SS United States, Once the World's Fastest Ocean Liner, Set to Be Sunk Off Destin Wednesday as the World's Largest Artificial Reef

The SS United States, the 990-foot ocean liner that still holds the transatlantic speed record it set in 1952, is scheduled to be sent to the bottom of the Gulf of Mexico on Wednesday afternoon, Nov. 11, about 22 nautical miles southwest of Destin-Fort Walton Beach, where Okaloosa County officials say it will become the world's largest artificial reef.

Deployment is set to begin at 1 p.m. Central time (2 p.m. Eastern), when crews plan to open valves on the ship's original seawater intake pipes and let the Gulf pour in, according to the Pensacola News Journal. The controlled sinking is expected to take about 45 minutes, though the actual time could vary with conditions. The county moved the sinking up one day, from Nov. 12, because forecasters expect heavy winds and unsafe marine conditions later in the week.

The final tow

The liner left Mobile, Alabama, under tow around 9 a.m. Monday, Nov. 9, and reached the deployment site Tuesday, Nov. 10, the News Journal reported. It had been in Mobile since March 2025, when it arrived from Philadelphia, its home since 1996, to be prepared for reefing by Coleen Marine, a Mobile marine contractor.

During that work, contractors removed potentially hazardous materials, cleaned the ship's tanks, sealed compartments considered unsafe for divers and modified parts of the vessel to reduce environmental risks. They also cut square openings, at least 4 feet by 4 feet, into the hull and decks so trapped air can escape as the ship floods, helping it settle upright on the seafloor.

No explosives are planned, according to the SS United States Conservancy. Some of the ship's 128 tanks were filled with water before Wednesday to prepare it for deployment.

Where it will rest

The ship is expected to come to rest in about 180 feet of water, with its upper decks roughly 50 to 60 feet below the surface, a depth the county says will put parts of the wreck within reach of divers of different skill levels. The county released coordinates of 30° 07.148' N, 86° 46.755' W for the site, about 32 nautical miles southeast of Pensacola Pass, and noted the final position could shift slightly once the ship is down.

The U.S. Coast Guard is expected to enforce a safety zone keeping recreational boats at least one nautical mile away. No outside divers are allowed on deployment day. Coast Guard and Florida Fish and Wildlife Conservation Commission crews are expected to stay on scene through Wednesday evening, and if everything goes as planned, recreational divers may visit the wreck starting at dawn Thursday, Nov. 12.

Dive teams from Destin-Fort Walton Beach and the Woods Hole Oceanographic Institution will conduct the first survey of the wreck, and final coordinates will go to the U.S. Army Corps of Engineers.

Where to watch

The deployment will be livestreamed on TheSSUS.com and pnj.com once reefing begins. Public viewing events planned for Wednesday include:

• A free watch party at Seville Quarter in downtown Pensacola, starting at noon, hosted with Visit Pensacola.
• A viewing party on the outdoor screen at AJ's Seafood and Oyster Bar in Destin, starting at noon.
• A sendoff ceremony at 1:30 p.m. at the Destin-Fort Walton Beach Convention Center.

A last-minute legal challenge failed

The sinking is going forward after a federal judge in Pensacola declined to stop it. The SS United States Preservation Foundation sued on Nov. 3, arguing, according to news reports, that the Army Corps of Engineers approved the project without a full environmental impact statement and did not adequately weigh contaminants aboard the ship. U.S. District Judge M. Casey Rodgers denied the group's emergency motion on Nov. 6, the News Journal and other outlets reported. The denial was without prejudice, which leaves the group free to raise the issue again.

From Blue Riband to reef

The United States entered service in July 1952 and on its maiden voyage won the Blue Riband for the fastest Atlantic crossing, averaging 35.59 knots over about 2,942 nautical miles and taking the record from the Queen Mary. It carried more than 1,900 passengers and a crew of more than 1,000 between New York and Europe, with passengers including John F. Kennedy and Marilyn Monroe, according to the News Journal.

Air travel ended its working life. The ship was withdrawn from service in November 1969 and held in reserve for possible Navy troop transport for nine years, then passed through a series of owners whose plans never materialized. Its interior fittings were auctioned in 1984, it was towed to Turkey and Ukraine in the early 1990s for asbestos removal, and it arrived in Philadelphia in 1996. Norwegian Cruise Line bought it in 2003, and the SS United States Conservancy acquired it in 2011, hoping to turn it into a hotel or attraction on the East Coast. When that financing fell through, the Conservancy sold the ship to Okaloosa County in 2024.

What it means for the Emerald Coast

Okaloosa County bought the liner to turn it into a scuba diving destination, betting that a ship 100 feet longer than the Titanic will draw divers to the Emerald Coast the way the USS Oriskany, an aircraft carrier sunk off Pensacola in 2006, has drawn them to Escambia County. The county's online FAQ puts the total project cost at about $13 million, including towing, environmental remediation, the purchase of the ship and funding to help the Conservancy create a land-based museum.

That museum is planned for the Destin-Fort Walton Beach area for people who will never dive the wreck. Contractors preserved historically significant pieces, including the ship's funnels, radar mast and stem anchor, for display there.

The timing also lands just over a month after Hurricane Isaias made landfall in Destin as a Category 2 storm on Oct. 9, as Okaloosa and neighboring counties continue their recovery and look toward the next tourism season.

What's next

If the deployment goes as planned Wednesday, survey teams from Destin-Fort Walton Beach and Woods Hole will dive the wreck first to confirm its position and condition, and recreational divers can begin visiting at dawn Thursday. The timing of the sinking itself could still shift with conditions at sea, and The Florida Press will update this story once the ship is on the bottom.
