coastal defenses
Barriers against invasion
Coastal defenses are military fortifications and systems designed to protect a shoreline from enemy attack by sea.
Historically these included forts, gun batteries, and seawalls; modern coastal defenses may incorporate radar, missile systems, and naval patrols.
The term also appears in environmental contexts for structures protecting against erosion and flooding: The town invested in coastal defenses after the hurricane.
