Available in PDF, EPUB and Kindle. Book excerpt: In the foreword to this book, first published in 1978, Sen. Daniel Inouye describes the story as ""the raw material of adventure fiction--but this is all true and told in a manner that is at the same time fascinating and professional."" Despite the passage of twenty years and the appearance of several studies of code breaking, this inside look at naval intelligence in the Pacific is as powerful as ever. This book provides a compassionate and unique understanding of the war and the business of intelligence gathering. Assigned to the combat intelligence unit in Honolulu from June 1941 to the end of the war, W. J. Holmes shares his history-making experiences as part of an organization that collected, analyzed, and disseminated naval intelligence throughout World War II. His book not only captures the mood of the period but gives rare insight into the problems and personalities involved, allowing the reader to fully appreciate the painful moral dilemma faced daily by commanders in the Pacific once the Japanese naval codes were broken. Every time the Americans made use of the enemy messages they had decoded, they increased the probability of the Japanese realizing what had happened and changing their codes. And such a change would cause the U.S. Pacific Fleet to lose a vital edge. On the other hand, withholding the information could--and sometimes did--result in the loss of U.S. lives and ships. This revealing study illuminates the difficulties in both collecting intelligence and deciding when to use it.

Download or read book Japanese Intelligence in World War II written by Ken Kotani and published by Osprey Publishing. This book was released on 2009-09-22 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the eyes of history, Japanese intelligence in World War II has fared very poorly. However, these historians have most often concentrated on the later years of the war, when Japan was fighting a multi-front war against numerous opponents. In this groundbreaking new study, Japanese scholar Ken Kotani re-examines the Japanese Intelligence department, beginning with the early phase of the war. He points out that without the intelligence gathered by the Japanese Army and Navy they would have been unable to achieve their long string of victories against the forces of Russia, China, and Great Britain. Notable in these early campaigns were the successful strikes against both Singapore and Pearl Harbor. Yet as these victories expanded the sphere of Japanese control, they also made it harder for the intelligence services to gather accurate information about their growing list of adversaries. At the battle of Midway in 1942, Japanese intelligence suffered its worst mishap when the Americans broke their code and tricked the Japanese into revealing the target of their attack. It was a mistake from which they would never recover. As the military might of Japan was forced to retreat and her forces deteriorated, so too did her intelligence services.

Download or read book Pearl Harbor Revisited written by Frederick D. Parker and published by CreateSpace. This book was released on 2012-07-31 with total page 104 pages. Available in PDF, EPUB and Kindle. Book excerpt: This is the story of the U.S. Navy's communications intelligence (COMINT) effort between 1924 and 1941. It races the building of a program, under the Director of Naval Communications (OP-20), which extracted both radio and traffic intelligence from foreign military, commercial, and diplomatic communications. It shows the development of a small but remarkable organization (OP-20-G) which, by 1937, could clearly see the military, political, and even the international implications of effective cryptography and successful cryptanalysis at a time when radio communications were passing from infancy to childhood and Navy war planning was restricted to tactical situations. It also illustrates an organization plagues from its inception by shortages in money, manpower, and equipment, total absence of a secure, dedicated communications system, little real support or tasking from higher command authorities, and major imbalances between collection and processing capabilities. It explains how, in 1941, as a result of these problems, compounded by the stresses and exigencies of the time, the effort misplaced its focus from Japanese Navy traffic to Japanese diplomatic messages. Had Navy cryptanalysts been ordered to concentrate on the Japanese naval messages rather than Japanese diplomatic traffic, the United States would have had a much clearer picture of the Japanese military buildup and, with the warning provided by these messages, might have avoided the disaster of Pearl Harbor.

