In April 2017, Russia unveiled an Arctic Trefoil military base on Alexandra Land Island in the northeast Barents Sea. It is Russia's northern-most military outpost, and the second of its kind following the completed Northern Clover on Kotelny. Alexandra Land is also home to the upgraded Nagurskoye Airbase. Rather than ensuring these new Arctic bases remain secret, the Russian government is encouraging virtual tours of its state-of-the-art, three unit clover-like compound which is designed to withstand severe weather. Russia's military posture on Alexandra Land provides air, sea, and land capabilities which reinforce Russia's multi-layered maritime and air denial capabilities; safeguard the Kola Peninsula which is home to Northern Fleet headquarters and Russia's advanced Arctic land, air, and naval assets including its nuclear arsenal and second-strike capabilities; and ensure Russia's access to and control over the Northern Sea Route. Geographically, Alexandra Lands proximity to the Greenland-Iceland-Norway (GIN) and Greenland-Iceland-United Kingdom (GIUK) gaps and its increased capabilities could disrupt NATO's vital sea lines of communication (SLOC) between North America and Europe, hindering U.S. military reinforcement to Europe.


Alexandra Land Island (Ostrov Zemlya Aleksandry) is the largest island in Russia's Franz Josef Land Archipelago (Zemlya Frantsa-Iosifa), and its strategic importance to Russia's national defense and presence in the Arctic dates back to the early 1950s.1 During the Cold War the former Soviet Union established and maintained the Nagurskoye Airbase, which included the 31st Separate Radar Company, a meteorological station, a small dirt/snow airfield (known as the Nagurskoye Snow Strip), and likely small signal and communication intelligence collection units. Following the collapse of the Soviet Union, these facilities were substantially reduced to a FSB [Federal Security Service] border post (30 persons), Arctic specialists (16 persons) and meteorologists (six persons) who lived and work there.2

An important shift in Russia's military doctrine in 2008, which elevated the strategic importance of the Arctic, revived Alexandra Land's importance to the Kremlin. The reconstitution of the Nagurskoye airbase and construction of new facilities better secures northern approaches to Russia's coastline, protects its vast mineral and energy resources, and improves monitoring of maritime shipping activity across the Northern Sea Route. President Putin personally visited Franz Josef Land in April 2010 following a maritime border demarcation agreement in the Barents Sea between Russia and Norway, paving the way for oil and gas exploration along the maritime border.

Five years later in 2013, the Russian Defense Ministry announced that would reestablish a regular naval and military presence in the Arctic.3 As part of its plan, the meteorological station on Alexandra Land would be supplemented by the addition of permanent military facilities that would include a new airbase, housing and administration trefoil, air traffic control and air defense units and radars, and other support installations.4

Construction moved quickly, and in November 2014 units of the Northern Fleet's air defense division deployed to Alexandra Land and were housed in a temporary camp.5 The following month construction of the housing and administration trefoil began. In October 2015 Northern Fleet Commander Admiral Vladimir Korolev stated that construction of the trefoil was 60 percent completed.6 By the fall of 2016, the trefoil compound was completed.7

In April 2015 it was announced that a new 2,500-meters-long temporary seasonal airfield covered with ice would be constructed on Alexandra Land to accept delivery of personnel and cargo.8 The following year, it was announced that this new airfield would be extended to a Class 2 year-round runway [and would] have dimensions of 2.5-kilometers-by-42-meters and be completed by the end of 2016.9 That same month Russian Defense Minister Sergei Shoigu announced that a group of either Su-34 multirole fighter aircraft or MiG-31 fighters would be based at the new Nagurskoye Airbase, alongside Il-78 tankers.10 When completed, the airbase and air units would consist of heated hangars for Su-34 or MiG-31 aircraft, an aviation headquarters, a separate radar company, air traffic control facility, antiaircraft artillery battalion, and communications and support sub-units. Nagurskoye Airbase would be capable of receiving and basing of all type of aircraft, including strategic bombers, and defending itself.11

With the upgrade to Nagurskoye Airbase, Russia has established a new air defense division in the Arctic which includes the units on Franz Josef Land (to include Alexandra Land Island), and units on Novaya Zemlya, Severnaya Zemlya, the New Siberian Islands, Cape Schmidt, Wrangle Island and Tiksi, covering an area of approximately 4,800 km.12


Location, Location, Location

Alexandra Land's location advances two Russian objectives in the Arctic: (1) it enhances Russian territorial defense and (2) improves monitoring and control over maritime activity across the Northern Sea Route. As its northern most military installation, Alexandra Land pushes Russia's military and forward line of defense further north into the Arctic Ocean, making it a key outpost to observe NATO activity and capabilities. Considering that the four other Arctic coastal states are NATO members, Alexandra Land effectively represents a marker, stymieing what Russia may interpret as NATO expansion in the region. The Sopka-2 radar system improves Russian air and maritime domain awareness in the Arctic and supplements Russia's strategic early warning radar network to detect U.S. or NATO aircraft and missiles when flying over the top.

