This fully illustrated series offers detailed descriptions of the evolution of all classes of the principle U.S. combatant types, as well as plans, profiles, and numerous detailed photographs. Battleship Bismarck is a marine forensics analysis and engineering study of the design, operation, and loss of Germany\'s greatest battleship, drawing on survivors\' accounts and the authors\' combined decades of experience in naval architecture and command at sea. The investigation has covered fifty-six years of painstaking research, during which the authors conducted extensive interviews and correspondence with the ship\'s designers and survivors of the Battle of Denmark Strait and Bismarck\'s final battle. Albert Schnarke, former gunnery officer of DKM Tirpitz, sister ship of Bismarck, aided greatly by translating and circulating early manuscript materials to those who participated in the design and operation. Survivors of Bismarck\'s engagements actively contributed to this comprehensive study, including Vice Admiral (then Lieutenant) D.B.H Wildish (RN), damage control officer aboard HMS Prince of Wales, who located photographs of battle damage to his ship.After the wreck of the Bismarck was discovered in June 1989, the authors served as technical consultants to Dr. Robert Ballard, who led three trips to the site. Filmmaker and explorer James Cameron contributed a chapter of his comprehensive overview of his deep-sea explorations of Bismarck, illustrated with his team\'s remarkable photographs of the shipwreck.The result of these nearly six decades of research and collaboration is an engrossing and encyclopedic account of the events surrounding one of the most epic naval battles of World War II. Battleship Bismarck has finally resolved some of the major questions such as, Who sank the Bismarck, the British or the Germans? In this latest addition to his acclaimed U.S. warship design history series, Norman Friedman describes the ships and the craft of the U.S. amphibious force, from its inception in the 1920s through World War II to the present. He explains how and why the United States successfully created an entirely new kind of fleet to fight and win such World War II battles as D-Day and the island landings in the Pacific. To an extent not previously documented, his book lays out the differing views and contributions of the U.S. Army, Navy, and Marines as well as the British, and how they affected the development of prewar and wartime amphibious forces. Current and future amphibious forces and tactics are explained, together with their implications for ships and craft, from 40,000-ton amphibious carriers down to tracked amphibious vehicles.As in earlier volumes in the series, this study uses previously unpublished sources to illustrate not only what was actually built but what was planned and never brought into service. For example, the book offers the first comprehensive and fully illustrated account of abortive attempts in the 1960s and beyond to build new fire support ships (LFS). With nearly two hundred photographs and specially commissioned line drawings and extensive appendixes, the work conveniently brings together details of the ships and their service histories found elsewhere only in scattered official references. Henry Petroski traces the origins of the pencil back to ancient Greece and Rome, writes factually and charmingly about its development over the centuries and around the world, and shows what the pencil can teach us about engineering and technology today.
