This new book tells the story of the Ocean class of standard cargo ships, their design, building and careers, and the author places them firmly in the context of the battle of the Atlantic which was raging at the time of the first launchings. While their achievements alone would merit an important place in histories of the war at sea, the impact of the oceans stretched far beyond the direct contribution of the ships themselves. The yards where they were built also served as models for a series of new American shipyards and the oceans' blueprints were used as the basis for the American Liberty ship. This comprehensive new history, based on extensive archival research and lavishly illustrated with contemporary photographs, restores the Oceans to their rightful place in history. The ships' design antecedents are explained, and their ordering, financing and construction analyzed in full. Wartime operations are covered in depth, by theater and with full details of war losses and other casualties. The book concludes with an assessment of their subsequent peacetime careers and a comparison to other war-built designs. This is a model history of a highly significant class of ship.
