Nike Missile Barksdale Defense Area
Two Nike Hercules sites, BD-10 at Bellevue and BD-50 northeast of Stonewall, were installed to provide protection to Shreveport and Barksdale AFB, which hosted Strategic Air Command bombers. U.S. Army Air Defense Command operated the sites with Regular Army units from 1960 until 1966. Battalion Headquarters was located at the Louisiana Army Ammunition Plant located north of Doyline.
