What the FY2027 request buys
Verbatim from the R-2A exhibit for project MX46 of PE 0603907C. 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.
- Complete initial hardware design of the next generation server architecture required to counter the increased threat vector. - Deliver XBR software build 4.4 formal release. - Initiate MBSE by creating initial models for SBX radar behavior, antenna mount, and functional representation validation. - Initiate SBX GaN TRIMM upgrades to mitigate obsolescence and improve radar performance.
Increase from fiscal year (FY) 2026 to FY 2027 provides for: - Initiation of MBSE by creating initial models for SBX radar behavior, antenna mount, and functional representation validation. - Initiation of SBX GaN TRIMM upgrades to mitigate obsolescence and improve radar performance.
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.
- Initiate technology refresh development and prototype for the next generation server architecture.
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 | 80.7 |
| FY2026 | Enacted | 80.5 |
| FY2027 | Request | 140.1 |
This activity is 53% of project MX46's FY2027 request and 51% of PE 0603907C'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.
