Authentic Icebreakers

50 Years of Victory

Twenty years in the making, 50 Years of Victory is the first Arktika-class icebreaker to have a spoon-shaped bow, capable of breaking through ice up to 2.5 meters (9.2 feet) thick! This is one of the world’s largest, most-powerful nuclear icebreaker.

Kapitan Khlebnikov

The Kapitan Khlebnikov is a polar-class icebreaker combing power and technology with comfort. No passenger ship has transited the Northwest Passage more often than the renowned Kapitan Khlebnikov. Originally designed to take on the rigors of northern Siberia, the 24,000 horsepower engine and advanced ice-breaking technology take passengers places no other ship can.
