The Fastest Ocean Liner Ever Built Took 5 Hours to Sink. Now It's a Reef Off Destin.

DESTIN, Fla., Nov. 13, 2026 — The SS United States still holds the record as the fastest ocean liner ever built. Her last trip was a slow one.

Okaloosa County had planned to start sinking the 990-foot ship around 1 p.m. Wednesday and expected it to take up to three hours, AL.com reported. By 5 p.m., with night falling over the Gulf, nothing visible had happened. A boat full of reporters gave up and headed back to shore around 6.

The holdup was in the plumbing. County spokesman Nick Tomecek told WEAR-TV that crews first had to fill some very large tanks inside the ship, and didn't begin opening more than a dozen valves to let the sea in until about 4 p.m. Once the water came, air trapped inside slowed things down again. The liner finally went under around 9 p.m., about five hours after the flooding began.

No explosives were used. The county always sinks its reefs by flooding them, Tomecek said, and this ship happened to come with valves that were part of how she operated in her heyday.

"The fastest passenger liner in the world crossed the Atlantic Ocean in less than four days. On Wednesday, it sank in five hours," NPR put it. Launched in 1951 and longer than the Titanic, she once carried four presidents, the Mona Lisa and a long list of movie stars before spending decades rusting and facing the scrap heap. In the end she tilted onto her side and slipped under quickly.

She landed right side up, which was the whole point. A remote-operated vehicle and side-scan sonar showed the ship sitting upright about 180 feet down, nearly on the exact coordinates crews were aiming for, roughly 22 nautical miles southwest of Destin-Fort Walton Beach, the county said.

That makes her what Okaloosa County calls the world's largest artificial reef, built for fish and for divers. The top deck sits about 60 feet below the surface, and rough weather pushed back Thursday's first official inspection dive, but recreational divers were given the all clear late Thursday once the safety zone was lifted, the Pensacola News Journal reported.

Not everything went down with her. The smokestacks and propeller were removed beforehand, and the SS United States Conservancy plans a museum in Okaloosa County to tell the ship's story on dry land.
