Project Description

National Museum of Intelligence and Special Operations


The National Museum of Intelligence and Special Operations is a collaboration between World War II’s Office of Strategic Services (OSS), and the U.S. intelligence and special operations communities to educate the American public about the importance of strategic intelligence and special operations to the preservation of freedom with an aspiration to inspire future generations to serve their country. This project entails the new museum on an 8-acre site in Loudoun County, Virginia, just three and one-half miles north of Dulles International Airport.

Inspired by the OSS’s spearhead insignia, which is a proud representation of U.S. intelligence and special operations dating back to World War II, the site design physically expresses the spearhead in the landscape, creating a striking landmark that is visible on the ground and by air.

Greenway Engineering provided engineering consulting services for site plan design and construction administration. The 52,000 SF museum includes vibrant exhibition and event spaces, including a 6,000 SF lobby and flexible event space, 19,000 SF of permanent exhibition space, an education center, and a 200-seat multi-functional space.
