SS United States to Become World's Largest Artificial Reef

October 28, 2026

The SS United States, once the fastest passenger liner in the world, is scheduled to be scuttled in the Gulf of Mexico in November 2026, creating what will be the world's largest artificial reef.[1]

Built in 1951 and designed by naval architect William Francis Gibbs, the 302m (990ft) vessel earned the Blue Riband for the fastest transatlantic crossing on her maiden voyage in July 1952, completing the journey in 3 days, 10 hours, and 40 minutes, beating the previous record held by RMS Queen Mary by over 10 hours.[1][2]

She served as both a luxury passenger vessel and a potential military transport, with design features allowing conversion to carry a 14'400-man army division if needed. The rise of commercial jet travel ended her ocean-going career in 1969, and she spent decades changing hands, slowly deteriorating at a mooring in Philadelphia.[2]

In 2011, the SS United States Conservancy purchased the ship with plans to redevelop it as a waterfront attraction, but a rent dispute led to an eviction order in September 2024. Okaloosa County, Florida stepped in, purchasing the ship for approximately $1 million with the intent to sink it as an artificial reef.[1]

The ship departed Philadelphia in February 2025 and arrived in Mobile, Alabama for extensive preparation. All 128 fuel and lubricant tanks have been emptied and certified safe, over 200 samples collected for hazardous material assessment, and the US Army Corps of Engineers has authorised the required permits. The sinking is planned for approximately 22 nautical miles southwest of Destin-Fort Walton Beach, with the exact date dependent on weather.[1]

Artificial reefs provide critical habitat for marine life and attract divers, boosting local tourism economies. The SS United States, at nearly 300 metres, will surpass the USS Oriskany (an aircraft carrier sunk in 2006 at 277 metres) as the largest vessel intentionally reefed.[2]

It is a fitting end for a ship that once held the world's speed record, to find a second life beneath the waves.
