Russia has unveiled a new Arctic military base capable of housing 150 troops as well as nuclear-ready warplanes.
The triangular complex, painted in the red, white and blue of the Russia's tricolor flag, has been built in remote Alexandra Land in the Franz Josef Archipelago.
While parts of the base remain top secret, military chiefs have offered a glimpse at the interior of the building.
It comes as part of Russia's largest Arctic military push since the fall of the Soviet Union and as Moscow moves to lay claim to the region's huge oil and gas reserves - believe to be worth as much as £23trillion.
The five-storey complex, named Nagursky by Defense Minister Sergei Shoigu, is on the extreme north of Russia's Arctic frontier.
It will hold 150 troops able to survive autonomously in subzero conditions for 18 months.
Officials have said they may deploy military jets there. MiG-31 fighters, designed to shoot down long-range bombers, or the SU-34, a frontline bomber are seen as options, it has been reported.
