The retired U.S.S. Oriskany is now host to fish and divers. Click here to see the 32,000-ton hulk sink
Five hundred pounds of plastic explosive sent this 32,000-ton aircraft carrier to the bottom of the Gulf of Mexico in May, forming the largest intentional man-made reef in history and marking the inauguration of a Navy program to turn old ships into coral reefs. To meet EPA standards for sea disposal, the 888-foot carrier was stripped of oil, paint and asbestos, at a cost of $8 million. It worked: The scuttle didn´t even leave a slick on the surface. The hull of the craft now rests at 212 feet, too deep for casual scuba divers, though the higher superstructure should be fair game.
