HitchAI read

This activity requests $84.7M in FY2027, 11% of project 377 — a restart, funded in FY2025 and zeroed in FY2026. The R-2A exhibit describes it across FY2025–FY2027, including what the FY2027 money is planned to buy.

Restart

This activity was funded in FY2025 ($56.2M), zeroed in FY2026, and requests $84.7M again in FY2027. A restart has an incumbent and a new start does not; with a zero current year there is no percentage to quote, which is why it appears in no growth ranking.

What the FY2027 request buys

Verbatim from the R-2A exhibit for project 377 of PE 0603375D8Z. This is the budget justification's own description of work that has not happened yet — the one thing no other level of the budget carries.

FY2027 planned work

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 areas, and together will provide protection against this asymmetric threat and reestablish deterrence by minimizing threat impacts.

FY2026 to FY2027 change

The increase of $28.472 million between FY 2026 and FY 2027 is due to an internal funding realignment within the Critical Technologies portfolio. This funding increase supports high-priority DoW research for AHI.

Before the request year

FY2025: what came before

Prior-year accomplishments and current-year plans from the same exhibit. Context for the FY2027 plan, not a series — an activity partitions its project exactly in the request year, but can under-cover it in earlier years.

FY2025 accomplishments

Using equipment and instrumentation purchased and the research capabilities developed in FY 2024, perform novel research and evaluate the scientific and physics basis for certain hypotheses related to plausible mechanisms associated with the AHI phenomenon. Develop enhanced bioeffects testing and continue development and testing of countermeasures.

Money

Three years, and no five-year plan

An R-2A activity publishes the prior year, the current year and the budget year. The FYDP outyears exist at project and program-element level and are deliberately absent here rather than inferred. Estimate types are colored and never summed into one figure.

This activity is 11% of project 377's FY2027 request and 8.6% of PE 0603375D8Z's. In the request year the activities under a project sum to it exactly; in the current year they under-cover it in about 9% of cases, so an activity's delta can legitimately exceed its parent's and the two must not be compared row to row.
