Underwater vehicles and underwater moorings are increasing in tactical importance. As such, it is critical to have a robust and secure communication system connecting underwater vehicles on a long seaborne mission and a ground station. As a matter of fact, the deployment of efficient communication links with underwater vehicles is one of the greatest technological challenges presently confronted by the world's naval forces.To circumvent most of the limitations involved in the use of RF or acoustic channels for perfectly secure communications with underwater vehicles, it is worth considering the feasibility of an optical channel to facilitate a two-way satellite communication link secured via perfectly secure ciphers enabled by a quantum key distribution protocol.This book offers a concise review of underwater communications systems. Our approach is pedagogical, making a strong emphasis on the physics behind the attenuating properties of the oceanic environment and the propagation of electromagnetic signals in the ELF, VLF, and optical bands. We assume the reader is familiar with the basic principles of classical electrodynamics and optics.The system design, components, and noise analysis of an underwater optical communications device are discussed in detail. Furthermore, we offer simulations of the performance of the communication system for different types of ocean waters. Our final conclusion is that it appears to be feasible to design and build underwater communications using optical classical and quantum channels secured with quantum key distribution protocols.

Whilst maritime studies tend to reflect the dominance of large navies, history shows how relatively small naval forces can have a disproportionately large impact on global events. From Confederate commerce raiders in the nineteenth century, to Somali pirates today, even the most minor of maritime forces can become a key player on a global stage. Examining a broad range of examples, this volume addresses the roles and activities of small navies in the past and the present at the national, regional and international level. In particular, it focusses on the different ways in which such forces have identified and addressed national and international security challenges and the way in which they interact with other navies and security agencies. In addition the collection also investigates the relationship of such navies with non-governmental organisations, institutions and bodies in pursuit of broader maritime goals, be they political, financial or environmental. Adopting an interdisciplinary approach drawing on the best new research from the fields of international relations, security studies, strategic studies and maritime history, the book examines the diversity of experience amongst different smaller navies and also establishes areas of similarity. Divided into two sections, part one begins with a number of chapters that are theoretical in nature, whilst part two provides case studies that offer a more regional focus, including analysis of the challenges facing contemporary navies and historical case studies designed to reveal the experience of small navies over time. By adopting an approach that combines historical considerations with analysis of current events, the collection offers a unique perspective on the role that small navies have played in wider nautical affairs and their continued impact upon global maritime strategies.

Which military missions for unmanned undersea vehicles (UUVs) appear most promising to pursue in terms of military need, operational and technical risks, alternatives, and cost? To answer this question, the authors assess risks associated with using UUVsfor advocated missions, identify non-UUV alternatives that may be more appropriate for such missions, and analyze potential costs associated with UUV development and use. They conclude that seven missions: mine countermeasures, deployment of leave-behindsurveillance sensors or sensor arrays, near-land and harbor monitoring, oceanography, monitoring undersea infrastructure, anti-submarine warfare tracking, and inspection/identification - appear most promising. Among other recommendations, the authors suggest that the U.S. Navy consolidate its unmanned system master plans and establish relevant priorities in coordination with the Office of the Secretary of Defense. Increased emphasis on the use of surface platforms rather than submarines as host platformsis recommended.

China's military modernization is focused on building modern ground, naval, air, and missile forces capable of fighting and winning local wars under informationized conditions. The principal planning scenario has been a military campaign against Taiwan, which would require the People's Liberation Army (PLA) to deter or defeat U.S. intervention. The PLA has sought to acquire asymmetric "assassin's mace" technologies and systems to overcome a superior adversary and couple them to the command, control, communications, computers, intelligence, surveillance, and reconnaissance (C4ISR) systems necessary for swift and precise execution of short-duration, high-intensity wars. A key element of the PLA's investment in antiaccess/area-denial (A2/AD) capabilities is the development and deployment of large numbers of highly accurate antiship cruise missiles (ASCMs) and land-attack cruise missiles (LACMs) on a range of ground, air, and naval platforms. China's growing arsenal of cruise missiles and the delivery platforms and C4ISR systems necessary to employ them pose new defense and nonproliferation challenges for the United States and its regional partners. This study surveys People's Republic of China (PRC) ASCM and LACM programs and their implications for broader PLA capabilities, especially in a Taiwan scenario.

Krone der Schöpfung? Vor 100 000 Jahren war der Homo sapiens noch ein unbedeutendes Tier, das unauffällig in einem abgelegenen Winkel des afrikanischen Kontinents lebte. Unsere Vorfahren teilten sich den Planeten mit mindestens fünf weiteren menschlichen Spezies, und die Rolle, die sie im Ökosystem spielten, war nicht größer als die von Gorillas, Libellen oder Quallen. Vor 70 000 Jahren dann vollzog sich ein mysteriöser und rascher Wandel mit dem Homo sapiens, und es war vor allem die Beschaffenheit seines Gehirns, die ihn zum Herren des Planeten und zum Schrecken des Ökosystems werden ließ. Bis heute hat sich diese Vorherrschaft stetig zugespitzt: Der Mensch hat die Fähigkeit zu schöpferischem und zu zerstörerischem Handeln wie kein anderes Lebewesen. Anschaulich, unterhaltsam und stellenweise hochkomisch zeichnet Yuval Harari die Geschichte des Menschen nach und zeigt alle großen, aber auch alle ambivalenten Momente unserer Menschwerdung.

Wichtigstes Ziel der Publikation ist die Präsentation empirischer Ergebnisse bezüglich der politischen Orientierungen sowie der Entwicklung dieser Orientierungen in der ersten Klasse der Grundschule. Dabei wird zunächst nachgewiesen, wie Kinder Politik verstehen und auf welche Weise dieses Verständnis für die empirische Politikforschung zugänglich gemacht werden kann. Hauptthema des Bandes liegt auf der Beschreibung politischer Orientierungen junger Kinder auf der Basis der beiden Wellen der Kinderbefragung des Forschungsprojekts 'Demokratie Leben Lernen' (etwa 800 Kinder). Die Analysen sind auf drei Hauptbereiche (Themen, Wissen, Werte) fokussiert. Die hierbei aufgedeckten Unterschiede in Niveau und Persistenz der politischen Orientierungen werden auch auf ihren Zusammenhang mit einigen wichtigen Einflussfaktoren wie Geschlecht, Alter, Nationalität usw. untersucht.

Kampf um Trinkwasser, Massengewalt, ethnische „Säuberungen, Bürgerkriege und endlose Flüchtlingsströme bestimmen schon jetzt die Gegenwart. Die heutigen Konflikte drehen sich nicht mehr um Ideologie und Systemkonkurrenz, sondern um Klassen-, Glaubens- und vor allem Ressourcenfragen. Der Autor plädiert für ein neues Denken und zeigt, was jetzt getan werden müsste, um Menschheitskatastrophen abzuwenden.
