Aberdeen Proving Ground (APG) was established by order of President Woodrow Wilson on October 20, 1917, 6 months after the United States entered World War I and officially opened in December 1917. The Army had taken over 69,000 acres of land and water to provide an area for design and testing of ordnance. Sandy Hook, NJ and the Army’s proof and acceptance testing ground for ammunition and cannon since 1874 was being closed and the Chesapeake Bay site was selected as the best suited to carry the mission of testing field artillery.
From this beginning, APG has grown and evolved into one of the most diversified military installations in the United States. On land acquired 16 miles from Aberdeen, the Edgewood Area of APG (formerly known as Edgewood Arsenal) was also developed in 1917 as a chemical weapons, research, development and testing facility. The July 1971 merger of Edgewood Arsenal and Aberdeen Proving Ground created a unique combination of activities and missions.
Today, APG is recognized around the world as a leader in the research, development, testing and evaluation of materiel.
The growth from BRAC 2005 represents APG's largest expansion since World War II. With this BRAC came the electronics and communications that realign and complement support for the war fighter. Aberdeen Proving Ground continues to reinvent itself to meet the demands of the day. Drawing on its long history in computing, organizations at APG are at the leading edge of development of new technologies to address one of the major threats to national security today - cybersecurity.
