Drones are shrinking

Highlight Story

Two miles from the cow pasture where the Wright Brothers learned to fly the first airplanes, military researchers are at work on another revolution in the air: shrinking unmanned drones, the kind that fire missiles into Pakistan and spy on insurgents in Afghanistan, to the size of insects and birds.

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.

Half a world away in Afghanistan, Marines marvel at one of the new blimplike spy balloons that float from a tether 15,000 feet above one of the bloodiest outposts of the war, Sangin in Helmand Province.

The balloon, called an aerostat, can transmit live video — from as far as 20 miles away — of insurgents planting homemade bombs. 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 September 11, 2001, attacks, are by now a brand name, known and feared around the world. http://www.hindustantimes.com/Images/HTEditImages/Images/21_06_11-metro-19b.jpg

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.

The Pentagon now has some 7,000 aerial drones, compared with fewer than 50 a decade ago.

Within the next decade the Air Force anticipates a decrease in manned aircraft but expects its number of “multirole” aerial drones like the Reaper — the ones that spy as well as strike — to nearly quadruple, to 536.

Peter W. Singer, a scholar at the Brookings Institution and the author of Wired for War, a book about military robotics, calls them “bugs with bugs.”

In recent months drones have been more crucial than ever in fighting wars and terrorism.

The Central Intelligence Agency spied on Osama bin Laden’s compound in Pakistan by video transmitted from a new bat-winged stealth drone, the RQ-170 Sentinel, otherwise known as the “Beast of Kandahar,” named after it was first spotted on a runway in Afghanistan.

More than 1,900 insurgents in Pakistan’s tribal areas have been killed by American drones since 2006, according to the website www.longwarjournal.com.

Large or small, drones raise questions about the growing disconnect between the American public and its wars.

Military ethicists concede that drones can turn war into a video game, inflict civilian casualties and, with no Americans directly at risk, more easily draw the United States into conflicts.

Drones have also created a crisis of information for analysts on the end of a daily video deluge. Not least, the Federal Aviation Administration has qualms about expanding their test flights at home, as the Pentagon would like.

Within the military, no one disputes that drones save American lives.

Many see them as advanced versions of “stand-off weapons systems,” like tanks or bombs dropped from aircraft, that the US has used for decades.
