The Navy has failed to determine whether the punishing physical demands of naval aviation are placing pilots at greater risk of traumatic brain injuries and lasting head trauma.
That dangerous knowledge gap leaves the service poorly equipped to protect, diagnose, or treat aviators suffering from possible cumulative damage.
Those findings were published Tuesday in a report from the military subcommittee of the House Committee on Oversight and Government Reform.
Investigators identified serious deficiencies in research, medical care, and the aviation culture surrounding treatment for brain injuries and related mental health problems.
The investigation followed mounting concerns from whistleblowers and reporting by The New York Times about several suicides involving F/A-18 pilots.
Those cases raised questions about whether repeated exposure to violent launches, high speed combat maneuvers, and intense gravitational forces could cause lasting neurological harm.
“The Navy is confronting a risk it has not fully chosen to understand,” the report states. “Despite credible warnings, external reporting, and internal awareness, the Navy has yet to determine whether the very conditions that define naval aviation may also be causing long-term harm to the pilots who endure them.”
In 2024, Lt. Cmdr. Dr. Richard W. Lang of the Department of Orthopedic Surgery at Naval Medical Center San Diego acknowledged several “high-profile” suicides involving senior, combat experienced F-18 pilots.
His independent research identified common stressors such as relationship problems, substance abuse, and mental health conditions that worsened without treatment.
Lang’s study circulated among naval aviation leaders, including Capt. Mike Burks, program manager for the F/A 18 and EA 18G programs.
Burks urged the aeromedical community to “take ownership of the issue,” but the House committee found no “consensus” about what meaningful action should follow.
That bureaucratic paralysis is especially troubling because pilots are not operating in ordinary workplace conditions.
They routinely endure catapult launches, arrested landings, high gravitational forces, oxygen related incidents, cognitive strain, and repeated physical stress that can accumulate throughout years of service.
The committee described the Navy’s failure to dedicate resources to examining those combined dangers as a “strategic oversight.” Of 127 Navy medical research projects involving aviators, none evaluated cumulative neurological danger across an aviator’s full career.
Instead, those projects examined individual problems such as hypoxia, spatial disorientation, or cognitive fatigue.
None specifically considered “cumulative brain injury risk over time,” leaving commanders and physicians without a complete picture of what repeated exposure may be doing to pilots.
“The absence of evidence is therefore more indicative of a lack of targeted study rather than a credible conclusion of an absence of risk,” the report said. In plain English, the Navy cannot claim the danger is absent when it has not seriously looked for it.
The Navy does operate Project Odin’s Eye, which studies certain brain health risks involving aviators.
However, the committee found that effort narrowly focused and designed to identify performance concerns among a limited number of special operators, not to conduct broad, long term assessments across naval aviation.
Institutional blind spots are only part of the problem. Investigators also described a “self-reinforcing system” in which aviators avoid mental health care because they fear cultural stigma, damage to their careers, or the loss of flight status.
An April 2026 study of naval aviators found that nearly 72 percent reported avoiding medical care.
Another 42 percent admitted withholding information because they worried medical disclosure could ground them, a concern also reported among Army aviators and civilian commercial pilots.
The committee concluded that the Navy’s understanding of aviator mental health remains “incomplete.”
Rather than thoroughly investigating physical causes of neurological injury, the service has often concentrated on managing operational stress through bonuses, leave, and other incentives.
“This is not an either-or issue. Operational stress is clearly a concern,” the report said.
“However, the Navy’s own documents show that it has not seriously examined whether cumulative exposure to high G-forces and other physiological stressors could also be contributing to long-term mental health outcomes.”
Naval aviators accept extraordinary danger as part of defending the country, but they should not be forced to gamble blindly with their brain health.
Congress has now put the failure on paper, and Navy leaders have little excuse left for more studies that examine everything except the central threat.
