Eight sailors attempted suicide while deployed with the USS Abraham Lincoln aircraft carrier strike group, which spent a record-setting uninterrupted time at sea supporting the Iran war, according to the Navy's top civilian leader.
Acting Navy Secretary Hung Cao provided the information to US Senator Kirsten Gillibrand in a letter dated Tuesday, local time, after the New York Democrat inquired last month about the strike group's crew.
The Lincoln's extended deployment drew international attention following reports of crew stress and poor mental health, as well as supply shortages, including food and hygiene products.
Eight attempts in a strike group of 6,000 sailors over 10 months is actually low, experts say. The Navy reported 356 suicide attempts across the service in 2024, while there were more than 1,500 attempts among all active-duty personnel that year, according to the latest annual report.
Doctor Harold Kudler, a former national lead for mental health services at the Department of Veterans Affairs and a retired VA psychiatrist, said the reported attempts were not the best measure for conditions on the Lincoln and its supporting destroyers, particularly with no additional details.
"But something happened to get those families upset. Something happened to raise concerns about the health and well-being of those troops," Dr Kudler said, referring to media reports that quoted sailors and their families.
"So we need to understand what that was because we don't need that to happen again."
Dr. Kudler said it could be challenging for troops counting down the days of their deployment to have it extended, and the Lincoln could be a learning opportunity for the Navy.
"Let's really do a serious look at what lessons have been learned and what we can do in the future," he said, "to ensure that these kinds of deployments, if they are necessary, are easier on the service members and the families".
Acting Navy secretary defends conditions
Senator Gillibrand asked Acting Navy Secretary Cao several questions focused on ship conditions, including the availability of mental health support, healthy food, and hygiene.
The senator also asked if there were any suicides.
"There have been no suicides on board during this deployment," Mr Cao wrote in the letter, which was obtained by The Associated Press and reported earlier by CNN.
"Since the beginning of Lincoln's deployment, there have been a total of eight suicide attempts across the strike group — this number includes the Lincoln crew and Sailors from the carrier wing, strike group and destroyer squadron staff, escorting destroyers, and all embarked aviation squadrons."
Mr Cao wrote that the carrier deployed with a psychologist, a clinical social worker, a counsellor, three behavioural health technicians and a therapy dog.
Mr Cao said the Lincoln maintained adequate food supplies, but because combat operations limited resupply opportunities, meal options were reduced from two to one for a short time.
However, he wrote that four nutritionally balanced meals were served daily.
Mr Cao acknowledged delays in scheduled resupply shipments but said the Navy prioritised the delivery of hygiene products and established a rotation to streamline distribution to different squadrons.
He also acknowledged piping failures on the carrier early in its deployment as well as temporary issues with desalination units.
Trump downplayed ship condition reports
US President Donald Trump had downplayed reports about conditions on the Lincoln, which left its home port in San Diego in November, arrived in the Middle East in January in support of operations against Iran, and spent a record-setting uninterrupted time at sea of more than 260 days.
The carrier and some of its supporting ships stopped in Thailand in early September on their way back home to California.
The Lincoln's commanding officer, Captain Dan Keeler, said then that the ship was heading home soon but may make further supply stops. He declined to say the exact date the strike group was expected back in the US.
Last month, Mr Trump called the nearly nine months at sea that the sailors endured a "good period of time" but added that "over the years, we've had them out there much longer".
Defense Secretary Pete Hegseth also said that conditions aboard the Lincoln were "completely misrepresented".
Senator slams 'deteriorating conditions'
Senator Gillibrand took aim at Trump and Hegseth in a statement released this week in response to Mr Cao's letter.
"What Trump and Secretary Hegseth dismissed as 'fake news' turned out to be serious and deteriorating conditions for our service members," she stated.
"Our troops and their families make immense sacrifices every single day, yet the president dismissed them with open disrespect.
Extended deployments of carriers wear on service members who are away from home for long periods and increase strain on the ship and its equipment.
The Navy is enforcing a blockade on Iranian ports in the Strait of Hormuz, and the Trump administration has offered no clarity on how it intends to wind down the nearly seven-month-old war.
