Rugged Communications Link Atlas Sites
Atlas ICBM launch sites, dispersed over an 8,000-sq.-mi. area at Fairchild AFB, Wash., have been linked to an underground command control center by means of a toughened microwave communications system designed to withstand bomb-blast overpressures up to 25 psi. (The term “hardened” usually is applied to facilities capable of withstanding overpressures of 100 psi. or more.)
