All-Seeing Blimp on the Rise

The problem with the American military today is that it doesn't have a giant, robotic airship, two-and-a-half times the size of the Goodyear blimp, that can watch over an entire city at once. Thankfully, the Pentagon's way-out research arm, DARPA, is trying to fix that.
The program is called ISIS, short for "Integrated Sensor Is Structure." And the idea is to park an unmanned airship over a hot zone for a year, at nearly 65,000 feet in the sky. Up there, ISIS can spot enemy soldiers up to 180 miles away, target tanks and trucks, and watch out for incoming cruise missiles 350 miles in the distance -- a "detailed, real-time picture of all movement on or above the battlefield," one DARPA program manager says. During down times, ISIS might even serve as a cell tower in the sky, relaying communications to U.S.
troops.
