From fastest passenger ship to world's largest artificial reef: Historic US ocean liner sinks off Florida

The SS United States, once the fastest passenger ship, was sunk in the Gulf of Mexico. This project aimed to create the world’s largest artificial reef for marine life. The vessel's sinking took longer than anticipated due to safety measures during the operation. Now resting about 180 feet underwater, the ship will become a diving destination. Previous failed commercial efforts to repurpose the ship prompted its preservation as a reef.
