Established in the fall of 1917, Aberdeen Proving Ground saw to the testing of ordnance materials in an industrialized area. In part, APG was built to succeed the Sandy Hook Proving Ground which had become insufficient for testing the larger weapons that the military was developing.

World Wars

During World War I, the U.S. Government built plants to produce toxic gas at APG which became known as the Edgewood Arsenal. Edgewood produced chemicals like mustard gas and, in a separate facility, artillery shells to fill with the toxins. In total, 10,817 tons of gas were produced at Edgewood before the WWI armistice was reached. APG also includes the Churchville Test Area, a track on which M1 Abrams Tanks, Bradley Fighting Vehicles, Humvee's and other military vehicles are tested.

Post WWI, APG slowed down its operations until WWII began and government funding expanded APG's facilities. At the end of WWII, APG once again saw a decrease in usage of its facilities. Aberdeen Proving Ground is Harford County's largest employer and one of Maryland's largest employers overall.
