The German U-boat Type XXI was a revolutionary marvel at the time of its development, close to the end of World War II. This book covers the history leading up to the development of the Type XXI, as well as covering the actual development and short usage of the U-boat.

2nd Edition. Until now, the underwater craft employed by the World's Special Forces have been known only to a select few. Covert Shores is the first complete and documented insight into the little-known world of the mini-subs, Swimmer Delivery Vehicles (SDVs) and other underwater vehicles used by the U. S. Navy SEALs, Special Boat Service, Spetsnaz and more. Operating under a blanket of secrecy, these craft have remained hidden and unrecorded in a way that no other class of military vehicles has. Covert Shores reveals the craft, units, missions and tactics of this unseen world. Spanning from 1776 to the present day, and covering activities in many countries including US, Great Britain, Italy, Israel, Russia, France, Germany, Yugoslavia and Sweden, this book is filled with tales of the ingenuity, resourcefulness, experimentation and cunning of those involved in the design and operations of these expert craft. A must-read for all military enthusiasts. 274 pages 8.5"x11" full color with over 100 original color illustrations.Foreword by Larry Bond

From January to July 1942, more than seventy-five ships sank to North Carolina's "Graveyard of the Atlantic" off the coast of the Outer Banks. German U-boats sank ships in some of the most harrowing sea fighting close to America's shore. Germany's Operation Drumbeat, led by Admiral Karl Donitz, brought fear to the local communities. A Standard oil tanker sank just sixty miles from Cape Hatteras. The U-85 was the first U-boat sunk by American surface forces, and local divers later discovered a rare Enigma machine aboard. Author Jim Bunch traces the destructive history of world war on the shores of the Outer Banks.

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.

This, the first of two volumes on Germany's World War II U-boats, traces their development from the early U-boats of the Kaiser's Navy, the prohibition on Germany having U-boats following the Armistice in 1918 and the subsequent Treaty of Versailles, the secret development of U-boats using a 'cover-firm' in Holland, culminating in the formation of the 1st U-boat Flotilla in 1935 with the modern Type II. The operational history section includes examples from the Classes Type VIIA, Type VIIB, VIID, VIIE and VIIF before concentrating on the mainstay of the U-boat arm, the Type VIIC. Comparisons are also made with the standard allied submarines, their strengths, weaknesses and U-boat tactics.

The Type XXI U-boot was one of the few types of weapon that, despite being unable to take part in combat, completely changed the character of naval actions at sea. It was the first true submarine in history. The other types of vessels designed so far were basically "diving ships" that might have been underwater for some time, but most of the time they had to be on the surface because their underwater range was severely limited. Under water they were slow and not maneuverable, and often had to emerge onto the surface to charge their electric batteries. The Type XXI was designed from the outset as a true submarine whose natural environment was to be the deep seas.
