Recent naval operations by the world's major navies show a clear revival of interest in piracy and piracy suppression. The present work of collaborative scholarship, completed as a project in the Maritime History Department at the U.S. Naval War College, demonstrates that historical insights from a selection of piracy case studies over the past two centuries have potential relevance to current and future thinking about antipiracy operations. This monograph is intended as a contribution to both scholarship and professional naval thinking; it is an academic and comparative examination of twelve selected case studies from maritime history used to illuminate a range of concepts and uses of piracy suppression. The twelve case studies provide the basis for the conclusions, an approach that provides a more thorough understanding of the uses and limitations of naval antipiracy operations in the context of new maritime technologies and within a wider range of modern national policy goals than might otherwise be achievable. Above all, this collection provides a sound basis for comparative analysis of varying historical experiences that can stimulate new and original thinking about a basic but often overlooked naval duty. The Newport Papers are extended research projects that the Director, the Dean of Naval Warfare Studies, and the President of the Naval War College consider of particular interest to policy makers, scholars, and analysts.
