Satellite images appearing to show Russia beefing up its military presence in the Arctic have emerged just days after three of Moscow's nuclear ballistic missile submarines smashed through the polar region in a show of strength.
The images show the Russian military has been rebuilding and expanding numerous facilities across the Arctic in recent years.
From revamping runways to deploying additional surveillance and air defence assets, the satellite images reveal a continuous effort to expand Moscow's capabilities in the polar region.
Underground storage facilities have also been pictured and experts fear they will be used for the Poseidon 2M39 torpedo - a nuclear-powered underwater drone that can be launched from a submarine and carry nuclear warheads.
