Documents on the wreck of the Soviet submarine K-129, which nearly for 30 year were kept top secret by US Intelligent Service, were given to the Pacific Navy Museum in Vladivostok, Russia.
      
      The documents includes a video record of the funeral ceremony of remains of six members of the crew of the Soviet submarine K-129, made in the USA in 1974, and also a folder with copies of printed documents about the search for the missing submarine and lifting it from the sea with the help of the ship Glomar Explorer.
      
      K-129 (Golf-II) was not nuclear powered, though it carried nuclear weaponry - three R-13 ballistic missiles as well as two nuclear-tipped torpedoes. It also carried cryptographic gear for transmitting and receiving encoded, secure communication.
      
      In 1968 K-129 left the Kamchatka Bay of Krasheninnikov and headed to the Pacific Ocean to Hawaii Islands. On March 8 the submarine didn't answer a control session of radio communications.
      
      The search operation continued for two months, 30 ships, vessels and submarines of the Pacific Navy took part in it, aviation was lifted in air, but the search brought no result. The reason of wreck of the submarine is still unknown.
      
      There are three main versions - flooding of the submarine through the RDP shaft during charging of batteries because of technical malfunction of a valve and collapse to the forbidden depth, explosion of hydrogen during charging of storage batteries because of malfunction of evaporation systems, which caused destruction of the body, and finally, collision with another submarine.
      
      K-129 was found by the Americans, who organized its salvaging in summer of 1974. During the salvaging the submarine broke into two parts, but it was possible to deliver some of its compartments to one of the bases of the US Navy. During investigation six bodies of Soviet submariners were found.
