What the FY2027 request buys
Verbatim from the R-2A exhibit for project L39 of PE 0604804A. 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.
Finish development phase and conduct validation testing of JPADS V4 and Long Range JPADS 2K.
Configuration will be frozen mid-FY, at which point development will be complete, resulting in less required funding for JPADS in FY27.
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.
Continue EMD phase of JPADS V4 development. Conduct testing to support preliminary design review, locking in functional baseline of GPS-denied kit. Additionally, begin EMD phase of Long-Range JPADS 2K, which includes a significant amount of prototyping and flight testing .
Begin EMD phase of JPADS V4 development. Down-select GPS-denied sensors, mature software architecture and finalize hardware interface design. Test early prototype at Position, Navigation, and Timing Assessment Exercise 2025 (PNTAX 25).
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 | 3.9 |
| FY2026 | Enacted | 12.0 |
| FY2027 | Request | 11.1 |
This activity is 72% of project L39's FY2027 request and 17% of PE 0604804A'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 project page.
