Book Description
Ultimately, World War II was the first war won by technology, but within only a few weeks after the war began, the U.S. Navy realized its torpedo program was a dismal failure. Submarine skippers reported that most of their torpedoes were either missing the targets or failing to explode if they did hit. The United States had to work fast if it expected to compete with the Japanese Long Lance, the biggest and fastest torpedo in the world, and Germany's electric and sonar models. Hellions of the Deep tells the dramatic story of how Navy planners threw aside the careful procedures of peacetime science and initiated &"radical research&": gathering together the nation's best scientists and engineers in huge research centers and giving them freedom of experimentation to create sophisticated weaponry with a single goal&—winning the war. The largest center for torpedo work was a requisitioned gymnasium at Harvard University, where the most famous names in science worked with the best graduate students from all around the country at the business of war. They had to produce tangible weapons, to consider production and supply tactics, to take orders from the military, and, in many cases, also to teach the military how to use the weapons they developed. World War II grew into a chess match played by scientists and physicists, and it became the only war in history to be won by weapons invented during the conflict. For this book, Robert Gannon conducted numerous interviews over a twenty-year period with scientists, engineers, physicists, submarine skippers, and Navy bureaucrats, all involved in the development of the advanced weapons technology that won the war. While the search for new weapons was deadly serious, stretching imagination and resourcefulness to the limit each day, the need was obvious: American ships were being blown up daily just outside the Boston harbor. These oral histories reveal that, in retrospect, surprising even to those who went through it, the search for the &"hellions of the deep&" was, for many, the most exciting period of their lives.

Book Description
From the American entry into World War II until September 1943, U.S. submarines experienced an abnormally high number of torpedo failures. These failures resulted from three defects present in the primary torpedo of the day, the Mark XIV. These defects were a tendency to run deeper than the set depth, the frequent premature detonation of the Mark 6 magnetic influence exploder, and the failure of the contact exploder when hitting a target at the textbook ninety-degree angle. Ironically, despite using a completely independent design, the Germans experienced the same three defects. The Germans, however, fixed their defects in six months, while it took the Americans twenty-two months. Much of the delay on the American side resulted from the denial of senior leaders in the operational forces and in the Navy's Bureau of Ordnance (BuOrd) that the torpedo itself was defective. Instead, they blamed crews for poor marksmanship or lack of training. In the end, however, the submarine force itself overcame the bureaucratic inertia and correctly identified and fixed the three problems on their own, proving once again the industry of the average American soldier or sailor. From the American entry into World War II until September 1943, U.S. submarines experienced an abnormally high number of torpedo failures. These failures resulted from three defects present in the primary torpedo of the day, the Mark XIV. These defects were a tendency to run deeper than the set depth, the frequent premature detonation of the magnetic influence exploder, and the failure of the contact exploder when hitting a target at the textbook 90-degree angle. Ironically, despite using a completely independent design, the Germans experienced the same three defects. The Germans, however, fixed their defects in six months, while it took the Americans 22 months. Much of the delay on the American side resulted from the denial of senior leaders in the operational forces and in the Navy's Bureau of Ordnance (BuOrd) that the torpedo itself was defective. Instead, they blamed crews for poor marksmanship or lack of training. In the end, however, the submarine force itself overcame the bureaucratic inertia and correctly identified and fixed the three problems on their own, proving once again the industry of the average American soldier or sailor. Contrary to the interpretations of most submarine historians, this book concludes that BuOrd did not sit idly by while torpedoes failed on patrol after patrol. BuOrd acknowledged problems from early in the war, but their processes and their tunnel vision prevented them from realizing that the weapon sent to the fleet was grossly defective. One of World War II's forgotten heroes, Admiral Lockwood drove the process for finding and fixing the three major defects. This is first book that deals exclusively with the torpedo problem, building its case out of original research from the archives of the Bureau of Ordnance, the Chief of Naval Operations, Vice Admiral Lockwood's personal correspondence, and records from the British Admiralty at the National Archives of the United Kingdom. These sources are complemented by correspondence and interviews with men who actually participated in the events.

