NNSA is run from headquarters buildings spread over three sites: the Forrestal Building in Washington, DC, home of the Department of Energy; the department's Germantown Building in Germantown, Maryland; and the Albuquerque Complex at Kirtland Air Force Base in Albuquerque, New Mexico.

In addition, NNSA oversees its contractor-operated national laboratories, production plants, and test and experiment facilities through field offices that are mostly co-located with the facilities they supervise. The field offices are responsible for ensuring compliance with federal contracts to manage and operate the national security assets located in California, Idaho, Missouri, Nevada, New Mexico, New York, Pennsylvania, South Carolina, Tennessee, and Texas.

To provide oversight for the diverse facility missions, each field office employs subject matter experts in specialties such as emergency management, physical security, cybersecurity, safety, national security, nuclear facility operations, environmental protection and stewardship, radioactive waste management, quality assurance, business and contract administration, public affairs, and project management.

Additionally, field offices engage with stakeholders, including leaders and members of surrounding communities, cities, local and tribal governments, and business and non-governmental organizations.
