About this site
The USNS General Hoyt S. Vandenberg is a decommissioned military ship, 522 feet (159 metres) long, sunk off Key West in 2009 as an artificial reef. It is the second-largest artificial reef in the world.
The wreck rests in about 140 feet (42.7 metres) of water and is rated technical. There is plenty to explore, from the ship's radar dishes to its interior spaces. Water temperatures run from 75°F (24°C) in winter to 85°F (29°C) in summer, and divers have reported goliath grouper, barracuda, snapper, parrotfish, moray eels and angelfish around the wreck.
