Kirov is the lead ship of the of nuclear-powered guided missile cruisers. Originally built for the Soviet Navy and passed onto the succeeding Russian Navy, she and her three sister ships are the largest and heaviest surface combatant warships (i.e. not an aircraft carrier or amphibious assault ship) built by them. The Soviet classification of the ship-type is "heavy nuclear-powered guided missile cruiser" (), nonetheless Kirovs size and weapons complement have earned her the unofficial designation of a battlecruiser throughout much of the world, as her size and displacement is similar to a typical World War I battleship. The appearance of the Kirov class was a significant factor in the U.S. Navy recommissioning the . She was named after a Project 26 cruiser (named after Sergey Kirov, a Bolshevik hero). History She was laid down on 27 March 1974, at the Baltiysky Naval Shipyard in Leningrad, launched on 26 December 1977, and commissioned on 30 December 1980, part of Soviet Northern Fleet. When she appeared for the first time in 1981, NATO observers called her BALCOM I (Baltic Combatant I). Her first major deployment was in 1984 where she undertook a voyage to the Mediterranean Sea.

Repairs were never carried out, due to lack of funds and the changing political situation in the Soviet Union. She may have been cannibalized as a spare-parts cache for the other ships in her class. For political reasons, Kirov was renamed Admiral Ushakov after the 18th-century admiral Fyodor Fyodorovich Ushakov in 1992, but subsequent photos suggest that it has since reverted to its original name. An overhaul was started in 1999, but the ship was written off in 2001 and was slated to be dismantled in 2003. In June 2004, the name Admiral Ushakov was transferred to the . In September 2004, it was revealed that the Severodvinsk-based Design Bureau Onega had been tasked with developing the dismantlement project for the cruiser, currently moored at the Severodvinsk Zvezdochka plant. According to the Zvezdochka plant, dismantlement of the former Admiral Ushakov would cost $40 million. This plan was halted when the Russian Navy planned to bring her back to service. In 2010, the Russian Navy again announced new plans for an overhaul of the cruiser. At the time,
