The U.S. Navy uses the lower Potomac as a testing range for its projectiles. The Naval Surface Weapons Center operates the Dahlgren Facility, a large research and development center at the Virginia side of the 301 bridge. The site is home to the Naval Space Command, the AEGIS Training Center, and the Naval Space Surveillance System. Tours are available by appointment.

NOAA maintains a buoy near the Dalhgren Facility below the Nice-Middleton Bridge. Data is collected by NOAA and made available for education and navigation. Current data is shown below.
