The U.S. Army’s Coast Artillery Corps defended the United States against naval attack with fixed gun defenses located around major deep-draft harbors.
Seacoast Harbor Defense Fortifications: gun batteries, fire control stations, communications bunkers, wharves, searchlights, and minefield control structures.
Garrison Buildings: enlisted barracks, officers quarters, hospitals, post exchanges, bakeries, power plants, and ordnance & supply storage buildings.