Download or read book Joe Rochefort s War written by Elliot W Carlson and published by Naval Institute Press. This book was released on 2013-09-15 with total page 626 pages. Available in PDF, EPUB and Kindle. Book excerpt: Elliot Carlson’s award-winning biography of Capt. Joe Rochefort is the first to be written about the officer who headed Station Hypo, the U.S. Navy’s signals monitoring and cryptographic intelligence unit at Pearl Harbor, and who broke the Japanese navy’s code before the Battle of Midway. The book brings Rochefort to life as the irreverent, fiercely independent, and consequential officer that he was. Readers share his frustrations as he searches in vain for Yamamoto’s fleet prior to the Japanese attack on Pearl Harbor, but share his joy when he succeeds in tracking the fleet in early 1942 and breaks the code that leads Rochefort to believe Yamamoto’s invasion target is Midway. His conclusions, bitterly opposed by some top Navy brass, are credited with making the U.S. victory possible and helping to change the course of the war. The author tells the story of how opponents in Washington forced Rochefort’s removal from Station Hypo and denied him the Distinguished Service Medal recommended by Admiral Nimitz. In capturing the interplay of policy and personality and the role played by politics at the highest levels of the Navy, Carlson reveals a side of the intelligence community seldom seen by outsiders. For a full understanding of the man, Carlson examines Rochefort’s love-hate relationship with cryptanalysis, his adventure-filled years in the 1930s as the right-hand man to the Commander in Chief of the U.S. Fleet, and his return to codebreaking in mid-1941 as the officer in charge of Station Hypo. He traces Rochefort’s career from his enlistment in 1918 to his posting in Washington as head of the Navy’s codebreaking desk at age twenty-five, and beyond. In many ways a reinterpretation of Rochefort, the book makes clear the key role his codebreaking played in the outcome of Midway and the legacy he left of reporting actionable intelligence directly to the fleet. An epilogue describes efforts waged by Rochefort’s colleagues to obtain the medal denied him in 1942—a drive that finally paid off in 1986 when the medal was awarded posthumously.
Download or read book The Imperial Japanese Navy in the Pacific War written by Mark Stille and published by Bloomsbury Publishing. This book was released on 2014-11-20 with total page 457 pages. Available in PDF, EPUB and Kindle. Book excerpt: An highly illustrated examination of the key ships, tactics and operations of the Imperial Japanese Navy in the War in the Pacific in World War II. The Imperial Japanese Navy (IJN) was the third most powerful navy in the world at the start of World War II, and came to dominate the Pacific in the early months of the war. This was a remarkable turnaround for a navy that only began to modernize in 1868, although defeats inflicted on the Russians and Chinese in successive wars at the turn of the century gave a sense of the threat the IJN was to pose. Bringing together for the first time material previously published in Osprey series books, and with the addition of new writing making use of the most recent research, this book details the Japanese ships which fought in the Pacific and examines the principles on which they were designed, how they were armed, when and where they were deployed and how effective they were in battle. The Imperial Japanese Navy in the Pacific War provides a history of the IJN's deployment and engagements, analysis of the evolution of strategy and tactics, and finally addresses the question of whether it truly was a modern navy, fully prepared for the rigors of combat in the Pacific. Illustrated throughout with photographs and detailed colour artworks, this is a valuable reference source for Pacific War enthusiasts and historians alike.
Download or read book Imperial Japanese Navy Aircraft Carriers 1921 45 written by Mark Stille and published by Bloomsbury Publishing. This book was released on 2012-05-20 with total page 102 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Imperial Japanese Navy was a pioneer in naval aviation, having commissioned the world's first built-from-the-keel-up carrier, the Hosho. Throughout the 1920s and 1930s, it experimented with its carriers, perfecting their design and construction. As a result, by the time Japan entered World War II and attacked the United States at Pearl Harbor in 1941, it possessed a fantastically effective naval aviation force. This book covers the design, development and operation of IJN aircraft carriers built prior to and during World War II. Pearl Harbor, Midway and the first carrier vs carrier battle, the battle of the Coral Sea, are all discussed.

