Foley Co. 15% In the short span of 15 months, the contractor was able to meet deadlines essentially on schedule; building silos which were disposed over an area around the central support base. Operating under a schedule calling for combat-speed conditions, workmen built the twelve 174-feet deep silos and their supporting equipment in record time, with a minimum of delay. Labor-management relations throughout the entire phase of the construction program were excellent, and the critical work was not delayed by any strikes. Installation and check-out of missiles, sub-components and ground support equipment was continued by the Air Force with the integrating contractor. Upon completion of this phase, the site was turned over to the Strategic Air Command. ATLAS is this country's first operational Intercontinental Ballistic Missile. It was developed and produced by a military-contractor team. The Ballistic Systems Division, of the Air Force Systems Command, was under the command of Major General T. P. Gerrity, who was executive program manager. Astronautics Division of General Dynamics Corporation, was the airframe, assembly and test contractor. Rocketdyne Division, of North American Aviation, built the liquid-propelled engines. Early Atlas models had radio-inertial guidance, produced by General Electric Company and Burroughs Corporation, while the later "E" and "F" models have all- inertial guidance, made by American Bosch Arma Corporation. General Electric Missile and Space Vehicle Department was responsible for the re-entry vehicle. Space technology laboratories exercised systems engineering and technical direction. Schilling was only one of six ATLAS "F" sites, others being at Lincoln, Nebraska; Altus, Oklahoma; Roswell, New Mexico; Abilene, Texas, and Plattsburgh, New York. (Each of these sites to have between 9 and 12 Atlas "F" missiles ready to fire).
