This book details the Liberty ships and the Emergency Shipbuilding Program during World War II. For the first time, comprehensive information is provided about the builders, the namesakes, and the operators under one cover. Included is a list of all 2,710 Liberty ships delivered by U.S. shipyards, giving each ship's namesake and detailed descriptions of the companies that built the ships and the steamship companies that operated them during the war. This book also details the formation of two shipyards in South Portland, Maine, the Todd-Bath Iron Shipbuilding Co. and the South Portland Shipbuilding Corp. South Portland's shady operations were investigated by the U.S. Congress and resulted in the merger of both companies into the New England Shipbuilding Corporation in April 1943. Also featured is the Jeremiah O'Brien. Built by New England Ship in 1943 and one of only two operational Liberty ships left in the world, its service history and crew information are given along with its postwar restoration and return to Normandy in 1994.
