The Detroit Arsenal Tank Plant (DATP) was the first manufacturing plant ever built for the mass production of tanks in the United States. Established in 1940 under Chrysler, this plant was owned by the U.S. government until 1996. It was designed by architect Albert Kahn. The building was designed originally as a "dual production facility, so that it could make armaments and be turned into peaceful production at war's end. Notwithstanding its name, the site was located in Warren, Michigan, Detroit's largest suburb. The base's fire station has a Thunderbolt siren on top. It is a model 1000.
