vehicle further comprises:

programming the adjunct unmanned combat vehicle to return to the submarine; and

programming the adjunct unmanned combat vehicle from the submarine to contact the replenishment unmanned combat vehicle.
