Eight sailors assigned to US carrier group that fought in Iran war attempted suicide, Navy secretary tells Congress

By Zachary Cohen, CNN

(CNN) — Eight US Navy personnel assigned to the USS Abraham Lincoln carrier strike group attempted suicide during a period that included when the ships undertook combat operations against Iran and the carrier set a modern record for its time at sea, according to a letter from the service’s acting secretary, which was obtained by CNN.

Acting Navy Secretary Hung Cao revealed the number, which has not been previously reported and covers crew members from several ships that travel together, including the carrier, in written responses to questions posed by Sen. Kirsten Gillibrand about the morale and mental health of the USS Abraham Lincoln’s crew. Cao wrote that no service members had killed themselves during the deployment.

The rate of suicide attempts among the Lincoln strike group’s sailors was roughly consistent with that of the entire active duty Navy in 2024, the most recent year for which the Pentagon has released suicide data. That year, the Navy saw 356 suicide attempts among its estimated 337,000 active duty sailors.

“Since the beginning of Lincoln’s deployment, there have been a total of eight suicide attempts across the strike group,” Cao wrote to Gillibrand, a Democrat and member of the Senate Armed Services, in a letter dated Tuesday. “This number includes the Lincoln crew and sailors from the carrier airwing, strike group and destroyer squadron staff, escorting destroyers and all embarked aviation squadrons.”

Between 6,000 and 7,000 US Navy sailors were deployed as part of the Lincoln strike group across roughly a half dozen ships — with the carrier kept out of port for over six months while conducting a high rate of combat operations against Iran.

“Eight attempted suicides is incredibly high,” one US military official told CNN, noting recent carrier strike group deployments have had one or two per year. “The strain of combat ops is much higher than normal deployments. No port calls, constant alerts, etc.”

The Navy did not respond ahead of publication to a request for comment about the letter.

The Lincoln deployed with various mental health resources onboard, including five chaplains, one embedded integrated prevention counselor, one psychologist, one clinical social worker, three behavioral health technicians and one expeditionary facility dog, according to Cao’s letter.

CNN previously reported that two sailors assigned to the Lincoln strike group, one from the carrier and one from another ship, had jumped overboard in recent months. Both were rescued, US officials said. Others were prevented from jumping, according to reports from the Navy Times and Stars and Stripes.

In his letter to Gillibrand, Cao also confirmed that a sailor assigned to the airwing went overboard from the ship in early August but was “quickly recovered” and treated by the Lincoln’s medical department. “Additionally, one sailor attempted to go overboard in March and was stopped by his shipmates. That sailor was also provided immediate medical care and subsequently returned to homeport.”

The Navy previously said in a statement to CNN, “We have not observed an increase in suicidal ideations or attempts aboard the ship. We take every service member’s well-being seriously and have religious, medical and mental health professionals available to assess and address concerns as they arise.”

A US official also previously told CNN that the Navy does not believe there is a correlation between deployment length and thoughts of self-harm, and that man overboard incidents are not unique to this group.

A crew member serving on the Lincoln previously described to CNN that morale on the carrier was very low and said they had heard repeatedly about suicidal ideation by fellow crew members. And there were regular strains on essential amenities — toilets and water fountains around the ship frequently closed, and hot water was often unavailable, the crew member said.

“Everyday we wake up and listen to our captain speak, we are desperately hoping and anxious for updates on our return,” the crew member, speaking before the ship had been ordered to return to its home port in San Diego, told CNN. The ship left the Middle East in August and is expected back in San Diego in the coming weeks.

Other sailors aboard the Lincoln who spoke with CNN described conditions unlike their prior deployments, largely due to the combat that has kept the carrier from making stops at friendly ports. Ships can take on new supplies and allow their sailors to rest and relax during those port calls.
