The Chesapeake Bay Detachment (CBD) covers 157.6 acres contiguous to the Chesapeake Bay with a 0.75-mile waterfront. It is located in a relatively clear area away from congestion and industrial interference. The facility maintains towers for antenna support and a ship motion simulator. Off-site facilities include a 2.6-acre site with a 75-ft tower located 10 nautical miles east at Tilghman Island, Maryland, and small‑craft berthing located in the town of Chesapeake Beach, 2 nautical miles north of the main site. Because of its location high above the Chesapeake Bay, unique experiments using low clutter and generally low background radar can be performed at CBD in conjunction with the Tilghman Island site.
