Historic Ocean Liner SS United States Set to Become World's Largest Artificial Reef Off Florida

The SS United States, the fastest ocean liner ever built and once a symbol of American maritime power, is scheduled to be towed into the Gulf of Mexico and sunk on Thursday, Nov. 12, in what officials in Okaloosa County, Florida, are billing as the creation of the world's largest artificial reef. The deployment, weather permitting, is set to begin at 10 a.m. local time about 22 nautical miles southwest of Destin-Fort Walton Beach, at coordinates the county's tourism office has published as 30° 07.148′ N, 86° 46.755′ W.

The 990-foot vessel has spent the past two years moving toward this end point. It was towed out of Philadelphia in February 2025 after nearly three decades docked at Pier 82, then spent months in Mobile, Alabama, where crews emptied, cleaned and inspected all 128 of its fuel and lubricant tanks and stripped its interior of asbestos and other hazardous materials in preparation for the sinking. The U.S. Coast Guard has established a temporary moving safety zone around the ship and its tow vessels, in effect from Nov. 6 through Nov. 16, covering all navigable waters within 100 yards of the ship as it transits the Mobile River Channel, Mobile Bay and the Gulf en route to the Florida site.

A $10 million project years in the making

Okaloosa County took title to the ship in October 2024 after buying it for $10 million from the SS United States Conservancy, the nonprofit that had owned and struggled for years to preserve it. County officials have said the roughly $10 million reefing project is funded entirely through local tourism-development tax revenue and private contributions, including a $500,000 donation from Coastal Conservation Association Florida, described as the group's largest gift in four decades, with no property-tax dollars involved.

The ship's history helped drive both the preservation effort and the eventual decision to sink it. Launched in 1952, the SS United States set the transatlantic speed record on its maiden voyage, a mark it still holds for a passenger liner, and later carried four U.S. presidents — Harry Truman, Dwight Eisenhower, John F. Kennedy and Bill Clinton — along with passengers including Walt Disney, Judy Garland, Marilyn Monroe and John Wayne. It was taken out of commercial service in 1969 and sat largely idle for decades, most recently moored in South Philadelphia, as successive efforts to restore or repurpose it fell through.

Okaloosa County officials, who are hosting a public sendoff ceremony on Nov. 11 at the Destin-Fort Walton Beach Convention Center and a viewing event the next morning at a Destin restaurant, have framed the sinking as a new chapter rather than an ending. Board Chairman Trey Goodwin called the planned deployment, according to PhillyVoice, a milestone for the region.

"A historic day for Destin-Fort Walton Beach and for a ship with such a historic story," Goodwin said, adding that the vessel's story "will continue to be told" through visits to the wreck and a planned land-based museum.

A legal fight that fell short

The plan to sink the ship was contested in federal court by the New York Coalition to Save the SS United States, a preservation group that sued Okaloosa County in the U.S. District Court for the Northern District of Florida in Pensacola, arguing the county's reefing plan would permanently erase a piece of American maritime history. U.S. District Judge M. Casey Rodgers denied the county's initial motion to dismiss the case in April 2025 but later ruled, in August, that the coalition lacked legal standing to block the project, finding that its claimed injury was what the judge described as self-inflicted and not grounded in a legally protected interest. The ruling cleared the county's path to proceed with the sinking after months of uncertainty over the ship's fate.

Opponents have also raised environmental concerns, questioning whether submerging the ship could introduce contaminants into Gulf waters despite the remediation work completed in Mobile. County officials and the SS United States Conservancy, which continues to operate as a historical and educational organization even after transferring ownership of the ship, have said the reefing project followed state and federal environmental review requirements before receiving final approval to proceed.

What happens next

Once sunk, the ship is expected to rest at a depth of roughly 180 feet, with its uppermost structure coming to within about 60 feet of the surface, making it accessible to recreational and technical divers. County officials have said it would surpass the decommissioned aircraft carrier USS Oriskany, sunk off Pensacola in 2006, as the largest vessel ever deployed as an artificial reef. The Florida Fish and Wildlife Conservation Commission is expected to monitor the site to track how quickly fish and coral begin colonizing the wreck, a process officials hope will also benefit local dive tourism.

Okaloosa County, through its tourism bureau, has said a livestream of the deployment will be made available on the morning of the sinking, and the county has posted notices of the public sendoff events on its own government site. Anyone on the water near the site will be required to stay clear of the vessel under the Coast Guard's safety zone order, with authorized vessels and safety boats directing traffic during the operation. A county notice posted in October confirmed the schedule for the sendoff ceremony ahead of the ship's final voyage.

The timeline still carries a caveat officials have repeated throughout the process: the date depends on weather and sea conditions in the Gulf, and the county has said it reserves the right to adjust the schedule if conditions do not cooperate. Should the Nov. 12 deployment proceed as planned, it would close out a saga that has spanned Philadelphia court dockets, a congressionally watched preservation campaign and, ultimately, a federal judge's ruling, ending with one of the 20th century's most storied ocean liners settling onto the Gulf floor as a new reef nearly 75 years after it first set to sea.
