The ACES Act of 2025 directs the Secretary of Veterans Affairs to seek an agreement with the National Academies of Sciences, Engineering, and Medicine to conduct a study on cancer prevalence and mortality among individuals who served as active‑duty fixed‑wing aircrew. The study must identify military occupational exposures, review scientific literature linking those exposures to specific cancers, and estimate prevalence and mortality using available administrative and mortality data.
This study creates an authoritative, congressionally‑requested evidence base that could inform VA adjudication policy, potential presumptions of service connection, DoD occupational health practices, and future research priorities. The bill also builds procedural deadlines and reporting duties into the VA’s contracting process to accelerate study initiation and keep Congressional veterans’ committees informed if the VA misses those milestones.
At a Glance
What It Does
The bill requires the Secretary of Veterans Affairs to seek, within 30 days of enactment, an agreement with the National Academies to study cancer prevalence and mortality among covered aircrew and to finalize that agreement within set deadlines. The study must (1) identify occupation‑related exposures, (2) review associations between those exposures and a specified list of cancers, and (3) estimate prevalence and mortality using VA, DoD, and national mortality data plus prior studies.
Who It Affects
Primary populations are former and current active‑duty fixed‑wing aircrew across Army, Navy, Air Force, and Marine Corps, as well as their survivors. Operationally affected organizations include the Department of Veterans Affairs (which must execute the agreement and provide data), the Department of Defense and individual services (data contributors), the National Academies (study contractor), and Congressional veterans’ committees (report recipients).
Why It Matters
The study targets a defined occupational group with long‑standing exposure concerns and sparse consolidated evidence. Its findings could underpin VA rulemaking or statutory presumptions, change DoD exposure monitoring, and guide resource allocation for veteran care and surveillance.

What This Bill Actually Does
The ACES Act tasks the VA with initiating a National Academies study focused on cancer among active‑duty fixed‑wing aircrew. Rather than directing specific policy changes, the bill creates an independent scientific assessment: the Academies are to catalog occupational exposures tied to aircrew roles, review peer‑reviewed and grey literature for links between those exposures and cancer types, and then estimate how common those cancers are and how many deaths they cause in this population.
The emphasis is on assembling and analyzing existing data sources rather than on new primary data collection.
The bill enumerates cancers for review—including brain, colorectal, kidney, lung, melanoma, non‑Hodgkin lymphoma, pancreatic, prostate, testicular, thyroid, and bladder cancers—and allows the Secretary, in consultation with the Academies, to include others deemed appropriate. To estimate prevalence and mortality, the Academies must use available administrative health records from VA and DoD, the National Death Index, and prior studies referenced in law (notably the section 750 study in the FY2021 NDAA), so their work will hinge on linkage and quality of those datasets.Procedurally, the statute accelerates contracting: the VA must seek the agreement quickly after enactment and finalize terms within a specified window after beginning negotiations; if the VA misses the deadline it must explain the delay to the Congressional veterans’ committees and provide progress briefings every 60 days thereafter.
At completion, the Academies deliver a report to the Secretary and the two veterans’ committees. The bill stops short of mandating follow‑on action, but the report is positioned to inform benefit decisions, surveillance programs, and DoD/VA occupational health interventions.Because the study relies on existing administrative sources and an external scientific body, the likely output is an evidence synthesis and epidemiologic assessment rather than immediate causal determinations for individual claims.
That design gives the Academies latitude to highlight data gaps and recommend new surveillance or research, which may in turn drive future legislative or administrative remedies.
The Five Things You Need to Know
The Secretary of Veterans Affairs must seek an agreement with the National Academies within 30 days of enactment to conduct the study.
The VA must finalize that agreement within 60 days after it begins negotiations; if it fails, the VA must report reasons and an estimated finalization date to the Senate and House veterans’ committees and brief them every 60 days thereafter.
The study must identify military occupational exposures for covered aircrew and review associations between those exposures and a defined list of cancers (including brain, lung, prostate, melanoma, non‑Hodgkin lymphoma, and others).
To estimate prevalence and mortality, the Academies must use available data sources: VA and DoD administrative health records, the National Death Index, and the FY2021 NDAA Section 750 study as relevant inputs.
The final product is a National Academies report delivered to the Secretary and the veterans’ committees; the statute does not itself create presumptions or benefits but supplies evidence that could prompt such changes.
Section-by-Section Breakdown
Every bill we cover gets an analysis of its key sections.
Short title
Declares the law’s citation as the 'ACES Act of 2025.' This is purely titular but is useful for referencing the act in future legislation, reports, and agency actions.
