The American political process has long been marked by the active role of community and grass-roots organizations. In spite of continued concentration of power at formal levels of government, local and community institutions remain 1) the focus of citizen Involvement 2) the direct providers of services and the advocates of local interests, and 3) frequently the only representatives of lowincome and minority populations, and women. Their record must be preserved and their role reinvigorated.

USN: was graduated from the U.S. Naval Academy in 1956 and subsequently served as a gunnery division officer in an attack aircraft carrier and as gunnery officer operations officer and chief engineer in two diesel submarines. He attended MIT from 1962–1965 earning a master of science in mechanical engineering and a naval engineers degree. Early assignments as an engineering duty officer included SRF Yokosuka CINCPACFLT staff and SupShip Pascagoula. From 1976 to 1987 he served in a variety of senior ship design assignments: CVV ship design manager director NAVSEC Hull and Ship Design Divisions director NavSea Ship Design Management and Integration Office commander David Taylor Naval Ship R&D Center and director NavSea Ship Design Group. Recently retired but recalled to active duty he is the professor of naval construction and engineering at MIT. He has received seven personal decorations including two Legion of Merit awards. Robert G. Keane
Jr.:is currently the deputy director of the NavSea Ship Design Group. He has been employed by NavSea and its predecessor organizations for over twenty years.

Some fairly radical changes to the naval ship design process occurred during the 1970s. The decade of the 80s has also witnessed a steady stream of changes. One of the most significant was the establishment of the Ship Characteristics Improvement Board (SCIB) in the Office of the Chief of Naval Operations (OpNav), and the resulting influence on the dialog between the military requirements decision makers and the Navy's ship designers. Other changes have occurred for which the impacts are less clear. These include establishment of the chief engineer of the Navy (ChEng) position, creation of the Space and Naval Warfare Systems Command (SpaWar) and OpNav's “Revolution at Sea” initiative. This paper will describe and discuss these and other changes, and comment on the resultant impact. The authors will attempt to present a global view of the total pattern of changes and try to discern if we are on a path of revolution, or merely normal evolution.

Jr. USN (Ret.):is well known for his work in comparative naval architecture studies of U.S. and foreign warship design practices for which he received the American Society of Naval Engineer's Gold Medal for 1981 and the Legion of Merit in 1982. He received the ASNE “Jim-mie” Hamilton Award for 1983. He is currently a partner in Spectrum Associates Incorporated Arlington Virginia. Prior to his retirement in 1982 his naval career included sea duty aboard three destroyers and three aircraft carriers including command of a destroyer and engineer officer of an aircraft carrier. Kenneth Brower:is a partner in Spectrum Associates Incorporated
a naval engineering firm which he founded in 1978 which is currently engaged in the design of naval ships comparative naval architecture studies and the development of ship design synthesis computer programs. A graduate in naval architecture from the University of Michigan he has contributed to the design of numerous warships and merchant ships as well as several frigate designs for foreign military sales. Mr. Brower has been the author or coauthor of numerous technical studies and articles. He received the ASNE “Jimmie” Hamilton Award for 1983. Erbil Serter:is the director of Hydro Research Systems S.A.
Geneva Switzerland. He is a graduate in naval architecture from Sunderland College and the Imperial College of Science and Technology of London University in England where he earned a D. I. C. in aeronautics. Mr. Serter is a Fellow of the Royal Institution of Naval Architects and a member of the Royal Society of Aeronautics. His interest in deep-Vee hull forms began with his involvement in the early investigations of fast patrol boat design concepts. In the early 1970s he developed a 200-ton FPB design with a deep- Vee hull form called the SAR-33 fourteen of which have been built for Turkey. Since 1974 Mr. Serter has been developing deep-Vee hull form designs between 600- and 7000-tons.

A unique deep-Vee hull form has been developed and model tested in Europe for use in the design of corvette and frigate sized ships. The seakeeping performance of this new deep-Vee hull form, whose proportions are suitable for ship operations in a displacement mode at conventional speed-to-length ratios, exceeds the performance of ships with more conventional round-bilge hull forms. It promises to provide a 4,500-ton frigate with the speed, course selectivity, and combat system performance equivalent to that of larger destroyers when operating in the high latitudes of the North Atlantic, especially during the winter season. The authors describe and compare the seakeeping performance of two 4,500-ton frigates, one with a deep-Vee and the other with a round-bilge hull. They discuss the impact of differences in seakeeping performance on combat system availability. From the standpoint of incorporating a deep-Vee hull form into a ship design, certain features of a deep-Vee hull form affect ship proportions, calm water resistance, hull structure (particularly hull girder bending moments), stability, deck area, arrangements, propulsion plant configuration, light ship weights and centers of gravity, and acquisition and life cycle costs differently than a round-bilge hull form. Based on a comparative feasibility design study of two frigates of about 4,500-tons, one with a deep-Vee and the other with a round-bilge hull, the authors quantify the impact of these differences on a ship design.

The design of the new 108-ft yard patrol craft (YPs) for the U. S. Naval Academy is described from its beginnings as a senior midshipman design project, through its preliminary and contract design development at the U. S. Navy's small craft design team headquarters, Naval Sea Combat Systems Engineering Station, Norfolk, Virginia (NAVSEACOMBAT-SYSENGSTA-Norfolk). During preliminary and contract design the Naval Academy Hydromechanics Laboratory (NAHL) provided experimental data to support NAVSEA-COMBATSYSENGSTA-Norfolk's design analyses in powering, seakeeping, and maneuvering. Several tradeoff studies of interest to patrol craft designers are presented. Major events in the detail design and construction of the first boat are described from both the designer's and the shipbuilder's points of view. The launching, builder's and sea trials of the first boat are described.

The 5 January 1972 announcement by President Richard Nixon that the United States would develop during the 1970's a new space transportation system—the space shuttle—has had fundamental impacts on the character of U.S. space activities. In retrospect, it can be argued that the shuttle design chosen was destined to fail to meet many of the policy objectives established for the system; the shuttle's problems in serving as the primary launch vehicle for the United States and in providing routine and cost-effective space transportation are in large part a result of the ways in which compromises were made in the 1971-72 period in order to gain White House and congressional approval to proceed with the program. The decision to develop a space shuttle is an example of a poor quality national commitment to a major technological undertaking.
Prior to the energy crisis of 1973, the U.S. did not have an energy policy. The failure of the American political system to anticipate and respond to the changing facts of energy was an inevitable outcome of the way p...

Space advocates have increasingly promoted the commercial potential of space activities to justify public expenditures for space programs. Satellite communications will continue to be a viable space enterprise; however, transportation services for satellite launching have limited commercial prospects. The commercial viability of on-orbit services will be dependent upon the development of a large-scale space industry based on materials processing and space manufacturing. While space manufacturing may yield potentially high payoffs to the private sector, these will not be realized in the short term. A substantial amount of research into real space business opportunities must be conducted before sizable private investments are made in space manufacturing. In addition, space manufacturing will require the development of an extensive orbital infrastructure which will take years to complete. Space advocates should stress the scientific and exploration benefits of the space program rather than its remote economic payoffs.
