Shipbuilding. "Liberty" ships. Workers at a prefabricating plant turn out steel parts for a large Eastern shipyard building units of Uncle Sam's "Liberty Fleet." Here they operate a giant shear. This plant was originally used to produce freight cars, and the shears are part of the plant's original equipment. All parts are prefabricated in this huge Eastern plant which formerly turned out freight cars. The completed sections are then carried six miles to the ways on flatcars.
