Nets and high-tech hijackings: Anti-drone systems offer new ways to counter rising threats
By DAVID KLEPPER
WASHINGTON (AP) — Drones have harassed airports and bedeviled local police. They have trespassed over nuclear plants and prisons. On the battlefield, they can kill.
But aside from shooting down the devices, which may create further danger, there’s often not much anyone can do to stop drones when they pose a threat or wander where they’re not welcome.
That’s beginning to change. Cheap and easily modified, unmanned aerial vehicles have become a part of daily life as well as a tool for governments and bad actors alike — used for intelligence gathering, surveillance, sabotage, terrorism and more. Concerns about their misuse have spurred a technological scramble for ways to stop the devices in midair.
“An adversary can use an off-the-shelf drone they bought for $500 and find out what’s going on at U.S. nuclear weapons bases,” said Zachary Kallenborn, a London-based national security consultant and expert on drone warfare. “China, Russia, Iran: If they’re not doing it they’re stupid.”
