The USCGC Healy, America’s largest icebreaker, was towed back to port after a mechanical failure in Washington state—sidelining it from the Arctic for the near future.

The United States Coast Guard’s largest icebreaker, USCGC Healy (WAGB-20), isn’t breaking ice right now—and it won’t be for a while.

The icebreaker broke down earlier this month off the coast of Port Angeles, Washington. It was the second time in two years that the ship had to return to port to undergo major repairs, leaving the US spread thin with icebreakers even as tensions are increasing in the High North.

What Breaks an Icebreaker?

USCGC Healy was reportedly conducting sea trials at speeds exceeding 20 knots (23 mph) when an undisclosed mishap occurred on the ship. The icebreaker dropped in speed to just 2 knots (2.3 mph), and was unable to return to port under its own power.

The latest mechanical issues were serious enough that tugs were forced to tow the Healy back into port.

“The crew of Coast Guard Cutter Healy acted with speed and skill in responding to this casualty,” said Admiral Kevin E. Lunday, commandant of the Coast Guard. “While the Coast Guard remains underway and on mission in the Arctic, this casualty underscores the vital importance of President Trump’s vision to rapidly build and deliver a modern icebreaker fleet. The United States is an Arctic nation with enduring security, economic, and strategic interests in the region. The Nation needs a highly capable icebreaking fleet operated by the Coast Guard to ensure year-round access to the region to protect our northern border in Alaska and maritime approaches in the Arctic.”

America’s Biggest Icebreaker Just Can’t Catch a Break

The Healy previously suffered a propulsion motor fire during a deployment to the Arctic in 2020, which resulted in its patrol being canceled. It suffered another fire in August 2024, cutting that deployment short as well. Following both incidents, the icebreaker was sidelined for extended periods.

What makes this particular breakdown of the medium icebreaker all the more intriguing is that it comes after it had just completed a six-month repair period at the Vigor shipyard in Portland, Oregon, and was undergoing sea trials in advance of a planned patrol.

It is unclear how serious the issues are with WAGB-20, but it is expected that major repairs are needed, which could further sideline the vessel for several more months.

“The Coast Guard will provide additional information regarding the casualty aboard CGC Healy as it becomes available,” the service announced.

Healy Will Be Absent from US-China Showdown in the Arctic

This is arguably the worst time for the US Coast Guard to be without the USCGC Healy, as the service’s Legend-class cutter USCGC Munro (WMSL-755) has been monitoring the movement of a pair of Chinese Arctic icebreakers/research vessels, the Xue Long (Chinese for “Snow Dragon”) and the Xue Long 2.

Last week, the two Chinese ships were tracked passing through the United States exclusive economic zone (EEZ) and onto the US extended continental shelf (ECS) in the Bering Sea. The EEZ is a nation’s maritime area that extends up to 200 nautical miles from the coast, and the ECS includes the seabed and subsoil beyond a country’s standard EEZ.

“Munro’s efforts advanced Operation Frontier Sentinel, which is designed to protect American sovereign rights, ensure consistency with international law, and position the Coast Guard to rapidly respond to any detected malign activity. In recent years, the Coast Guard has observed heightened activity in the US Arctic and anticipates continued and increased presence in the region this summer,” the Coast Guard explained.

It was a year ago that USCGC Healy monitored the movements of another Chinese-flagged vessel and a Liberia-flagged ship believed to be operated by Beijing off the coast of Alaska.

Despite the fact that China isn’t an Arctic nation, it has dubbed itself a “near-Arctic power,” justifying the construction of icebreakers, and identified potential shipping routes in the High North as an extension of its “Silk Road Economic Belt” and “Maritime Silk Road” initiatives.

The US Coast Guard operates just three icebreakers, including a former oilfield supply ship and icebreaking offshore tug that was re-commissioned last year as the USCGC Storis (WAGB-21). The US Coast Guard, which is under the domain of the Department of Homeland Security (DHS) in peacetime, bought the Storis—formerly known as the tug Aiviq—as a stopgap as it awaits the arrival of the first Polar Security Cutter, the future USCGC Polar Sentinel (PSC-1), which is now being built by Bollinger Shipyards in Lockport, Louisiana, and is scheduled for delivery in 2028.

In addition, the Coast Guard is set to acquire the first two of a planned fleet of 11 Arctic Security Cutters (ASC) from NATO ally Finland by the end of the decade. The two medium-weight “three-season” icebreakers are now being built by Rauma Marine Constructions at the Helsinki Shipyard in Finland, with three more to be produced under license for the Coast Guard by Texas-based Davie Defense. Two others will be built in Finland, and four by Bollinger Shipyards, the USCG announced earlier in July.

“America’s future in the Arctic demands strength, capability, and resolve,” said Secretary of Homeland Security Markwayne Mullin. “I want to thank President Trump for his bold leadership and vision in directing this critical investment that made these icebreakers possible. These cutters will deliver the enduring operational capability our Nation needs to defend our sovereignty, deter adversaries, and safeguard vital resources for the American people.”
