What the FY2027 request buys
Verbatim from the R-2A exhibit for project 627757 of PE 0602202F. 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 advancing dose-response models by incorporating experimental findings on high-pulse-energy injury and investigating machine learning techniques to expand applicability across parameter spaces. -Continue advancing 3-dimensional digital anatomical models by validating adaptive meshing techniques, which optimize computational speed while retaining the ability to evaluate damage in anatomical regions of interest. -Continue maturing HPC approaches by conducting pilot efforts to integrate prior-year modeling outcomes into broader Department of War end-to-end modeling environments. -Continue updating the dose-response library by transitioning data on high-energy laser skin injury severity and incorporating new endpoints for eye damage from experimental data. -Complete a study on extending modeling approaches by maturing machine learning surrogates and incorporating them into components for predicting biological outcomes in engagement-level simulations. -Complete the development of virtual reality models by incorporating experimental findings on color shifts from protective devices and developing features to portray visual obscurations realistically for wargaming.
FY 2027 increased compared to FY 2026 by $1.086 million due to minor programmatic adjustments to the DAF Science and Technology portfolio.
FY2026: the year under way
Prior-year accomplishments and current-year plans from the same exhibit. Context for the FY2027 plan, not a series — an activity partitions its project exactly in the request year, but can under-cover it in earlier years.
-Continue advancing dose-response models to incorporate injury severity as a function of directed energy weapon parameters and deliver validated software components for integration into analysis and weaponeering products. -Continue advancing 3-dimensional digital anatomical models by increasing resolution and incorporating adaptive meshing to efficiently evaluate damage from both heat and stress wave mechanisms. -Continue maturing high-performance computing (HPC) approaches to quantify uncertainty in multi-physics bioeffect simulations and integrate directed energy injury endpoints into Department of War HPC tool suites. -Continue extending modeling approaches by using physics-informed machine learning to surrogate complex physics-level simulations for digital human representation throughout analyses. -Complete the Virtual Reality component for vision effects (glare/dazzle) by transitioning laser dazzle simulations for integration into experimental wargames and training products. -Commence updates to the dose-response library based on new scientific data that parameterizes skin injury severity from emerging directed energy systems.
Three years, and no five-year plan
An R-2A activity publishes the prior year, the current year and the budget year. The FYDP outyears exist at project and program-element level and are deliberately absent here rather than inferred. Estimate types are colored and never summed into one figure.
| Fiscal Year | Estimate Type | Amount ($M) |
|---|---|---|
| FY2025 | Actual | 27.0 |
| FY2026 | Enacted | 24.1 |
| FY2027 | Request | 25.2 |
This activity is 61% of project 627757's FY2027 request and 24% of PE 0602202F'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.
