This activity requests $37.3M in FY2027, 12% of project 676020, up 57% on FY2026. The R-2A exhibit describes it across FY2026–FY2027, including what the FY2027 money is planned to buy.

What the FY2027 request buys

Verbatim from the R-2A exhibit for project 676020 of PE 0207134F. 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

Continue and expand software integration efforts with R-EGI prototypes in the system integration lab; maintain F-15 development baseline with R-EGI updates; expand testing and F-15-specific non-recurring engineering activities.

FY2026 to FY2027 change

Increase in funds for continuation of non-recurring engineering and software integration efforts.

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

Continue and expand software integration efforts with R-EGI prototypes in the system integration lab; maintain F-15 development baseline with R-EGI updates; expand testing and F-15-specific non-recurring engineering activities.

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 12% of project 676020's FY2027 request and 12% of PE 0207134F'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.
