Congressional Report on Potential TBIs, Mental Health Risks in Naval Aviation

The following is “Unseen Impacts: An Investigation into the Navy’s Response to Potential Traumatic Brain Injury and Mental Health Risks in Naval Aviation” published on Sept. 8, 2026, by the House Committee on Oversight and Government Reform Subcommittee on Military and Foreign Affairs.

From the Report

Executive Summary

Following reporting by The New York Times about an epidemic of potential brain injuries in naval aviators contributing to suicide, the House Committee on Oversight and Government Reform launched an investigation to assess the Navy’s knowledge of and actions taken regarding this issue. The findings reveal a disconnect between growing concern and an apparent lack of meaningful study by the Navy on long-term neurological impacts of aviation. Naval aviators and flight officers (which include rear seat crew on an F/A-18) operate under extreme and repeated physical stress from aerial maneuvers and the sudden acceleration of aircraft carrier catapult launches. Yet, the Navy has not determined whether these activities contribute to cumulative brain injury.

Key Findings:

Top Navy officials were alerted to mental health concerns and suicides within the F/A18 community but the Navy has not initiated a formal investigation into possible neurological causes.

The Navy has not conducted a comprehensive study on cumulative injuries for naval aviators and flight officers.

The current healthcare system for naval aviators detects acute injuries but may miss long-term damage.

Medical policies are built to respond to identifiable incidents, not to track gradual, career-long brain stress.

Naval aviation culture discourages aviators from seeking mental healthcare.

Fear of losing flight status or damaging careers leads many to avoid care or underreport symptoms, obscuring the true scope of the issue.

The Navy internally attributed mental health issues primarily to operational stress rather than neurological injury.

The Navy is focused on managing stress, not understanding the physiology of it.

Internal efforts emphasize maintaining operational tempo and general mental health access, while failing to examine whether the physical demands of aviation are contributing to neurological harm.

Project Odin’s Eye is not being effectively used for aviators.

The Navy asserts that Project Odin’s Eye is not a research project or protocol and it does not generate the kind of long-term, population level data needed to assess chronic brain injury.

The Navy’s response to the Committee does not indicate that the program has been officially implemented in the naval aviation community at all.

The result is a system that is well-equipped to treat injuries once they are diagnosed, but poorly structured to understand or prevent risks developing over time. In effect, despite internal warnings and external reporting, the Navy has not taken the steps necessary to determine whether it is systematically exposing its aviators to long-term brain injury.
