This activity requests $24.4M in FY2027, 29% of project 613002, down 8.1% on FY2026. The R-2A exhibit describes it across FY2026–FY2027, including what the FY2027 money is planned to buy.

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.

FY2027 planned work

- Continue exploring scientific advances by integrating core disciplines of combustion, plasma dynamics, chemistry, hydrodynamics, structural dynamics, and multi-fidelity simulations. - Continue to investigate processes associated with the generation, storage, and utilization of energy, specifically for Department of the Air Force systems, including developing novel energetic materials as well as understanding, optimizing, and controlling combustion processes.

FY2026 to FY2027 change

FY 2027 decreased compared to FY 2026 by $2.149 million due to decreased emphasis on Energy, Power, and Propulsion. 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 9 fewer grants awarded in Energy, Power, and Propulsion.

Before the request year

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.

FY2026 plans — current year

- Explore scientific advances by integrating core disciplines of combustion, plasma dynamics, chemistry, hydrodynamics, structural dynamics, and multi-fidelity simulations. - Investigate processes associated with the generation, storage, and utilization of energy, specifically for Department of the Air Force systems, including developing novel energetic materials as well as understanding, optimizing, and controlling combustion processes.

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 29% of project 613002's FY2027 request and 8.2% 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.
