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.

Maritime Power in the Black Sea provides the first comprehensive assessment and evaluation of the comparative maritime power of the six littoral states in the Black Sea - Turkey, Russia, Ukraine, Georgia, Romania and Bulgaria. This book examines the maritime capabilities and assets of each of the six littoral Black Sea states and also considers the implications of the distribution of maritime power on both regional and international security. As such it makes an important contribution to the debate about what constitutes maritime power in the twenty first century and provides a thematic comparative study of the ability of each of the littoral states of the Black Sea to project maritime power.

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.
