What the FY2027 request buys
Verbatim from the R-2A exhibit for project 730 of PE 0603838D8Z. 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.
T-REX will expand cross domain integration, incorporate additional technologies and refine techniques, data collection, data and knowledge management.
The increase from FY 2026 to FY 2027 provides more continuous experimentation opportunities and industry engagement while bolstering Body of Evidence collection for advancing prototypes.
FY2025–FY2026: what came before
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.
In FY 2026, T-REX will support two T-REX events in Indiana to assess ~120 projects from Industry, the Services, the CCMDs, and Coalition Partners focusing on multi-domain uncrewed experimentation, low-cost short range air defense, Integrated Base Defense, and CCMD Priorities. Additionally, support is provided to various OCONUS joint experimentation venues based on operational need and utility.
In FY 2025, T-REX will support one Limited Objective Experimentation and one T-REX event in Indiana to assess ~100 projects from Industry, the Services, the CCMDs, and Coalition Partners focusing on counter-Unmanned Aerial Systems (c-UAS) and Integrated Base Defense. Additionally, support is provided to various OCONUS joint experimentation venues based on operational need and utility.
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 | 24.9 |
| FY2026 | Enacted | 24.7 |
| FY2027 | Request | 25.5 |
This activity is 12% of project 730's FY2027 request and 8.2% of PE 0603838D8Z'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.
