Without going over too much ground it would be worth while reading Wired for War - Peter Singer.
The military’s unblinking eye in the sky, which keeps watch over operations in Iraq, Afghanistan and Pakistan, is about to get even beadier. A new multi-camera sensor the U.S. Air Force is adding to its killer spy drones will exponentially broaden the area troops can monitor, and the technology lets a dozen users simultaneously grab different slices of the image. Called the Gorgon Stare, it represents the next big step in unmanned combat aircraft. Two MQ-9 Reapers retrofitted with the new $15 million wide-area aerial surveillance sensors, or WAAS, will fly test missions later this year, and the Air Force plans to have ten such planes in battle by next spring, in rotation on a 24/7 patrol. “It’s an incredible force enhancer,” said Colonel Eric Mathewson, Director of the service’s Unmanned Aircraft Systems Task Force at the Pentagon. Sierra Nevada Corporation, makers of the WAAS, chose the name, a spooky reference to the cursed sisters from Greek mythology—Medusa being the Beyoncé of the trio—whose gaze turned men to stone.
