Over the years, the proving ground underwent various name changes and periods of deactivation and reactivation.  In 1943, the Army established biological warfare and testing facilities at Dugway.  The size of the installation was increased in 1945 when part of the Wendover Bombing Range was transferred to the proving ground. After the war, the proving ground combined with the Desert Chemical Depot to form a single command called the Dugway Desert Command, later renamed the Western Chemical Center. The installation was then placed on a standby status.     In 1950, the center resumed active status and acquired an additional 279,000 acres of land for exclusive use. Work continued through the 1950s with new responsibilities added as defense weaponry evolved. In 1954, Dugway Proving Ground was confirmed as a permanent installation.  The Fort Douglas-based Desert Test Center and Dugway Proving Ground combined in 1968 and became known as the Desert Test Center.  This alliance lasted until 1973 when  the present Dugway Proving Ground became part of the U.S. Army Test & Evaluation Command, TECOM, headquartered at Aberdeen Proving Ground, Md.  In 1999 TECOM became the Developmental Test Command  aligned under the Army Test & Evaluation Command in Alexandria, Va.      

    Dugway Proving Ground now covers 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.
