Florida to dump 990-foot ship in Gulf of Mexico to create world’s largest artificial reef. It will create a new marine habitat

The historic SS United States is preparing for one final voyage to the floor of the Gulf of Mexico. Florida’s Okaloosa County plans to sink the 990-foot ocean liner in November 2026, transforming the former transatlantic speed record-holder into what officials hope will become the world’s largest artificial reef. The project, which has a reported budget of $10.1 million, aims to create new marine habitat and attract divers to Florida’s Gulf Coast. But the plan has also faced questions over potential environmental risks associated with the ship’s materials.

From Record-Breaking Ocean Liner To Artificial Reef

Launched in 1952, the SS United States became famous for its speed on transatlantic crossings. It carried presidents, dignitaries and Hollywood stars before retiring from passenger service in 1969, as air travel changed the shipping industry. After spending decades docked in Philadelphia, the vessel left the city in February 2025 and was towed to Mobile, Alabama, for environmental remediation and preparation. According to CBS News, the ship is expected to be deployed around 22 nautical miles southwest of Destin-Fort Walton Beach during the second week of November. The timing remains weather-dependent.

How The $10.1 Million Project Is Expected To Work

Okaloosa County purchased the ship in 2024 after it faced the possibility of being scrapped. The county’s plan includes towing and preparing the vessel, sinking it at an approved location and supporting a land-based museum dedicated to its history. Before deployment, contractors have been removing hazardous materials and preparing the hull. The county says the ship will provide a structure where marine organisms can settle and fish can find shelter.


Artificial reefs can create habitat in areas where suitable structures are limited. Florida already has a network of artificial reefs that supports marine life and recreational diving. The SS United States would join the nearby USS Oriskany, a former aircraft carrier sunk off Pensacola in 2006.

Why Environmental Concerns Remain

The proposal has attracted criticism from preservation advocates and some environmental scientists, who have raised concerns about potentially hazardous coatings on the ship, including zinc chromate. In February 2026, PhillyVoice reported that University of Florida biogeochemist Todd Osborne warned that chemicals from the coating could pose risks if they entered the marine environment. Okaloosa County, meanwhile, has maintained that the project is being prepared in accordance with applicable environmental requirements.

The dispute highlights an important distinction: an artificial reef can provide habitat, but that benefit depends on a vessel being cleaned and prepared appropriately. The environmental debate is therefore not simply about whether shipwrecks attract marine life, but whether this particular ship can be deployed without unacceptable risks.

A Historic Ship Will Also Be Preserved On Land

Not every part of the SS United States will disappear beneath the water. Its funnels, radar mast, anchor and other components have been retained for a planned land-based museum near future diving-tour departure points. For Florida, the project offers the prospect of combining marine habitat, tourism and maritime history. Its long-term success, however, will depend on the final approvals, careful deployment and evidence that the new reef benefits marine life without causing lasting environmental harm.
