Shumaker Naval Ammunition Depot

The Shumaker Naval Ammunition Depot was a munitions manufacturing facility of the United States Navy located in Calhoun and Ouachita counties in southern Arkansas. It operated from 1945 until 1957, producing Sidewinder missiles and other weapons. The property was sold off in 1961. Part of the original site now houses Southern Arkansas University Tech. Two of its surviving buildings, the 500-Man Barracks and the Administration Building, were listed on the National Register of Historic Places in 2018.

At the time of construction, the depot was planned to be a 110 square mile site serving as the "principal rocket loading, assembly, and storage plant" for the United States, with a permanent complement of 5000 personnel.
