Polar Star, only US icebreaker, returns to port in Seattle after 6 months in dry dock
The 399-foot, 13,000-ton cutter is the nation’s only operational heavy icebreaker.
“We successfully accomplished an annual dry dock availability valued at over $7.6 million,” stated Lt. Cmdr. Chris Pelar, Polar Star’s engineering officer. “More than 50 work items were completed while in dry dock. We will complete remaining maintenance requirements in Seattle before departing for our upcoming Antarctic deployment.”
The 42-year-old icebreaker will head for the Ross Sea and forcibly break through ice up to 21-feet thick to clear a channel so supply ships can reach Antarctica’s McMurdo Station, Scott-Amundsen South Pole Station and other international bases.
