defense grid
Coordinated shield system
A defense grid is a network of interconnected defensive installations—radar stations, missile batteries, aircraft, or sensors—designed to detect and respond to threats across a region.
The term appears in military contexts describing national air defense systems and in science fiction depicting force fields or weapon arrays protecting planets or spacecraft: The enemy fleet breached the orbital defense grid.
