In a unique campaign involving serial nuclear submarines without any modifications.
Missile boat K-116 (project 675) under the command of captain II rank Vyacheslav Vinogradova joined the Navy in late 1965. It was intended to destroy ships of enemy missiles P-6, as well as for attacks on large onshore facilities strategic cruise missiles P-5M. The second nuclear submarine K-133 (project 627А) captain II rank of the Lion carpenter had torpedo armament. She was three years older submarine.
Before the Soviet submariners have been an ambitious task to overcome the anti-submarine secretly the borders of NATO and the United States in the Atlantic and the Pacific, and strengthen the Pacific fleet and two nuclear submarines. Therefore, directly supervised the operation commander of the 1 St submarine flotilla of the Northern fleet, rear Admiral Anatoly Sorokin. Its headquarters is located on K-116.
For the success of the command of the Navy paved route through lesser known areas of the World ocean. Although he considered three possible transition route. The first involves the transition around South America through the Drake passage, and the second around Africa through the Malacca and Singapore, and the third around Africa and Australia by the Singapore Strait. Admiral of the fleet Sergei Gorshkov chose the first option - through the Drake passage.
The submarine was moving under water and only occasionally rose to periscope depth to determine the location.
As recalled were on K-116 nuclear scientist and doctor of technical Sciences Anatoly Chekurov, the sub once surfaced at the entrance to the Drake passage. It was the most difficult section of the route is 1300 miles. At the tip of South America observed the treacherous currents and there are numerous icebergs, so the divers had to share navigation content.
Through the "graveyard of ships" - the Drake passage - subs "spent" tanker "Danube" and expeditionary vessel "Gavriil Sarychev". Seven days it took Soviet submarines to leave the boundary of the icebergs.
The connection between the submarines under water was maintained by using hydroacoustic equipment. Sometimes K-116 and K-133 at a certain time went to trick anti-submarine ships of the United States, and then met at the rendezvous point.
Successfully overcame the Soviet submariners and psychological testing. According to the RVIA member, historian Alexander Konovalov, to relieve irritability, fatigue and apathy were conducted shipboard feasts, celebrated the birthdays of members of the crew. By the way, under water 24 March 1966 celebrated the 45th anniversary of the commander of the detachment - rear Admiral Anatoly Sorokin.
Sailors To a-133 during the entire expedition were the handwritten journal "Chronicle of the campaign, or 25,000 miles under water", which contains poems, essays and drawings submariners. Now the log is stored in the Central naval Museum in St. Petersburg.
March 26, 1966, in 4 hours 26 minutes off the coast of Kamchatka submarine was met by Soviet destroyers. The transition took 52 days. After the transition K-116 and K-133 was enrolled in the division of Kamchatka submarine flotilla. The appearance of two new submarines in Krasheninnikov Bay was an unpleasant surprise to the US intelligence and NATO.
According to the results of an unprecedented campaign of six officers-submariners, including Admiral Sorokin and commanders of submarines, was awarded the title of Hero of the Soviet Union. The other crew members presented the awards and medals.
