A system (100) for providing an integrated multi-sensor detection and countermeasure against commercial unmanned aerial systems/vehicles (44) and includes a detecting element (103, 104, 105), a tracking element (103,104, 105) an identification element (103, 104, 105) and an interdiction element (102). The detecting element detects an unmanned aerial vehicle in flight in the region of, or approaching, a property, place, event or very important person. The tracking element determines the exact location of the unmanned aerial vehicle. The identification/classification element utilizing data from the other elements generates the identification and threat assessment of the UAS. The interdiction element, based on automated algorithms can either direct the unmanned aerial vehicle away from the property, place, event or very important person in a non-destructive manner, or can disable the unmanned aerial vehicle in a destructive manner. The interdiction process may be over ridden by intervention by a System Operator/HiL.
