With a strategic location and the deepest harbor on the U.S. East Coast location, Charleston has benefited from a significant military presence since its founding in 1670. The Charleston region is home to Joint Base Charleston, one of twelve joint facilities operated by the Department of Defense; the Naval Information Warfare Center (NIWC), one of the Navy’s only two cyber mission engineering centers; and nearly all U.S. Dept. of Defense and Dept. of Homeland Security agencies.
