The aircraft carrier USS Abraham Lincoln arrived in Thailand on Wednesday, its first port call in more than eight months, ending a marathon stint at sea in the Middle East that raised concerns about the welfare of its crew.

The 100,000-ton ship departed San Diego last November, and when it returns to Southern California later this year it will have completed one of the longest deployments in US Navy history.

The Lincoln has set a modern-day record for consecutive days at sea during combat and blockade duty in the war with Iran, according to US Sen. Richard Blumenthal.

The extended deployment has led to morale problems amid supply shortages, and at least one possible suicide attempt among its crew of 5,000, CNN has reported.

Blumenthal, a Democrat from Connecticut and a member of the Armed Services Committee, wrote to Defense Secretary Pete Hegseth and the acting secretary of the Navy last month to express “serious concern” about the increasing length of deployments and demand answers about living conditions aboard the carrier.

“There have been widespread reports of shortages of basic supplies, water contamination, plumbing issues, deteriorating mental health, deck safety concerns,” aboard the ship, he said in the letter, as well as “disruptions in the mail system, which have caused many care packages in route to the ship to be lost in transit for months.”

Hegseth later said that conditions on the Lincoln had been “completely misrepresented” though he did not specify his concerns with the reporting.

US President Donald Trump, when asked about the lengthy deployment, dismissed concerns, saying it was “not nearly long enough.”

But soon after the reported problems aboard the carrier went public, the Pentagon announced the Japan-based carrier USS George Washington was being dispatched to the Middle East to replace the Lincoln.

It has since taken up station there along with the USS George H.W. Bush, keeping a two-carrier presence for the US Navy as hostilities continue with Iran.
