The Cargo Ship America Built in Four Days
A German U-boat could sink a cargo ship in minutes. So America decided to build them faster than the enemy could ever destroy them. This is the story of the Liberty ship: a plain, welded, mass-produced freighter that rolled off the slipways by the thousands, the shipyards of Henry Kaiser that built one in days instead of months, and the workforce of welders who kept the lifeline across the Atlantic open. In this full-length documentary we go deep on the Liberty ship and how America out-built the U-boats. We cover Liberty ship, Henry Kaiser, welded hulls, Battle of the Atlantic, merchant marine, and mass production ā the people, the decisions, and the consequences, told with original narration and rare archival footage and photographs. If you love detailed, story-driven World War history, this one is for you. ā± CHAPTERS 00:00 The math of the Atlantic: sinkings vs. building 04:00 Why the old way of building ships was too slow 10:00 Welding instead of riveting: the revolution 16:00 Henry Kaiser and the four-day ship 22:30 Rosie the welder and the new shipyard workforce 29:00 How 2,700 ugly ships out-built the U-boats 33:30 The legacy of mass-produced shipping š IN THIS DOCUMENTARY ā¢ Why welded hulls changed shipbuilding forever ā¢ The Kaiser shipyards and prefabrication ā¢ How production beat the U-boat campaign ā¢ The women and first-time workers who built the fleet š ABOUT THE CHANNEL World War 2 History brings you deep, story-driven documentaries about the weapons, machines, battles and people of the World Wars.
