Russia appears to be moving additional air and naval assets into Syria and the Eastern Mediterranean, giving its military commanders more options in the theatre.
A Project 636.3 'Kilo'-class diesel-electric submarine was seen transiting the Bosphorus form the Black Sea into the Mediterranean on 14 March. While Russian subs are unmarked, Turkish ship spotters identified it as Krasnodar .
A day later, the Russian Ministry of Defence reported that Stary Oskol , another Project 636.3 serving with the Black Sea Fleet's 4th Independent Submarine Brigade, was preparing to put to sea.
