The drills come amid heightened tensions between Moscow and the West over Ukraine and reports that the United States might send extra troops to the region.
Moscow said last week it would stage a series of drills involving all its fleets in the seas directly adjacent to Russia. The exercises will also include maneuvers in the Mediterranean, the North Sea, the Sea of Okhotsk, the northeast Atlantic Ocean and the Pacific.
Russian military moves are being closely watched by the West at a time when a troop build-up near its border with Ukraine has sparked fears of a conflict. Moscow has denied it plans to launch an attack on Ukraine.
