As part of federal emergency planning in the National Capitol Region, the hospital is also tasked with maintaining unique capabilities to support continuity of government in the event of crisis.

[2] The $1.03 billion, 1.3 million-square-foot facility opened in August 2011, replacing Fort Belvoir's existing medical facility, DeWitt Army Community Hospital, and integrating nearly half of the workforce of the former Walter Reed Army Medical Center in Washington, D.C., in accordance with 2005 Base Realignment and Closure Act.

The modern, 120-bed facility was designed by HDR, Inc. and is LEED Gold certified,[4] incorporating sustainable and natural elements and themes.

The facility incorporates a seven-story main structure, flanked on each side by two outpatient clinic areas providing both primary and specialty care.

In total, it consists of five total buildings, 3500 parking spaces, 44 clinics, expanded pharmacy services, 430 exam rooms, 10 operating rooms, two DaVinci surgical systems, two linear accelerator cancer/oncology systems, and one of the military's only dedicated substance abuse programs.

Inpatient services were tripled in volume over the old hospital, and the expanded outpatient specialty care center offers services as a more local and convenient alternative than Walter Reed National Military Medical Center, which is located over 30 miles away on congested highways.

The anticipated outpatient workload is expected to grow to more than 600,000 visits per year in primary, specialty and ancillary clinics.
