What the FY2027 request buys
Verbatim from the R-2A exhibit for project 672671 of PE 0207133F. 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.
Continued development and testing of AESA Phase 3.4 radar software capabilities which include completing integration of Enhanced Data Link, Improvements and Enhancements to A-A and A-G Combat Identification and Maritime Detection; Electronic protection improvements and engineering support to complete F-16 post block implementation of Ethernet messaging. Additional engineering support to improve RF compatibility with SIU to complete RFC CDD. Additional engineering and software support to improve radar integration with derived requirement RIP+.
Increase of $0.564M from FY26 to FY27 is minimal, FY27 burn rate expected to be very similar to FY26.
FY2026: the year under way
Prior-year accomplishments and current-year plans from the same exhibit. Context for the FY2027 plan, not a series — an activity partitions its project exactly in the request year, but can under-cover it in earlier years.
Complete and field AESA Phase 3.3 software capabilities. Begin development of AESA Phase 3.4 radar software capabilities which include completing integration of Enhanced Data Link, Improvements and Enhancements to A-A and A-G Combat Identification and Maritime Detection; Electronic protection improvements and engineering support to complete F-16 post block implementation of Ethernet messaging. Additional engineering support to improve RF compatibility with SIU to complete RFC CDD. Additional engineering and software support to improve radar integration with derived requirement RIP+.
Three years, and no five-year plan
An R-2A activity publishes the prior year, the current year and the budget year. The FYDP outyears exist at project and program-element level and are deliberately absent here rather than inferred. Estimate types are colored and never summed into one figure.
| Fiscal Year | Estimate Type | Amount ($M) |
|---|---|---|
| FY2025 | Actual | 4.3 |
| FY2026 | Enacted | 21.4 |
| FY2027 | Request | 21.9 |
This activity is 4.2% of project 672671's FY2027 request and 4.2% of PE 0207133F'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.

Every R-2A line of this project, largest FY2027 request first. Linked where the activity has enough of its own narrative to carry a page; the rest are shown in full on the program-element page.
