harbor defense unit ,little creek VA

The Harbor Defense Unit, Little Creek, VA, was established to protect the vital maritime approaches to the Norfolk and Hampton Roads area, one of the United States' most significant naval complexes. Activated during World War II, its mission included operating coastal artillery, anti-aircraft batteries, and later, radar and underwater detection systems to guard against enemy ships, submarines, and aircraft. The unit worked closely with the U.S. Navy’s amphibious forces at the Little Creek Amphibious Base, providing critical security for troop embarkation and supply operations. Over time, as threats and technology evolved, the Harbor Defense Unit adapted its role, eventually integrating into broader coastal defense and homeland security missions.
