Picatinny Arsenal, State Route 15 near I-80, Dover, Morris County, NJ

Significance: Originally built as a depot for the storage of powder and other armaments, in the 20th century Picatinny Arsenal became a leading facility for the research and development and production of munitions. Following a catastrophic accident in July 1926, when a large portion of the site was destroyed by a lightening-ignited explosion, this Federal reservation was rebuilt. With the outbreak of World War II, Picatinny Arsenal became a major supplier of munition to Allied Forces and, more importantly, provided plans and personnel training required in the construction and operation of other munition facilities. During the Korean and Vietnam conflicts, Picatinny Arsenal remained active in both production engineering and research.
