Abstract
Abstract An active defense system against ballistic missiles. The system includes a fleet consisting of a plurality of flying platforms fitted with interceptor missiles which loiter over hostile territory. The flying platforms communicate with each other by suitable data links and at least some of them also communicate with a ground station located in friendly territory. The interceptor missiles have electro-optical seeking and tracking capabilities and the data which the missile generates while in captive flight are communicated to a processor of the associated flight platform for autonomous decision whether to launch or not to launch the missile.
