The SS United States, the fastest ocean liner ever built and still the holder of the transatlantic speed record, slipped beneath the Gulf of Mexico on Wednesday, 11 November 2026, after crews opened its seawater valves off the Florida coast, and is now the world’s largest artificial reef. The 990-foot ship went down about 22 nautical miles southwest of Destin-Fort Walton Beach, Florida, around 1 p.m. Central time.
The sinking was moved up a day from Thursday, 12 November, because heavy winds were forecast. Flooding began at about 2:40 p.m. Eastern time and, after running behind schedule in the afternoon, the ship slipped beneath the surface; her upper decks now sit roughly 55 to 60 feet below the waterline in about 180 feet of water.

The Fastest Liner Ever Built
She made her maiden voyage in 1952 and set the transatlantic speed record at once, winning the Blue Riband, a record she still holds more than seventy years later. At 990 feet, she is more than 100 feet longer than the RMS Titanic, and in her prime she carried presidents, celebrities and thousands of travellers across the Atlantic.
Her passenger days ended in 1969, and the search for a second act never succeeded. She spent nearly thirty years docked in Philadelphia while preservation groups tried to save her. In February 2025 she was towed out of Philadelphia, and from March 2025 she sat in Mobile, Alabama, being cleaned for the one job left: becoming a reef.
How Do You Sink a 990-Foot Ship on Purpose?
There were no explosives. Crews spent months preparing the hull: seawater-system tanks were removed, large openings were cut into the decks, and more than 400 portholes were taken out.
The ship left Mobile on the morning of Monday, 9 November, with a 100-yard Coast Guard safety zone around her and other vessels kept at least one nautical mile away. Flooding was meant to begin at 10 a.m. on Thursday, 12 November, but the forecast changed and the county pulled everything forward a day. The send-off ceremony planned for 1:30 p.m. on 11 November at the Destin-Fort Walton Beach Convention Center was cancelled, and the sinking began that afternoon, livestreamed for admirers who could not be there. Valves opened at about 2:40 p.m. Eastern time, a fire boat pumped water into the hull, and by about 3:50 p.m. Central time the Pensacola News Journal confirmed two seawater valves were open. By around 4:20 p.m. Eastern time, the operation was running behind schedule.
The Reef Plan: A New Home on the Seabed
She has now taken the title of the world’s largest artificial reef from the aircraft carrier USS Oriskany, sunk off Pensacola in 2006. The two wrecks lie only about 12 to 13 nautical miles apart, giving the Florida Panhandle the two largest artificial reefs on the planet. She also becomes the 21st and largest vessel on the Florida Panhandle Shipwreck Trail.
The wreck will sit in about 180 feet of water, but with her funnels, radar mast and propeller removed, the top of what remains will sit only around 55 to 60 feet below the surface, within reach of recreational divers of all levels. Officials expect tuna, marlin and swordfish to gather around it, and Woods Hole Oceanographic Institution teams will study the water chemistry and track how marine life colonises the wreck.
What Divers Will See Down There
The first divers down will find a ship very different from the gleaming liner of the 1950s photographs. The interiors were stripped, the portholes are gone, and the decks are cut open. What remains is the scale: a 990-foot steel hull, longer than three football fields, lying upright in clear Gulf water with her name still visible on the bow. Swimming along a hull that size, with the top deck just 55 feet down, is the closest most divers will ever come to the great ocean liners, which is why the wreck is already being called a Mount Everest-type destination for scuba divers.

Frequently Asked Questions
When was the SS United States sunk?
Sinking operations began on Wednesday, 11 November 2026, a day earlier than planned, because heavy winds were forecast for Thursday, 12 November. Valves opened at about 2:40 p.m. Eastern time, and the ship slipped beneath the surface around 1 p.m. Central time.
Where exactly is the SS United States reef?
About 22 nautical miles southwest of Destin-Fort Walton Beach, Florida, at 30°07.148′ N, 86°46.755′ W. She rests in about 180 feet of water, her top deck 55 to 60 feet below the surface.
Why was the ship sunk instead of preserved?
No museum or hotel plan succeeded in decades of trying, and she spent nearly thirty years docked in Philadelphia. Okaloosa County bought her in October 2024 for $10.1 million to create a reef. A preservation lawsuit was denied on 6 November 2026.
How deep will divers have to go?
The top deck sits 55 to 60 feet below the surface, within reach of recreational divers of all levels. The seabed is about 180 feet down.
Were explosives used to sink the ship?
No, only controlled flooding. Crews removed seawater-system tanks, cut large deck openings and took out more than 400 portholes so water could flow in evenly and the ship would settle upright.
Can I dive the wreck now?
The wreck was expected to open to divers the day after the sinking, from dawn on 12 November, once dive teams surveyed its resting position. Check for the official announcement before planning a trip.
