Eight suicide attempts among sailors assigned to the USS Abraham Lincoln carrier strike group have raised questions about the mental health of US military personnel serving during the war with Iran.
The US Navy disclosed the incidents in information provided to a senator, according to CNN, bringing renewed attention to the mental health challenges facing sailors during extended deployments.
The reported attempts concern personnel across the carrier strike group, rather than necessarily occurring aboard the aircraft carrier itself.
The disclosure raises questions about the support available to service members during prolonged deployments, particularly those serving in combat conditions far from home.
It also highlights the importance of distinguishing between reported suicide attempts, confirmed deaths and the wider mental health challenges facing the US armed forces.
Navy Confirms Eight Suicide Attempts During Extended Deployment
Acting Navy Secretary Hung Cao confirmed the eight attempts in a letter dated 22 September to Senator Kirsten Gillibrand, a member of the Senate Armed Services Committee.
According to CNN's report, the incidents occurred during a deployment involving approximately 6,000 to 7,000 sailors across several warships, while Cao confirmed that no service members had died by suicide during the deployment.
The carrier remained at sea for more than six months without a port visit while conducting a high rate of combat operations against Iran.
A US military official told CNN that recent carrier strike group deployments had typically recorded one or two suicide attempts a year, while describing the pressures of combat operations, constant alerts and the absence of port visits as unusually demanding.
CNN cited the latest available Pentagon figures for additional context. In 2024, the Navy recorded 356 suicide attempts among approximately 337,000 active-duty sailors, with CNN reporting that the number of attempts in the Lincoln strike group was roughly consistent with the Navy-wide rate.
Sailors Report Difficult Conditions Aboard Uss Abraham Lincoln
The disclosure follows earlier reports of sailors attempting to jump overboard during the deployment. CNN previously reported that two sailors, including one assigned to the aircraft carrier, went overboard in separate incidents, and both were rescued.
Cao confirmed that a sailor assigned to the carrier's air wing went overboard in early August and received medical treatment after being recovered. Another sailor was stopped by shipmates while attempting to go overboard in March.
A crew member also described low morale, limited access to basic amenities and uncertainty about when they would return home. One sailor told CNN that toilets and drinking fountains were frequently unavailable, while hot water was sometimes lacking.
The Navy previously said it had not observed an increase in suicidal ideation or suicide attempts aboard the aircraft carrier. That earlier statement concerned the aircraft carrier itself, while Cao's subsequent disclosure covered the wider strike group.
What Mental Health Support Was Available to Sailors?
Cao's letter detailed the mental health resources deployed with the Lincoln, including five chaplains, a psychologist, a clinical social worker, three behavioral health technicians and one embedded integrated prevention counselor. An expeditionary facility dog was also available to support personnel.
However, a 2025 Department of Defense inspector general review identified shortcomings in the Navy's suicide prevention procedures.
The review found that the Navy faced challenges ensuring commanding officers had properly designed crisis response plans, with some plans lacking required elements, including local resources and contact information and a Sailor Assistance and Intercept for Life reporting requirement.
Inspectors also recommended assigning responsibility for oversight and annual reporting on Navy commands' compliance with crisis response plan requirements. The recommendations formed part of the inspector general's review of the Navy's efforts to prevent and respond to suicide-related incidents.
USS Abraham Lincoln's Return Raises Questions About Deployment Pressures
The Lincoln left the Middle East in August and was expected to return to its home port in San Diego in the weeks following the disclosure. The carrier's extended deployment has brought renewed attention to the demands placed on sailors during sustained military operations.
The eight reported attempts do not, by themselves, establish that combat operations or deployment length caused the incidents. Nevertheless, the disclosure provides Congress with additional information as lawmakers examine the conditions facing deployed personnel and the mental health support available to them.
The Navy's response to those concerns will remain relevant as the service prepares crews for future extended deployments.
