The structural design of a ship's section is a complicated, repetitive and time consuming task. With the advent of new technology, high speed computers have enabled the ship designer to accomplish in a matter of seconds what would formerly take days to accomplish by hand. The Structural Synthesis Design program (SSDP) is a N avy developed computer-aided design tool which is used to design (or to analyze) the longitudinal scantlings for a variety of ship cross sections, consisting of any practical combinations of decks, platforms, bulkheads and materials, i.e., various steel and aluminum alloys. The final hull section design will have the lowest practical weight for the chosen geometric configuration, structural arrangements, and imposed loadings. The scantling developed by the program will satisfy all U.S. N avy ship structural design criteria. An explanation of the objective and design elements of N avy ship structures is included. The rationale behind the SSDP design philosophy is developed along with the significant program capabilities. In an attempt to highlight the influence of automated design procedures on the current naval ship design process, the effect of the SSDP on the DDG 51 destroyer structural development is addressed.

This paper descirbes how ship weights are estimated. Detail is presented concerning relationships between existing weight data and the characteristics of a new design as it develops from completion of feasibility design through contract design. Margin requirements are also discussed. The weight estimating ratios and factors presented, while not directly associated with a specific ship type, cover the weight classification groups one would use in the design of a surface combatant. The purpose of this paper is to present the fundamentals of weight estimating to the ship design community. With this knowledge, ship design engineers and managers should be able to personally identify with the important parts they all play in creation of a credible weight estimate.

BENNETT, RAWSONUSN Chief of Naval ResearchTHE AUTHOR was born on June 16
1905. in Chicago Illinois. He was appointed to the U. S. Naval Academy Annapolis. Maryland from California in 1923. Graduated and commissioned Ensign on June 2 1921 he subsequently advanced to the rank of Captain to date from March 20 1945. In December 1955 he was appointed Rear Admiral to date from January 3 1956. Following graduation in 1927 he joined the USS California flagship of the Battle Fleet. Later in 1928. he was assigned communication duty on the staff of Commander Battle Fleet serving as such until August 1930. In November of that year he reported on board the USS Isabel for duty on Asiatic Station and in October 1932 was transferred to the USS Rochester. He completed his Asiatic tour of duty in the USS Houston in 1933. Detached from this vessel he returned to the United States and joined the USS Idaho. After 7 years of sea duty he returned to Annapolis Maryland for postgraduate instruction in radio (electronic) engineering. He completed the course in May 1936 and was assigned to the University of California Berkeley for additional postgraduate work receiving the Master of Science degree in Electrical Engineering after which he reported aboard the USS Concord. Continuing sea duty he joined the staff of Commander Destroyer Division Nineteen (later redesignated Destroyer Fifty) in April 1938 and served as Radio and Sound Officer until June 1941. Starting in July 1939 he set up the technical program of the first fleet Sound School at San Diego California. In July 1941 he reported to the Bureau of Ships Navy Department Washington D.C. There he served first as Head of the Underwater Sound Design Section of the Radio Division and later Head of Electronics Design Division from 1943 to 1946. He was awarded the Legion of Merit “for exceptionally meritorious conduct” during this tour of duty. Upon leaving the Bureau of Ships in August 1946 he reported as Director of the U. S. Navy Electronics Laboratory Point Loma
