SS United States sinks off Florida to become largest artificial reef

Sinking process begins at sea

The vessel was deployed at approximately 2.40pm ET on Wednesday with the sinking starting shortly before 5pm. Water entered the hollowed hull through cut openings to help the ship sink upright to the ocean floor. The structure gradually filled with water before finally resting on the seafloor around 10pm. It will sit at a depth of approximately 180ft with upper decks about 55ft below the surface.

History and ownership changes

The nearly 1,000ft American-made liner was launched in 1952 and set a transatlantic speed record during its maiden voyage. It operated for 17 years carrying thousands of passengers before being retired in 1969. The ship remained docked in Philadelphia until Okaloosa county purchased it for $1m in 2024. This purchase followed rising maintenance costs and a 2021 port fee increase to $1,700 per day.

Marine habitat expectations

Government representatives anticipate that the facility will offer a fresh living space for red snapper, grouper, amberjack, mackerel and tuna. Susan Gibbs, president of the conservancy, stated the site will become a popular diving destination for divers worldwide. Her grandfather designed the ship and she noted his deep personal connection to the vessel. The finale included a live stream showing aerial views of the rusted hulk settling into calm waters.
