Lying amidst rolling sand dunes at Cape Henlopen State Park, on a high bank overlooking the Atlantic Ocean, is the Fort Miles Historical Area, a former World War II military base that was a key piece of our nation's coastal defense from World War II through the early 1970’s. Today, Fort Miles is home to the Fort Miles Museum, encompassing a gun battery, six barracks buildings, a fire control tower, an orientation building, and an artillery park.
The history of Fort Miles exemplifies America’s call to action to stem the tide of war against German invasions along the Atlantic Seaboard that, at the onset of World War II, appeared virtually unstoppable. The gun batteries of Fort Miles, secret state-of-the-art installations built within the massive sand dunes of Cape Henlopen, were designed to defend against the powerful German navy.
With more than 2,500 soldiers stationed on high alert, the heavy guns, mine fields, and searchlights of Fort Miles defended the vital trade centers of Wilmington, Philadelphia, and beyond. As America moved into the cold war, the role of Fort Miles shifted to highly classified missions defending against the threat of Soviet submarine operations off our coastline.
Fort Miles is a special place for history enthusiasts, veterans, families, or anyone interested in learning about Delaware stories, Delaware heroes, and Delaware’s role in WWII. Take a guided tour, enjoy an interpretive program, visit the art gallery, take in a special event, and celebrate "The Greatest Generation."

In 1962, the U.S. Navy took control of a portion of the southern end of Fort Miles, including Batteries Smith and Herring, to establish Naval Facility Lewes (NAVFAC Lewes), a Sound Surveillance System (SOSUS) shore terminal. The terminus had been at Cape May, New Jersey until damaged in the "Ash Wednesday" Storm and that station's equipment had been shipped across to Fort Miles by a Navy Landing Ship, Tank (LST). The Terminal Building was at Battery Herring with administration and barracks facilities further north. The array was reconnected at Lewes by the cable ship Neptune. NAVFAC Lewes would continue to operate until 30 September 1981. Since the SOSUS program was not officially declassified until 1991, the actual operations of NAVFAC Lewes remained classified for the duration of the facility's existence.[25] The headquarters building that also contained some quarters, eating and recreation facilities, became a Naval Reserve Center until all land was returned to the state in 1996. That building remains as the Biden Environmental Conference Center. A married housing complex became facilities for the University of Delaware College of Earth, Ocean and Environmental Sciences.
