The proposed program offers an innovative approach for protecting a battle group from attacks by advanced anti-ship missiles. Spatially distributed countermeasures, of various types, are deployed in a coordinated manner so as to counter all phases and aspects of threat missile weapon systems. These coordinated countermeasures techniques are applied sequentially and their effectiveness against each attacking missile is continuously evaluated during the engagement. In the event that the final countermeasure (on-board ECM) is not successful in defeating a missile, an alert is provided in time for hard-kill weapons to be deployed. This alert is made possible by a proprietary method for predicting, in advanced real-time, the terminal flight path of an attacking missile being countered by ECM. The end product of this program will be a preliminary design for a soft-kill defense network which utilizes advanced coordinated countermeasures techniques from spacially distributed platforms and devices that are under the direction of a countermeasures controller. Preliminary analysis, included in this proposal, indicates that the system will defeat over 99% of all attacking anti-ship missiles.
