This book provides readers with an in-depth understanding of the professional development of two notable and highly accomplished naval officers and their contributions to the development of the Aegis Weapons System. The main argument is that there was no single career path or set of formal qualifications for achieving excellence in the naval profession as characterized by selection for Flag rank. One of the major points is the revelation that a combination of essential personal traits and qualities and important operational and technical experiences fundamental to the nature of naval warfare are critical to developing highly competent and confident officers. Such officers are needed to lead major acquisition programs capable of delivering innovative weapons systems for a twenty-first century Navy facing new age threats.
