The U.S. Coast Guard is advancing in the final phase of a life extension initiative for its sole operational heavy-class icebreaker, the USCGC Polar Star (WAGB-10). Currently stationed at the Mare Island Dry Dock in Vallejo, California, the Polar Star is undergoing a comprehensive overhaul aimed at extending its lifespan until the forthcoming next-generation cutters are available in the 2030s.
This critical maintenance phase focuses on several essential upgrades. Key renovations will enhance the ship’s heating, air conditioning, and ventilation systems, while navigation equipment is set for a significant upgrade. Additionally, the overhaul will include the replacement of the vessel’s main propulsion and auxiliary systems, ensuring improved operational reliability and efficiency. The revitalization process aims to bolster the icebreaker’s accommodations, safety features, and navigational capabilities, essential for fulfilling its missions during extended deployments in challenging environments.
In tandem with the extensive refurbishment, a specialized team from Baltimore will be on-site this summer to conduct supplementary repairs, specifically targeting the cutter’s sewage pumps and tank level indicators.
ISVS Program Manager Kenneth King highlighted the significance of this initiative, stating, “The efforts of the joint In-Service Vessel Sustainment Program (ISVS) and the Long Range Enforcer Product Line team align with one of the key goals of Force Design 2028, to rapidly deliver the assets the service needs to fulfill its commitment to the American people.” He noted that this phase marks a pivotal achievement for both the Polar Star and the ISVS program, reflecting the dedication of the professionals working to ensure the vessel can successfully undertake its multifaceted missions in polar regions until the deployment of the polar security cutter fleet.
The USCGC Polar Star itself is an impressive engineering feat, measuring 399 feet (122 meters) in length with a beam of 84 feet (26 meters). Powered by six diesel engines, each providing 3,000 horsepower, alongside three gas turbines that produce a total of 75,000 horsepower, the vessel is capable of accommodating over 120 personnel. It plays a crucial role in a variety of operations, supporting salvage missions, scientific research, and icebreaking in zones characterized by up to 21 feet (6 meters) of thick ice.
On open water, the icebreaker can achieve speeds of 18 knots (approximately 21 miles or 33 kilometers per hour), while it can maneuver through ice at about 3 knots (3 miles or 6 kilometers per hour). With a robust operational range of 16,000 nautical miles (equivalent to 18,412 miles or 29,631 kilometers), the USCGC Polar Star is uniquely equipped to service the demands of the polar environment, ensuring a vital presence in these strategic and often inhospitable regions.
