 This fourth wave of expansion involved further shortening the time for building the ships and the further addition of building ways at the existing yards, as well as adding new yards to the emergency program.In early 1942, yards for building Liberty ships were contracted to be built in Vancouver, Washington, to be managed by the Kaiser Corporation, and a yard in Savannah, Georgia, which was to be operated by a new company named Savannah Shipyards, although they had no previous experience with building ships.New yards also contracted to be built at this time, but not for the emergency-type ships, were a third yard in Richmond, also to be managed by the Kaiser Corporation, and a yard in Alameda, California, to be managed by Bethlehem.
