From ocean legend to undersea reef: Why has the SS United States been sunk?

The historic SS United States ocean liner has taken its final trip, this time to the bottom of the ocean, as it becomes part of an artificial underwater reef . The nearly 1,000-foot (302m)-long vessel, the fastest ocean liner in the world, was sunk on Wednesday after its hull was hollowed out to ensure it remains on the ocean floor, in a process also known as scuttling.

Over five hours, the ship gradually filled with water and, in its final moments, tilted to its side and sank to the bottom of the Gulf of Mexico off the coast of Destin, Florida. The vessel will now feature as part of the world’s largest artificial reef, which is expected to become a popular diving destination.

Built between 1950 and 1951, the ship was larger than the Titanic, which was 882 feet nine inches (269.1 meters) long. The SS United States was known for its speed, strength and luxury.
