Expanding U.S. Reach in the High North:
Coast Guard Icebreaker Storis Completes First Winter Patrol
The U.S. Coast Guard’s newest icebreaker, USCGC Storis, has completed its first late winter patrol in the Bering Sea and Arctic, marking a significant milestone in Washington’s push to rebuild year-round polar capabilities amid growing strategic competition in the region.

After a 36-day deployment that tested the cutter in some of the harshest operating conditions in the Arctic, Storis returned to Seattle earlier this month after logging more than 4,800 nautical miles while conducting ice assessments, interoperability drills, logistics experiments, and search-and-rescue training.
The deployment represented the first sustained Arctic patrol in winter conditions for the recently acquired vessel, which the Coast Guard commissioned in 2025 after purchasing the former commercial icebreaker Aiviq in late 2024.
Storis is the first polar icebreaker added to the U.S. fleet in more than two decades and is intended to provide immediate operational capacity while the service undertakes a much larger expansion of its icebreaking force.
“Operating the Storis in the extreme conditions of an Arctic winter is a clear statement of our nation’s resolve,” Capt. Corey Kerns, commanding officer of the cutter, said in a Coast Guard statement.
“Storis represents a critical bridge to our future icebreaker fleet. This mission is about preparation, rigorous training and asserting the continued importance of the Arctic to our nation.”
This exercise demonstrates Storis’s unique capability
A changing Arctic
During the patrol, Storis operated alongside the Legend-class national security cutter USCGC Waesche in a series of exercises near the ice edge in difficult winter conditions, including low visibility and heavy weather.
The cutters conducted a joint passing exercise designed to test interoperability between high-endurance surface assets operating in Arctic waters.
One of the more closely watched demonstrations came in Dutch Harbor, Alaska, where Storis and Waesche completed a fueling-at-sea exercise. According to a Coast Guard social media post, the operation was designed to validate a new logistics concept allowing the icebreaker to remain on station longer without returning to port.
“This exercise demonstrates Storis’s unique capability within the National Fleet to sustain forces in the high latitudes – extending asset time on station, maximizing the nation’s operational footprint, and ensuring the Coast Guard remains always ready in the High North,” the service wrote.
The deployment also included cold-weather rescue drills, ice rescue team training, and live-fire gunnery exercises intended to prepare the crew for future missions in an increasingly contested Arctic environment.
Coast Guard officials said the patrol focused heavily on evaluating the cutter’s performance envelope in sea ice and collecting baseline operational data for future deployments by both U.S. and allied vessels.
Storis is a 360-foot medium icebreaker capable of breaking through roughly three feet of ice at five knots. While not nearly as powerful as the heavy icebreaker USCGC Polar Star, the vessel significantly expands the Coast Guard’s ability to maintain a persistent presence in Arctic waters alongside the medium icebreaker USCGC Healy.
A dozen new icebreakers
The cutter’s arrival comes as the United States accelerates efforts to modernize and enlarge its aging polar fleet. Earlier this year, the Coast Guard finalized contracts for 11 new Arctic Security Cutters under a fast-tracked acquisition effort involving U.S., Canadian, and Finnish shipbuilding expertise.
Contracts involving Davie Defense, Bollinger Shipyards, and Finnish yards were recently completed as Washington seeks to rapidly close the capability gap with Russia and China in polar operations.
Under the program, several cutters will be built in Finland before production expands in U.S. shipyards, leveraging Helsinki’s globally recognized icebreaker construction expertise to accelerate deliveries. The first Arctic Security Cutter is expected to enter service in 2028.
Until then, Storis is expected to shoulder a growing share of operational demand in the Arctic.
The cutter will likely return north this summer alongside Healy during what is shaping up to be another active season in the region.
Last year, five Chinese research vessels and icebreakers conducted extensive operations near the edge of U.S. waters in the Arctic, drawing repeated monitoring by Coast Guard cutters, aircraft, and other American assets, including Healy and Storis.
Although the cutter’s next mission has not yet been formally announced, vessel tracking information recently indicated Japan as Storis’ upcoming destination, suggesting another major Pacific deployment could already be in planning.
For the Coast Guard, the latest patrol underscored both the urgency and the challenge of maintaining credible Arctic access while a new generation of American icebreakers remains years away from delivery.
