 The General Staff source, who was not named, had said that after calling in at Tartus they would head for the Bosphorus and the Russian Black Sea port of Novorossiysk.From 2013 on, ten Ropucha-class ships, gathered from all four Russian fleets, were used to transport military equipment from Novorosiysk to Tartus in Syria, during an intervention in Syrian civil war, along with "Ropucha"-class ships.The Ukrainian Navy's only ship of the class, "Kostiantyn Olshansky", was reportedly seized by Russia's troops and accepted into service with the Russian Navy after the Annexation of Crimea by the Russian Federation in March 2014.
