The major portion of the cable used in an SD system is of an armorless coaxial design, with a strength member within the inner conductor structure. It is fabricated in continuous 20-nautical mile repeater sections and is stored, when finished, in individual pans. Every section is therefore available in any sequence to facilitate the most nearly ideal ship loading schedule. This paper summarizes the process experience gained during the cable design and development program, details the processes involved in the purchase of cable raw material, discusses the manufacturing operation, and includes a measure of cable reproducibility for the Baltimore plant of the Western Electric Company.
