US Polar Icebreaker Visits San Diego

The U.S. Coast Guard’s polar icebreaker Cutter Polar Star has made a brief stop in a warmer climate, mooring in San Diego before returning to Seattle after a four and a half month-long deployment to the Antarctic in support of Operation Deep Freeze 2016. The Polar Star, a 399-foot cutter commissioned in 1976, is the nation’s only operational heavy icebreaker, and the most powerful non-nuclear icebreaker in the world.
