Arktika (Russian: А́рктика, IPA: [ˈarktʲɪkə]; literally: Arctic) is a retired nuclear-powered icebreaker of the Soviet (now Russian) Arktika class. In service from 1975 to 2008, she was the first surface ship to reach the North Pole, a feat achieved on August 17, 1977, during an expedition dedicated to the 60th anniversary of the October Revolution.[2]
The Arktika is a double-hulled icebreaker; the outer hull is 48 millimetres (1.9 in) thick, the inner 25 millimetres (0.98 in) thick, with the space in between utilized for water ballasting. At the strongest point, the cast steel prow is 50 centimetres (20 in)) thick and bow-shaped to aid in icebreaking, the curve applying greater dynamic force to fracture the ice than a straight bow would.[citation needed] The maximum ice thickness it can break through is approximately 2.8 metres (9 ft 2 in).[citation needed] Arktika also has an air bubbling system (ABS) which delivers 24 m3/s of steam from jets 9 metres (30 ft) below the surface to further aid in the breakup of ice.[3]
The ship is divided by eight bulkheads, providing nine watertight compartments, and can undergo short towing operations when needed. It also comes equipped with a helicopter pad and hangar at the aft of the ship.[3] Mil Mi-2 "Hoplite", dubbed ptichka (Russian for "little bird"), or Kamov Ka-27 "Helix" helicopters are used for scouting expeditions to find safe routes through the ice floes.[4]
