– The Northern Fleet is one of the Russian Navy's fleets and Russia's most important military force (sea, air, and land forces) in the Arctic.
– In 2014, a joint operational strategic command for Arctic operations was established at the Northern Fleet's headquarters in Severomorsk, Murmansk County.
– In 2021, the Northern Fleet also gained status as one of Russia's most central military-administrative units (on par with a military district). The unit includes the Republic of Komi, the counties of Arkhangelsk and Murmansk, and the Nenets Autonomous Area.
– The Northern Fleet's status has changed due to the re-establishment of the Leningrad and Moscow military districts. The reorganization is being done in light of Finland's NATO membership and Sweden's upcoming admission to the alliance, Russia's defense minister said in December.
– The Northern Fleet has a large area of responsibility, which includes the North Atlantic, the Barents Sea, and the border areas with Norway and Finland, as well as Russian Arctic sea areas as far east as the East Siberian Sea. The fleet's ships are also periodically sent on operations elsewhere in the world.
– Most of the Northern Fleet's bases and garrisons are located on the Kola Peninsula, located near the borders with Norway and Finland. Russia has also upgraded and expanded its military infrastructure in the Arctic over the past 10-12 years, such as on the archipelagos of Novaya Semlya, Franz Josef Land, and the New Siberian Islands.
