The top US military commander in the Middle East, Admiral Brad Cooper, has visited the USS Abraham Lincoln aircraft carrier and praised its crew as "awe-inspiring," while acknowledging the extraordinary strain of a deployment that has kept the ship's 5,000 sailors and Marines at sea for more than 240 consecutive days — one of the longest uninterrupted deployments in modern US naval history.

Cooper, who heads US Central Command, said in a statement on Sunday that the Lincoln has "among the lowest number of cases related to mental health" of the Navy's 11 active aircraft carriers, and praised the ship's leadership for making mental health and crew resilience a priority. At the same time, he acknowledged the human cost of such extended service. "This doesn't mean that all is perfect," he said. "Service at sea for long periods isn't for everyone. It is uniquely challenging and tough, and every single one of us reacts to stressors in different ways."

The Lincoln has been operating in the Middle East since January, playing a central role in US military operations against Iran, including a blockade of Iranian ports. The deployment, originally set to end in May, has been extended multiple times — most recently indefinitely. Reports in the Military Times and Stars and Stripes described deteriorating conditions aboard the ship, including poor sanitation, broken plumbing and shortages of fresh food. Family members of sailors have publicly raised alarm about the mental health of their loved ones, and several crew members have reportedly attempted to jump overboard; one person reportedly entered the water on 3 August, though the US Navy declined to say whether it was a suicide attempt.

The reports have drawn sharp political reaction. Thirteen Democratic members of the Senate Armed Services Committee wrote to Defence Secretary Pete Hegseth on Saturday demanding answers about the lengthy deployment. Maryland Governor Wes Moore, a US Army veteran, called the reported conditions "heartbreaking" and said the president should show "more compassion." Hegseth last week called media reports of conditions on the ship "completely misrepresented," while President Donald Trump, asked Friday whether the Lincoln had been deployed too long, told reporters: "Not nearly long enough."

Relief is now on the way. The USS George Washington, a carrier previously stationed near Japan, is reportedly en route and expected to arrive in the region within about a week to relieve the Lincoln. Cooper described the deployment as one that "history will record as among the most operationally intense and consequential of the modern era" — words that, for sailors' families still waiting for their return, will likely carry a complicated weight.
