32 in 44 - Building the Portsmouth Submarine Fleet in World War II

   In 1944 Portsmouth Navy Yard launched three submarines and a fourth shortly thereafter. Prior to this, no shipyard had ever accomplished either feat. Those three first submarines, called Ronquil, Redfish, and Razorback were delivered at 1:00 PM and the Scabbard fish slid down building way into the Piscataqua River at 2:30 PM. These four submarines would be included in the record-setting thirty-two submarines that the yard completed in 1944. No american shipyard has ever built so many submarines during one year, this is where the name of this study is coming from. Prior to that triple launching. Fred White, the shipyard's master rigger, had concerns about floating three 1.800-ton submarines off their blocks at the same time. Three above mentioned submarines were jammed into the dry dock with little separation, and White and his line handlers were the ones responsible for ensuring that the submarines did not damage each other as they floated free of the blocks...

Silent Killers - Submarines and Underwater Warfare

   The premise and promise of the submarine as a means to reach Earth's last frontier, the depths of the ocean, has grasped public attention for hundreds of years, and in the last century the potential of the submarine as an instrument of war has increasingly commanded the attention of military minds. From hand-cranks, steam, electrical batteries and diesel to nuclear power, and from hand-set explosive charges to nuclear missiles, the submarine and the armaments it can deploy have made it the world's ultimate naval weapon. The earliest wooden submarines have given rise to modern, titanium-hulled, fast, deep-diving, and stealthy "silent killers" that can strike from anywhere in the world where there is deep water — even through thick Arctic ice. As an archaeologist with an interest in the role of technology in shaping society, I have long been fascinated by the development of the submarine.That interest has been honed by incredible experiences and opportunities to work with submarines. This has included archaeological and historical research into the Type A Japanese Midget submarines of the 1930s and 1940s and the detailed analysis of a misidentified Japanese submarine in the Mariners' Museum in Newport News, Virginia (US), said to be a sponge-diving craft but actually one of Japan's top secret prewar prototypes for its Midget submarine force.

U-Boats in Action

   Here is the very first book in a long series of "Warship in Action" books from Squadron/Signal Publications. The emphasis has been given by authors, Robert C. Stern & Don Greer, on individual histories and physical description rather than an overall views of the underwater boat war. This publication is intended to fill the vacant niche in the marine literature on this subject available today, a type-by-type surveys of Kiegsmarine submarines, explaining the development of thiose boats and success/failure in meeting the demands of war. It gives so much valuable information for everyone interested in the history of fleet, sea wars, naval warships and submarines of the past. This information is supplemented by rare original photographs of various U-biats with their role in World War Two explained.

U.S. Ballistic Missile Subs In Action

   During 1942, two Germans. Doctor Ernest Steinhoff, a Peenemunde rocket scientist working for Werner Von Braun, and his brother С APT Fritz Steinhoff. of the U-551 contrived a plan to install rockets on a U-Boat. A Type V1IC U-Boat was fitted with a rack that could hold six 300мм Wurfkoper42 Spreng tactical rockets. The tests were successful and a launch was made from a depth of twelve meters. The test results were shown to ADM Karl Donitz and his staff, but the idea was turned down as impractical and of no value to the German war effort. Additionally, it was felt that it would tie up a fleet of U-boats that could be used to sink allied convoys. During 1943. a plan was devised to place German A-4 (V-2) rockets in floating containers and then tow them by U-Boat to the United States. Once offshore, their ballast tanks would be filled with water, righting the container. Then the missiles would be fired at major cities on the U.S. East Coast. Contracts were actually let to the Stettin Shipyard in Poland for three such containers for test purposes, but by the time the war ended none had been produced. Following the end of World War II. many German scientists fell into the hands of the Americans and Soviets and a number of them were brought to the United States and the Soviet Union. The Soviets experimented with the containerized rocket idea, while early U.S. tests focused on the German FZG-76 (V-l) Buzz Bomb. Called the Loon in Navy service, the captured Buzz Bombs were as dangerous to the sub's crew as to the enemy and many missiles exploded during launch. In 1947, the Navy began to experiment with the launching of the Loon and later Regulus I and Regulus II missiles from the decks of surfaced submarines...

U-Boats - History, Development and Equipment 1914-1945

   This book looks al the various classes of U-boat and their various weapons and sensors, and at the men who manned them and conducted this very protracted and hard fought campaign. It is divided into four parts: Part One - covers the U-boat in German naval service from the very earliest days, through its first great test in World War I to the clandestine campaign between 1919 and 1935, which was designed to keep U-boat technology and practice alive, despite the terms of the Versailles Treaty. Part Two - covers the major technological areas in the period 1935-1945, including descriptions of the various types of U-boat, their weapons, communications, sensors, and propulsion systems. Part Three - describes the campaigns, the men, their training, the sorry saga of Luftwaffe co-operation, U-boat losses, and the end of the campaign. Appendix at the end of the book is devoted to the U-boats lost at sea in the perioe 1939-1945.

Grey Wolves of the Sea - German U-Boat Type VII

   This revised edition of Grey Wolves of the Sea is devoted by the author, Heinz J. Nowarra, to the history of the most frequently built German types of submarine. The book is somewhat similar to the Squadron Signal giving the reader a brief history of the Typy VII underwater boats and all subtypes. Though all illustrations inside the book are black-and-white, they give people quite clear idea of how deadly and efficient those machines were.
