The 159 crewmembers of the U.S. Coast Guard cutter Polar Star (WAGB 10) arrived yesterday at McMurdo Station, Antarctica, following a 58-day transit from the U.S. The cutter departed its homeport of Seattle on Nov. 26.

This year marks the Polar Star’s 23rd journey to Antarctica in support of Operation Deep Freeze, an annual joint military service mission to resupply the U.S. Antarctic stations, in support of the National Science Foundation, the lead agency for the U.S. Antarctic Program.

The 399', 13,000-ton Polar Star arrived after creating a 23-mile channel through the ice to McMurdo Sound, which will enable the offload of over 19.5 million lbs. of dry cargo and 7.6 million gals. of fuel from three logistic vessels. Together these three ships carry enough fuel and critical supplies to sustain NSF operations throughout the year until Polar Star returns in 2021.

Each year, the Polar Star crew creates a navigable channel through seasonal and multiyear ice, sometimes as much as 21' thick, to allow refuel and resupply ships to reach McMurdo Station.

“I am immensely proud of all the hard work and dedication the men and women of the Polar Star demonstrate each and every day,” said Greg Stanclik, commanding officer of the Polar Star. “Maintaining and operating a 44-year-old ship in the harshest of environments takes months of planning and preparation, long workdays and missed holidays, birthdays and anniversaries with loved ones. The Polar Star crew truly embodies the ethos of the Antarctic explorers who came before us — courage, sacrifice and devotion.”

Operation Deep Freeze each year, the ship spends the winter breaking ice near Antarctica, and when the mission is complete, returns to dry dock in order to conduct critical maintenance and repairs in preparation for the next Operation Deep Freeze mission.

If a catastrophic event, such as getting stuck in the ice, were to happen to the Coast Guard cutter Healy (WAGB 20) in the Arctic or to the Polar Star near Antarctica, the U.S. Coast Guard is left without a self-rescue capability.

By contrast, Russia currently operates more than 50 icebreakers – several of which are nuclear powered.

The Coast Guard has been the sole provider of the nation’s polar icebreaking capability since 1965, and is seeking to increase its icebreaking fleet with six new polar security cutters to ensure continued national presence and access to the Polar regions.

In April, the Coast Guard awarded VT Halter Marine Inc., Pascagoula, Miss., a contract for the design and construction of the Coast Guard’s lead polar security cutter, which will be homeported in Seattle. The contract also includes options for the construction of two additional PSCs.

"Replacing the Coast Guard's icebreaker fleet is paramount," said Vice Adm. Linda Fagan, commander of the Coast Guard's Pacific Area. "Our ability to clear a channel and allow for the resupply of the United States' Antarctic stations is essential for continued national presence and influence on the continent."
