context_page_description: Liberty ships were a class of cargo ship built in the United States during World War II. Though British in concept, the design was adopted 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 the manufacture of "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.
context_section_description: More than 2,400 Liberty ships survived the war. Of these, 835 made up the postwar cargo fleet. Greek entrepreneurs bought 526 ships and Italians bought 98. Shipping magnates including John Fredriksen, John Theodoracopoulos, Aristotle Onassis, Stavros Niarchos, Stavros George Livanos, the Goulandris brothers, and the Andreadis, Tsavliris, Achille Lauro, Grimaldi and Bottiglieri families were known to have started their fleets by buying Liberty ships.  Andrea Corrado, the dominant Italian shipping magnate at the time, and leader of the Italian shipping delegation, rebuilt his fleet under the programme. Weyerhaeuser operated a fleet of six Liberty Ships (which were later extensively refurbished and modernized) carrying lumber, newsprint, and general cargo for years after the end of the war.
  The term "Liberty-size cargo" for 10,000 long tons (10,200 t) may still be used in the shipping business.
  Some Liberty ships were lost after the war to naval mines that were inadequately cleared. Pierre Gibault was scrapped after hitting a mine in a previously cleared area off the Greek island of Kythira in June 1945, and the same month saw Colin P. Kelly Jnr take mortal damage from a mine hit off the Belgian port of Ostend. In August 1945, William J. Palmer was carrying horses from New York to Trieste when she rolled over and sank 15 minutes after hitting a mine a few miles from destination. All crew members, and six horses were saved. Nathaniel Bacon ran into a minefield off Civitavecchia, Italy in December 1945, caught fire, was beached, and broke in two; the larger section was welded onto another Liberty half hull to make a new ship 30 feet longer, named Boccadasse.
  As late as December 1947, Robert Dale Owen, renamed Kalliopi and sailing under the Greek flag, broke in three and sank in the northern Adriatic Sea after hitting a mine. Other Liberty ships lost postwar to mines include John Woolman, Calvin Coolidge, Cyrus Adler, and Lord Delaware.
  In 1953, the Commodity Credit Corporation (CCC), began storing surplus grain in Liberty ships located in the Hudson River, James River, Olympia, and Astoria National Defense Reserve Fleet's. In 1955, 22 ships in the Suisun Bay Reserve Fleet were withdrawn to be loaded with grain and were then transferred to the Olympia Fleet. In 1956, four ships were withdrawn from the Wilmington Fleet and transferred, loaded with grain, to the Hudson River Fleet.
  Between 1955 and 1959, 16 former Liberty ships were repurchased by the United States Navy and converted to the Guardian-class radar picket ships for the Atlantic and Pacific Barrier.
  In the 1960s, three Liberty ships and two Victory ships were reactivated and converted to technical research ships with the hull classification symbol AGTR (auxiliary, technical research) and used to gather electronic intelligence and for radar picket duties by the United States Navy. The Liberty ships SS Samuel R. Aitken became USS Oxford, SS Robert W. Hart became USS Georgetown, SS J. Howland Gardner became USS Jamestown with the Victory ships being SS Iran Victory which became USS Belmont and SS Simmons Victory becoming USS Liberty. All of these ships were decommissioned and struck from the Naval Vessel Register in 1969 and 1970.
  USS Liberty was a Belmont-class technical research ship (electronic spy ship) that was attacked by Israel Defense Forces during the 1967 Six-Day War. She was built and served in World War II as SS Simmons Victory, as a Victory cargo ship.
  From 1946 to 1963 the Pacific Ready Reserve Fleet – Columbia River Group, retained as many as 500 ships.
  In 1946 Liberty ships were mothballed in the Hudson River Reserve Fleet near Tarrytown, New York. At its peak in 1965 189 hulls were stored there.  The last two were sold for scrap to Spain in 1971 and the reserve permanently shut down.
  Only two operational Liberty ships, SS John W. Brown and SS Jeremiah O'Brien, remain. John W. Brown has had a long career as a school ship and many internal modifications, while Jeremiah O'Brien remains largely in her original condition. Both are museum ships that still put
