U.S. Coast Guard patrols Arctic, tracks Chinese research ships and drills with Canada
The Coast Guard cutter Munro spent nearly four months in the Arctic, monitoring three Chinese-flagged research vessels and conducting joint exercises with the Royal Canadian Navy.
The Coast Guard’s Legend-class cutter Munro completed a four-month Arctic mission, patrolling the northern maritime approaches of the United States. While on station, the ship’s crew observed three Chinese-flagged research vessels, ensuring they adhered to international maritime rules. The deployment included combined drills with the Royal Canadian Navy, improving joint situational awareness and integrating command-and-control networks under Operation Tundra Merlin.
Munro’s team also worked with law-enforcement partners to inspect commercial fishing boats in the Bering Sea, protecting a multi-billion-dollar fishery. The mission reflects expanded Arctic defense cooperation between the United States and Canada, supported by recent shipbuilding contracts for polar icebreakers in Texas. The cutter returned to its Alameda home port after covering more than 23,000 nautical miles.
Why it matters
The patrol underscores growing U.S. and Canadian focus on Arctic security and monitoring of foreign vessels in a strategically sensitive region.
