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 movement prediction system, comprising: a processor coupled to a nontransitory computer readable medium bearing software instructions that, when executed by the processor, cause the processor to perform operations comprising comparing 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,determining, based on the comparison, whether a moving threat location is outside or within the threshold geographical area boundary,maintaining a current mission plan including a current mission route when the moving threat location is in the corresponding time/space threat threshold assessing the impact of the threat moving outside the corresponding time/space threat threshold byperforming an updated multi-point survivability analysis with the processor using the predicted future movement of the threat as input;determining, with the processor, whether the current mission plan is survivable based on the updated multi-point survivability analysis;generating a new mission plan including a re-planned mission route, when the current mission plan is not survivable, andpredicting future movement of the threat based on the moving threat location when the moving threat location is outside of the corresponding time/space threat threshold. 2. The movement prediction system of claim 1, wherein the threat location data is obtained from a common operational picture database or a sensor system. 3. The movement prediction system of claim 1, wherein the new mission plan is generated by the processor according to a series of operations performed by the processor, the operations comprising: predicting initial threat movements;performing a multi-point survivability analysis; andgenerating an initial mission plan including an initial mission route. 4. The movement prediction system of claim 3, wherein the multi-point survivability analysis and the updated multi-point survivability analysis include determining the lethality of the threat at a plurality of locations. 5. The movement prediction system of claim 3, wherein the performing the multi-point survivability analysis and the updated multi-point survivability analysis includes generating time/space thresholds for the threat at different times in a mission timeline. 6. A computerized method of predicting movement of a moving threat, comprising: maintaining, using a processor programmed to perform route re-planning, a current mission plan including a current mission route when the moving threat is located within a corresponding time/space threat threshold, the time/space threat threshold including a threshold geographical area boundary; assessing the impact of the moving threat outside the corresponding time/space threat threshold byperforming an updated multi-point survivability analysis with the processor using the predicted future movement of the threat as input;determining, with the processor, whether the current mission plan is survivable based on the updated multi-point survivability analysis;generating a new mission plan including a re-planned mission route, when the current mission plan is not survivable; andpredicting future movement of the moving threat based on a location of the moving threat when the moving threat is located outside of the corresponding time/space threat threshold. 7. The computerized method of claim 6, further comprising: obtaining threat location data for the moving threat from a common operational picture database or a sensor system. 8. The computerized method of claim 6, wherein the new mission plan is generated by the processor according to a series of operations performed by the processor, the operations comprising: predicting initial threat movements;performing a multi-point survivability analysis; andgenerating an initial mission plan including an initial mission route. 9. The computerized method of claim 8, wherein the multi-point survivability analysis and the updated multi-point survivability analysis include determining the lethality of the moving threat at a plurality of locations. 10. The computerized method of claim 8, wherein the performing the multi-point survivability analysis and the updated multi-point survivability analysis includes generating time/space thresholds for the moving threat at different times in a mission timeline. 11. 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 mission route when a moving threat is located within a corresponding time/space threat threshold, the time/space threat threshold including a threshold geographical area boundary; performing an updated multi-point survivability analysis with the processor using the predicted future movement of the threat as input;determining, with the processor, whether the current mission plan is survivable based on the updated multi-point survivability analysis;generating a new mission plan including a re-planned mission route, when the current mission plan is not survivable; andpredicting future movement of the threat based on a location of the moving threat when the moving threat is located outside of the corresponding time/space threat threshold.
