SS United States sunk off Florida to become world's largest artificial reef

The retired ocean liner SS United States was deliberately sunk in the Gulf of Mexico off Destin, Florida, on Wednesday. The operation was intended to turn the vessel into an artificial reef, described as the world's largest.

The ship was once the fastest ocean liner in the world. It is nearly 1,000 feet long. The South China Morning Post (SCMP) gives 302 metres (990 feet), and the BBC says it is longer than the Titanic. It carried passengers across the Atlantic from 1952 until it was retired in 1969. It then spent years docked in Philadelphia. A Florida county government bought it. A land-based museum about its history is planned. The non-profit SS United States Conservancy had tried unsuccessfully to preserve the ship.

How the sinking unfolded

According to The Guardian, the ship was deployed at about 2:40pm ET. It began sinking shortly before 5pm and reached the bottom around 10pm. Reuters and SCMP described it as heading for the sea floor. The Guardian reported that the ship had been hollowed out and that openings were cut into its hull to help it sink upright. The BBC said the sinking was planned as a precision operation without explosives. SCMP said the ship had been stripped of its two smokestacks and that the sinking was shown on a live stream.

According to The Guardian, the ship will rest at about 180 feet, with its upper decks about 55 feet below the surface. The site is expected to become a popular diving destination.

Background

The Guardian identified the buyer as Okaloosa County, which paid $1m in 2024. It reported that in 2021 port authorities raised the daily dockage fee to $1,700, which the Conservancy could no longer afford. According to the BBC, the ship spent nearly 30 years in Philadelphia and was moved to Alabama last year for cleaning and remediation, then to Destin on Monday. The BBC also reported that earlier plans for a museum or floating hotel failed. It listed passengers including Harry Truman, John Kennedy, Marlon Brando and Walt Disney.

The reports reviewed by Vocemundi do not include official confirmation of the ship's final position or whether it landed upright. They do not describe the project's total cost, or who carried out the sinking.

What is disputed

The Guardian says the ship was launched in 1952. SCMP's account implies 1951. The Guardian says William Francis Gibbs designed the ship. The BBC says he helped design it.

What each side says

Officials expect the reef to provide habitat for red snapper, grouper, amberjack, mackerel and tuna, according to The Guardian.

Susan Gibbs, the Conservancy's president, whose grandfather was involved in designing the ship, welcomed the outcome. The Guardian quoted her as saying: "She’s being reefed and will remain intact and will become a vibrant and dynamic marine habitat, so that, combined with the land-based museum and visitor experience, will honor her history in a deeply moving way." According to the BBC, she told CBS News: "[The ship] has always been this unabashedly American symbol that brings so many people together".

Analysis

The sinking ends a long effort to keep the SS United States afloat as a museum or hotel. It shows how hard and costly it can be to preserve very large historic vessels. Supporters of the reef see a new role for the ship as marine habitat and a diving site. Others may still see a loss for maritime heritage. Several questions remain open: whether the ship settled as planned, how much the project cost overall, and when the planned land-based museum will open. Official updates on the reef's condition and visitor numbers could help show whether the project meets its stated goals.
