What the FY2027 request buys
Verbatim from the R-2A exhibit for project 622502 of PE 0602602F. 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 developing validated mesoscale modeling and simulation tools for computational physics sciences application of ordnance performance and aging, enabling evolving ordnance concepts development necessary to build a more lethal force. - Continue to develop ordnance engineering-level simulation architecture capabilities, enabling weapon sub-system and system-level technology assessments. - Continue implementing cost-effective and rapid-transition warhead technologies for inventory weapons, supporting weapons affordable mass. - Continue modeling and simulation efforts exploring the ordnance technology trade-space for low-cost, long-range munition concepts, enabling evolving ordnance concepts development necessary to build a more lethal force. - Continue developing predictive techniques for munition effectiveness tools used in concept development and assessment as well as studies involving analysis of alternatives, focusing on investigation and development of ordnance sub-systems (energetics, fuzes, and warheads) and integrated system concepts using modeling and simulation tools. - Continue developing test capability and data collection for modeling and simulation tools to characterize lethality, survivability, and performance of sub-systems and integrated ordnance systems, focusing on investigating and development of ordnance sub-systems (energetics, fuzes, and warheads) and integrated system concepts using modeling and simulation tools. Investigate using embedded lethality tools in weapons for higher lethality and to reduce salvo sizes. - Continue investigation of computational intelligence technologies for shorten design cycles and predictive lethal effects applications, supporting deep learning methodology development to develop whole target lethality models that run fast for weaponeer and designer use. - Continue exploring the connection of ordnance modeling and simulation and lethality tools to the broader digital engineering ecosystem, focusing investigation and development of ordnance sub-systems (energetics, fuzes, and warheads) and integrated system concepts using modeling and simulation tools. - Continue development and maturation of a mini-JSE node to conduct analysis at mission and campaign level for evaluation of munition research, optimizing science and technology (S&T) investments to meet warfighter needs. - Continue development and integration of maritime lethality analysis and assessment tools for air-delivered weapons delivered by the warfighter in three counter maritime scenarios, optimizing S&T investments to meet warfighter needs.
FY 2027 decreased compared to FY 2026 by $3.240 million decreasing emphasis on modeling, simulation, and analysis and lethality/weaponeering software tool development that supports operation plan weapon-target pairing and operational magazine depth estimates.
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 | 34.6 |
| FY2026 | Enacted | 33.9 |
| FY2027 | Request | 30.7 |
This activity is 55% of project 622502's FY2027 request and 24% of PE 0602602F'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.
