This activity requests $1.37B in FY2027, 100% of project 640017, up 1142% 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 640017 of PE 0207147F. 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

Collaborative Combat Aircraft will continue to conduct studies and analyses, identify technology candidates, execute concept refinement activities, execute technology maturation and risk reduction activities, execute engineering and manufacturing development activities, as well as weapon systems development, integration, test, prototyping, demonstrations, and crewed systems integration to reduce risk and mature CCA concepts and air superiority related technologies.

FY2026 to FY2027 change

Funding increased for acceleration of additional capability development.

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

Collaborative Combat Aircraft will continue to conduct studies and analyses, identify technology candidates, execute concept refinement activities, execute technology maturation and risk reduction activities as well as weapon systems development, integration, test, prototyping, demonstrations, and crewed systems integration to reduce risk and mature CCA concepts and air superiority related technologies.

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 640017's FY2027 request and 100% of PE 0207147F'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.
