What the FY2027 request buys
Verbatim from the R-2A exhibit for project 1662 of PE 0204136N. 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.
Continue the development and hardware integration of GL on the F/A-18E/F and software integration on the F/A-18E/F and EA-18G. Provide aircraft integration to support two-way data and voice BLOS capability. Continue integration of two-way data and voice communication and an aperture for use over satellite constellations. Development of a ground test infrastructure to enable complete end-to-end test. This will include system development and on aircraft integration to support testing. Continue Depot Level stand up of the F/A-18 E/F GL capability.
FY2026 to FY2027 decrease of $33.386M for Global Lightning (GL) is due to JTT-X development and testing ramping down.
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.

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 | 68.6 |
| FY2026 | Enacted | 66.8 |
| FY2027 | Request | 33.4 |
This activity is 13% of project 1662's FY2027 request and 12% of PE 0204136N'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.
