UPDATED: Russian Navy Cruisers Positioned to Counter U.S., French and Italian Carrier Groups in the Mediterranean

Three Russian guided-missile cruisers have been arrayed across the Black Sea and the Mediterranean Sea to counter three NATO carrier strike groups, causing concern in the Pentagon, a U.S. defense official told USNI News on Tuesday.

As of Monday, the three Slava-class cruisers were operating in and around the Aegean Sea – RTS Moskva (121) in the Black Sea, RFS Varyag (011) south of Italy and RTS Marshal Ustinov (055) off the coast of Syria, near Russia’s naval base in Tartus.

Moskva is based in the Black Sea, while Marshal Ustinov traveled from the Northern Fleet and Varyag from the Pacific Fleet. Ustinov and Varyag entered the Mediterranean from opposite ends earlier this month.
