Dahlgren Heritage Museum

3549 James Madison Parkway

The Dahlgren Heritage Museum uses exhibits and pictures to tell a powerful story of how a remote testing range, carved out of Potomac River marshland, earned a reputation as an intellectual center for the Navy. The Navy established the Dahlgren base in 1918 and named it for Rear Admiral John A. Dahlgren, the “Father of American Naval Ordnance.” It was the service’s new proving ground for test-firing guns destined for Navy warships. Dahlgren has evolved to encompass a broad range of research and development, training, and military operations critical to the nation’s defense. The research and innovation that have gone into weapons development for almost a century are a key part of the story, but so is the impact of that research on other innovations, like the GPS tracking system we use in our cars.

Open Wed.–Sun., 10 a.m. to 5 p.m. and for special events as announced on the museum website.
