More than 5,000 sailors aboard the USS Abraham Lincoln, a US Navy aircraft carrier deployed in the Arabian Sea, are reportedly enduring deteriorating conditions after more than 250 days at sea — a stretch that lawmakers describe as a record for continuous days underway in recent American military history. Reports of food shortages, broken plumbing, water contamination, lost mail and serious mental health crises have prompted Democratic members of Congress to demand answers from the Pentagon, while Defence Secretary Pete Hegseth insists the accounts are "completely misrepresented."

The carrier left California in November for the South China Sea before being redirected to the Middle East ahead of US military operations against Iran, which began in February. Originally expected to return in May, the deployment has been extended multiple times with no end date announced — a situation that retired Dutch vice-admiral Ben Bekkering, who has experienced extended deployments himself, described as particularly damaging to morale. "If you keep extending without giving a new end date, that is very hard on the crew — and on those waiting at home," he said. Families of sailors gathered in San Diego last week to meet with Navy leadership, where accounts of a sailor going overboard — subsequently rescued by helicopter and transferred ashore for further care — provoked angry reactions when officials initially described the individual as doing "fine." Separately, military publications Stars & Stripes and Navy Times reported that multiple service members had considered or attempted to jump overboard, with one sailor's relative telling BBC News that their family member had lost 65 pounds (29kg) since deployment began. "He said, 'I'm dead tired. Dead,'" the relative recounted.

Under normal peacetime conditions, US Navy vessels typically visit a port every 45 days; during military operations, six months is considered a maximum. The Lincoln has been at sea for over 200 days without docking. Senator Richard Blumenthal, a Democrat on the Senate Armed Services Committee, wrote to Hegseth citing "shortages of basic supplies, water contamination, plumbing issues, deteriorating mental health, deck safety concerns and disruptions in the mail system." Fellow Democrat Ruben Gallego called for a congressional delegation to be allowed aboard to conduct oversight. A January 2025 study of nearly 1,000 sailors found that US Navy personnel suffer the highest rates of serious psychological distress of any military branch, citing noise, poor habitability and insufficient rest as key factors.

The Navy acknowledged that "traditional supply hubs" had been disrupted by combat operations and said it was prioritising deliveries in order: food, then hygiene items, then mail. Officials stated they had not identified an increase in reported suicidal ideation aboard the ship and confirmed access to chaplains, mental health professionals and medical staff. Hegseth, speaking to reporters in Panama, defended the deployment, saying the administration was doing everything possible to support the crew. On Thursday, multiple outlets reported that the USS George Washington is en route to the region to replace the Lincoln as part of a previously scheduled rotation — offering the prospect of relief, though no formal return date has been confirmed.

The episode highlights a broader question raised by lawmakers: whether the US Navy can sustain the operational pace now being demanded of its carrier force during an active conflict. Suicide remains a leading cause of death in the Navy and Marine Corps, and veterans overall face higher suicide rates than the general American population. With the Iran conflict continuing and the Lincoln still at sea, the pressure on its crew — and on military families back home — shows no immediate sign of easing.
