Russia has sent two modernized submarines equipped with advanced stealth technologies to the Mediterranean Sea as part of efforts to reinforce naval presence off the Syrian coast.
"The Black Sea fleet's new large diesel and electric submarines, Kolpino and Veliky Novgorod ... have arrived in the Mediterranean," the Russian Defense Ministry said in a statement on its website on Aug. 28.
The ministry added that the two stealth submarines were fitted with new navigation systems, fully automatized control systems, high-precision missiles, and powerful torpedo equipment.
The submarines, classified by NATO as "Improved Kilo" class, were built in the northwestern city of Saint Petersburg and are designed for anti-ship and anti-submarine operations in mid-depth waters. They are capable of holding a crew of 50 and have a top underwater speed of 20 knots and a cruising range of 400 miles.

Part of Russia's Black Sea fleet is engaged in the battle against the Daesh Takfiri terrorist group in Syria.
Moscow launched its campaign against Daesh and other terror outfits in Syria at the Damascus government's request in September 2015. Its airstrikes have helped Syrian forces advance against militant groups fighting to overthrow President Bashar al-Assad's government.
Syria has been fighting different foreign-sponsored militant and terrorist groups since March 2011.
Damascus blames the deadly militancy on some Western states and their regional allies.
