"The space-based Global Positioning System (GPS) signal that guides smart bombs and cruise missiles to their targets underpins U.S. technological superiority on the battlefield. Yet because it is relatively easy to jam, it is also the Achilles' heel of U.S. military might. Although the integrity of the GPS signal was maintained in the war with Iraq, enemy attempts to corrupt it underscored the need to protect GPS-dependent weapons and navigation systems. Against a more capable enemy, GPS might find itself among the first casualties of any new conflict."
