Systems and methods countering an unmanned air vehicle

SYSTEMS AND METHODS COUNTERING AN UNMANNED AIR Systems (100) and methods for countering an unmanned air vehicle are disclosed. Representative methods include directing an interceptor UAV (110) toward a target UAV (199), and directing the interceptor UAV (110) back to ground along a controlled flight path, for example, in response to an instruction not to engage with the target UAV (199), and/or in response to an unsuccessful engagement. Another representative method includes disabling the target UAV (199) by deploying a disabling element (e.g., a net) from the interceptor UAV (110) to contact the target UAV. Representative systems (100) include a target acquisition system (101), a launch control system (102), and an engagement system (140) carried by the interceptor UAV (110). In particular embodiments, the interceptor UAV (110) can have a generally cylindrical fuselage (112), one or more fins (114) carried by the fuselage, counter-rotating propellers (121 a, 121b) carried by the fuselage (112), and a disabling system (150) that is configured to disable the target UAV (199).
