Unmanned aircraft systems (UAS)—from hobbyist quadcopters to high-altitude, military-grade drones—are providing adversaries with a new opportunity for tactical advantage and pose a serious threat to U.S. and allied troops on the battlefield. Outfitted with cameras, sensors, laser designators, radio frequency collection devices, and even munitions, UAS can be deployed to perform reconnaissance and surveillance; provide forward air control; or attack our ground forces, bases of operation, vehicles, local infrastructure, and other military targets—creating fear and havoc on the ground below. And the rapid commercialization of UAS has made them inexpensive and readily available—even to small, poorly resourced adversaries.
Compounding the threat, their relatively small size, composite materials, small radar and electromagnetic signatures, and quiet operation make UAS very difficult to detect, track, and defeat by traditional means. Continued technological advances to UAS are expected to make them even more deadly and more difficult to defend against.
