Shrouded by smoke from detonated explosives, a former World War Two US troop ship was sunk off the Florida Keys on Wednesday to become a massive artificial reef that authorities hope can revive the local economy and environment. After the controlled explosive charges were set off, it took only three minutes for the rust-streaked 523-foot (159 meter), 17,000-ton gray bulk of the General Hoyt S. Vandenberg to slip below the surface. It sank 140 feet to settle on the sandy bottom, seven miles off Key West on the southern tip of Florida. The sinking turned the wartime relic, which also was used by the US Air Force to track Soviet missile launches during the Cold War and still carried its big tracking dish, into one of the world's biggest intentionally sunk artificial reefs. Local officials and businessmen are hoping that in its new resting place the Vandenberg will provide a boon to both the marine environment and the local economy, which has felt the squeeze of the global economic recession. They expected the wreck would be an immediate underwater draw for divers, while at the same time attracting fish, corals and other sea creatures and so relieving the pressure on Key West's natural reefs caused by diving, boating and fishing. Before it was sunk, the Vandenberg was cleansed of contaminants, such as asbestos, wiring, paint and other potentially toxic substances and debris.
