Coast Guard crews are monitoring vessels flying Chinese flags in the Arctic as border security remains a priority for the Trump administration. The effort is also strengthening maritime coordination between the United States and Canada across the remote northern region, as reported by Just The News.

During its latest mission, the crew of Coast Guard Cutter Munro, WMSL 755, spent nearly four months operating in the Coast Guard Arctic District. The deployment focused on controlling, securing, and defending the northernmost maritime approaches to the United States.

The crew also worked with international partners to strengthen regional defenses. Through Operation Frontier Sentinel, Cutter Munro monitored three Chinese research vessels operating in and around United States Arctic waters.

The Coast Guard said the monitoring was conducted to ensure that the vessels complied with international maritime law. By July, the crew had monitored two vessels flying Chinese flags, according to The Center Square.

“The Arctic is a demanding maritime environment that can test any crew and vessel,” Cutter Munro’s commanding officer, Capt. Adam Disque, said.

“We were proud to sustain U.S. presence in the region to safeguard our Arctic coastline and reinforce a rules-based order in the High North.”

Cutter Munro also participated in combined exercises with the Royal Canadian Navy. Those activities included joint maneuvering and shared awareness of maritime activity in polar waters, according to the Coast Guard.

Under Operation Tundra Merlin, the crew joined strategic Western Hemisphere defense operations alongside the United States Department of War and the Canadian Armed Forces. The operation tested homeland defense architecture across northern maritime corridors.

The participants integrated command and control networks while testing response readiness and operations across multiple domains. The work reflected a broader effort to coordinate military capabilities in the difficult Arctic environment.

“We also strengthened our enduring partnership with Canadian counterparts, advancing shared domain awareness and coordination across the remote region,” Disque said.

The cutter had another major assignment during the patrol. It served as the front-line guardian of Alaska’s $6 billion commercial fishing industry while operating in the Bering Sea.

Working with maritime law enforcement teams, the crew inspected commercial fishing vessels for compliance with federal safety regulations and fisheries laws. The Coast Guard said those enforcement efforts were intended to preserve vital fish stocks.

Cutter Munro recently returned to its home port at Base Alameda on Coast Guard Island following a 112 day Alaska patrol. The crew traveled more than 23,000 nautical miles across the Bering Sea and Arctic Ocean during the mission.

Base Alameda is one of the largest Coast Guard bases on the West Coast. It is located on an island in the Oakland Estuary between Oakland and Alameda, California.

The Arctic patrol is part of an expanded border security mission advanced by the Trump administration. The One Big Beautiful Bill Act provided a record $25 billion investment in the Coast Guard, according to the report.

Of that amount, $3.5 billion was awarded to the American subsidiary of Canadian Davie Defense to build polar ice cutters. Three of the cutters are being constructed in Texas.

American, Finnish, and Canadian leaders also formed the Icebreaker Collaboration Effort, known as the ICE Pact. The three nation initiative is designed to advance shipbuilding and Arctic defense, including work on the cutters being built in Texas.

Commissioned in 2017, Cutter Munro is one of four 418 foot Legend class national security cutters based in Alameda. The vessel was named for World War II hero Signalman 1st Class Douglas Munro of Washington state.

Munro was the only Coast Guard crewman to receive the Medal of Honor for heroism at Point Cruz, Guadalcanal, on Sept. 27, 1942. He was killed after rescuing nearly 500 Marines under heavy enemy fire.

In May 1943, President Franklin Delano Roosevelt presented the Medal of Honor to Munro’s parents, James and Edith Munro. A few hours later, Edith Munro took an oath and joined the Coast Guard.

She completed boot camp at age 48 and received a commission in the SPARS, the Coast Guard’s female branch. She managed the Coast Guard Barracks in Seattle and was discharged two years later with the rank of Lieutenant.
