Admiral Nakhimov
The vessels of the "Kirov" class are the world's largest cruisers, and for this reason they are generally referred to as battlecruisers. Two "Kirov" battlecruisers are currently in service, the RFS "Admiral Nakhimov" and RFS "Pyotr Velikiy". In the last 6 years, the "Pyotr Velikiy" (Peter the Great) has participated in numerous military exercises, with President Vladimir Putin being on board during the last one. The older "Admiral Nakhimov" was repaired and returned to service in 2005; the ship is currently undergoing upgrade renovations and should return to active service in the late 2010s.
