## Summary

Project 377 — Anomalous Incidents Research requests $786.7M in FY2027, 80% of the $982.7M requested for program element 0603375D8Z — a restart: funded in FY2025, zeroed in FY2026, funded again now. 3 R-2A activities decompose the request, 2 new and 1 restarted this cycle.

## What project 377 buys

The Anomalous Health Incidents (AHI) Cross Functional Team (CFT) was established in 2022 using the authority provided pursuant to section 911(c) of the National Defense Authorization Act for Fiscal Year 2017 (Public Law 114–328; 10 U.S.C. 111 note) to conduct AHI research. This program was redirected to synchronize research efforts in coordination with the CFT as mandated by the Department in a memo from the Secretary of Defense in 2022. Previously referred to as Havanna Syndrome or as an Unconventional Brain Injury, AHI is the term used to describe a group of sudden symptoms that occur after an unexplained sensory event or events that are not associated with a history of head trauma. Possible symptoms associated with an AHI event may include, but are not limited to: auditory symptoms, vestibular problems, cognitive decline, head pressure, headache, hearing changes, memory problems, nausea, dizziness, and insomnia. AHI events have been reported by several Department of War (DOW) and Federal Agency personnel since 2016. This program supports the Department's research and development efforts to address causal mechanisms underlying AHI. The program focuses on independent validation of current bioeffects research and developing solutions for detection, protection, and mitigation to safeguard the DoW workforce against these threats. While mitigating AHI remains the highest priority, the program's strategy extends to address the broader threat of non-kinetic, anti-personnel capabilities.

### Classified Programs — NEW START

**FY2027 planned work.** See higher classification

**FY2026 to FY2027 change.** See higher classification

### Anomalous Health Incidents (AHI) — RESTART

The requested funding will enable the continuation, maturation, and validation of numerous research lines of effort that are building on work accomplished in FY 2024, FY 2025, and FY 2026 to safeguard our service members against AHI. The efforts work across medical research, detection, sensing, countermeasures, and attribution technical…

### C-5 Beyond Line-of-Sight Capability — NEW START

**FY2027 planned work.** Improve communications capabilities via installment of digital high frequency (HF) mesh with cross banding capability to mobile and ground stations for beyond line of sight (BLOS) capability. Plans include: - Development of roll on roll off communications kits - Integration of kits onto aircraft - Training for service operators/maintainers

**FY2026 to FY2027 change.** The increase in FY 2027 request is due to an investment in the development and demonstration of HF mesh to provide BLOS communications.
