Critical infrastructure doesn't look like a target, but it operates like one. Power grids, pipelines, port logistics, and air traffic control all depend on precise GPS timing and wireless communications. A single sustained GPS outage would cost the U.S. economy an estimated $1.6 billion per day. And the threat is no longer theoretical: GPS jamming in the Strait of Hormuz has disrupted commercial shipping across global supply chains. High-tech thieves are deploying Wi-Fi jammers to defeat security systems. The same vulnerabilities that exist on the battlefield exist in every port, grid, and pipeline operations center.
