The keel-laying of K-279 took place in Severodvinsk in 1971 , the launch took place in January 1972, and on December 22, 1972 it was finally put into service with the Northern Fleet .
In 1983 the boat had an accident when it collided with an iceberg while submerged in the Arctic Ocean at a depth of 190 meters . The submarine rolled 20 ° and lost its depth control, causing it to descend to about 300 meters, until control could be regained. After the accident, K-279 stayed at sea for two months and only then returned to base. There the damage to the boat became visible: the tower had a large hole. In response to the incident, the Soviet Navy warned all submarine commanders that icebergs could expand to a depth of 200 meters.
K-279 had another accident in October 1986, when it collided, presumably, with the USS Augusta , an American Los Angeles- class submarine, in the turmoil following the accident of K-219 . The bow of the K-279 was pushed in on the starboard side.
In 1992, K-279 was decommissioned and assigned to the reserve fleet. In 1998 the boat was dismantled in its shipyard in Severodvinsk. The reactor section was cut out and taken to Sajda Bay , where it was presumably dumped .
