The USS Arizona was sunk by the Japanese in their attack on Pearl Harbor in 1941. The ship took nearly 1,200 sailors to their deaths. The Arizona later became a national memorial.

As Erin Brummet reports on this edition of Dateline, the submerged ship is in danger of breaking apart and leaking more than a million gallons of oil which still remain on the rusting hulk.

Erin spoke with metallurgist John Makinson about the efforts to catalogue the Arizona and prevent an ecological disaster.
