Liberty

History: Liberty ships were a class of cargo ship built in the United States during World War II. Though British in concept, the design was adapted by the United States for its simple, low-cost construction. Mass-produced on an unprecedented scale, the Liberty ship came to symbolize U.S. wartime industrial output. The class was developed to meet British orders for transports to replace ships that had been lost. Eighteen American shipyards built 2,710 Liberty ships between 1941 and 1945, easily the largest number of ships ever produced to a single design.

Their production mirrored on a much larger scale the manufacture of the Hog Islander and similar standardized ship types during World War I. The immensity of the effort, the number of ships built, the role of female workers in their construction, and the survival of some far longer than their original five-year design life combine to make them the subject of much continued interest. Only four Liberty ships survive, three are preserved, two as operational museum ships. Another, now landlocked, remains in use as a fish processing plant in Alaska.
