The AN/SQS-26 long-range, echo-ranging sonar surpassed predecessor production sonars by adding an over-the-horizon detection capability and exploiting the surface duct, bottom bounce, and convergence zone sound propagation paths from a hull-mounted sonar on a surface ship to a submarine target. This history of the AN/SQS-26 program details the nature of the technical problems encountered and the solutions found to address them, as well as the influence of international events on the objectives and support of the program. The critical contributions made by numerous personnel and organizations to the development program are documented, and the arc of the AN/SQS-26 program's success is traced from early concept formulation through full-scale experimentation and development to operational evaluation and full deployment in the Fleet. The AN/SQS-26 served as the antisubmarine warfare (ASW) sonar on U.S. destroyers and cruisers for decades, and this versatile sonar became a key factor in the U.S. Navy's quest for ASW superiority in the Cold War era. The first edition was published by the Naval Undersea Warfare Center Division, Newport, RI, in 2003. This edition makes the historical material in the book available for use by academia, research laboratories, and fleet units interested in ASW and the principles of sonar.

Discusses the development of submarines and the history of their uses.

Developed by French physicist Auguste Piccard and his son Jacques, the bathyscaph Trieste was a scientific marvel that allowed unprecedented scientific, technical, and military feats in the ocean depths. France and the United States both acquired and subsequently developed variants of the original bathyscaph. While both France and the United States employed the bathyscaph as a tool for scientific investigation of the deepest ocean depths, the U.S. Navy developed and employed the Trieste for military missions as well. From its earliest years, participants in the Trieste program realized that they were making history, blazing a trail into previously unexplored and unexploited depths, developing new capabilities and opening a new frontier. Comparisons with developments in space and the space-race between the United States and the Soviet Union often were made concerning the Trieste program and contemporary developments in undersea technologies and capabilities. The Trieste opened the entire oceans to exploration, exploitation, and operations. The bathyscaph was a first-generation system, a "Model-T" that spawned an entirely new industry and encouraged new concepts for deep-ocean naval operations. Advances in deep-sea technologies lacked the "gee-whiz" factor of the concurrent space race, but were highly significant in the development of new technology, new knowledge, and new military capabilities. Opening the Great Depths is the story of the three Trieste deep-ocean vehicles, their officers and enlisted men, and the civilians, often told in their own words, documenting for the first time the earliest years of humanity's probing into Earth's final frontier.

Submariners are a tight knit group of men bound together by training and experience, and with a language all their own. That language is perhaps a little vulgar, but never intentionally demeaning, and a little irreverent but still worldly. This work is an attempt to preserve and explain some of these curious guys who so proudly wear a shiny metal pin that looks like a strange pair of fish on their left breast. This process of accumulating this new language begins in Boot Camp, and is added to with every change of duty station the sailor undergoes. It is heard aboard the boats and, unknowingly, by family members who can't understand terms like head, deck, and overhead, and who think SOS is a distress signal.

Ocean Ridges and Trenches, Revised Edition immerses readers in the mysteries of the world's sea floors, from the surprising creatures of the Galapagos Rift to the devastating tsunamis of the Java Trench. This eBook reveals how 10 undersea mountain ranges and valleys came to be, how and why it has changed over the span of geologic time, and its contributions to the environment. The ridges and trenches covered span the Mariana Trench, the deepest point in the ocean, and the San Andreas Fault, site of many of California’s earthquakes. Each chapter provides illuminating material on environmental challenges and expert reports on science in action, with details on field studies conducted at each sea-floor site. Additional articles cover related high-interest topics, such as giant squids, magnetic fields, and plate tectonics.
