An alphabetically organized encyclopedia that provides both a history of military communications and an assessment of current methods and applications. Military Communications: From Ancient Times to the 21st Century is the first comprehensive reference work on the applications of communications technology to military tactics and strategy—a field that is just now coming into its own as a focus of historical study. Ranging from ancient times to the war in Iraq, it offers over 300 alphabetically organized entries covering many methods and modes of transmitting communication through the centuries, as well as key personalities, organizations, strategic applications, and more. Military Communications includes examples from armed forces around the world, with a focus on the United States, where many of the most dramatic advances in communications technology and techniques were realized. A number of entries focus on specific battles where communications superiority helped turn the tide, including Tsushima (1905), Tannenberg and the Marne (both 1914), Jutland (1916), and Midway (1942). The book also addresses a range of related topics such as codebreaking, propaganda, and the development of civilian telecommunications.
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.

In 1873 Scottish physicist James Clerk Maxwell first advanced the idea that there might be electromagnetic waves that were similar to light waves, a startling concept to the scientists of his day. About 13 years later, German physicist Heinrich Hertz demonstrated in his laboratory that electromagnetic radiation did indeed exist. But it was not until after Hertz's death that a young Italian named Guglielmo Marconi got the idea for a practical communications system based on Hertz's work. Marconi was surprised and disappointed that the Italian government was not interested in his newly discovered wireless communications system, and thus he took his equipment to England. From that point on, the wireless became identified with Britain. From these beginnings, wireless radio became the basis of a revolution that has resulted in the satellite communications of today. This history first looks at Marconi's invention and then explores its many applications, including marine radio, cellular telephones, police and military uses, television and radar. Radio collecting is also discussed, and brief biographies are provided for the major figures in the development and use of the wireless.
Only the author of The Hunt for Red October could capture the reality of life aboard a nuclear submarine. Only a writer of Mr. Clancy's magnitude could obtain security clearance for information, diagrams, and photographs never before available to the public. Now, every civilian can enter this top secret world...the weapons, the procedures, the people themselves...the startling facts behind the fiction that made Tom Clancy a #1 bestselling author.
This book provides a complete history of the US Fleet Ballistic Missile programme from its inception in the 1950s and the development of Polaris to the deployment of Trident II in 1990. Writing in an accessible yet scholarly manner, Graham Spinardi bases his historical documentation of FBM development on interviews with many of the key participants. His study confronts a central issue: is technology simply a tool used to achieve the goals of society, or is it an autonomous force in shaping that society? FBM accuracy evolved from the city-busting retaliatory capability of Polaris to the silo-busting 'first strike' potential of Trident. Is this a case of technology 'driving' the arms race, or simply the intended product of political decisions? The book provides a comprehensive survey of the literature looking at the role of technology in the arms race, and seeks to explain technological development using a 'sociology of technology' approach.
Now a 6-part mini-series called Why the Rest of Us Die airing on VICE TV! The shocking truth about the government’s secret plans to survive a catastrophic attack on US soil—even if the rest of us die—is “a frightening eye-opener” (Kirkus Reviews) that spans the dawn of the nuclear age to today, and "contains everything one could possibly want to know" (The Wall Street Journal). Every day in Washington, DC, the blue-and-gold first Helicopter Squadron, codenamed “MUSSEL,” flies over the Potomac River. As obvious as the Presidential motorcade, most people assume the squadron is a travel perk for VIPs. They’re only half right: while the helicopters do provide transport, the unit exists to evacuate high-ranking officials in the event of a terrorist or nuclear attack on the capital. In the event of an attack, select officials would be whisked by helicopters to a ring of secret bunkers around Washington, even as ordinary citizens were left to fend for themselves. “In exploring the incredible lengths (and depths) that successive administrations have gone to in planning for the aftermath of a nuclear assault, Graff deftly weaves a tale of secrecy and paranoia” (The New York Times Book Review) with details "that read like they've been ripped from the pages of a pulp spy novel" (Vice). For more than sixty years, the US government has been developing secret Doomsday strategies to protect itself, and the multibillion-dollar Continuity of Government (COG) program takes numerous forms—from its potential to evacuate the Liberty Bell from Philadelphia to the plans to launch nuclear missiles from a Boeing-747 jet flying high over Nebraska. Garrett M. Graff sheds light on the inner workings of the 650-acre compound, called Raven Rock, just miles from Camp David, as well as dozens of other bunkers the government built for its top leaders during the Cold War, from the White House lawn to Cheyenne Mountain in Colorado to Palm Beach, Florida, and the secret plans that would have kicked in after a Cold War nuclear attack to round up foreigners and dissidents and nationalize industries. Equal parts a presidential, military, and cultural history, Raven Rock tracks the evolution of the government plan and the threats of global war from the dawn of the nuclear era through the War on Terror.
