The US sank the SS United States to create the world’s largest reef

After several hours of maneuvering, the historic ocean liner SS United States was scuttled in a controlled operation off the coast of Florida. 

The iconic vessel now begins a new chapter beneath the sea, where it will become the largest artificial reef on the planet. 

 The sinking of the 302-meter-long naval colossus, acquired in 2024 by Okaloosa County, Florida, brought an end to decades of neglect in Philadelphia, a protracted legal dispute over mooring rights, and the failure of various attempts to fund its restoration.

Following extensive preparation work in Mobile, Alabama, which began in March 2025, the legendary vessel was readied for its final submersion in the Gulf of Mexico, an environmental and tourism project that also includes the opening of a museum on land to preserve its historical legacy.

 The practice of creating reefs from decommissioned ships is well-known along the Florida coast: the submerged hulls are quickly colonized by marine life and become popular spots for divers. The SS United States stands out significantly from other such sites due to its sheer size, its dimensions are comparable to those of the largest passenger liners from the mid-20th century.
