Dugway Proving Ground

Dugway Proving Ground's primary mission is testing U.S. and Allied chemical and biological (CB) defense systems and performing nuclear, biological and chemical (NBC) survivability testing and training of defense materiel using CB agents and stimulants. With over 80 years of experience, the proving ground uses its state-of-the-art laboratories and chambers to conduct the testing and training under environmentally controlled conditions.

The attack on Pearl Harbor, in 1941, jarred the United States and its military forces. The nation suddenly realized a need for increased military capability in many areas, which included expanded knowledge in chemical and biological warfare. On March 1, 1942, Dugway Proving Ground was established, and testing was under way by that summer. Dugway was authorized to fill the need for testing weapons and defenses against chemical and biological weapons of mass destruction. Important projects during this early period included testing incendiary bombs, chemical weapons, and modified agents as spray disseminated from aircraft. Over the years, Dugway has expanded in size to 798,855 acres. In addition to chemical and biological defensive testing and environmental characterization and remediation technology testing, Dugway is the Defense Department's leader in testing battlefield smokes and obscurants. Also, within the last few years, Emergency Responders, i.e., Civil Support Teams (CST), are able to train at Dugway and become better prepared in case of terrorist attacks or chemical/biological incidents.
