Supersonic Drones Can Outmaneuver Humans. So Why Do We Still Need Pilots?

A QF-16 embarking on its first unmanned flight

The F-16 is familiar to airplane enthusiasts as the nimble American jet fighter, in service since the 1970s, with a nose like a heron with a severe underbite. Last week saw the maiden flight of the QF-16, which is just an F-16 with one modification: no pilot inside.

Drones are everywhere these days, from battlefields to toy stores and music videos, but most are slow, relatively underpowered, and valuable only because they can stay in the air for long periods of time or because they’re cheap. This QF-16, on the other hand, is a drone with an afterburner that can fly at one-and-a-half times the speed of sound. In its first test flight from Tyndall Air Force Base in Florida, the plane executed a barrel roll as well as a “split S”—a (very fun-sounding) move in which the plane flips over onto its back and then does half a loop so it ends up headed, right-way-up, in the opposite direction—before executing a perfect landing back at the base.

Six formerly mothballed F-16’s have been retrofitted into QF-16’s, according to Boeing (BA) spokesperson Michelle Shelhamer, and next week they’ll be flown—by actual pilots sitting inside them—to their new home at Holloman Air Force Base in New Mexico.

It isn’t the first time an old jet fighter has been turned into a remote-control plane. The Air Force has done the same thing to Vietnam-era F-4 Phantoms. Like those older fighters, the QF-16 is going to be used as a target in live-fire training so the Air Force’s human pilots—and eventually, as more come online, those in the Navy and the Army—can get real-world experience in dogfights. In other words, these engineering marvels, rescued from the boneyard, are destined for fiery aerial deaths.

As Shelhamer points out, however, these planes can do everything that a piloted plane can do, if not more: “It’s fully capable and fully functional. It pulls the same altitudes, the same maneuvers.” The QF-16 can pull a 9G turn, which very likely would render a live pilot unconscious. All of which raises the question of why we need pilots at all. Most of the flying in commercial aircraft is already done by computer; when accidents occur in modern aircraft, it’s usually the result of human error, rather than mechanical failure. Will flying a jet soon be one of those activities, like horseback riding and sailing, that were once vital military skills but now are pastimes for the rich?

David Deptula is a retired Air Force lieutenant general, a former F-15 fighter pilot who went on to develop the Air Force’s policy on remotely piloted aircraft (the armed forces’ preferred term for drones). He’s been a vocal proponent of using so-called RPAs for the sort of missions traditionally reserved for manned craft. Still, he doesn’t see pilots being rendered obsolete soon. For complex, fluid situations, even supersonic drones can’t beat a flyboy in the cockpit. “I’ll put a manned aircraft against a remotely piloted aircraft any time,” he says, “and I’ll shoot it down.”

“If you look at a high-threat environment where you’re dealing with surface-to-air threats, air-to-air threats, and trying to simultaneously orchestrate a large number of friendly aircraft in a cohesive fashion, this is something that we have yet to be able to achieve with artificial intelligence or remotely piloted aircraft,” Deptula says. “Maybe we’ll get there someday, but not anytime soon.”

Even then, he adds, there are certain situations where we may be loathe to remove direct, in-situ human control: “Will we want remotely piloted aircraft with nuclear weapons on board?” he asks. “Or how about Air Force One?”
