What the FY2027 request buys
Verbatim from the R-2A exhibit for project 613002 of PE 0601102F. 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.
- Continue investigating the characterization, modeling, and exploitation of interactions between the unsteady aerodynamic flow field and the dynamic air vehicle structure to enable enhanced performance in next-generation Department of the Air Force systems. - Continue to explore the synergy gained from an interdisciplinary integration of fluid mechanics, high-performance structures, and thermodynamics research.
FY 2027 decreased compared to FY 2026 by $2.490 million due to decreased emphasis on Aero-Structure Interactions and Control. This reduction reflects programmatic adjustments to the DAF Science and Technology portfolio for strategic realignment to optimize core research areas and improve resource efficiency. This will result in approximately 10 fewer grants awarded in Aero-Structure Interactions and Control.
FY2026: the year under way
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.

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.
| Fiscal Year | Estimate Type | Amount ($M) |
|---|---|---|
| FY2025 | Actual | 32.5 |
| FY2026 | Enacted | 30.8 |
| FY2027 | Request | 28.3 |
This activity is 34% of project 613002's FY2027 request and 9.5% of PE 0601102F'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.
