14. SS United States
The SS United States, commissioned in 1951, was the world’s fastest ocean liner, setting the transatlantic speed record in 1952. Designed by William Francis Gibbs, she was built to be both a luxury liner and a troop transport if needed. After retiring in 1969, the ship faced various preservation challenges. In 2024, she was sold to Okaloosa County, Florida, with plans to convert her into the world’s largest artificial reef. The SS United States Conservancy continues to advocate for her legacy and preservation (ssusc.org).
