The naval war fleet took over the new ship on December 19, 1989 and on February 28, 1990 TK-20 was incorporated into the newly established 18th division of the 1st Flotilla of the Northern Fleet in Nerpichya Bay near Sapadnaja Liza . A deterrent patrol in the Northern Sea followed . TK-20 survived the collapse of the Soviet Union without any particular incident.

In November 1996, TK-20 patrolled the North Pole and fired an RSM-52 missile from there. On July 24, 1997 TK-20 took part in the naval parade in Severomorsk . Sporadic patrols followed in the Barents Sea . In 2000 it was baptized with the name Severstal , and the steel company of the same name took over the sponsorship of the ship. In June 2001 a television team was allowed to take part in a patrol trip of the TK-20 Severstal for the first time. The documentary was broadcast by ZDF under the title On an invisible mission - en route with the largest submarine in the world . During this voyage, an RSM-50 missile was shot down. In July 2001, the repair work began at Sevmasch in Severodvinsk, which was completed in December 2002.

During 2003, TK-20 launched their last 10 RSM-52s into space, where they self-destructed.

The submarine is currently assigned to the reserve and is based in Severodvinsk. Like the TK-17 Arkhangelsk , it is to be decommissioned and scrapped by 2020.
