With tensions escalating between Russia and Turkey following the downing of the Russian Su-24, rumours are once again doing the rounds that the Kremlin is sending the world's largest submarine, Dmitri Donskoy (TK-208), Nato-code name Typhoon to the Mediterranean Sea.
On 24 November, Turkey shot down a Russian jet, alleging that it violated its airspace - an accusation that Russia had denied.
One Russian pilot was killed, while another Russian soldier part of the rescue crew was shot dead by Syrian rebels during the rescue mission to save the second pilot of the downed jet.
Since then the tension between Ankara and Moscow has only escalated. An angry Russia, now has turned Syria into a no-fly zone by deploying its highly advanced Russian S-400 anti-aircraft missiles at the Khmeimin base, Russia's military enclave in Syria near Latakia.
After the deployment of the S-400, US and Turkey suspended their attacks on Isis in Syria, a Military Times report had confirmed.
Russia now has accused Turkey of having shot down its jet to protect Isis' oil trucks.
Back in September, the Israeli military intelligence website, DEBKAFile had said that Russia was sending in the world's largest submaraine, Typhoon to the Syrian coast.
The report had noted that the sub was armed with 20 Bulava (NATO-code SS-N-30) intercontinental ballistic missiles and 200 nuclear warheads with a reported range of 10,000km.
