The Moskva missile cruiser was modernized about 4 years ago. While the hull is old, the armaments and radars are not.
On 3 December 2009, Moskva was laid up for a month at floating dock PD-30 for a scheduled interim overhaul which comprised replacement of cooling and other machinery, reclamation work at bottom and outboard fittings, propulsion shafts and screws, clearing and painting of bottom and above-water parts of the ship’s hull.
