Military uses

Up in the air

Drones will change war—and more


Mar 29th 2014 | From the print edition







AMERICA’S DECADE OF misbegotten war in the early 21st century will be remembered for many things, but when it comes to technology, the rise of the drone will stand out. When America invaded Iraq in 2003, it had a couple of hundred; by the time it left, it had almost 10,000.

Pilotless aircraft had been around for decades. What was new was that, thanks to the Global Positioning System (GPS), they knew where they were, and thanks to better satellite and other communications links they could send back copious data. That allowed them to feed intelligence, surveillance and reconnaissance (ISR) to all levels of America’s increasingly information-hungry armed forces. A platoon of soldiers wanting to look beyond the building in front of them; an intelligence agency tracking a target; a general staff trying to understand what was going on across a broad area: today there is a drone for them all.

Throughout this entire period no drone, or indeed any other robot, was put through the full qualification process usually required for any new American weapons. They were sent into the field in various stages of unreadiness by people who saw a need for them. On the ground that need was dealing with bombs; in the air it was almost entirely ISR.

A very small number were used for launching attacks, both on the battlefield and off it, often in countries—Pakistan, Yemen, Somalia—with which America was not at war. Most of these attacks were carried out by the CIA, which is not new to killing people it has identified as enemies; its Operation Phoenix was responsible for the death of tens of thousands in South Vietnam in the 1970s. But drones allowed such tactics to be employed much farther away from any logistical support, and allowed decisions on whom to kill to be made far higher up the tree.

A small number of drones designed to fire missiles thus allowed new strategies to be adopted in the “global war on terror”—an example of how a relatively minor technological advance can have big consequences. Military drones, after all, are no cleverer than doornail-dumb earthbound robots; many are dumber still. They can do more because they operate in a much less difficult environment, with few obstacles in the way and most of the tasks achieved by pointing a camera or a missile in the right direction. The smart ones can follow commands such as “stay where you are,” “follow this flight plan” or “come home and land”; if their communications are cut off, some will return to the place where they last received a command. But humans are always involved in any tricky or lethal decisions.

That may change. Some military planners see a big future for drones—and for robots both on land and at sea—which will do a lot more than just provide ISR. The more drones that the armed forces deploy, the greater the pressure for autonomy becomes. One reason is cost: a drone that needs minimal supervision is a lot cheaper to operate than one that needs detailed attention. The other is safety. The greater your reliance on drones, the more your enemies will want to attack them. The drones’ command, control and communications network will become an important target. More autonomous drones are less vulnerable to such attack.

Not the drones you are looking for

Many people are alarmed by the idea that new forms of warfare will lead to increasingly deadly autonomous weapons, not just drones but also smart undersea systems. Various human-rights organisations have banded together in a “Campaign to Stop Killer Robots” which seeks to ban fully autonomous weapons systems. The Convention on Certain Conventional Weapons, responsible for previous bans on laser blinding weapons and some types of explosives, will begin discussing such a ban in Geneva in May.

Some military lawyers claim that most of what the campaigners hope a ban would outlaw is in fact already illegal under existing rules of war, which forbid indiscriminate attacks; and for some purposes, such as defending ships against missile attacks, autonomous systems are both necessary (because of their speed of response) and legally and morally unproblematic, since they operate in areas where no civilians, and possibly no enemy combatants either, will be affected.



Once again, responses to robots reflect broader worries about technology. The idea that technology makes war too easy and removes its reliance on soldierly virtues goes far beyond concerns about the specific roles that robots might play. It is shared by a significant number of military men, who consider killing people a serious matter. Many would be deeply uneasy about delegating it. They have no problem with robots that may save the lives of their comrades—working on bomb disposal, looking round a corner into the unknown and perhaps in future evacuating the wounded from the battlefield. But robots that might replace those comrades (or, in an enemy’s hands, threaten them directly) are seen as much more troubling.

