Get Ready for a New Generation of Drones

The high-tech robots are getting smaller, deadlier and more autonomous

Today's unmanned robotic planes only seem advanced. A decade after the CIA and the Air Force tucked a Hellfire missile under the wing of a Predator drone, much hasn't actually changed: pilots in air-conditioned boxes remotely control much of the armed drone fleet; the robo-planes are easy for an enemy to spot; the weapons they fire weigh about the same; as much as they love the skies, they take refuge on dry land; and they're built around traditional airframes like planes and helicopters. Yawn.

All this is starting to change. Drones are moving out to sea—above it and below it. They're growing increasingly autonomous, no longer reliant on a pilot with a joystick staring at video feeds from their cameras. They're getting stealthier; the payloads they carry are changing; and they're going global. They're pushing humans out of the gondolas of blimps. And the laboratories of the drones of the future aren't only owned by American defense contractors, they're in Israel and China and elsewhere, too.
