The SS United States, the record-setting ocean liner launched in the early 1950s, was prepared for a controlled sinking Wednesday off Florida’s Gulf Coast to begin a new role as an artificial reef and diving destination.
Crews planned to flood the 990-foot vessel at a site about 22 nautical miles southwest of Destin-Fort Walton Beach. The operation was expected to take roughly 45 minutes once valves connected to the ship’s original seawater intake system were opened. Some of the liner’s 128 tanks had already been filled as part of the preparations.
Okaloosa County moved the deployment forward from November 12 because forecasts called for stronger winds and unsafe marine conditions. County officials said changing the date would reduce unnecessary risk during the carefully managed operation.
The ship reached the offshore site under tow from Mobile, Alabama, after environmental remediation and engineering work required to convert it into a reef. The Coast Guard established a safety zone intended to keep recreational boats at least one nautical mile away, while state and federal security vessels were expected to remain around the site after the sinking.
Dive teams associated with Destin-Fort Walton Beach and the Woods Hole Oceanographic Institution planned an initial survey after the vessel settled. Their work would establish its exact resting position and provide coordinates to the U.S. Army Corps of Engineers. Recreational access was expected to begin as early as dawn Thursday if the deployment proceeded safely.
Okaloosa County says the ship will be the world’s largest artificial reef. The project is also intended to create a major attraction for divers, giving the retired liner an economic and ecological role after decades of failed restoration efforts.
The SS United States entered service in 1952 and set a transatlantic speed record on its maiden voyage, a record it still holds. It was retired in 1969 as jet travel displaced ocean liners on international routes. The county purchased the vessel in 2024 for the reef project.
Not everyone supported that outcome. The SS United States Preservation Foundation filed a federal lawsuit seeking to stop the tow and sinking, but a judge denied its request on November 6.
The controlled deployment closes the ship’s long period in limbo while preserving it in a radically different form. Instead of returning to passenger service or becoming a shore-based museum, the liner will serve as a submerged habitat and a destination accessible principally to divers.
