Top secret nuclear sub used to prove North Pole claim
First known mission with the Russian Northern Fleet’s unique “Losharik” deep diving titanium submarine was done at a depth down to 3,000 meters at the Mendeleyev ridge this September.

The submarine took part in the “Arctic-2012” expedition this autumn aimed at proving Russian ownership of the Mendeleyev ridge stretching across the East Siberia Sea towards the North Pole. Russia will use the data collected in its application to the UN Law of the Sea, that within the next few years will divide the continental shelf among the Arctic costal states, including the North Pole itself.

Officially, and as reported by BarentsObserver last week, the expedition was headed by the two icebreakers “Dikson” and “Kapitan Dranitsyn.” Little has so far been known about what happened under water.
