The base's indoor flight lab is called the "microaviary," and for good reason. The drones in development here are designed to replicate the flight mechanics of moths, hawks and other inhabitants of the natural world. "We're looking at how you hide in plain sight," said Greg Parker, an aerospace engineer, as he held up a prototype of a mechanical hawk that in the future might carry out espionage or kill.

A giant blimplike spy balloon, called an aerostat, keeps an eye on insurgent activity in Afghanistan. The helium-filled aerostats are the largest in the drone arsenal. They are tethered to the ground by cables and float 15,000 feet in the air. An attached camera pans 360 degrees for constant, real-time surveillance as far as 30 miles away. There are now more than 60 aerostats in Afghanistan, with double that number expected in the next year.
From blimps to bugs, an explosion in aerial drones is transforming the way America fights and thinks about its wars. Predator drones, the Cessna-sized workhorses that have dominated unmanned flight since the Sept. 11, 2001, attacks, are by now a brand name, known and feared around the world. But far less widely known are the sheer size, variety and audaciousness of a rapidly expanding drone universe, along with the dilemmas that come with it.
