SS United States could begin the final journey of her 74-year story during the second week of November 2026, when the historic liner is expected to leave Mobile under tow for her planned deployment as an artificial reef.
Okaloosa County says the vessel will be positioned in the Gulf of Mexico approximately 22 nautical miles southwest of Destin–Fort Walton Beach, Florida. The operation remains dependent on suitable weather and sea conditions, so no precise departure or sinking date has yet been guaranteed.
The ship will be towed, not sail under her own power
Although widely described as the liner’s final voyage, SS United States has not operated under her own power for decades. Tugboats will move the ship from Mobile to the deployment site.
The SS United States Conservancy says the vessel will probably remain at anchor in the Gulf for around two days while crews carry out final preparations. The ship will then be sunk through controlled flooding using strategically placed openings in the hull. Explosives are not planned.
The objective is for the liner to descend gently and settle upright on the seabed.
Remediation work completed
SS United States has been berthed in Mobile since March 2025 while contractors prepared her for reefing. Destin–Fort Walton Beach officials say the remediation work is complete and that the vessel meets or exceeds the applicable regulatory guidelines for artificial reefs.
The project has also received a ten-year reauthorisation permit from the US Army Corps of Engineers. Preparations have included removing unsuitable materials and creating openings that will eventually allow divers and marine life to move through parts of the wreck.
World’s largest artificial reef
At approximately 990 feet long, SS United States is expected to become the world’s largest artificial reef when measured by vessel length.
The selected location is about 22 nautical miles southwest of Destin–Fort Walton Beach and roughly 32 nautical miles southeast of Pensacola. Earlier project information placed the seabed at approximately 180 feet, with the liner’s upper structure expected to remain substantially closer to the surface.
County officials expect the wreck to create habitat for marine life while attracting divers, anglers and visitors to Florida’s Gulf Coast. The final site and access arrangements will remain subject to official safety guidance after deployment.
A record-breaking Atlantic liner
SS United States entered service in 1952 and immediately captured the Blue Riband for the fastest transatlantic crossing by a passenger liner. On her maiden eastbound voyage she crossed the Atlantic in three days, ten hours and 40 minutes at an average speed of approximately 36 knots.
She carried four US presidents along with prominent figures from entertainment, business and public life. The liner remained in passenger service until 1969 and later spent nearly three decades laid up in Philadelphia.
Historic features preserved ashore
The reef project will not be the only surviving part of the ship’s legacy. The SS United States Conservancy is working towards a land-based museum and visitor experience in Okaloosa County.
Major artefacts and architectural elements have been removed for preservation, including the liner’s distinctive funnels and radar mast. The planned museum is intended to interpret the ship’s design, record-breaking career and place in American maritime history.

Where will the ship be sunk?
The planned site is about 22 nautical miles southwest of Destin–Fort Walton Beach in the Gulf of Mexico.
Will explosives be used?
No explosives are planned. The Conservancy says the ship will be sunk through controlled flooding using openings prepared in the hull.
Has the ship been cleared for reefing?
Officials say remediation has been completed and a ten-year reauthorisation permit has been received from the US Army Corps of Engineers.
Will any part of SS United States be preserved?
Yes. Important artefacts and structural features have been retained for a planned land-based museum and visitor experience.