Similar to the Sopka-2 radar installation on Wrangel Island, Alexandra Land is part of a larger network covering Russia's northern border in the form of a protective dome against foreign aircraft, missiles, and ships.

Alexandra Land is also situated along the Northern Sea Route. In anticipation of increased maritime activity, the Russian government increasingly seeks to enhance its surveillance, enforcement, and defensive capabilities along the route. There are also growing concerns about potential military activity. In March, the Russian government imposed limits on foreign warships transiting the NSR, requiring 45 days notice for voyages. This new limitation runs counter to international maritime law as the majority of the international community views the NSR as an international passage meaning freedom of navigation should be permitted, although it is rarely tested in the Arctic. This is a concerning development that could hinder the conduct of innocent passage through the NSR.

Defending Against "Over the Top" Threats

Alexandra Land plays a critical role in protecting the Kola Peninsula, home to the Northern Fleet headquarters at Severomorsk. The Kola Peninsula is a vital center of Russia's military power because of its modernized nuclear submarine fleet and nuclear missiles and conventional long-range high-precisions cruise missiles. Multiple layers of defense consisting of maritime and land capabilities serves two crucial functions: denying access to foreign naval forces and ensuring the survivability and second-strike capability of strategic ballistic missile submarines.13 The Kola Peninsula is increasingly fortified by Arctic outposts like Alexandra Land which develops military supremacy out to the Greenland-Iceland-United Kingdom (GIUK) gap while strengthening Russia's bastion defense capabilities.

Displaying its growing military strength in the Arctic, in June, Russias Northern Fleet tested the Tor-M2DT missile system, with a missile range of 15 kilometers. According to reports, the Tor-M2DT is likely to be deployed to several remote military installations, including Franz Josef Land. Tests of the new system follow reports of past deployments of notable air defense assets including the S-300 (NATO: SA-10 Grumble) air defense system and the Pantsir-S1 anti-aircraft system. Complimented by the rumored presence of K-300P Bastion-P (NATO SSC-5) coastal defense systems armed with P-800 Oniks anti-ship cruise missiles (NATO: SS-N-26 strobile) and 4K51 Rubezh (NATO: SSC-3 Styx) anti-ship system, Alexandra Land would be a center point of a developing A2/AD bubble extending into international waters of the Central Arctic Ocean and Barents Sea. However, none of the satellite images analyzed capture such equipment.

But We Can Speculate About Power Projection Scenarios

While Alexandra Land's primary function is to enhance Russian air and coastal defense, the growing military capabilities on Nagurskoye Airbase suggest that Alexandra land could be a staging location for future offensive and power projection capabilities. Following the upgrades in 2016 to a Class 2 year-round runway, Nagurskoye Airbase is now capable of hosting fighter and refueling aircraft, notably Su-34 and MiG-31 fighter jets and Il-78 refueling tankers. Based on a 2018 Danish Intelligence Risk Assessment, Russian aircraft based at Nagurskoye Airbase are capable of reaching the airspace over north-eastern Greenland with little prior warning. Supported by air-to-air refueling, Russian combat aircraft could reach Thule Air Base, a key installation in the U.S. space and missile defense architecture while also enlarging Russia's A2/AD bubble into the North Atlantic.

The size and scale of recent Russian exercises in the Barents and Norwegian Seas suggest that it seeks to practice and test its expanding defense capabilities in the North Atlantic. In August, the Northern Fleet completed a comprehensive naval aviation exercise involving more than 50 aircraft, including fighter jets, bombers, Tu-142 anti-submarine planes, Il-38, MiG-31, Su-33 and Su-24 fighter jets in addition to nearly 2,000 ground personnel. The maritime component of the drill included 30 Russian naval vessels including surface ships, submarines, and supply ships. Norwegian Chief of Defense Haakon Bruun-Hansen suggested these are exercises designed to block NATO's access to the Baltic Sea, North Sea, and Norwegian Sea, hindering NATO reinforcements to Norway. Importantly, Russian forces for this exercise emanated from Russia's Northern, Baltic, and Black Sea fleets, suggesting that NATO should reconceptualize its understanding of how Russia will defend the Arctic and what resources NATO would draw upon to defend its allies.


Alexandra Land and Nagurskoye Airbase increase Russia's air and maritime defense capabilities in the Arctic. The most concerning aspect, however, is Alexandra Land's potential as a staging ground for power projection into the Central Arctic and North Atlantic. The Trefoil compound and its support facilities raise the level of readiness of Russia's Arctic forces potentially to the point where Norway's freedom of action and movement is restricted and potential Allied access to the North Atlantic is cut off. Sending NATO reinforcements to defend Norway would prove challenging, and NATO's freedom of navigation in the Arctic could be reduced. At the moment, however, the satellite imagery does not indicate such an expansion is occurring or capabilities are present.

The ongoing Russian military exercise, Tsentr-2019, should provide greater insight into new Russian Arctic capabilities as well as Alexandra Land's role in Russia's bastion defense. There are reports of significant quantities of deliveries to Franz Josef Land prior to Tsentr. The U.S. and NATO must closely monitor and analyze the Tsentr exercise to examine shifts in and changes to Russia's Arctic military posture.
