What the FY2027 request buys
Verbatim from the R-2A exhibit for project 652286 of PE 0604735F. 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.
FY2027 focuses on completing manufacture, integration, test, and delivery of the ARTS-V3 X-band in FY2027 and C-band in FY2028 in order to enable production start in FY2028. Integration efforts will focus on open air testing and achieving IOC at the Nevada Test and Training Range.
Nominal funding increase to support program office estimate.
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.
The focus of FY2026 is building the Production Representative Article (PRA) and conducting combined developmental/operation test activities. Activities will include but are not limited to remaining hardware purchases, fabrication of radar sub-assemblies and higher level assemblies, component-level and sub-system level testing, continued development of the command & control software, integration activities with the command & control software, software-defined threat profile development/integration, and engineering activities to reduce integration risk during open-air full system testing in FY2027.
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 | 117.8 |
| FY2026 | Enacted | 111.1 |
| FY2027 | Request | 112.2 |
This activity is 85% of project 652286's FY2027 request and 85% of PE 0604735F'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.
