The historic ocean liner the SS United States will have to wait a bit longer to embark on its final voyage. Often called "America's flagship," the SS United States measures at nearly 1,000 feet long and is the longest and largest ocean liner ever built in America.

The SS United States will soon rest at the bottom of the Gulf of Mexico off Destin, Florida, creating the world's largest artificial reef. It will be prepped in Mobile, Alabama before it sinks. That could take a year.

The planned move of the decommissioned former cruise liner SS United States from Philadelphia to the Gulf of Mexico has been delayed due to logistics issues, its owner said this week.
