Aberdeen Proving Ground (APG) is the U.S. Army’s oldest active proving ground. It was established on the shores of Chesapeake Bay in Maryland’s Harford County in 1917 to provide the nation site where Army materiel could be masted and tested.  At the same time, the Edgewood Arsenal was established nearby to provide a site for the development, production, and testing of chemical warfare materiel.  The two installations were officially joined as Aberdeen Proving Ground in 1971.
