As the major powers engaged in an arms race in the early years of the 20th century, the Admiralty was tasked with developing that deadly stalker of the high seas - the submarine. In 1905, briefed with creating a vessel that could be employed on an enemy's coastline, the Admiralty took several technological leaps forward to match Germany's own revolutionary vessels. Written by an influential expert in the field and covering all classes of submarine developed and deployed during the war, this book includes great technical detail, gripping operational accounts and is accompanied by artwork. With fascinating details of daring submarine raids in the Baltic and the Dardanelles, this book reveals the exceedingly dangerous world of early submarine warfare which claimed an extraordinary number of lives on both sides and paved the way for a new kind of naval warfare in the 20th century and beyond.

An “indispensable” guide to the Royal Navy’s submarines through 1945, with numerous photos and original plans (The Naval Review). The Royal Navy didn’t invent the submarine—but in 1914, Britain had the largest submarine fleet in the world, and at the end of World War I it had some of the largest and most unusual of all submarines—whose origins and designs are all detailed in this book. During the First World War they virtually closed the Baltic to German iron ore traffic, and blocked supplies to the Turkish army at Gallipoli. They were a major element in the North Sea battles, and fought the U-boat menace. During World War II, US submarines were known for strangling Japan, but lesser known is the parallel battle by British submarines in the Mediterranean to strangle the German army in North Africa. Like their US counterparts, interwar British submarines were designed largely with the demands of a possible Pacific War, though that was not the war they fought. The author also shows how the demands of such a war, fought over vast distances, collided with interwar British Government attempts to limit costs. It says much about the ingenuity of British submarine designers that they met their requirements despite enormous pressure. The author shows how evolving strategic and tactical requirements and evolving technology produced successive types of design. British submariners contributed much to the development of anti-submarine tactics and technology, beginning with largely unknown efforts before World War I. Between the wars, they exploited the new technology of sonar (Asdic), and as a result pioneered submarine silencing, with important advantages to the US Navy as it observed the British. They also pioneered the vital postwar use of submarines as anti-submarine weapons, sinking a U-boat while both were submerged. Heavily illustrated with photos and original plans and incorporating much original analysis, this book is ideal for naval historians and enthusiasts. “Sure to become the standard reference for British submarine development for years to come” —Warship

The first comprehensive technical history on the subject, with photos: “A must-read for all professionals, designers and scholars of modern submarines.” —Australian Naval Institute The Royal Navy’s greatest contribution to the Allied success in World War II was undoubtedly the defeat of the U-boat menace in the North Atlantic, a victory on which all other European campaigns depended. The underwater threat was the most serious naval challenge of the war, so it was not surprising that captured German submarine technology became the focus of attention for the British submarine service after 1945. It was quick to test and adopt the schnorkel, streamlining, homing torpedoes, and, less successfully, hydrogen-peroxide propulsion. Furthermore, in the course of the long Atlantic battle, the Royal Navy had become the world’s most effective anti-submarine force and was able to utilize this expertise to improve the efficiency of its own submarines. However, in 1945 German submarine technology had also fallen into the hands of the Soviet Union—and as the Cold War developed it became clear that a growing Russian submarine fleet would pose a new threat. Britain had to go to the US for its first nuclear propulsion technology, but the Royal Navy introduced the silencing technique that made British and US nuclear submarines viable anti-submarine assets, and it pioneered in the use of passive—silent—sonars in that role. Nuclear power also changed the role of some British submarines, which replaced bombers as the core element of British Cold War and post-Cold War nuclear deterrence. As in other books in this series, this one shows how a combination of evolving strategic and tactical requirements and new technology produced successive types of submarines. It is based largely on unpublished and previously classified official documentation, and to the extent allowed by security restrictions, also tells the operational story—HMS Conqueror is still the only nuclear submarine to have sunk a warship in combat, but there are many lesser-known aspects of British submarine operations in the postwar era.

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.

Sea Wolves is the story of the crews who bravely manned British submarines in the Second World War. This small band of highly trained and highly skilled individuals fought in the front line for six long years, undertaking some of the most dangerous missions of the war. Britain's Sea Wolves operated close to shore in mined waters, attacking German warships and heavily guarded convoys. But in the course of these vital operations, the submariners suffered devastating casualties. This is the vivid, thrilling story of the survivors and their promising young comrades who fought with such courage, in the face of the sickening terror. 'Clayton's pages are peopled with eccentrics . . . Full of the picturesque detail of cramped submarine life . . . the monotonously throbbing engines; the sudden panic dives; the smells of oil, unwashed bodies and rotting food; the stifling lack of space . . . Sea Wolves is a fine memorial to these men' Nigel Jones, Literary Review

Submarines played a major role in the war at sea in the years 1939-45, and this major reference book describes all the classes of vessel that were deployed by the eighteen combatant nations during those years. They were responsible for the sinking of 33 million tons of merchant shipping, with the German and U.S. navies achieving the greatest advantage with this devastating strategic weapon. This new edition of a classic work has been completely redesigned and overhauled to make the most of the author's superb collection of photographs and will appeal to a wide new audience for whom this important work has been unavailable for many years.

Originally designed in 1934 for anti-submarine training, by the end of the war 72 U-Class subs had been commissioned; 17 were lost to the enemy, and 3 in accidents. Manned by crews from seven nations' navies, they served worldwide, and never more successfully than in the Mediterranean. This book is the definitive study of this class of submarine and the men who serve on them.
