Before the opening of the shipyard, Swan Island was the location of the Swan Island Airport. The Port of Portland leased the airport to the U.S. federal government in March 1942.[5][6] The completed Swan Island yard began production in July 1942 with eight shipways.[7] The Swan Island Shipyard was one of four shipyards in the United States specifically designed to produce T2 tankers.[3]: 94–95 It produced 147 tankers over the course of the war, all of them of the T2-SE-A1 design.[3]: 129–43
