The SS United States, the fastest ocean liner ever built, slipped beneath the waves off the Florida coast on Wednesday night, becoming the world’s largest artificial reef. The SS United States sinking came a day earlier than planned, after officials moved the operation up because of forecast heavy winds.
The liner sank around 10 p.m. Eastern time on Wednesday, November 11, more than five hours after officials said deployment had begun, according to the Destin-Fort Walton Beach live stream and the Pensacola News Journal. Okaloosa County, Florida, had moved the sinking up a day, from Thursday, because of forecast heavy winds and unsafe conditions. Deployment operations began at 1 p.m. Central time on Wednesday at a site about 22 nautical miles southwest of Destin and Fort Walton Beach, at 30 degrees 07.148 minutes North, 86 degrees 46.755 minutes West.
A Slow Descent Into the Gulf
Crews opened the last valves and left the ship around 5:45 p.m., and for hours afterward the red paint on the bottom of its hull still showed above the waterline. The ship should rest in about 180 feet of water, with its top deck about 60 feet below the surface. The project cost $13.5 million. The wreck opens to divers the next day, according to WALA-TV in Mobile. Destin-Fort Walton Beach, the county’s tourism department, streamed the deployment live on YouTube.
The 990-foot liner was built to be converted into a troopship in wartime, and designer William Francis Gibbs divided its hull into 20 watertight compartments, designed to keep it afloat with as many as five of them flooded, according to National Geographic. The deployment used controlled flooding rather than explosives, according to the SS United States Conservancy. The ship entered service in 1952 and established a transatlantic speed record on her maiden voyage, becoming one of the most celebrated ocean liners of the twentieth century.
Final Voyage Ends After 74 Years
The ship began its final journey from Mobile, Alabama, on Monday morning, November 9, after being docked at Modern American Recycling and Repair Services in Mobile since March 2025, where crews spent months preparing it to become an artificial reef. It was withdrawn from service in 1969 and moored in Norfolk, Virginia. The SS United States Conservancy, a non-profit, bought the vessel in 2011, and Okaloosa County bought the retired liner in 2024.
A last-minute attempt to save the ship failed: the SS United States Preservation Foundation went to federal court in Pensacola on November 3, and a judge declined to block the sinking. The Conservancy has preserved the ship’s funnels and is developing an SS United States museum in Okaloosa County.
