Strategic (High Altitude) EMP

A large-scale electromagnetic pulse generated by a nuclear detonation or specialized device at high altitudes—typically 30 to 400 kilometers above Earth’s surface. These EMPs are capable of affecting vast geographic regions, potentially disabling national power grids, satellite systems, long-haul fiber networks, and all unshielded electronic infrastructure. As a strategic weapon, high-altitude EMPs represent a catastrophic threat to the continuity of broadband communications and critical national infrastructure across civilian and military domains.
