World’s Famous Fastest Ocean Liner is Getting a New Life 180 Feet Beneath the Sea
Once the fastest ocean liner in the world, the SS United States carried some of the biggest names of the 20th century across the Atlantic. Now, more than 70 years after her record-breaking debut, the nearly 1,000-foot ship is preparing for a very different voyage: a one-way trip to the bottom of the sea.
Florida officials plan to sink the historic vessel in the Gulf, where she’ll become the world’s largest artificial reef and a new destination for scuba divers. The operation is now scheduled for Wednesday, Nov. 11, after concerns about approaching high winds prompted a last-minute change.
The ship will be submerged approximately 22 nautical miles southwest of Destin-Fort Walton Beach. Her massive steel structure will be used to attract and provide habitat for marine life over time. In addition, divers will eventually be able to explore portions of the vessel that once raced between America and Europe.
Okaloosa County purchased the ship in 2024 and originally scheduled its deployment for Nov. 12. However, in a Nov. 9 announcement on Instagram, the county confirmed that the operation had been rescheduled to Nov. 11 because of predicted “heavy winds and unsafe weather conditions” the following day. The public sendoff ceremony was also canceled.

The SS United States entered service in 1952 and wasted no time reshaping maritime history in its own speedy image. During her maiden voyage, she crossed the Atlantic in three days, 10 hours, and 40 minutes, setting a speed record for an ocean liner that remains unbeaten.
The ship’s passenger lists included Hollywood royalty such as Marilyn Monroe, Marlon Brando, Judy Garland, Cary Grant, and Elizabeth Taylor. Walt Disney also traveled aboard, as did John F. Kennedy and Jacqueline Kennedy, Princess Grace of Monaco, and Salvador Dalí. According to the SS United States Conservancy, even Leonardo da Vinci’s enigmatic, smiling Mona Lisa made the crossing in 1963 while traveling to exhibitions in the United States. The ship had another, less glamorous purpose built into its design: during the Cold War, it could have been converted to transport approximately 14,000 troops in the event of a military emergency.
Commercial air travel eventually changed that business, and the ship was retired in 1969. Various proposals to restore or repurpose her failed over the following decades. She spent nearly 30 years docked in Philadelphia before Florida’s Okaloosa County acquired the aging liner in 2024, as the possibility of scrapping her loomed.
The ship arrived in Mobile, Alabama, in March 2025, where crews began preparing it for its new life underwater. The work included draining and cleaning 128 tanks that once held fuel and lubricants, along with removing materials that could pose environmental risks once the vessel was submerged. The process also involved inspections throughout all 12 decks, according to Destin-Fort Walton Beach‘s official project updates.
Several historic features have been saved. The SS United States Conservancy, which spent years working to preserve the ship, has secured her enormous funnels, radar mast, and other artifacts for a planned museum in the Destin-Fort Walton Beach area.
A New Destination for Marine Life and Scuba Divers
Engineers plan to lower the ocean liner to the seafloor through controlled flooding rather than explosives. If the operation proceeds as intended, the vessel will settle in a neat, upright position within approximately 180 feet of water, and its upper levels will be accessible to appropriately trained recreational divers.
The ship’s hull and surrounding structure are expected to provide hard surfaces where marine organisms can easily attach and grow. Over time, fish and other marine life may take shelter around the wreck, adding to the region’s extensive, diverse network of artificial reefs.
The SS United States will surpass the USS Oriskany, an aircraft carrier sunk off Pensacola in 2006, as the world’s largest artificial reef by vessel length. Florida officials also expect the attraction to draw divers and support nearby tourism businesses. According to Visit Florida, an official date for recreational diving access had not yet been announced.
Deployment operations are scheduled to begin at 1 p.m. Central time on Nov. 11, weather permitting. A livestream will be available through The SS United States Project, and Okaloosa County is hosting a public viewing party beginning at noon at AJ’s Seafood and Oyster Bar in Destin, where the sinking will be shown on a large outdoor screen. Hundreds of boats may also gather near the deployment site, and the county has urged spectators on the water to follow instructions from safety vessels.
The ship’s story above the water is not completely done with this sinking. Its preserved artifacts are destined for a museum developed in partnership with the SS United States Conservancy, where visitors will be able to learn about the liner’s engineering, famous passengers, and record-setting voyages before exploring its final resting place beneath the Gulf.
