The U.S. Navy hospital ship USNS Mercy has reached Vigor's shipyard in Portland, Oregon, as confirmed by the latest Automatic Identification System (AIS) data. This arrival ends weeks of speculation about its planned deployment to Greenland.
Recent AIS signals indicate that the 1,000-bed hospital ship traveled north along the U.S. West Coast and entered the Columbia River, arriving on March 19, which aligns with its scheduled shipyard availability at Vigor's Swan Island shipyard.
This arrival strongly suggests that Mercy’s journey from the Gulf Coast through the Panama Canal was part of a planned move to the Pacific Northwest rather than an Arctic mission.
Mercy left Alabama Shipyard in Mobile in late February after completing repairs. The ship gained attention when President Donald Trump announced on social media that it was "on its way" to Greenland. This statement caused confusion among officials and led Greenland's leaders to clarify that no such mission had been requested.
Afterwards, AIS tracking pointed to a different course. Following its transit through the Panama Canal in early March, the ship was seen steadily moving north along the Pacific coast, consistent with plans for maintenance in Portland. “Nobody expected the Northwest Passage approach,” one social media user humorously noted.
The ship is now set for a multi-month overhaul at Vigor Industrial as part of a maintenance program costing around $90 million, which will keep it out of service for several months.
The timing of the ship's availability and operational limitations had already raised doubts about a potential Greenland mission. Mercy is not strengthened for ice and has never operated in Arctic conditions, where late-winter sea ice, icebergs, and limited port facilities would present significant challenges for such a large vessel.
The ship's arrival in Portland highlights the disconnect between President Trump’s announcements and the realities on the ground, with AIS data providing a clear, real-time account of the ship’s actual movements.
USNS Mercy, managed by the U.S. Navy’s Military Sealift Command, is one of two hospital ships in the fleet, capable of holding up to 1,000 patients and featuring 12 operating rooms when fully activated. Its sister ship, USNS Comfort, is also in Alabama undergoing maintenance.
