This activity requests $34.0M in FY2027, 3.6% of project 674785, down 38% 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 674785 of PE 0207138F. 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

Continued deliveries of Tanks and Pylons test assets. Continue Weapon Separation and Jettison testing to support Developmental Test (DT) / Occupational Test (OT) efforts. Begin final certification efforts for flight testing. Continue full Pylon qualification efforts.

FY2026 to FY2027 change

Decrease of $20.996 million from FY2026 to FY2027 is attributable to the program's completion of testing and certification efforts, as well as ramping down Engineering and Manufacturing Development (EMD) activity as the program moves further into the production phase.

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

Continued Flight Test for LDTP to Threshold envelope. Verification and Validation of Weapon Separation and Jettison, and lightning testing. Stress analysis testing completion and documentation. Support of software Release Testing. Developmental Test (DT) / Occupational Test (OT) efforts to continue to support certification of ground and flight test to gain air worthiness approval.

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 3.6% of project 674785's FY2027 request and 3.6% of PE 0207138F'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.
