The USS Oriskany is an Essex-Class aircraft carrier that has been sunk and repurposed by the US Navy as an artificial reef now stationed off the Florida coast in the Gulf since 2006. It is the largest artificial reef and the most successful with at least 38 fish species calling her home. Be sure to watch the video of the divers at the ship.
