As the United States entered World war I in 1917, the government created the Emergency Fleet Corporation to construct a fleet of ships. The Emergency Fleet Corporation hired the American International Shipbuilding Corporation to build and operate the largest shipyard in Hog Island (Philadelphia). Shipbuilding industries receive help from World War I. The reason for constructing massive shipbuilding industries of the ships was to win the war in seas, especially against the Germans, who were far more advance in building U-boats.
