The nuclear icebreaker Lenin, the pride and joy of the Soviet Union's Arctic great game, lies at perpetual anchor in the frigid water here. A relic of the Cold War, it is now a museum.

But nearly three decades after the Lenin was taken out of service to be turned into a visitor attraction, Russia is again on the march in the Arctic and building new nuclear icebreakers.

It is part of a push to firm Moscow's hand in the High North as it vies for dominance with traditional rivals Canada, the United States and Norway, as well as newcomer China.
