Traditional thinking regarding the data transfer vehicle needed to interconnect elements of a distributed processing combat system generally envisions one or more data busses. This paper presents the somewhat unorthodox viewpoint that a distributed switching network is a better transition vehicle for moving from today's federated architectures to the distributed-processing architectures of the future. The structure and operation of a distributed switching network concept, called Standard Information Transfer Architecture for Combat systems (SITACS), is briefly described. Simulation results are presented which show throughput and timing values considerably better than that achievable by data bus systems.

The Shipboard Data Multiplex system (SDMS) is a general purpose information transfer system directed toward fulfilling the internal data Intercommunication requirements of a variety of naval combatant ships and submarines in the 1980–1990 time frame. The need for a modern data transfer system of the size and capability of SDMS has been increase in unison with the sophistication of shipboard electronic equipment and the associated magnitude of equipment-to-equipment signal traffic. Instead of the miles of unique cabling that must be specifically designed for each ship, SDMS will meet information transfer needs with general-purpose multiplex cable that will be Installed according to a standard plan that does not vary with changes to the ship's electronics suite. Perhaps the greatest impact of SDMS will be the decoupling of ship subsystems from each other and from the ship. Standard multiplex interfaces will avoid the cost and delay of modifying subsystems to make them compatible. The ability to wire a new ship according to a standard multiplex cable plan, long before the ship subsystems are fully defined, frees both the ship and the subsystems to develop at their own pace, will allow compression of the development schedules and will provide ships with more advanced subsystems. This paper describes the SDMS system currently being developed by the U.S. Navy.

ECKHART, MUSN (RET.)The Authoris currently Chief Scientist in the Autonetics Marine Systems Division
Rockwell International concentrating in Digital Simulation Applications in System Engineering. A graduate of the U. S. Naval Academy in 1945 he served in various surface assignments until 1950. Subsequent thereto after being designated an Engineering Duty Officer (ED) he had Type Commander Staff Laboratory ESO and Naval Shipyard assignments until 1962 when he became the Miltary Chairman Electrical Science at the U. S. Naval Academy. In 1965 he became the Head Electrical/Electronics Design Branch Bureau of Ships remaining in this assignment until 1967 when he assumed the responsibilities of Director Ship Concept Design Division Naval Ship Engineering Center. Upon retiring from the U. S. Naval Service in 1970 he joined Rockewell International and the following year became the Manager of the Integration Programs Group involved in Model—Based Systems Analysis EM Effectiveness Submarine Control and Ship Data Miltiplexing. His education includes a BS degree from the U. S. Naval Academy a BS degree in Electrical Engineering received from Massachusetts Institute of Technology in 1949and a MS degree in Electrical Engineering received from The George Washington University in 1967. A former ASNE Council Member
he has been active in ASNE at both the National and Local Section levels since 1967.

The general systems engineering state—of—the—art has not been equal to the functional diversity of modern multimission warships, nor to the more complex system relationships that are characteristically involved in their design. Resultant dependence upon qualitative assessments of higher level relationships in warship definition and design has been and is a critical impediment to the Navy's corporate purposes, both in prosecuting its vital rebuilding campaign and in dealing with the technological pace of naval warfare. A design methodology development, first reported on ASNE Day 74, has provided the basis for removing this impediment. The threshold criterion of systemengineering, quantification, and correlation of total system design objectives, can be satisfied for warship definition and design. Further, the basic elements of an exploitive systemengineering practice have been developed sufficiently to confirm their validity. This work is interpreted in terms of the systemengineering structure that can be expected to emerge; first, because it can be done, and second, because its payoffs are so urgently needed by the Navy.
This paper describes an exploratory design study for a modern general purpose combatant of destroyer size. The study was conducted in two principal segments by separate but interacting groups under the direction of th...
