“But when it’s dogfighting you have to figure out, O.K., if I’m in a thirty-degree bank angle, ascending at twenty degrees, how much do I have to pull the stick to get to a forty-degree bank angle, rising at ten degrees?” And, because flight is three-dimensional, speed matters even more. “Most of the time, a plane flies straight and level,” Phil Chu, an electrical engineer who serves as a science adviser to the ACE program, explained.
A plane flies differently at varying altitudes and angles, on hot days versus cold ones, or if it’s carrying an extra fuel tank or missiles. But a dogfighting algorithm will have to take into account both the environment and the aircraft.
Like self-driving cars, autonomous planes use sensors to identify discrepancies between the outside world and the information encoded in their maps. If any one of them gets shot down, it’s not as big of a deal.”Īll told, the L-39 was taken up above Lake Ontario twenty times, each sortie giving the engineers and computer scientists the information they need to build a model of its flight dynamics under various conditions. DARPA calls this “mosaic warfare.” In the case of aerial combat, Pettyjohn said, “these much smaller autonomous aircraft can be combined in unexpected ways to overwhelm adversaries with the complexity of it. In other words, fewer humans and more expendable machines. Stacie Pettyjohn, the director of the Defense Program at the Center for a New American Security, told me that the ACE program is part of a wider effort to “decompose our forces” into smaller, less expensive units. According to the agency’s Strategic Technology Office, a fighter jet with autonomous features will allow pilots to become “battle managers,” directing squads of unmanned aircraft “like a football coach who chooses team members and then positions them on the field to run plays.” will fly the plane in partnership with the pilot, who will remain “in the loop,” monitoring what the A.I. But the objective of the ACE program is to transform a pilot’s role, not to remove it entirely. Paul Schifferle, the vice-president of flight research at Calspan, the company that’s modifying the L-39 for DARPA, said, “The dogfight is probably the most dynamic flight profile in aviation, period.”Ī fighter plane equipped with artificial intelligence could eventually execute tighter turns, take greater risks, and get off better shots than human pilots. But few aspects of warfare are as complex as aerial combat.
And a number of current military technologies, such as underwater mine detectors and laser-guided bombs, are autonomous once they are launched by humans. The first autopilot system, which involved connecting a gyroscope to the wings and tail of a plane, débuted in 1914, about a decade after the Wright brothers took flight. Artificial intelligence is being designed to improve supply logistics, intelligence gathering, and a category of wearable technology, sensors, and auxiliary robots that the military calls the Internet of Battlefield Things.Īlgorithms are already good at flying planes. The Navy is building unmanned vessels that can stay at sea for months the Army is developing a fleet of robotic combat vehicles. This year, the Pentagon plans to spend close to a billion dollars on A.I.-related technology. The exercise was an early step in the agency’s Air Combat Evolution program, known as ACE, one of more than six hundred Department of Defense projects that are incorporating artificial intelligence into war-fighting. Engineers on the ground, under contract with DARPA, the Defense Department’s research agency, had choreographed every turn, every pitch and roll, in an attempt to do something unprecedented: design a plane that can fly and engage in aerial combat-dogfighting-without a human pilot operating it. For two hours, the pilot flew counterclockwise around the lake. The bay in front of the cockpit was filled with sensors and computer processors that recorded the aircraft’s performance. The plane, which bore the insignia of the United States Air Force, was a repurposed Czechoslovak jet, an L-39 Albatros, purchased by a private defense contractor.
On a cloudless morning last May, a pilot took off from the Niagara Falls International Airport, heading for restricted military airspace over Lake Ontario. This content can also be viewed on the site it originates from.
