An ocean liner is about to take its final, most improbable voyage: straight to the bottom of the Gulf of Mexico.
Okaloosa County officials announced this week that the historic SS United States is slated to be sunk off the Florida coast during the second week of November, weather permitting.
The ship that raced across the Atlantic will soon stand completely still, offering ocean life a vast new home. Settling into the seabed roughly 22 nautical miles (41 kilometers) southwest of Destin, the legendary ship is set to become the “world’s largest artificial reef”: a underwater metropolis for marine life.
“This is an exciting move forward to create a one-of-a-kind resource for the environment and for our tourism industry,” county officials wrote in a news release as AP reported.
County leaders expect the new attraction to draw scuba enthusiasts and charter fleets from around the world, funneling millions of dollars each year into local dive shops, charter fishing outfits, and hotels.
Transatlantic record-breaker
It is a striking second act for a vessel born of speed and mid-century American ambition.
Launched in 1952, the nearly 990-foot ocean liner shattered the transatlantic speed record on its maiden voyage, cutting across the Atlantic in just three days, ten hours, and forty minutes. This feat shattered the Queen Mary’s previous record by roughly 10 hours.
The vessel earned the coveted Blue Riband for the fastest transatlantic passenger liner crossing, a title Atlas Obscura reports the ship still holds today.
Reports said building the SS United States cost between $70 million and $79.4 million. The U.S. government funded $50 million of the total sum to help support the ship’s construction.
But decades of changing travel habits left the ship docked, rusting, and facing an uncertain future. Retired in 1969 after 17 years at sea, the vessel passed through several owners while steadily deteriorating over the decades.
A rent dispute with the owner of its Philadelphia pier eventually forced the SS United States Conservancy to sell the vessel. Okaloosa County purchased the ship for $1 million, leading to its February 19, 2025 departure from Philadelphia under tow to Mobile, Alabama.
Preservationists fought for years to restore the grand liner, but astronomical maintenance costs ultimately sank those ambitions.
Marine haven
Now, its fate lies on the ocean floor.
Environmental groups and scientists raised concerns that the vessel’s zinc chromate primer could contaminate the Gulf, though Okaloosa County confirmed the project satisfies EPA regulations. A federal lawsuit attempting to stop the sinking was dismissed in August 2025. County officials described the initiative as an exciting advancement for local tourism and environmental growth.
Measuring 990 feet, the ocean liner will surpass the 888-foot USS Oriskany, which held the record for the largest artificial reef since its sinking off Pensacola in 2006.
Supporters expect the rusting hull to turn into a thriving reef ecosystem for divers and local marine life. Joining a network of more than 500 existing artificial reefs in the region, the SS United States is expected to become the crown jewel of Gulf Coast diving.
