Kremlin sources said the frigate Admiral Essen tracked down and stalked the US sub in April as fears of all-out war in the region grew with Britain, the US and France carrying out joint airstrikes against the Syrian regime.
According to the sources, the Admiral Essen from the Russian Black Sea Fleet homed in on an Ohio-class submarine during its Mediterranean deployment between March and June.
The pursuit lasted for more than two hours and the Russians claim the ship recorded the basic parameters of the US submarine.
Izvestia newspaper speculated the submarine might have been the cruise missile-carrying USS Georgia.
Nuclear submarines are complex objects for detection
Vladimir Ambartsumyan, who once served as a commander on the naval brigade within the Russian Northern Fleet, told Izvestia that even locating a submarine in the sea was a great success.
He said: “Nuclear submarines are complex objects for detection.”
The sources said the incident took place in April as Britain, the US and France bombed Syria after the brutal regime of Bashir al-Assad launched deadly chemical attacks on the town of Douma.
The Pentagon has not commented on he claims but according to available US military data, Ohio-class submarines are armed with “tactical missiles and equipped with superior communications capabilities.”
These submarines are able to launch an “unprecedented strike” from a “stealthy, clandestine platform.” They are also capable of “launching missile strikes and supporting Special Operation Forces (SOF) missions.”
The Admiral Essen, which carries eight vertically-launched Kalibr cruise missiles, is one of Russia’s most modern warships.
The Russian ship left Sevastopol, a major Black Sea port located on the Crimean Peninsula, on March 13 and returned on June 30.
The frigate was deployed most of the time in the Mediterranean Sea.
Naval commanders also used the ship to attack ISIS targets during the Russian operation in Syria last year.
Kremlin officials said the warship successfully struck ISIS command and control centres as well as ammunition depots on several occasions.
