The USCGC Polar Star icebreaker sails every year to break the ice and create a navigable channel in the frozen waters of Antarctica. We show you a video of it’s trip, in which you can see how the ice breaks through the cameras placed on the helmet.
The channel that opens this icebreaker allows supply vessels to reach the McMurdo Station of the US National Science Foundation. Its annual presence supports Operation Deep Freeze (denomination of US operations in that continent as regular replenishment missions of its Antarctic bases).
The crew faced this year during the mission to numerous mechanical challenges on board, including two flooding incidents and the loss of one of the three main turbines.
USCGC Polar Star (41 years old) and USCGC Polar Sea (now retired) are the most powerful conventional propulsion icebreakers in the world. Polar Star was built by the shipyard Lockheed Shipbuilding and Construction Company, located in Seattle.
