This activity requests $45.3M in FY2027, 100% of project 2063, down 46% 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 2063 of PE 0604366N. 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

Complete Developmental Test and Verification static fire testing, conduct an In Process Review (IPR) to establish the initial product design and begin qualification and insensitive munitions testing at the rocket motor level. Complete the Ballistic Test Vehicle -2 design and execute live fire to demonstrate the qualified rocket motor design in a flight test environment.

FY2026 to FY2027 change

The decrease results in reduced rocket motor qualification requirements and a de-scoping of the Ballistic Test Vehicle 2 (BTV-2) 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

Start the Developmental Test and Verification static fire testing series for the new rocket motor, conduct an In Process Review (IPR) to establish the Functional and allocated baseline design. Complete Ballistic Test Vehicle build and execute live fire event to demonstrate new rocket motor. Complete qualification of 21" Steering Control Section.

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 2063's FY2027 request and 8.4% of PE 0604366N'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.
