What the FY2027 request buys

Verbatim from the R-2A exhibit for project 675056 of PE 0101113F. 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 planned work

Will continue Agile and incremental software code development for version 1.0; continue development flight testing; create, test, and deploy software fix releases to integration labs and development flight test aircraft; prepare for Initial Operational Test and Evaluation (IOT&E).

FY2026 to FY2027 change

Funding levels decrease because test aircraft modification work will be complete; FY 2027 focus will be delivering software version 1.0 to flight test and fixing discrepancy reports found during development flight test.

Before the request year

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.

FY2026 plans — current year

Will continue Agile and incremental software code development for version 1.0; continue hardware/software integration Software Integration Lab tests; complete desktop training tool development; complete and deliver second test aircraft; complete ground test and flight testing on software version 0.5; start development flight test efforts on software version 1.0 (AFGSC-approved minimum viable product).

Money

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.

This activity is 100% of project 675056's FY2027 request and 7.2% of PE 0101113F'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.
