(FILES) This file picture fated July 23, 1995 shows Rusian navy sailors pulling the rope to help a Russian nuclear submarine of the Project 971 Shchuka-B type, or Akula-class (Shark) by NATO classification dock at the military port of Murmansk, in the Kola peninsula, northern Russia. At least 20 people were killed and 21 hurt in an accident on a Russian nuclear submarine in the Sea of Japan, the navy said on November 9, 2008, the worst such incident since the Kursk disaster. A source in the Amur shipyard administration named the submarine as the K-152 Nerpa, a nuclear-powered submarine of the Project 971 Shchuka-B type, or Akula-class by NATO classification, the RIA Novosti news agency reported.
