How the SS United States was sunk on purpose, and why it ran into the night

On Wednesday 11 November 2026 the SS United States, an ocean liner 990 feet long, was sunk on purpose in the Gulf of Mexico, about 22 nautical miles southwest of Destin-Fort Walton Beach, Florida, to become an artificial reef. She was 108 feet longer than the Titanic. The organizers had said it could finish in as quickly as an hour. It ran into the night. Here is what was done and what was said, with our own 3D illustration.

What was done

The ship is 990 feet long (AP). The Titanic was 108 feet shorter, so about 882 feet. Okaloosa County, Florida, helped organize the sinking, to make an artificial reef.

No explosives. A spokesperson for Okaloosa County said, as AP reported, that federal environmental and explosives rules prevent the county and its contractor from using explosives to scuttle the ship. Instead, workers cut 10-foot by 10-foot holes in the decks, and more than 400 portholes were removed. The same spokesperson said the ship has pipes that pulled seawater into tanks for cooling its boilers, and that those tanks were removed so that water would flood the hull.

Before the sinking the organizers also removed the funnels. The county says the radar mast and the propeller were removed too, all kept for a planned museum (Destin-Fort Walton Beach).

What happened on the day

The county had planned to start at 1 pm. The official deployment began around 1:40 pm Central (6abc live blog). AP: organizers had predicted the sinking "could finish in as quickly as an hour".

After dark she was still above water. The 6abc live blog says she remained above water at 9:30 pm Eastern, which is about 8:30 pm in Florida. In that same entry a county spokesperson is quoted: "She was designed to be unsinkable, and that fact has definitely given our crews some challenges today."

That is a remark about the day, said that evening. It is not a line from the ship's design record: the design papers we read, the Conservancy's and the National Park Service's, do not call her unsinkable.

Around 9 pm Central, AP reports, the ship "leaned on one side and then quickly submerged". The times in this note are approximate, from the live blogs and AP.

On Thursday morning a county spokesperson confirmed that sonar imaging and a remotely operated underwater vehicle had verified the ship landed upright, despite briefly shifting to one side during its descent (Pensacola News Journal, 12 November).

What is not known

Why it ran so long. The county spokesperson said, as AP reported, that it "took longer than we thought" and gave filling tanks so that she would rest evenly on the sea floor as part of the reason. We did not find a fuller account. AP says she leaned to "one side"; we do not rely on which side. This note is current to 12 November 2026.

Our take

"As quickly as an hour" was the organizers' best case, and the day went to the slow case. When we plan anything that depends on a physical process, we write down the best case as a best case, plan the schedule on the slow one, and say which assumption each number needs. A best case that reads as the plan is how a long day becomes a surprise.

About the film

Our own 3D illustration, not footage. The ship is drawn without her funnels and radar mast, which were removed for a museum; she is not drawn exactly as she sank, and the lean at the end is drawn to one side. The cutaway is a schematic: deck lines, a gap in every deck for the holes, water rising. It carries no labels or numbers. The clock in the corner is in Central time and approximate. The "unsinkable" remark is the county spokesperson's, said that evening (6abc), not a design record. The voice is synthetic. Music: "Sci-Fi Score" by Arulo (Mixkit).

Transcript

This ship is longer than the Titanic.

Last night, it sank too.

On purpose.

No explosives were allowed.

So the crew cut holes in the decks, and let the sea in.

Organizers said it could take as little as an hour.

After dark, she was still above water.

A county spokesperson said: "She was designed to be unsinkable, and that fact has definitely given our crews some challenges today."

Then she leaned to one side, and was gone.
