SS United States Sunk Off Florida to Become World's Largest Artificial Reef
One of the most recognizable passenger ships in American maritime history has finally gone beneath the waves.
The SS United States, once the world's fastest ocean liner ever built, was deliberately scuttled off the coast of Florida on Wednesday, November 11, after a long series of delays regarding its fate. The vessel will now become the world's largest artificial reef.
The 990-foot (302 m) ship was sent down approximately 25 miles (40 km) southwest of Destin, Florida, in an planned scuttling that took significantly longer than anticipated. The process began around 1 p.m. local time, but the vessel remained partially above the surface for several hours before finally listing and disappearing below the water around 9 p.m. Viewers were able to watch the scuttling by livestream around the world.
The sinking marks the culmination of a $13.5 million project orchestrated by Okaloosa County, Florida, which purchased the retired ocean liner in 2024. From the outset, the county announced plans to use the vessel as an artificial reef and underwater attraction for recreational divers and anglers. Although its final resting position isn't yet confirmed, it it's expected to settle upright in approximately 180 feet (55 m) of water, with its upper deck roughly 60 feet (18 m) below the surface.
The scuttling finally occurred after more than a year of preparation at a shipyard in Mobile, Alabama, where contractors removed all of the ship's components aside from the hull and interior framework. The preparation also included removing the remaining fuel in its tanks, as well as lubricants, wiring, and glass that could pose an environmental hazard. Other preparations included removing more than 400 portholes, while large openings were cut into the hull and decks to facilitate flooding and create access for marine life. The ship's 128 fuel and lubricant tanks were emptied, cleaned, and then filled with seawater to ensure an even descent, although it appears the system did not work entirely as planned. Notably, the ship's original 65-foot smokestacks were removed during the preparation process and are expected to be used as part of a land-based museum exhibit. Other signature pieces of the vessel were also preserved for future museum exhibits.
To get the ship to go under, the demolition team did not use explosives. Instead, seawater was gradually introduced through various openings in the vessel, allowing it to gradually fill in a controlled process.
The project will now add the SS United States to more than 500 existing artificial reef sites in the Destin-Fort Walton Beach area. County officials expect the wreck to attract recreational divers and fishing enthusiasts. It will also provide additional habitat for marine species including tuna, marlin, and swordfish.
Despite its new location, the SS United States has a remarkable history from its operational yeas. The vessel entered service in 1952 as one of the most technologically advanced passenger ships of its time.
Built by Newport News Shipbuilding in Virginia, the ship measures 990 feet (302 m) in length, making it 108 feet longer than the Titanic. More than 3,000 workers were part of its construction between 1950 and 1951.

But its most significant achievement came during its maiden transatlantic voyage in July 1952, when it broke the speed record for a passenger liner crossing the Atlantic. With an average speed of approximately 35.6 knots (41 mph), the ship completed the eastbound journey in just three days, 10 hours and 40 minutes. The feat surpassed the previous record held by Britain's RMS Queen Mary. The achievement earned the SS United States the Blue Riband, a famous unofficial reward given to the fastest passenger liner crossing the Atlantic. Although it lost the eastbound speed record in 1990 to the Hoverspeed Great Britain, a high-speed catamaran, the SS United States still holds the Blue Riband for the westbound record for a conventional passenger liner.
During its 17 years of commercial service, the vessel also completed more than 800 Atlantic crossings and transported thousands of passengers, including U.S. presidents, British royalty, and Hollywood celebrities. Notable passengers included Harry Truman, Dwight Eisenhower, John F. Kennedy, Elizabeth Taylor, and Grace Kelly.
The downturn in her service was brought on by the growth of commercial aviation eventually, which made transatlantic ocean liner services increasingly difficult to remain commercially viable. The SS United States was withdrawn from service in 1969.
Following its retirement, the vessel spent decades moving between proposed redevelopment projects and various ownership arrangements. Plans to transform the ship into a floating hotel, entertainment venue, or museum never materialized. In 1996, it arrived in Philadelphia, where it remained docked along the Delaware River for nearly three decades.
The SS United States Conservancy, a nonprofit organization established to preserve the vessel, worked for years to find the vessel a new home where her heritage could be preserved. However, the mounting maintenance costs, deteriorating condition, and increasing dockage fees forced it to seek out a new future for the ship. A dispute with the ship's pier operator in Philadelphia eventually resulted in an eviction, forcing the Conservancy to find move the vessel to a new location.
In 2024, Okaloosa County purchased the ship directly from the Conservancy for approximately $1 million USD, along with a proposal to convert it into an artificial reef off Florida's Gulf Coast. The decision was immediately met with opposition. Preservation advocates, maritime heritage organizations, and government officials argued that the vessel should be saved as a museum or waterfront attraction rather than scuttled
Several alternatives were explored, including relocating the vessel to New York. Legal challenges followed. Those efforts ultimately failed, and a federal judge rejected an attempt to halt the Okaloosa Country project.
After the county took ownership, the vessel was towed 1,800 miles from Philadelphia to Mobile, Alabama, in February 2025. The journey south attracted considerable public attention, with large crowds gathering along waterways to watch the historic liner pass by. In doing so, public awareness about the ship's plight only increased.
Despite the public hubub, the SS United States will now join another artificial reef in the region: the USS Oriskany, a 911-foot aircraft carrier deliberately sunk off Pensacola, Florida, in 2006. The Oriskany previously held the record as the world's largest artificial reef. The two wrecks are located close enough that divers may be able to visit both sites during the same day.
The Woods Hole Oceanographic Institution has announced plans to work with other research organizations to monitor the wreck and document how marine organisms colonize the vessel over time.
