The Defence Secretary has accused Russia of staking a claim in the region and militarising its frozen expanses, but how strong is the Norwegian military, and how does it compare to Russia's strength?
Norway is a founding member of the NATO, which was created in 1949 to counter military threats from the Soviet Union.
Its population of 5.3 million has a 196-kilometre (122-mile) border with Russia (population: more than 142 million) and there are concerns that tensions between NATO and Russia could spill over into the Scandinavian country.
It is unlikely that, as a member of NATO, Norway would be left to face Russia alone, but although the Norwegian military is small (23,950 active personnel) they are also ranked among the most modern forces in the world.
According to figures from the International Institute of Strategic Studies (IISS), Norway’s military looks like this:
Norwegian Army: 9,350 personnel. Armoured vehicles include 36 Leopard 2A4O main battle tanks and 89 CV9030 Fighting Vehicles as part of the Army's mechanised infantry.
Norwegian Navy: 4,300 personnel. Five Fridtjof Nansen-class frigates and six Ula-class submarines.
Norwegian Air Force: 3,600 personnel. Seventy-three aircraft including 57 F-16 Fighting Falcons. Norwegian F-16s have participated under operations in Afghanistan, and two jets are constantly on 15-minute standby for NATO.