Agreement with the National Academies; deadlines and reporting
Requires the Secretary of Veterans Affairs to seek an agreement with the National Academies within 30 days of enactment and to finalize that agreement within 60 days of entering negotiations. If the VA fails to finalize, the section compels the Secretary to submit an explanation and a new timeline to the Senate and House veterans’ committees and to provide progress briefings at least every 60 days. Practically, this creates enforceable transparency obligations on the VA’s procurement and engagement timeline, increasing Congressional visibility into contracting progress.
Scope and methods of the study
Directs the National Academies to (1) identify exposures linked to aircrew occupations, (2) review literature tying those exposures to overall cancer morbidity and mortality and to specific cancer types, and (3) estimate prevalence and mortality among covered individuals using available datasets. This frames the Academies’ mandate as an evidence synthesis and epidemiologic assessment relying primarily on secondary data analysis and literature review rather than new cohort establishment.
Report delivery
Requires the National Academies to submit a final report to the Secretary of Veterans Affairs and to the Senate and House veterans’ committees at the study’s conclusion. The statute specifies recipients but does not set a hard calendar deadline for report delivery, leaving the study timeline to be set in the agreement and by the Academies’ normal review processes.
Definition of covered individuals
Defines 'covered individual' as anyone who served on active duty in the Army, Navy, Air Force, or Marine Corps as a fixed‑wing aircrew member—explicitly listing pilots, navigators, weapons systems operators, aircraft system operators, and other crew who regularly flew in fixed‑wing aircraft. That definition bounds the study population and excludes rotary‑wing, reservists not on active duty, and civilians unless they meet the stated criteria.

Every bill creates winners and losers. Here's who stands to gain and who bears the cost.
Who Benefits
- Former and current active‑duty fixed‑wing aircrew and their survivors — the study provides a consolidated assessment of cancer risks that could underpin future VA presumptions or targeted screening and care.
- VA policymakers and adjudicators — the Academies’ evidence synthesis offers an independent basis for benefit policy decisions and could reduce scientific uncertainty in claims adjudication.
- Occupational health and epidemiology researchers — the report will identify data gaps and recommend research priorities, guiding future studies and funding.
- Department of Defense medical and safety offices — findings may inform exposure mitigation, monitoring practices, and preventive measures across services.
- Congressional veterans’ committees and staff — the bill supplies a vetted technical product to inform oversight, legislation, and appropriations decisions related to veteran health.
Who Bears the Cost
- Department of Veterans Affairs — administrative burden and potential costs to negotiate, manage, and provide data support for the study; if the study prompts benefit changes, VA may face larger fiscal obligations.
- Department of Defense and individual services — required to make administrative and medical records available for linkage and analysis, which consumes staff time and may require data standardization work.
- National Academies — responsible for conducting a substantial synthesis and analysis within the contract terms; while expert, the Academies will bear operational costs of convening panels and performing analyses (covered by the agreement funding).
- Congressional oversight staff — increased briefing and reporting obligations create recurring workload for committee staff to track progress and assess implications.
- Potential federal budget — if the study leads to presumptive service connection or expanded benefits, the long‑term fiscal cost would fall on VA and the federal budget, not on the study itself.
Key Issues
The Core Tension
The central dilemma is urgency versus evidence: veterans and families seek timely recognition and benefits for suspected occupational cancers, but rigorous epidemiologic conclusions require high‑quality linked data and careful causal assessment. The bill speeds the production of an independent scientific report, yet its reliance on existing administrative records and lack of guaranteed funding may delay clear answers — creating a situation where the demand for fast relief clashes with the time and resources needed for reliable science.
The statute creates a focused, evidence‑building mechanism but leaves important implementation details unresolved. It requires the VA to 'seek to enter into an agreement' and to finalize negotiations within a set window, but it does not appropriate funds or specify the budget for the National Academies contract; procurement and funding must be resolved administratively.
That gap means the speed and scope of the study will depend on available VA appropriations or reprogramming, and funding constraints could delay or narrow the Academies’ work despite the statutory deadlines.
The bill also hinges on secondary data sources—VA and DoD administrative records, the National Death Index, and prior statutory studies—which vary in completeness, coding consistency, and linkage feasibility. Exposures relevant to aircrew (e.g., in‑flight chemical exposures, fuel/solvent contact, radiation, or cabin environment factors) are often poorly measured in administrative datasets, so the Academies may conclude that data gaps prevent definitive causal inferences.
That outcome could produce recommendations for more surveillance rather than immediate policy fixes. Finally, the statute narrows the population to fixed‑wing active‑duty aircrew; rotary‑wing crew, reservists, civilians, or those with mixed service records are excluded, which limits the generalizability of findings and could leave other exposed groups without a parallel evidence base.
