The U.S. Army Biological Warfare Laboratories (USBWL) were a suite of research laboratories and pilot plant centers operating at Camp (later Fort) Detrick, Maryland, USA beginning in 1943 under the control of the U.S. Army Chemical Corps Research and Development Command. The USBWL undertook pioneering research and development into biocontainment, decontamination, gaseous sterilization, and agent production and purification for the U.S. offensive biological warfare program. The Laboratories and their projects were discontinued in 1969.
