The discipline of weight engineering is traced through the history of man's development of water transportation. The awareness by early shipwrights of weight problems is presented by citing significant advances in the state of the art of shipbuilding. As counterpoint, the evolution of weight engineering is discussed from its beginnings as a subconscious consideration in early history through development of weight reporting as an engineering tool and ending as a relatively rigorous discipline involving the control of weight through the ability to make accurate and long range predictions of complex ships. Weight control is also identified with the role of the project manager of today by citing how it can be used as a management tool. The paper concludes that weight engineers are a dynamic part of the total engineering and management force collected in the shipbuilding effort. As such, they will be required to find new and better ways to maintain an effective program as traditional concepts of ship design and construction yield to new methods.

SHERRILL, WMGREEN, TCTRAVERS, DNWilliam M. Sherrill is Manager
Intercept and Direction Finding Research in the Department of Applied Electromagnetics at Southwest Research Institute San Antonio. He received his M.S. in Physics from Rice University in 1959 and his bachelor degrees in Physics and Mathematics from the University of Texas in 1957. Since joining the staff of Southwest Research Institute in 1959 he has been engaged in Naval shipboard radio direction finding research concentrating on advanced techniques of direction finding using multichannel receivers fixed antennas and the application of digital logic and computation in DF system control. He is a member of the Institute of Electrical and Electronics Engineers IEEE Professional Group on Antennas and Propagation American Astronomical Society and the Scientific Research Society of America. Terry C. Green is a Senior Research Engineer in the Department of Applied Electromagnetics at Southwest Research Institute
San Antonio. He took the B.S. in Electrical Engineering from the University of Texas in 1958 and served as a commissioned officer in the U. S. Air Force from 1958 to 1962. His duties as a USAF officer included experience in military search and tracking radar and electrical support equipment design for high performance fighter aircraft. In 1962 he joined the staff of Southwest Research Institute and has been engaged in high frequency and very high frequency radio direction finding techniques for surface ship and submarine application. He is a member of the IEEE Professional Group on Antennas and Propagation and Sigma Pi Sigma. Douglas N. Travers is Director of the Department of Applied Electromagnetics at Southwest Research Institute
San Antonio. He obtained his B.E. in Electrical Engineering from Johns Hopkins University in 1951 and joined the staff of Southwest Research Institute in 1951.

This report summarizes the practical requirements for siting radio direction finders operating in the 3 to 30 mc range and is intended primarily for the use of personnel responsible for site selection and DF antenna installation on Naval ships. The effects of reradiation from the ship's superstructure on direction finder performance are described. By the use of specific examples of shipboard installations, the merits of various siting compromises are discussed.

FERRIS, LAWRENCE W.FREY, RICHARD A.MILLS, JAMES L.Laurence W. Ferris graduated from the University of California in 1916. After working at shipyards on the West Coast
came to the Bureau of Construction and Repair in 1925 and has contributed to the design of a wide variety of ships. For several years was head of a section dealing with structural design of turrets ammunition handling and allied subjects. More recently has been a Project Coordinator in the Bureau of Ships. Retired in June 1962. Author of the following papers: “The Effect of an Added Weight on Longitudinal Strength” SNA & ME 1940 “The Proportions and Form of Icebreakers”
SNA & ME 1959 “Developable Surfaces”
ASNE 1961. Richard A. Frey entered the Bureau of Ships upon graduation from Manhattan College
N. Y. in 1951. From 1951 through early 1957 he was on the Destroyer Type Desk and was primarily involved in the hull electronic and ordnance aspects of all destroyer type ships. From 1957 through 1962 Mr. Frey headed up the Surface-to-Surface Missile ASW Conventional Armament and Auxiliary Section of the Bureau of Ships Weapons Branch. His duties entailed all aspects relative to the installation of such weapon systems as REGULUS ASROC SUBROC torpedoes conventional guns and similar ordnance in various surface and sub-surface craft. Mr. Frey has been recently detailed to the Bureau's new SEAHAWK Program Management Office. James L. Mills
Jr. holds a bachelor's degree in Naval Architecture and Marine Engineering from the Webb Institute of Naval Architecture. Following his graduation in 1944 he was ordered to the USNR Midshipman's School at Cornell the Navy Fire Fighting and Damage Control School in Philadelphia and then to duty in the Construction and Repair Department aboard the USS PENNSYLVANIA. He subsequently served as the Assistant First Lieutenant and Damage Control Officer in that ship. After release from active duty Mr. Mills did naval architectural work at the David Taylor Model Basin the Naval Engineering Division of the U. S. Coast Guard and Bethlehem Steel's Staten Island
