Abstract

Multiple LRSWs are launched to place at least one follower LRSW in a trailing position to at least one lead LRSW in a lead wave. Knowledge of the target space and particularly the primary target gained by the lead LRSWs is transmitted to the follower LRSWs (either directly or via another communication platform such as a satellite or UAV) and incorporated by the follower LRSWs to inform target selection. The follower LRSWs in the following wave trail the lead LRSWs in the lead wave with sufficient spacing in time and distance to inform target selection and with range remaining to maneuver to the selected target. This knowledge may be transmitted back to another follower LRSW (together with any data acquired the initial follower LRSW) and so forth in a “string” of LRSWs to inform target selection and maneuver the LRSWs to the primary target or an alternate target.

First claim

We claim:

1. A method of coordinating Long-Range Strike Weapons (LRSWs) to attack one or more targets, comprising:
launching a lead LRSW to attack a primary target in a lead target set;
launching a follower LRSW in a trailing relationship to the lead LRSW;
from the lead LRSW, collecting and processing observational sensor data of a target scene to attack either the primary target or an alternate target from the first target set and transmitting the observational sensor data and processed mission data via a communication link;
from the follower LRSW, receiving and processing the observational sensor data and processed mission data from the lead LRSW via a communications link to inform selection of a target from a follower target set including the primary target and at least one alternate target; and
timing the launch of the follower LRSW such that the follower LRSW receives and processes the observational sensor data to inform selection of the target with range remaining to attack either the primary target or the at least one alternate target.

2. The method of claim 1 , wherein each of said lead LRSW and said follower LRSW are capable of autonomously attacking the selected target.

3. The method of claim 1 , wherein the lead LRSW transmits the observational sensor data and processed mission data directly to the follower LRSW.

4. The method of claim 3 , wherein the follower LRSW retransmits the observational sensor data and processed mission data along a direct line of sight to a ground station.

5. The method of claim 1 , wherein the follower LRSW is launched in the trailing relationship to the lead LRSW to attack the primary target, receives and processes the observational sensor data and processed mission data from the lead LRSW to inform final selection of either the primary target or an alternate target in the follower target set and receives and processes its own observational sensor data to select an aimpoint on the selected target.

6. The method of claim 1 , wherein said lead LRSW comprises an impact sensor, said observational sensor data comprises impact data of the lead LRSW impacting the target.

7. The method of claim 1 , wherein the follower LRSW collects and process observational sensor data, wherein the follower LRSW receives an initial transmission of observational sensor data and processed mission data prior to the follower LRSW being within range to acquire the target selected by the lead LRSW.

8. The method of claim 7 , wherein the follower LRSW receive a final transmission of observational sensor data and processed mission data prior to the follower LRSW being within range to acquire the target selected by the lead LRSW.

9. The method of claim 7 , wherein the follower LRSW acquires the selected target prior to the lead LRSW's attack on that target and collects and processes real-time observational sensor data of the lead LRSW's attack on the target.

10. The method of claim 1 , wherein the follower LRSW collects and processes observational sensor data and transitions to become a lead LRSW once in range to acquire targets in the second target set.

11. The method of claim 1 , further comprising:
determining a flight path for the lead LRSW that deviates from a minimum time flight to the primary target to collect, process and transmit observational sensor data for one or more possible targets or non-targets along the flight path.

12. A method of coordinating Long-Range Strike Weapons (LRSWs) to attack one or more targets, comprising:
launching a first wave of multiple N lead LRSWs to attack one or more primary targets in a lead target set;
launching a second wave of multiple M follower LRSW in a trailing relationship to the first wave where M<=N;
from each of the lead LRSWs in the first wave, collecting and processing observational sensor data of a target scene to attack either one of the one or more primary targets or an alternate target from the lead target set and transmitting the observational sensor data and processed mission data via a communication link;
from each of the follower LRSWs, receiving and processing the observational sensor data and processed mission data from at least one of the lead LRSWs in the first wave via a communications link to inform selection of a target from a follower target set including at least one of the one or more primary targets and at least one alternate target; and
timing the launch of the second wave of follower LRSWs such that the follower LRSWs receives and processes the observational sensor data to inform selection of the target with range remaining to attack either the at least one primary target or the at least one alternate target in the follower target set.

13. The method of claim 12 , wherein M<N.

14. The method of claim 13 , wherein the lead target set includes a plurality of primary targets, wherein the M follower target sets together include all of the primary targets in the lead target set, wherein at least one of the follower LRSWs receives and processes observational sensor data and processed mission data from a plurality of the lead LRSWs with range remaining to attack the plurality of primary targets in it's follower target set.

15. The method of claim 14 , further comprising pre-programming each follower LRSW to identify the subset of one or more lead LRSW the follower LRSW receives data from and their targets.

16. The method of claim 14 , further comprising pre-programming each follower LRSW to listen to a plurality of the lead LRSWs and to relatively weight the data from said plurality of lead LRSWs to inform the follower LRSW's target selection.

17. The method of claim 14 , further comprising transmitting data among the follower LRSWs in the second wave to inform target selection of each follower LRSW.

18. The method of claim 14 , wherein the follower LRSWs receive observational sensor data and processed mission data directly from one or more lead LRSWs.

19. The method of claim 14 , wherein each said follower LRSW is launched in the trailing relationship to the first wave of lead LRSWs to attack one of the primary targets, receives and processes the observational sensor data and processed mission data from the one or more lead LRSWs to inform final selection of either the primary target or an alternate target in its own follower target set and receives and processes its own observational sensor data to select an aimpoint on the selected target.

20. The method of claim 14 , further comprising:
determining a flight path for each said lead LRSW that deviates from a minimum time flight to its primary target to collect, process and transmit observational sensor data for one or more possible targets or non-targets along the flight path.
