2,751 Liberty ships were built in the early stages of WWII. Many of them came out of four ship building yards in Richmond, CA. Henry J. Kaiser (builder of the Hoover Dam and the Bay Bridge) took charge of the project. Using new manufacturing techniques these vessels could be produced in about 3 weeks. One of the biggest changes was to replace much of the riveting with welded seams. This new practice of welding decreased labor costs and required fewer skilled workers. This is where the “Rosies” came in. Nick-named “Ugly Ducklings”, the original ships were designed and used to carry supplies to help England in the war effort. They were later used to carry troops as well. The names of the ships were chosen by any group which raised war bonds worth $2 million or more. Most bore the names of deceased people.
