The famous ship SS United States will be sunk off the coast of Florida to become the world's largest artificial underwater reef, APA reports.
The vessel, once the world's fastest passenger ship and longer than the Titanic, remained in the port of Philadelphia for nearly 30 years.
It will become a habitat for marine life and a tourist attraction for divers.
The ship, which operated from 1952 to 1969, carried former US presidents Harry Truman, Dwight Eisenhower, John F. Kennedy and Bill Clinton, as well as celebrities such as Marlon Brando, Coco Chanel and Walt Disney.
After plans to convert the ship into a museum or floating hotel failed to materialize, it was purchased by authorities in Florida's Okaloosa County.
Following cleaning and restoration work, the ship was transported from Alabama to waters off the coast of Destin, Florida. It is planned to be sunk in a special operation without the use of explosives.
A museum showcasing the ship's history will be established on land.
