U.S. Army's blimp-like airships get East Coast test

MIDDLE RIVER, Md. (AP) - The Army showed off a blimp-like airship Wednesday that is designed to help the military detect and destroy cruise missiles speeding toward the nation's capital or other major East Coast cities.

The radar-toting vehicle will be launched next week as part of a three-year test of the system at Aberdeen Proving Ground, about 25 miles northeast of Baltimore.

When fully deployed next spring, the system will feature two, unmanned, helium-filled aerostats, tethered to concrete pads 4 miles apart. They'll float at an altitude of 10,000 feet, about one-third as high as a commercial airliner's cruising altitude.

One balloon will continuously scan in a circle from upstate New York to North Carolina's Outer Banks, and as far west as central Ohio. The other will carry precision radar to help the military on the ground to pinpoint targets.
