Liberty ship

A military cargo ship built in large series during the Second World War: 2,751 of them were built in the United States between 1941 and 1945, in 70 days on average (and only 7 days, 14 hours and 29 minutes for the Robert E. Peary). It was a simple functional ship, rapidly constructed from prefabricated, welded components. Standard Liberty ships measured 134.5 m long and could transport 10,000 tonnes of cargo.
