In the coming days, the United States is expected to take its final voyage, on its way to be buried at sea.
It's not the country nearing its end, but a ship that bears its name. The SS United States is a mid-20th century ocean liner that set the speed record for crossing the Atlantic. Now tied up at a Philadelphia pier, its paint peeling and faded after decades of inactivity, it's bound for an ending that is, in reality, a new phase of its life: serving as an artificial reef that attracts divers and marine life in the waters off Florida.