That may be one reason why, surprisingly, the Pentagon’s robot budget is currently shrinking. In its 2014 budget request unmanned systems’ funding was down by a third on the previous year. With ever fewer soldiers in combat zones, there is less need for bomb disposal and the like; but the money for both buying drones and developing better ones is scarce, too. Some, especially in the air force, never much cared for them anyway and are happy to make them a lower priority. And other programmes—most notably the extraordinarily expensive F-35 fighter plane—have far more effective champions in the military-industrial-congressional complex than drones do. At a recent meeting on autonomous weapons, a retired American colonel suggested that for the next decade or so there is no need to worry about America getting new drone capabilities because it will not get any new drones, period.

Mark Gunzinger, another retired colonel, now at CBSA, a Washington think-tank, worries about that. By not developing newer, better drones, he says, the armed forces risk missing opportunities for big improvements in their capabilities. Take aircraft carriers, whose ability to project force is fundamental to America’s global military strategy. Close to the coast of a sophisticated adversary, they are increasingly at risk of missile attack. If they had bomb- and missile-carrying drones on board, they might be able to strike from greater distances. An experimental American drone, the X47B, has shown that it can take off from and, more impressively, land on carriers. But there is currently no programme to develop that capability to allow carriers to attack well-defended targets on land from a safe distance at sea. That would require drones to be able to overcome enemy defences, which the present generation cannot do.

A deeper worry is that potential adversaries will themselves push ahead with drones, perhaps finding entirely new ways of using them en masse. Low-cost computing power has especially benefited drones that use a number of rotor blades for their lift; co-ordinating many rotors takes quite a lot of computing, but makes take-off and landing much easier. “Quadcopters” with a range of 10-20km and a battery life of half an hour are now mass-produced and can cost less than $1,000. A recent report on “War in 20YY” by CNAS, another think-tank, points out that the ability to blacken a town’s sky with a swarm of such gadgets, or send a wave of them across a sea, could produce completely new tactical possibilities; it might be the sort of technological development which changes how wars are won.

Drones will get cheaper still, in part because markets for them are opening up quickly. In America there is as yet no legal framework permitting their commercial use; elsewhere they are being used by journalists, for safety checks and—as in America—for fun. The Federal Aviation Administration is drawing up a regime for commercial use in the country’s air space from 2015.

Most of those uses, to begin with, will probably be in the civilian equivalent of ISR, both by government bodies such as police departments (of which America has 20,000) and by private entities. Chris Anderson, a former writer on this newspaper and now the boss of 3D Robotics, which makes drones, says they supply that fashionable commodity, big data, to fields where it is otherwise hard to come by, such as agriculture. Mr Anderson’s company, along with others, wants to enable “alpha farmers”—free-spending, tech-friendly innovators committed to coming up with the highest-quality produce—to keep an eye on their crops more or less plant by plant and hour by hour. When they have worked out what to do with such data, the rest of the industry may follow. Another use could be checking up on infrastructure such as roads, pipelines and transmission lines.



Peter Singer of the Brookings Institution in Washington, DC, who has written extensively on drone warfare, draws an analogy with military aviation to show how far drones have yet to go. At the beginning of the first world war, military aviation was largely concerned with reconnaissance. It grew quickly, taking on new roles with specialised bombers and fighters, and by 1918 there were tens of thousands of warplanes. Men like Billy Mitchell, Hugh Trenchard and Giulio Douhet started to argue that aircraft could fundamentally change warfare. The planes went on to do so, though not quite in the way that those air-power visionaries imagined.



For Mr Singer, the interesting part is what military aircraft in the first world war did not do. None of the planes was used for transmitting messages, moving cargo and people or spraying crops—the uses to which aircraft would be put in their hundreds of thousands over the next few decades. Today’s military drones are a little more diversified. Whereas most of them look and some kill, others are used for logistics or communications. But as they become more capable and the rules are relaxed, those other capabilities will come into their own beyond the battlefield.
