In reactivating the battleship New Jersey , the Navy faced three major problems. The baseline data on the ship was not readily available or reliable, a new generation cruise missile armament was proposed, and the ship delivery schedule was very tight. After doing a feasibility study, system design engineers were taken onboard the mothballed ship to resolve the design problems. Being on the ship allowed an intensive effort and immediate reference to the actual ship configuration. The tools used to control this effort were a ship check plan, a ship check form and the master arrangement drawing. Simultaneously with the design effort, a repair scoping effort was conducted. The design evolution and solutions to the major problems are described. The results of the New Jersey effort are shown with sample documentation, the ship characteristics and the downstream design effort. The Iowa was the next ship to be modernized. The top level requirements were the same as New Jersey's but new problems were encountered. More options were investigated which diverted attention from the basic effort. A fundamental difference was the Iowa had not had a 1968 reactivation as the New Jersey had, so items that were repair and reactivation on the New Jersey in 1968 had to be part of the Iowa modernization. A major influence on the Iowa design process was that a complete set of specifications for a private yard bid had to be developed. The next effort was to install the same New Jersey modernization payload on a Des Moines class heavy cruiser. Heavy cruisers are large ships but significantly smaller than battleships and much closer to their naval architectural limits of weight and center of gravity. They have much less topside area than the battleships, and the new payload was very topside space consuming. The cruisers are also much more restricted in internal volume. Two feasibility studies were conducted. One resolved volume problems but approached the weight and center of gravity limits.

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.

He received his Bachelor of Science degree in Mechanical Engineering from Stanford University in 1960 and was then commissioned in the U.S. Navy serving as Engineering Officer in the USS Braine (DD-630). Upon completion of his active duty assignments he entered industry as a Development Engineer and became involved with marine application of gas turbine and fluid power systems. In 1966 he assumed full responsibility for the installation design and equipment acceptance tests of the gas turbine generator/waste-heat boiler system for the DDH-280 Class Destroyer including all associated controls ducting and silencing equipment. In 1970 he became Manager of the DD-963 Auxiliary Power “Trade-Off” Study which resulted in significant modification to the electric steam and compressed air systems.
