What the FY2027 request buys
Verbatim from the R-2A exhibit for project 675046 of PE 0303133F. 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.
-Will begin requirements refinement -Will begin Increment 1 Development -Will begin Increment 1 Test and Evaluation -Will complete Increment 2 antenna coupler prototyping -Will begin Increment 2 antenna coupler test and evaluation -Will complete Increment 2 critical design review of antenna coupler -Will begin software integration of with ARC-260 with antenna coupler
The $13.506 million increase from FY 2026 to FY 2027 is due to the development of Increment 1, a comprehensive software and firmware effort projected to last a year and a half, which is required for the successful integration of the new digital coupler in Increment 2.
FY2026: the year under way
Prior-year accomplishments and current-year plans from the same exhibit. Context for the FY2027 plan, not a series — an activity partitions its project exactly in the request year, but can under-cover it in earlier years.
-Will perform Vendor site visits to determine Vendor eligibility -Will select Vendor for digital coupler development -Will begin risk assessment and cost analysis activities -Will perform system engineering trade studies -Will begin requirements refinement and validation activities -Will begin AN/ARC-260 digital coupler prototyping
Three years, and no five-year plan
An R-2A activity publishes the prior year, the current year and the budget year. The FYDP outyears exist at project and program-element level and are deliberately absent here rather than inferred. Estimate types are colored and never summed into one figure.
| Fiscal Year | Estimate Type | Amount ($M) |
|---|---|---|
| FY2025 | Actual | 8.4 |
| FY2026 | Enacted | 19.7 |
| FY2027 | Request | 33.2 |
This activity is 100% of project 675046's FY2027 request and 100% of PE 0303133F'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.