Book Description
The Department of the Navy strives to maintain, through its Office of Naval Research (ONR), a vigorous science and technology (S&T) program in those areas considered critically important to U.S. naval superiority in the maritime environment, including littoral waters and shore regions. In pursuing its S&T investments in such areas, ONR must ensure that (1) a robust U.S. research capability to work on long-term S&T problems in areas of interest to the Department of the Navy and the Department of Defense is sustained, (2) an adequate supply of new scientists and engineers in these areas is maintained, and (3) S&T products and processes necessary to ensure future superiority in naval warfare are provided. One of the critical areas for the Department of the Navy is undersea weapons. An Assessment of Undersea Weapons Science and Technology assesses the health of the existing Navy program in undersea weapons, evaluates the Navy's research effort to develop the capabilities needed for future undersea weapons, identifies non-Navy-sponsored research and development efforts that might facilitate the development of such advanced weapons capabilities, and makes recommendations to focus the Navy's research program so that it can meet future needs.

Book Description
GAO reviewed the Navy's MK-48 Advanced Capability (ADCAP) torpedo propulsion system upgrade program, focusing on whether the: (1) Navy needs an upgraded propulsion system; (2) upgrade would meet Navy noise reduction requirements; and (3) Navy is conducting research in alternative noise reduction technology. GAO found that: (1) the current system would meet the Navy's requirements for the SSN-21 Seawolf submarine; (2) the Seawolf will have a very limited production run; (3) the Navy is continuing the development of the upgrade and will make it available to submarines that can fire MK-48 ADCAP torpedoes, although they operate at higher noise levels than the Seawolf, which limits the value of the quieter system; (4) the upgrade was not intended to meet and will not lead to meeting the Navy's 1986 noise reduction requirements; (5) the Navy has basic and exploratory research programs in alternative noise reduction technologies; and (6) cancelling the upgrade and continuing the other research would be in line with the Department of Defense's (DOD) revised weapons acquisition strategy.

Book Description
An encyclopedic study of the ship-killer par excellence—from its development to post-World War II usage. “A well-written book, lavishly illustrated.” —International Journal of Maritime History The torpedo was the greatest single game-changer in the history of naval warfare. For the first time it allowed a small, cheap torpedo-firing vessel—and by extension a small, minor navy—to threaten the largest and most powerful warships afloat.The traditional concept of seapower, based on huge fleets of expensive capital ships, required radical rethinking because of this important naval weapon. This book is a broad-ranging international history of the weapon, tracing not only its origins and technical progress down to the present day, but also its massive impact on all subsequent naval wars. Torpedo contains much new technical information that has come to light over the past thirty years and covers all of the improved capabilities of the weapon. Heavily illustrated with photos and technical drawings this is a book no enthusiast or historian can afford to miss. “The torpedo—one of the most fearsome weapons ever created by man—is well worth its own history.” —Forum Navale

Book Description
When President Eisenhower referred to the “military–industrial complex” in his 1961 Farewell Address, he summed up in a phrase the merger of government and industry that dominated the Cold War United States. In this bold reappraisal, Katherine Epstein uncovers the origins of the military–industrial complex in the decades preceding World War I, as the United States and Great Britain struggled to perfect a crucial new weapon: the self-propelled torpedo. Torpedoes epitomized the intersection of geopolitics, globalization, and industrialization at the turn of the twentieth century. They threatened to revolutionize naval warfare by upending the delicate balance among the world’s naval powers. They were bought and sold in a global marketplace, and they were cutting-edge industrial technologies. Building them, however, required substantial capital investments and close collaboration among scientists, engineers, businessmen, and naval officers. To address these formidable challenges, the U.S. and British navies created a new procurement paradigm: instead of buying finished armaments from the private sector or developing them from scratch at public expense, they began to invest in private-sector research and development. The inventions emerging from torpedo R&D sparked legal battles over intellectual property rights that reshaped national security law. Blending military, legal, and business history with the history of science and technology, Torpedo recasts the role of naval power in the run-up to World War I and exposes how national security can clash with property rights in the modern era.
