Aberdeen Proving Ground (APG) 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 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. The two areas of APG—Aberdeen Area (AA / APG North) and the Edgewood Area (EA / APG South) are separated by the Bush River and are approximately 15 road miles apart. Workers at APG are responsible for numerous technical achievements in military intelligence, medical research, engineering and computer technology. With more than 21,000 civilian, military and contractor employees, APG is Harford County’s largest employer and one of the largest employers in the state of Maryland. APG contributes more than $400 million in payroll and $500 million in contracts annually.
