This textbook is intended to serve as an introduction to the underlying science and engineering of weapons used in the naval service. The philosophy used in the material selected for this text is that individual weapons come and go, but the principles of their operation largely remain the same. Some subjects are covered in greater detail than needed for an introductory course to allow this text to serve as a basic reference to take into professional life.
The text was written to be inclusive of all college majors; as such a conscious effort was made when possible to apply algebra, geometry, trigonometry, and avoid calculus. Therefore, many of the equations derived are 1st order, and provide approximations that are sufficient to illustrate the relative performance parameters of variables used in weapon system design. These same theories and principles can then be applied to actual sensors and weapons using operational parameters and specifications determined from technical manuals and warfare publications.
Material has been drawn from pervious texts of the same title that have explained the principles for the last 40 years. Much of the work can be traced to the work completed by the Bureau of Naval Weapons in the 1960’s. It was updated and expanded in the 1980’s version and incorporated in this text. In some cases, principles of systems that the U.S. Navy no longer uses are described in a belief that sometimes it is good to know where you have been to know where you are going. In addition, many countries and organizations still employ some of these lower technology systems. Therefore, it is necessary to understand their basic capabilities. With advent of new technologies and methods, this text will require periodic updating.
