What the FY2027 request buys

Verbatim from the R-2A exhibit for project 670131 of PE 0207146F. 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 non-recurring engineering (NRE) and integration development efforts on multiple contracts to develop and integrate multi-band apertures and terminals with aircraft systems. Modify aircraft software (Operational Flight Program) to enable integration and data sharing in accordance with DAF Battle Network architecture leveraging other Long Range Kill Chain (LRKC) demos. Continue software integration allowing for adjunct processor capability while beginning install for test jets.

Additional funding for continued non-recurring engineering and beginning of test jet installs

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

Begin non-recurring engineering (NRE) and integration development efforts on multiple contracts to develop and integrate multi-band apertures and terminals with aircraft systems. Modify aircraft software (Operational Flight Program) to enable integration and data sharing in accordance with DAF Battle Network architecture leveraging other Long Range Kill Chain (LRKC) demos.

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 34% of project 670131's FY2027 request and 34% of PE 0207146F'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.
