Russia has celebrated the country's Navy Day with festivities at all main fleet bases, from the Baltic and Black seas to the Pacific Ocean.
One of the most spectacular celebrations took place in Sevastopol, home to a Russian naval base on the Crimean Peninsular in Ukraine.
Alexander Kovshar, Commander Consultant, Black Sea Fleet, said, "The Navy Day is a number one celebration for the heroic city of Sevastopol, for the navy servicemen who are serving on the front line to protect the vital interests of both the Russian and the Ukrainian people."
The day-long event included a convoy of warships as well as a number of combat displays, including the enactment of a landing mission and the mock-seizure of an enemy ship. Russian media says the event was watched by tens of thousands of people, who flocked to the city for the maritime spectacle.
The Russian fleet in Sevastopol is made up of about 16,200 servicemen, a rocket cruiser, a large destroyer and about 40 other vessels including submarines, landing craft, small destroyers and support ships.
