The United States Coast Guard\u2019s heavy icebreaker USCGC Polar Star (WAGB 10) has departed Seattle for its months-long deployment to Antarctica, beginning its 29th mission in support of Operation Deep Freeze.<\/p>\n
The annual joint military operation is responsible for resupplying America\u2019s Antarctic stations, which are overseen by the National Science Foundation as part of the United States Antarctic Program.<\/p>\n
This deployment comes as the U.S. government makes what was described as a historic investment of nearly $25 billion, including $9 billion specifically allocated to new icebreakers and high-latitude infrastructure, aimed at strengthening national access, security and leadership in polar regions.<\/p>\n
Until the new Polar Security Cutters and Arctic Security Cutters are commissioned in the coming decade, Polar Star remains the only American vessel capable of breaking a channel through Antarctic ice to reach McMurdo Station, the largest U.S. base on the continent and the main logistics hub for the Antarctic programme.<\/p>\n
Each year, the cutter opens a navigable route through the Ross Sea to allow fuel and supply vessels to reach the station, ensuring the continued operation of U.S. Antarctic research and logistical activities.<\/p>\n The mission is regarded as essential for safeguarding American security, economic and environmental interests in the high latitudes, as well as for supporting allied partnerships.<\/p>\n The cutter\u2019s commanding officer, Capt. Jeff Rasnake, said that the crew has worked diligently to maintain and operate the ageing vessel.<\/p>\n He was also reported as saying that every year presents new challenges, and he expressed pride in how the crew prepared during maintenance and logistical planning ahead of this deployment cycle.<\/p>\n Polar Star, which entered service in 1976, is 399 feet long, has a displacement of 13,500 tonnes, and a draft of 34 feet.<\/p>\n Despite approaching its 50th year of service, it remains the most powerful non-nuclear icebreaker in the world, capable of generating up to 75,000 shaft horsepower.<\/p>\n The continuous effort by the crew to sustain the vessel\u2019s capability is seen as vital to ensuring U.S. access to the continent until replacement ships enter service.<\/p>\n![\"USCG\"](\"https:\/\/i0.wp.com\/www.marineinsight.com\/wp-content\/uploads\/2025\/11\/USCG-5.jpg?resize=1200%2C628\")
