Trump says U.S. is sending hospital ship to Greenland despite shipyard repairs

President Donald Trump posted on Truth Social that the United States is sending "a great hospital boat to Greenland" and declared "It’s on the way!!!" while saying the move was "working with the fantastic Governor of Louisiana, Jeff Landry." The post was accompanied by a visual of the USNS Mercy and prompted immediate operational and diplomatic questions after officials said the two U.S. hospital ships are undergoing maintenance in an Alabama shipyard.

The two vessels that provide U.S. afloat medical capacity, USNS Mercy and USNS Comfort, each measure 894 feet and displace roughly 69,552 tons. The Mercy is a 1,000-bed hospital ship. As reported from shipyard photographs and maintenance schedules, Mercy has been in drydock at the Alabama Shipyard in Mobile since July 2025 and remained in drydock into late January 2026. When the Mercy is in reduced operating status at its San Diego berth it maintains a skeleton crew of about eight officers, 53 enlisted personnel and 15 civilian mariners and can be activated within five days under normal conditions. Both ships can accommodate up to 1,200 military personnel plus civilian mariners when fully mobilized.

The logistical picture is stark. A ship in drydock requires significant work before sea trials and deployment, and commanders must coordinate medical staffing, underway logistics and international port clearances for operations in Greenland. The White House post named Governor Jeff Landry as a partner in the effort; Landry has been designated as a special envoy to Greenland, a role the administration says involves Arctic engagement. The announcement did not include which ship would be tasked, a departure timetable, or which U.S. agency is coordinating the movement.

Denmark, which is responsible for Greenland’s foreign and defense policy, said it had not been told a ship was inbound. Danish Defense Minister Troels Lund Poulsen told public broadcaster DR that Danish authorities "had not been informed that the ship was on its way." Greenlandic officials likewise have not publicly confirmed a formal request for U.S. aid; one Greenlandic politician in the Danish parliament warned on social media that the proposal would not address systemic needs. Aaja Chemnitz wrote on Facebook, "Donald Trump wants to send a poorly maintained hospital ship to Greenland. It seems rather desperate and does not contribute to the permanent and sustainable strengthening of the healthcare system that we need."

There is narrow evidence of recent medical activity in Greenlandian waters: Denmark’s Joint Arctic Command reported it evacuated a U.S. submariner for urgent treatment approximately seven nautical miles off Nuuk and transferred the patient to a Nuuk hospital after retrieval by a Danish Seahawk helicopter. That evacuation underscores the practical challenges of delivering acute care across Greenland’s remote, maritime environment, but it does not amount to a public acknowledgement from Greenland’s government of a wider health crisis requiring a foreign hospital ship.

The announcement raises immediate questions officials must answer: which vessel is being tasked, whether a Navy ship can be made seaworthy in time, whether Greenland and Denmark have consented, and what medical mission the ship would perform beyond emergency care. For residents of Greenland the episode highlights a longer debate over sustainable health system capacity in the Arctic; for NATO partners the move may carry strategic signaling about U.S. presence in the region. Pentagon, Navy and White House confirmation of the ship's status and diplomatic clearance remain outstanding.
