The Gen. Hoyt S. Vandenberg ship last used by the U.S. Air Force to track missiles and spacecraft has been sunk in the Florida Keys, creating the world’s second largest manmade reef.

The 523-foot, 17,000-ton WWII ship was sunk seven miles off Key West on Wednesday.

The ship sank in less than two minutes after demolition experts triggered a series of explosives that lined the both sides of the ship.

Acquiring the ship first built as a cargo ship in World War II and removing tons of toxins and other dangerous items has cost $8.6 million, Florida officials however expect the sunken scenery to generate $8 million annually in tourism related revenue.
