Launching Liberty by Doug Most
6.5 out of 10From 1941 to 1945, nearly 3,000 Liberty cargo ships were manufactured in American shipyards. They were built in 18 ports on the east, west, and Gulf coasts. The whole program was an impressive feat of industrial mobilization. It was often the case that women trained to become skilled welders and hard laborers. The aim was to iteratively improve efficiency with each ship produced. Though increased production speed sometimes resulted in more defects, the overall effectiveness of Liberty ships played an extremely important role in winning WWII.
