Return of the Big ‘Uns
By 
Admiral Nakhimov, one of Russia’s ancient Kirov class battlecruisers, appears near a return to service:
The Admiral Nakhimov served in the Soviet Northern Fleet until the dissolution of the USSR. Her tempo of operations was radically reduced after the collapse, and she was placed in full reserve in 1999. In 2006, as Russia’s financial situation recovered, the Russian Navy decided to restore the Admiral Nakhimov to service.
She joined her sister ship, the Pyotr Velikiy, as the centerpieces of the fleet. The modernization was supposed to be complete by 2012.
However, the modernization was not complete in 2012; it was not complete in 2022. Stops and starts along the way reflected uncertainty about whether it made any sense to rehabilitate an aging battlecruiser, along with hiccups in funding and in the shipyard workforce.
From time to time, the refurbishment seemed like more of a joke than a serious project, although the fact that the Pyotr Velikiy remained in service confirmed Russian interest in continuing to operate a nuclear battlecruiser.
The modernization process of the Admiral Nakhimov was intended to bring her up to modern standards in terms of offensive and defensive capabilities, as well as electronic systems. Her on-deck missile launchers were to be replaced by a whopping 174 vertical launch system cells, 80 of which would carry anti-surface missiles, and 96 reserved for anti-aircraft missiles.
Her radars and electronic warfare systems were also to be modernized. We do not yet have concrete information regarding how many of these intended refits were completed.
