A method, system and computer readable media for route re-planning including generating enemy force movement predictions to be used during mission planning. During a mission, enemy force movements can be compared to the predictions. By using enemy force movement predictions for an initial comparison, the enemy force movements may only need to be compared to the own force mission plan if the enemy forces deviate from the predictions. When enemy force movement deviates from the predictions, new enemy force movement predictions can be generated. The new enemy force movement predictions can then be compared to the own force mission plan to determine if a route re-plan is needed. The route can be re-planned to determine a route that reduces or eliminates the chance of a lethal encounter with an enemy or threat.

1. A route re-planning system comprising: a processor disposed onboard a vehicle and coupled to a non-transitory computer readable medium bearing software instructions that, when executed by the processor, cause the processor to perform operations including:receiving an original mission plan and threat location data at the processor;comparing the threat location data for a threat to a stored time/space threat threshold corresponding to the threat, the stored time/space threshold including a threshold geographical area boundary, and determining, based on the comparison, whether a moving threat location has moved outside or moved within the threshold geographical area boundary;when the threat location has moved within the threshold geographical area boundary, the original mission plan including an original route for the vehicle is maintained; andwhen the threat location has moved outside the threshold geographical area boundary, assessing the impact of the threat moving outside the threshold geographical area boundary,wherein the threat location data is obtained from a common operational picture database or a sensor system. 2. The system of claim 1, wherein the threat location data is received wirelessly at the vehicle from a location remote from the vehicle during execution of the original mission plan. 3. The system of claim 1, wherein the assessing the impact of the threat moving outside the corresponding time/space threat threshold comprises: assessing own force survivability and generating a reflexive response signal when own force is in immediate danger;generating, with the processor, new threat movement predictions;performing an updated multi-point survivability analysis with the processor using the new threat movement predictions as input, the multi-point survivability analysis including generating a new time/space threshold for the threat at each of a plurality of predetermined time in a mission timeline and including determining the lethality of a threat at a plurality of locations;determining, with the processor, whether a current mission plan is survivable based on the updated multi-point survivability analysis; andwhen the original mission plan is not survivable, generating a new mission plan including a re-planned route for the vehicle, the re-planned route being a different route than the original route associated with the original mission plan. 4. The system of claim 3, wherein the operations further include generating a warning display within the vehicle in response to the reflexive response signal. 5. The system of claim 1, wherein the original mission plan is generated by the processor according to a series of operations performed by the processor, the operations including: predicting initial threat movements;performing an initial multi-point survivability analysis using the initial threat movement predictions as input, the initial multi-point survivability analysis including generating the stored time/space threshold for the threat at each of a plurality of predetermined times in the original mission timeline and including determining the lethality of a threat at a plurality of locations; andgenerating the original mission plan including the original route for the vehicle. 6. The system of claim 1, wherein the threat location data is obtained from the sensor system and the common operational picture database. 7. A computerized method for route re-planning, the method comprising: comparing, by a processor programmed to perform route re-planning, threat location data for a threat to a stored time/space threat threshold corresponding to the threat, the stored time/space threshold including a threshold geographical area boundary, and determining, based on the comparison, whether a moving threat location has moved outside or moved within the threshold geographical area boundary;maintaining a current mission plan including a current mission route for the vehicle when a threat location has moved within the corresponding time/space threat threshold; andwhen the threat location has moved outside the corresponding time/space threat threshold, assessing the impact of the threat moving outside the corresponding time/space threat threshold. 8. The computerized method of claim 7, wherein the assessing the impact of the threat moving outside the corresponding time/space threat threshold comprises: assessing survivability of the current mission plan; andwhen the current mission plan is not survivable, generating a new mission plan including a re-planned mission route. 9. The computerized method of claim 7, wherein the assessing the impact of the threat moving outside the corresponding time/space threat threshold comprises: generating, with the processor, new threat movement predictions;performing an updated multi-point survivability analysis with the processor using the new threat movement predictions as input;determining, with the processor, whether the current mission plan is survivable based on the updated multi-point survivability analysis; andwhen the current mission plan is not survivable, generating a new mission plan including a re-planned mission route. 10. The method of claim 7, wherein the mission plan is generated by the processor according to a series of operations performed by the processor, the operations including: predicting initial threat movements;performing a multi-point survivability analysis; andgenerating an initial mission plan including a route. 11. The method of claim 10, wherein the multi-point survivability analysis and the updated multi-point survivability analysis include determining the lethality of a threat at a plurality of locations. 12. The method of claim 10, wherein performing the multi-point survivability analysis and the survivability analysis includes generating time/space thresholds for each threat at each of a plurality of predetermined times in a mission timeline. 13. A non-transitory computer-readable medium having software instructions stored thereon that, when executed by a processor, cause the processor to perform operations comprising: maintaining a current mission plan including a current route for a vehicle when a threat location has moved within a corresponding time/space threat threshold, the time/space threat threshold including a threshold geographical area boundary; andwhen the threat location has moved outside the corresponding time/space threat threshold, assessing the impact of the threat moving outside the corresponding time/space threat threshold,wherein threat location data is obtained from a common operational picture database or a sensor system. 14. The non-transitory computer-readable medium of claim 13, wherein the assessing the impact of the threat moving outside the corresponding time/space threat threshold comprises: generating, with the processor, new threat movement predictions;performing an updated multi-point survivability analysis with the processor using the new threat movement predictions as input;determining, with the processor, whether the current mission plan is survivable based on the updated multi-point survivability analysis; andwhen the current mission plan is not survivable, generating a new mission plan including a re-planned mission route. 15. The non-transitory computer-readable medium of claim 13, wherein the operations further comprise: assessing, with the processor, own force survivability and generating a reflexive response signal when own force is in immediate danger. 16. The non-transitory computer-readable medium of claim 13, wherein the mission plan is generated by the processor according to a series of operations performed by the processor, the operations including: predicting initial threat movements;performing a multi-point survivability analysis; andgenerating a mission route. 17.
