What the FY2027 request buys
Verbatim from the R-2A exhibit for project E10 of PE 0604820A. 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.
Sentinel A4: Funding will support further developmental and operational testing of the Sentinel A4 program against evolving theater specific threats. Will allow for continued software qualification and hardware testing, as well as field testing against representative targets. Sentinel A3: Funding supports required documentation for materiel release of software upgrades for Sentinel A3.
Increase in FY 2027 supports additional testing of the A4 radar against evolving threat representative targets.
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.
FY 2026 funds supports but is not limited to: Sentinel A4: Will execute phase two of Initial Operational Test and Evaluation (IOT&E) for Sentinel A4 and the Operational Assessment required for a Full Rate Production (FRP) decision in FY26. Funding will support further developmental and operational testing of the Sentinel A4 program against evolving theater specific threats. Will allow for continued software qualification and hardware testing, as well as field testing against representative targets. Funding will support required documentation for materiel release of software upgrades for Sentinel A4. Sentinel A3: Funding supports required documentation for materiel release of software upgrades for Sentinel A3.
Will execute phase one of Initial Operational Test and Evaluation (IOT&E) for Sentinel A4. Will conduct software qualification test and hardware verification testing, field testing against representative targets. Prepares required documentation for materiel release of software and hardware upgrades for Sentinel A3 and Sentinel A4.
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 | 13.1 |
| FY2026 | Enacted | 9.8 |
| FY2027 | Request | 11.1 |
This activity is 34% of project E10's FY2027 request and 19% of PE 0604820A'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.
