From secret wartime germ labs to modern cancer research, the evolution of Fort Detrick.

In short: Once a quiet airfield, this Maryland installation became the epicenter of American biological warfare research during the 1940s. Today, it serves as a hub for biomedical defense and cancer studies, though its history remains shadowed by environmental contamination, controversial human testing, and persistent global conspiracy theories regarding its true purpose.

Established in 1943 as Camp Detrick, the facility was chosen for its strategic balance between isolation and proximity to Washington, D.C. Under the oversight of the Chemical Warfare Service, it operated under extreme secrecy, mirroring the Manhattan Project. By 1945, the site employed over 1,700 personnel and had produced 5,000 anthrax-laden bombs. Following the war, the U.S. government integrated foreign scientists into its programs, while researchers studied pathogens like smallpox and Ebola. The base also conducted Operation Whitecoat, a series of experiments involving human subjects, including Seventh-day Adventist conscientious objectors.

The facility's mission shifted significantly in 1969 when President Richard Nixon outlawed offensive biological research. While the site transitioned to defensive work—focusing on diagnostics and medical countermeasures—it has faced ongoing scrutiny. In 2009, the Environmental Protection Agency designated a portion of the base, known as Area B, a Superfund site due to historical disposal of chemical and radiological waste. Groundwater contamination, including volatile organic compounds like trichloroethylene, remains a point of contention, though a 2012 National Research Council report concluded that historical health impacts are now impossible to definitively measure.

Fort Detrick remains a lightning rod for misinformation. In the 1980s, Soviet-linked disinformation claimed the government created HIV there, and more recently, officials in China alleged the facility was the source of SARS-CoV-2. These claims lack evidence. Despite these controversies, the campus is a major economic engine for Frederick County, hosting the National Cancer Institute and various interagency biodefense organizations. It continues to function as a critical, albeit complex, center for high-containment biological research and medical intelligence.
