The SS United States: America’s Biggest and Fastest Ocean Liner The SS United States was the largest passenger ship ever built in the United States and a flagship example of mid century American industrial strength. Completed in 1952 at Newport News Shipbuilding, the vessel measured about 990 feet in length and displaced more than 53,000 tons. Its design used unprecedented quantities of aluminum in bulkheads, deckhouses, and framing to reduce structural weight and increase power to weight efficiency. Construction required more than 2,000 workers, extensive precision welding, and strict quality controls because the ship’s engines were adapted from classified naval propulsion systems. These turbines produced more than 240,000 shaft horsepower, giving the vessel unmatched acceleration and sustained high speed capability. On its maiden voyage the SS United States seized the Blue Riband, covering the westbound Atlantic in just over three days with an average speed above 35 knots. No passenger liner has surpassed this performance. The ship carried more than 1,900 passengers and nearly 1,000 crew and was built to convert rapidly into a troop carrier able to transport more than 14,000 personnel. The dual purpose design, compartment layout, and material choices, including fire resistant furnishings and reinforced decks were intended for heavy military loads. The liner operated from 1952 to 1969 before withdrawal due to rising operating costs and competition from jet aircraft. Since retirement it has remained laid up yet structurally sound, supported by preservation campaigns that emphasize its engineering significance. The SS United States remains the largest and fastest ocean liner ever produced in America and a benchmark in high performance civilian shipbuilding. #History #USHistory #America #USA #Shipbuilding
