The Ugly Ships That Won WW2: How America Built a Ship in 4 Days

At one minute past midnight on 8 November 1942, a California shipyard laid the keel of a cargo ship. Four days, fifteen hours and twenty-nine minutes later, the Robert E. Peary slid into San Francisco Bay — built by a man who, two years earlier, had never built a ship in his life. This is the story of the Liberty ships: a plain British tramp-steamer design that Roosevelt called a "dreadful-looking object", and how Henry J. Kaiser, a road and dam builder, turned shipbuilding into an assembly line — prefabricated sections, welding instead of riveting, and tens of thousands of new workers, from Oklahoma farmers to the women the yards called Wendy the Welder. It is also the story of what the speed cost: the ships that cracked in the cold, Constance Tipper's work on brittle steel, and what became of ships designed to last five years. Built from real archive material: Office of War Information photographs of a Liberty ship going up at Bethlehem-Fairfield, Baltimore, in 1943; the U.S. Navy's "Biography of a Liberty Ship" series; United News newsreels and Navy films of launches at Richmond and Baltimore; the photographs of the Kaiser yards and their workers; and the 1947 government report on the ships that cracked.
