Aberdeen Proving Ground, the Army's oldest active proving ground, was established on October 20, 1917, six months after the United States entered World War I, to provide the military a facility where design and testing of ordnance materiel could be carried out in close proximity to the nation's industrial and shipping centers. The post officially opened on December 14, 1917, and the first gun was fired on January 2, 1918.

Aberdeen Proving Ground occupies more than 72,500 acres in Harford County, Maryland.  Its northernmost point is marked by the confluence of the Susquehanna River and the Chesapeake Bay. On the south it is bordered by the Gunpowder River.

The installation comprises two principal areas, separated by the Bush River. The northern area is known as the Aberdeen Area, and the southern sector, formerly Edgewood Arsenal (established in November, 1917 - as a chemical weapons research, development and testing facility), is the Edgewood Area. The two areas were administratively combined in 1971.  APG property not attached to the main installation includes the Churchville Test Site in Harford County and Carroll Island and Graces Quarters in Baltimore County.
