The Soviet Navy (Russian: Военно-морской флот СССР, Voenno-morskoj flot SSSR, literally "Naval Fleet of the USSR") was the naval part of the Soviet Armed Forces. Often referred to as the Red Fleet, the Soviet Navy would have been instrumental in any perceived Warsaw Pact role in an all-out war with NATO when it would have to stop the naval convoys bringing reinforcements over the Atlantic to the Western European theatre. Such a conflict never occurred, but the Soviet Navy still saw considerable action during the Cold War. The Soviet Navy was divided into several major fleets: Northern Fleet, the Pacific Ocean Fleet, the Black Sea Fleet, the Baltic Fleet, and, as a separate command, the Leningrad Naval Base. The Caspian Flotilla was a semi-independent formation administratively under the Black Sea Fleet command while the Soviet Indian Ocean Squadron drew its units from and was under the jurisdiction of the Pacific Ocean Fleet. Other components included the Naval Aviation, Naval Infantry (the Soviet equivalent of marines), and coastal artillery. The Soviet Navy was reformed into the Russian Navy after the Dissolution of the Soviet Union in 1991.
