An Investigation into the Navy’s Response

On September 8, 2026, House Committee on Oversight and Accountability Chairman James Comer and Subcommittee on Military and Foreign Affairs Chairman William Timmons released “Unseen Impacts.” This report capped an investigation that began last year into the Navy’s Project Odin’s Eye, which purportedly delved into potential brain injury in naval aviators who routinely endure up to nine Gs, from catapult launches and high-G turns. Navy medical officials then reasoned, in Catch-22 fashion, that with no evidence a problem existed, no study was needed. Therefore, none was done.

This secret TOPGUN program wasn’t disclosed to Navy leadership until the New York Times exposed it in 2024. Now, after examining Project Odin’s Eye, investigators have concluded that the program’s “research” wasn’t TRUE research.  Based on this new information, the Committee and Subcommittee are now urging Congress to mandate a comprehensive long-term aviator brain health study.

Pentagon Started Tracking Blast Injuries Then Ran Out of People

The Department of Defense launched brain-health monitoring for troops exposed to weapons blasts. However, a federal watchdog report released August 18, 2026 found that the DoD lacks the staff, technology, and funding to fully deliver on it.

The DoD is highly aware, and the US Government Accountability Office report GAO-26-107829 warns, that firing certain weapons exposes service members to blast overpressure waves, which “may cause problems such as headaches, memory loss, or traumatic brain injury.” As with similar brain injuries, these waves can then travel through the skull and cause micro-injuries in the brain. (In fiscal 2025, 198,161 recruits completed baseline cognitive assessments, and 86% of high-risk personnel were screened, though the Navy lagged at only 59%.) Additionally, the GAO recognizes that a shortage of industrial hygienists remains the “primary barrier” to tracking exposures.

Assistant Secretary of Defense for Health Affairs Keith Bass agreed with both GAO recommendations, noting DoD “estimates it will complete the actions for both recommendations by December 2026.”
