Two Russian guided-missile cruisers from Russia’s North and Pacific fleets met off the coast of Syria as part of a 16-ship Russian Navy formation, according to satellite photos taken on Thursday.

Slava-class cruisers RTS Marshal Ustinov (055) and RFS Varyag (011) were part of a 16-ship formation in Syrian territorial waters near Russia’s sole foreign naval base in Tartus as captured by European Space Agency’s satellite imagery, reported Naval News.

“This is the concentration of essentially the entire Russian Navy in the Mediterranean, in one place. Ordinarily, these vessels would be operating in distinct groups,” reads the report from Naval News.
