The U.S. Department of Homeland Security (DHS) is responsible for protecting and enhancing the
resilience of much of the Nation’s critical infrastructure. Although developments are evolving rapidly
across all domains, the air domain has become increasingly complex in recent years given the proliferation
of the unmanned aircraft system (UAS). In particular, consumer demand and benefits from commercial
and private interests for the small UAS (sUAS)—weighing less than 55 pounds (lbs.) and operating at no
more than 400 feet above ground—have caused expansion of both sUAS and counter-UAS markets. With
new producers vying for market shares, competition is fostering rapidly decreasing prices and innovative
technological features intended to garner a comparative advantage.
