Navy as an instrument of big strategy
by Ilya Kramnik
Moscow (Voice of Russia) Aug 31, 2012
"Joint Russian-US-Norwegian Northern Eagle-2012 exercises have ended in the Barents Sea. "
"At present, the Russian Navy is far behind that of the USSR in the number of ships with good fighting capacity."
"The current number of ships is sufficient for performing anti-piracy duty in the Gulf of Aden and for periodical appearance in important parts of the world ocean to demonstrate the Russian flag but keeping ships in areas vitally important for Russia's interests on a permanent basis is beyond Russia's potential so far.
Nevertheless, the currently made efforts allow to solve many problems."

That, and the exercise going on in Russia, might explain the departure of the russian ships from that syrian harbour, if they departed at all.
