SYSTEMS AND METHODS FOR COUNTERING AN UNMANNED AIR VEHICLE

Systems and methods for countering an unmanned air vehicle are disclosed. Representative systems include an interceptor UAV for disabling a target UAV, the interceptor UAV comprising: a flight vehicle having: a cylindrical fuselage elongated along a fuselage axis; four fins carried by the fuselage and arranged in a cruciform, each fin having a fin slot extending from the fuselage in an outboard direction transverse to the fuselage axis; a propulsion system that includes: a first propeller carried by the fuselage and rotatable about the fuselage axis in a first direction to sequentially pass in and out of successive fin slots; a second propeller carried by the fuselage and rotatable about the fuselage axis in a second direction opposite the first direction to sequentially pass in and out of the successive fin slots; a power source carried by the fuselage, the power source including a first electric motor coupled to the first propeller to rotate the first propeller in the first direction, and a second electric motor coupled to the second propeller to rotate the second propeller in the second direction; and a stored electrical energy source coupled to the first and second electric motors; at least one control surface carried by at least one of the fins; a guidance system coupled to the at least one control surface; and a deployable net carried by the flight vehicle and having a first, inactive mode and a second, active mode, wherein in the second mode, the deployable net is deployed from the flight vehicle to disable the target UAV. Representative methods include directing an interceptor UAV toward the target UAV; and disabling the target UAV by deploying a disabling element from the interceptor UAV to contact the target UAV.
