8 sailors in USS Abraham Lincoln strike group attempted suicide: NavyEight US Navy personnel assigned to the USS Abraham Lincoln carrier strike group attempted suicide during its lengthy deployment, including a period in which the group conducted combat operations against Iran, Acting Navy Secretary Hung Cao told Congress. Cao disclosed the number in a letter to Senator Kirsten Gillibr and of New York on Tuesday, responding to questions from the Democrat about the morale and mental health of sailors serving aboard the carrier and other ships in the strike group.
No service member died by suicide during the deployment, according to Cao's letter. The carrier strike group, which has been deployed since November, is now returning to the United States after an extended period at sea.
“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.” The carrier strike group included between 6,000 and 7,000 sailors deployed across roughly half a dozen ships.
The USS Abraham Lincoln itself remained out of port for more than six months while conducting a high tempo of combat operations against Iran. The number of attempts was roughly consistent with the rate recorded across the active-duty Navy in 2024, according to the data cited in the material.
The Navy recorded 356 suicide attempts that year among an estimated 337,000 active-duty sailors. “Eight attempted suicides is incredibly high,” the official said, adding that recent carrier strike group deployments had recorded one or two attempts per year.
“The strain of combat ops is much higher than normal deployments. No port calls, constant alerts, etc.”
Cao said the Lincoln strike group had multiple mental health and other support resources available to sailors throughout the deployment. According to Cao's letter, the resources included five chaplains, one embedded integrated prevention counsellor, one psychologist, one clinical social worker, three behavioural health technicians and one expeditionary facility dog.
The disclosure came after family members of sailors raised concerns about deteriorating mental health and difficult conditions aboard the carrier during its prolonged deployment. Cao's letter also confirmed incidents in which sailors went overboard or attempted to go overboard.
“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.”
