Since the United States military campaign began in Afghanistan, the unmanned spy plane has gone from a bit player to a starring role in Pentagon planning. Rather than the handful of “autonomous vehicles,” or A.V.’s, that snooped on Al Qaeda hideouts, commanders are envisioning wars involving vast robotic fleets on the ground, in the air and on the seas — swarms of drones that will not just find their foes, but fight them, too.

But such forces would need an entirely new kind of network in which to function, a wireless Internet in the sky that would let thousands of drones communicate quickly while zooming around a battle zone at speeds of up to 300 miles an hour. Such a network would have to be able to deal instantaneously with the unpredictable conditions of war and cope with big losses.
