This is a fascinating video. It shows how the US Navy destroys its old ships, one scrap of metal at a time, recycling every component to make new parts. The ship is the USS Savannah, a Wichita-class tanker almost as long as two American football fields and ten floors high.
This thing was huge and heavy: 659 feet (201 meters) long, 96 feet (29 meters) tall. It used to displace 40,743 tons when full and, apart from all that fuel, it carried two CH-46 Sea Knight helicopters.
She was the fifth Savannah in the history of the US Navy, launching on April 23, 1970. The ship, which ended its life in 1995, served as a replenishment oiler for the 6th Fleet in the Mediterranean until 1972, when she left to Vietnam to serve during the war. At the end of 1973, she returned to the Mediterranean until June 1974, when she returned to Norfolk, Virginia. [National Geographic Channel and Wikipedia]
