The submarine was undoubtedly the most potent purely naval weapon of the twentieth century. In two world wars, enemy underwater campaigns were very nearly successful in thwarting Allied hopes of victory - indeed, annihilation of Japanese shipping by US Navy submarines is an indicator of what might have been. That the submarine was usually defeated is a hugely important story in naval history, yet this is the first book to treat the subject as a whole in a readable and accessible manner. It concerns individual heroism and devotion to duty, but also ingenuity, technical advances and originality of tactical thought. What developed was an endless battle between forces above and below the surface, where a successful innovation by one side eventually produces a counter-measure by the other in a lethal struggle for supremacy. Development was not a straight line: wrong ideas and assumptions led to defeat and disaster.

A deep dive into the tactics and technology used to defend against submarines—from the opening of the First World War through World War II and beyond. The submarine was undoubtedly the most potent purely naval weapon of the twentieth century. In two world wars, enemy underwater campaigns were very nearly successful in thwarting Allied hopes of victory—indeed, annihilation of Japanese shipping by US Navy submarines is an indicator of what might have been. That the submarine was usually defeated is a hugely important story in naval history, yet this is the first book to treat the subject as a whole in a readable and accessible manner.

Development was not a straight line: wrong ideas and assumptions led to defeat and disaster. “Iconography (with dozens of photographs and often large-format diagrams), a vast bibliography and a complete and documented general approach make this volume a work of great quality and of great interest for all enthusiasts and scholars of this very interesting subject.”—Storia Militare “The modeller will not only find the text engaging but there is a superb collection of photographs and illustrations which of course include submarines, corvettes and destroyers. Subjects which the modeller increasingly appreciates. Highly recommended.”—Model Boats

Investigating the employment of British aircraft against German submarines during the final years of the First World War, this new book places anti-submarine campaigns from the air in the wider history of the First World War. The Royal Naval Air Service invested heavily in aircraft of all types—aeroplanes, seaplanes, airships, and kite balloons—in order to counter the German U-boats. Under the Royal Air Force, the air campaign against U-boats continued uninterrupted. Aircraft bombed German U-boat bases in Flanders, conducted area and ‘hunting’ patrols around the coasts of Britain, and escorted merchant convoys to safety. Despite the fact that aircraft acting alone destroyed only one U-boat during the war, the overall contribution of naval aviation to foiling U-boat attacks was significant. Only five merchant vessels succumbed to submarine attack when convoyed by a combined air and surface escort during World War I. This book examines aircraft and weapons technology, aircrew training, and the aircraft production issues that shaped this campaign. Then, a close examination of anti-submarine operations—bombing, patrols, and escort—yields a significantly different judgment from existing interpretations of these operations. This study is the first to take an objective look at the writing and publication of the naval and air official histories as they told the story of naval aviation during the Great War. The author also examines the German view of aircraft effectiveness, through German actions, prisoner interrogations, official histories, and memoirs, to provide a comparative judgment. The conclusion closes with a brief narrative of post-war air anti-submarine developments and a summary of findings. Overall, the author concludes that despite the challenges of organization, training, and production the employment of aircraft against U-boats was largely successful during the Great War. This book will be of interest to historians of naval and air power history, as well as students of World War I and military history in general.

World War I was the crucible of antisubmarine warfare (ASW), and the years of trial and error between 1914 and 1918 gave rise to the weapons and tactics used by today's ASW forces. With this study, military historian Dwight Messimer examines the weapons, tactics, and organization used by all the belligerents during the war and provides some surprising findings. Because he draws heavily from personal accounts as well as from official records, his book will appeal to both serious readers seeking hard facts and to general readers who like stories about war at sea. Messimer tells the story from both sides. German survivors who escaped from sunken U-boats explain what it was like to face the newly developed ASW weapons beneath the surface, and pilots tell what it was like from above. The author describes the German's well-organized and efficient ASW organization in the Baltic and the Helgoland Bight. He also discusses the weapons developed during the war that proved to be largely ineffective or outright failures. While his evaluations of the contributions made by aircraft and Q-ships put them in the category of only marginally effective, his analysis of the effectiveness of politics deems that ASW "weapon" the most effective of all. Solidly grounded in the best primary sources available in England, the United States, and Germany, this book is the first to address the ASW of all World War I belligerents.

In this book, Michael Glynn explores a journey through the history of more than one hundred years of aerial sub hunting. From the Great War, through the Battle of the Atlantic in World War II and on to the secret confrontations of the Cold War, the reader will witness the parallel evolution of both aircraft and submarine as each side tries to gain supremacy over the other. In so doing, Glynn distills complicated oceanography, operations analysis, and technical theory into easily digested concepts, helping the reader understand how complex weapons and sensors function. By reviewing the steps of a submarine hunting flight, the reader can quickly understand how theory and practice fit together and how aviators set out to achieve their goal of detecting their submarine targets. Airborne Anti-Submarine Warfare is a thrilling read for those seeking a glimpse into an arcane and high-stakes world.
