Sevatopol is redundant and outdated

Putin spent some $500m US$ equivalent on upgrading naval facilities at Novorossiysk so that an alternative to Sebastopol would be ready when the lease expired in 2017. It was readied in 2013.

According to Izvestiya , “those objects are meant for large-size warships having deep draft. That will make possible to start redeployment of Black Sea Fleet from Crimea to Novorossiysk. The fleet’s flagship, Guards missile cruiser Moskva will arrive in the new base first”.
