After Pearl Harbor, the United States went into overdrive in producing military weapons, ships, and planes. Defense companies increased production while commercial companies were transformed to help the war effort. American shipyards began manufacturing vessels at a rapid pace. By the time fighting was done, the number of active ships in the U.S. military had grown from 790 to 6,768. (Also see every carrier-based aircraft the United States used during WWII .)
24/7 Wall St. reviewed warship production figures from Military Factory , an online repository of military equipment data, to determine the most mass-produced American military ships used during the Second World War. We exclusively considered ship classes that served in WWII and had a minimum production of nine units during the class’s lifespan. The classes are ranked by their total production count, including those built before or after the war. Additional information regarding the type, notable ships, crew, and year of service also originated from the Military Factory. Ships within the same class often exhibited distinct crew complements.

World War II was a unique time for the American economy in terms of the war effort (bonds, material drives, rationing) and the mass production of weapons and vehicles by some of its biggest manufacturers, many of which are still around today. The biggest American shipbuilders were Newport News Shipbuilding & Drydock, New York Shipbuilding Corporation, and the Bethlehem Shipbuilding Corporation. Newport News Shipbuilding & Drydock is currently owned by Huntington Ingalls Industries, one of the top current shipbuilders of the United States Navy.
