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.

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.

The history of the development of submarines covered in this book spans the most tumultuous years of the 20th century. When the little Holland No. 1 was launched in 1901, few could guess that the submarine would become the most potent weapon of war ever developed.

An illustrated account of the war beneath the waves, this reference covers: the first submarines; WW1; WW2; Cold War submarine operations; and submarines of the future. It covers anti-submarine warships and weapons as well as the submarines.

Sea Devils is a compelling account of pioneer submariners and their astonishing underwater contraptions. Some made perilous voyages. Others sank like stones. Craft were propelled by muscle-power or had steam engines with chimneys. Some had wheels to trundle along the seabed. Others were used as underwater aircraft carriers. Here John Swinfield traces the history of early submarines and the personalities who built and sailed them. From a plethora of madcap inventors emerged a bizarre machine that navies of the world reluctantly acquired but viewed with distaste. It matured into a weapon that would usurp the mighty battleship, which had for centuries enjoyed an unchallenged command of the oceans. In its long and perilous history the submarine became subject to fierce business, military and political shenanigans. It won eventual acceptance amidst the chaos and carnage of the First World War, in which pathfinder submariners achieved an extraordinarily high tally of five Victoria Crosses, Britain's highest military decoration. Sea Devils brims with daring characters and their unflinching determination to make hazardous underwater voyages: an immensely readable, entertaining and authoritative chronicle of low cunning, high politics, wondrous heroism and appalling tragedy.
