A Florida county is in talks to acquire a storied but aging ocean liner in a proposed deal that could create the largest artificial reef in the world.

But the plan hit a snag Tuesday, after local officials in coastal Okaloosa County in the Florida panhandle postponed a vote on the plan to buy and purposefully sink the SS United States.

The largest passenger ship ever built in the U.S., the SS United States shattered a record for the fastest trans-Atlantic crossing by a passenger liner on its maiden voyage in 1952, The Associated Press reported from aboard the ship.
