Lockheed Martin says it has a "field-tested" system for detecting and countering threats from unmanned aircraft systems (UAS). At the Assn. of the U.S. Army’s annual convention in Washington, D.C., this week, the company said it developed the system, called Icarus, to address "an increase in the use of commercially available UAS platforms for surveillance and weaponization." It claimed Icarus "can detect, recognize and counteract these systems with pinpoint accuracy," adding the system "has been field tested and demonstrated to several domestic and international customers over the past year." According to the company, Icarus was developed through internal investment and "combines advanced cyber and cyber electromagnetic activity experience with sensor technology and non-kinetic techniques."
