The record-setting ocean liner will become a massive artificial reef about 22 nautical miles southwest of Destin-Fort Walton Beach.
DESTIN, FL — The SS United States, the record-setting ocean liner that once carried passengers across the Atlantic at unprecedented speeds, is scheduled to be sunk Wednesday off Florida’s Panhandle as part of a $13.5 million project to create what officials say will be the world’s largest artificial reef.
The 990-foot ship is being deployed in the Gulf about 22 nautical miles southwest of Destin-Fort Walton Beach after more than a year of preparation in Mobile, Alabama. Officials moved the sinking ahead by one day because of weather concerns. Deployment operations were expected to begin Wednesday afternoon, with the ship ultimately settling in roughly 180 feet of water. Its upper decks are expected to remain about 60 feet below the surface.
The sinking marks the final chapter for one of the most celebrated American passenger ships of the 20th century. The SS United States entered service in 1952 and set a transatlantic speed record on its maiden voyage, crossing from New York to Europe in about three days and 10 hours. The ship completed more than 800 Atlantic crossings before leaving service in 1969 as commercial air travel increasingly displaced ocean liners on long-distance passenger routes.
Okaloosa County acquired the vessel in 2024 after years of unsuccessful efforts to find a permanent use for it. The ship had spent nearly three decades moored along the Delaware River in Philadelphia, where plans for its restoration as a hotel, museum or renewed passenger vessel repeatedly failed to advance. It departed Philadelphia in February 2025 and was towed to Mobile, where crews began preparing the aging liner for its new role beneath the Gulf.
Preparation involved extensive environmental cleanup and structural work. Fuel and lubricant tanks were emptied and cleaned, hazardous materials were removed, and openings were cut through parts of the ship to allow water and marine life to move through the structure. More than 400 portholes were removed, and the vessel’s large red, white and blue funnels were taken off for preservation. Officials said the ship will be flooded through its existing seawater system rather than sunk with explosives.
The artificial reef project is intended to create new habitat while expanding an already large network of dive sites off Northwest Florida. About 500 artificial reefs are located in nearby waters, according to Okaloosa County. The SS United States site also will be within reach of the USS Oriskany, the former aircraft carrier sunk off Pensacola in 2006 that previously ranked among the world’s largest vessels intentionally placed as an artificial reef.
County officials expect the SS United States to attract recreational divers and anglers while creating habitat for fish and other marine organisms. Researchers from the Woods Hole Oceanographic Institution also plan to study how marine life colonizes the ship, giving scientists an opportunity to monitor the development of a large artificial-reef ecosystem from its earliest stages.
The project preserves portions of the ship’s history above water as well. The SS United States Conservancy has retained the vessel’s funnels, radar mast, stem anchor and other artifacts for a planned land-based museum in the Destin-Fort Walton Beach area. The organization has said the museum will document the liner’s engineering, design and role in American maritime history while providing a companion destination for people who visit the underwater site.
The vessel was built in Virginia by Newport News Shipbuilding and entered service as a symbol of postwar American engineering. More than 3,000 workers helped construct it. At 990 feet long, the ship is longer than the Titanic and was designed for extraordinary speed while also having a potential wartime role transporting troops. Its passenger lists over the years included political leaders, entertainers, royalty and thousands of ordinary travelers crossing between the United States and Europe.
Once the vessel has settled safely on the seafloor and officials complete the required assessments, the site is expected to become accessible to divers. The ship’s size will offer several depth levels, with its highest portions far shallower than the seabed. Officials have not said exactly when recreational access will begin following deployment.
