System for intercepting threatening missiles in the form of controllable unmanned light aircraft, comprising: at least one reconnaissance device comprising a sensor means for detecting a light aircraft within a monitoring region and a first interception means for carrying out a combat measure against the threatening missile; an unmanned light defence aircraft, on which a second defence means for carrying out a combat measure against the threatening missile is arranged; a control device, which is functionally linked to the reconnaissance device and the light defence aircraft and is configured to receive sensor signals from the sensor means of the at least one reconnaissance device, on the basis of the received sensor signals, on the basis of a predetermined threat level which describes the probable threat risk from the threatening missile for a region to be protected, and on the basis of a predetermined danger level which specifies whether or not an uncontrolled crash of the threatening missile within a defence region, which is situated within the monitoring region and includes the region to be protected, is acceptable, to generate a control signal and pass it on to the reconnaissance device and the light defence aircraft, wherein the reconnaissance device and the light defence aircraft are each configured, on the basis of the control signal, to carry out an associated combat measure, in such a way that a sequence of combat measures are carried out by means of the first defence means and the second defence means; and a capture net for capturing the crashing threatening missile or for shielding the region to be protected, the capture net being deployable below the threatening missile in terms of the direction of gravity by means of two unmanned light net-carrier defence aircraft (25, 26; 25, 27; 25, 28; 25, 29), which take off and land vertically. at least one reconnaissance device comprising a sensor means for detecting a light aircraft within a monitoring region and a first interception means for carrying out a combat measure against the threatening missile; an unmanned light defence aircraft, on which a second defence means for carrying out a combat measure against the threatening missile is arranged; a control device, which is functionally linked to the reconnaissance device and the light defence aircraft and is configured to receive sensor signals from the sensor means of the at least one reconnaissance device, on the basis of the received sensor signals, on the basis of a predetermined threat level which describes the probable threat risk from the threatening missile for a region to be protected, and on the basis of a predetermined danger level which specifies whether or not an uncontrolled crash of the threatening missile within a defence region, which is situated within the monitoring region and includes the region to be protected, is acceptable, to generate a control signal and pass it on to the reconnaissance device and the light defence aircraft, wherein the reconnaissance device and the light defence aircraft are each configured, on the basis of the control signal, to carry out an associated combat measure, in such a way that a sequence of combat measures are carried out by means of the first defence means and the second defence means; and a capture net for capturing the crashing threatening missile or for shielding the region to be protected, the capture net being deployable below the threatening missile in terms of the direction of gravity by means of two unmanned light net-carrier defence aircraft (25, 26; 25, 27; 25, 28; 25, 29), which take off and land vertically.
