The Admiral Nakhimov, a nuclear-powered missile cruiser currently being overhauled and modernized, will rejoin the Russian Navy in 2018 with the most advanced weapons systems for its vessel type, the Sevmash shipyard said Thursday, June 23, according to RIA Novosti.

The Kirov-class cruiser, known as the Kalinin until 1992, was commissioned in 1989 and mothballed in 1999. It has since been docked for upgrades at the Sevmash shipyard in the northern Russian city of Severodvinsk, on the White Sea.

Sevmash deputy head Sergei Marichev said in a statement that the Admiral Nakhimov would become the most advanced heavy nuclear-powered missile cruiser in the Russian Navy.
