Florida Sinks SS United States to Form Reef

Live Poll

Do you support using old ships as artificial reefs in your area?

Florida sank the SS United States in the Gulf of Mexico to create an artificial reef, which is described as the world's largest. The ship was built in 1952 for transatlantic passenger service and was previously the fastest passenger liner to cross the Atlantic.

Why it matters

The reef is expected to draw scuba divers and boost tourism in the Florida Panhandle, a benefit projected for Wind, Pelican Reef and the state's dive industry. The project turns a retired ocean liner into marine habitat and a destination for divers.

The reef's top sits roughly 100 feet below the surface, off Pensacola Beach in Okaloosa County. The number of U.S. commercial scuba divers exceeds 3 million, the market the project is expected to attract.

The players

SS United States

The SS United States was a transatlantic ocean liner built in 1952 that held the record as the fastest passenger liner to cross the Atlantic before being repurposed as an artificial reef.

The details

Before sinking, the ship's hull was cleaned of hazardous materials through environmental and regulatory processes. The vessel was towed to the site and scuttled according to a planned sequence.

1952: The ship was built for transatlantic passenger service.
Late 2027: The reef is expected to be finished, with a fully developed ecosystem projected about 10 years later.

Seasonal Patterns

Scuttled retired vessels have long been used in U.S. coastal waters as artificial reefs that gradually support marine life. The SS United States project extends this practice to a former transatlantic liner on a far larger scale.

Divers interested in the site should plan for depths around 100 feet at the reef's top. Trips to the Pensacola Beach area may become a practical option as the reef develops toward its projected completion in late 2027.

The takeaway

Artificial reefs built from retired ships can create lasting marine habitat, though full ecosystem development is projected to take roughly a decade after completion.
