The SS United States is getting towed down the East Coast on its way to the Florida panhandle, where it will be sunk and turned into an artificial reef.

The SS United States is set to make one final journey before becoming the world's largest artificial reef. On Thursday, the Okaloosa County Tourism Development Department and Destin-Fort Walton Beach announced that the SS United States is slated to begin moving operations on Friday, Feb. 14.

After months of delays, the historic SS United States ocean liner finally moved out of Philadelphia on a new voyage as it prepares to become the world's largest artificial reef off the Florida coast.

The ship will eventually be laid to rest at the bottom of the ocean about 20 miles off the coast of Florida. It will become the world's largest artificial reef.

A storied ocean liner that offered passengers regal elegance while setting trans-Atlantic speed records for decades began its final journey this week at a much more measured pace.
