The Russian nuclear submarine Kursk, which sank on Aug. 12, 2000, is shown during a naval parade in the Barents Sea on Russia's Navy Day, in Vidyayevo, June 30, 2000. A desperate effort to reach the sunken submarine ended Monday, Aug. 21, 2000 when divers said none of the sailors was alive more than a week after a catastrophic explosion left them inside a crumpled wreck on the bottom of the sea.
