S . Army until 1967 . Co - location with APG provided convenient access to the equipment being delivered to APG for testing after World War I . In 1965 local citizens formed the tax - free Ordnance Museum Foundation , Inc . to establish and operate a museum of these military artifacts . The Foundation is not affiliated with the U . S . Army , nor the Department of Defense . The Foundation began operation of the Museum in the early 1970s , upon opening in Building 2601 on the Aberdeen Proving Ground ( until its closing in September 2010 ) and operates the Ordnance Museum until this day .
