The Russian Ministry of Defense said Friday that six landing ships arrived in the port of Tartus in western Syria, located in the eastern Mediterranean Sea. Syria’s official news outlet SANA also reported the story. Landing ships are large naval vessels that can carry smaller warships and amphibious vehicles. 

The news demonstrated the continued importance of Tartus, which is the only Mediterranean port that Russia has access to. Russia built a naval facility there in 1971, but its presence gained more media coverage after the start of the Syrian civil war in 2011. Armed opposition forces ultimately pushed into the neighboring coastal province of Latakia, but the Russian military intervention in 2015 turned the tide of the war in the Syrian government’s favor. 

Forces loyal to Syrian President Bashar al-Assad now control most of the country, and Tartus is not at risk of falling into rebel hands. 

The port of Tartus has considerable strategic value for Russia to counter the expansion of the North Atlantic Treaty Organization (NATO) on its borders in Europe. To this end, Russia wants to create a military threat on NATO’s southern flank in the Mediterranean from Tartus, Anton Mardasov wrote in Al-Monitor in December. NATO members Turkey, Greece and Italy are positioned above Syria in the eastern part of the sea.
