The SS United States, an ocean liner larger than the Titanic, may one day sail again. Crystal Cruises luxury travel company announced plans to overhaul the ship at a cost of at least $700 million.

Before it can be turned into a state-of-the-art commercial vessel, the SS United States must undergo a nine-month feasibility study. Take a look at the behemoth as it is now, before any major changes.