This book was released on 2015-12-16 with total page 575 pages. Available in PDF, EPUB and Kindle. Book excerpt: This unique reference presents 59 biographies of people who were key to the sea services being reasonably prepared to fight the Japanese Empire when the Second World War broke out, and whose advanced work proved crucial. These intelligence pioneers invented techniques, procedures, and equipment from scratch, not only allowing the United States to hold its own in the Pacific despite the loss of most of its Fleet at Pearl Harbor, but also laying the foundation of today’s intelligence methods and agencies. One-hundred years ago, in what was clearly an unsophisticated pre-information era, naval intelligence (and foreign intelligence in general) existed in rudimentary forms almost incomprehensible to us today. Founded in 1882, the U.S. Office of Naval Intelligence (ONI)—the modern world’s “oldest continuously operating intelligence agency”—functioned for at least its first forty years with low manning, small budgets, low priority, and no prestige. The navy’s early steps into communications intelligence (COMINT), which included activities such as radio interception, radio traffic analysis, and cryptology, came with the 1916 establishment of the Code and Signals Section within the navy’s Division of Communications and with the 1924 creation of the “Research Desk” as part of the Section. Like ONI, this COMINT organization suffered from low budgets, manning, priority, and prestige. The dictionary focuses on these pioneers, many of whom went on, even after World War II, to important positions in the Navy, the State Department, the Armed Forces Security Agency, the National Security Agency, and the Central Intelligence Agency. It reveals the work and innovations of well and lesser-known individuals who created the foundations of today’s intelligence apparatus and analysis.
Download or read book Naval Ship Models of World War II in 1 1250 and 1 1200 Scales written by Robert K. Liu and published by Seaforth Publishing. This book was released on 2021-02-28 with total page 336 pages. Available in PDF, EPUB and Kindle. Book excerpt: A guide for collectors and modelers—packed with photos, technical information, practical advice, and history. The origins of 1/1250 and 1/1200 scale models can be traced back to the first years of the twentieth century and their use as identification aids by the military during the First World War. When peace came, the manufacturers aimed their increasingly sophisticated products at collectors, and ever since then acquiring, enhancing, modifying, or scratch-building miniature ship models has been an avidly pursued hobby around the world. This new book focuses on models of the ships of the Second World War, and the author addresses all the practical issues that might confront collectors who like to enhance, convert, and modify their models, or even scratch-build models of ships not commercially available. The book covers both Allied and Axis warships, naval airplanes, merchant conversions, and even an Italian armed schooner, and provides historic and technical information on the ships represented as well as practical advice on modeling them—including twenty-five chapters covering everything from initial production techniques such as spin casting, silicon mold casting, resin casting, die-casting, plastic mold injection, and 3D printing through techniques for enhancing and modifying models to eventually researching and scratch-building an uncommon ship or type. The focus is always on particular vessels and the vast array covered builds into a fascinating panorama of the vessels that fought across the world’s oceans in that era. The combination of intriguing background and historical information, combined with detailed practical information and more than 300 stunning photographs, makes this book irresistible to collectors, modelers, or anyone with an interest in the navies of the Second World War.
Download or read book Agents of Innovation written by John Trost Kuehn and published by Naval Institute Press. This book was released on 2008-11-01 with total page 296 pages. Available in PDF, EPUB and Kindle. Book excerpt: Agents of Innovation examines the influence of the General Board of the Navy as agents of innovation during the period between World Wars I and II. The General Board, a formal body established by the Secretary of the Navy to advise him on both strategic matters with respect to the fleet, served as the organizational nexus for the interaction between fleet design and the naval limitations imposed on the Navy by treaty during the period. Particularly important was the General Board’s role in implementing the Washington Naval Treaty that limited naval armaments after 1922. The General Board orchestrated the efforts by the principal Naval Bureaus, the Naval War College, and the Office of the Chief of Naval Operations in ensuring that the designs adopted for the warships built and modified during the period of the Washington and London Naval Treaties both met treaty requirements while attempting to meet strategic needs. The leadership of the Navy at large, and the General Board in particular, felt themselves especially constrained by Article XIX (the fortification clause) of the Washington Naval Treaty that implemented a status quo on naval fortifications in the Western Pacific. The treaty system led the Navy to design a measurably different fleet than it might otherwise have in the absence of naval limitations. Despite these limitations, the fleet that fought the Japanese to a standstill in 1942 was predominately composed of ships and concepts developed and fostered by the General Board prior to the outbreak of war.
Download or read book The Japanese Submarine Force and World War II written by Akihiko Yoshida and published by Naval Institute Press. This book was released on 2013-01-15 with total page 293 pages. Available in PDF, EPUB and Kindle. Book excerpt: When first published in 1995, this book was hailed as an absolutely indispensable contribution to the history of the Pacific War. Drawing heavily from Japanese sources and American wartime intercepts of secret Japanese radio messages, a noted American naval historian and a Japanese mariner painstakingly recorded and evaluated a diverse array of material about Japan's submarines in World War II. The study begins with the development of the first Japanese 103-ton Holland-type submergible craft in 1905 and continues through the 1945 surrender of the largest submarine in the world at the time, the 5300-ton I-400 class that carried three airplanes. Submarine weapons, equipment, personnel, and shore support systems are discussed first in the context of Japanese naval preparations for war and later during the war. Both successes and missed opportunities are analyzed in operations ranging from the California coast through the Pacific and Indian Oceans to the coast of German-occupied France. Appendixes include lists of Japanese submarine losses and the biographies of key Japanese submarine officers. Rare illustrations and specifically commissioned operational maps enhance the text.

Download or read book The United States Navy in World War II written by Mark Stille and published by Bloomsbury Publishing. This book was released on 2021-11-11 with total page 396 pages. Available in PDF, EPUB and Kindle. Book excerpt: A comprehensive overview of the strategy, operations and vessels of the United States Navy from 1941 to 1945. Although slowly building its navy while neutral during the early years of World War II, the US was struck a serious blow when its battleships, the lynchpin of US naval doctrine, were the target of the dramatic attack at Pearl Harbor. In the Pacific Theatre, the US was thereafter locked into a head to head struggle with the impressive Imperial Japanese Navy, fighting a series of major battles in the Coral Sea, at Midway, the Philippine Sea, Leyte Gulf and Okinawa in the struggle for supremacy over Japan. Having avoided the decisive defeat sought by the IJN, the US increased industrial production and by the end of the war, the US Navy was larger than any other in the world. Meanwhile in the west, the US Navy operated on a second front, supporting landings in North Africa, Sicily, and Italy, and in 1944 played a significant part in the D-Day landings, the largest and most complex amphibious operation of all time. Written by an acknowledged expert and incorporating extensive illustrations including photographs, maps and colour artwork, this book offers a detailed look at the strategy, operations and vessels of the US Navy in World War II.
