What the FY2027 request buys
Verbatim from the R-2A exhibit for project DAT-01 of PE 0603467E. 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.
- Execute Critical Design Review (CDR) for larger scale demonstrator vehicle. - Purchase materials for manufacturing of the larger scale demonstrator vehicle. - Continue to test software control system for demonstrator. - Continue to update the software control system for demonstrator. - Continue manufacture of the demonstrator vehicle. - Continue to build the larger scale demonstrator article subsystems. - Continue to test the larger scale demonstrator article subsystems.
The FY 2027 increase reflects increase in manufacturing larger subsystems for the larger scale demonstrator.
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.
- Complete motor risk reduction assembly testing and incorporate lessons learned. - Complete testing for the smaller scale demonstrator article and incorporate lessons learned. - Execute Preliminary Design Review (PDR) for larger scale demonstrator vehicle. - Complete detailed design of the demonstrator vehicle. - Purchase long-lead items for demonstrator vehicle. - Initiate manufacture of the demonstrator vehicle. - Conduct subsystem modeling, simulation, and analysis activities. - Conduct High Performance Computing (HPC) performance modeling to validate performance. - Complete the development, building, and testing of the quarter scale demonstrator article subsystems.
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.
| Fiscal Year | Estimate Type | Amount ($M) |
|---|---|---|
| FY2026 | Enacted | 61.8 |
| FY2027 | Request | 73.4 |
This activity is 18% of project DAT-01's FY2027 request and 4.7% of PE 0603467E'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.

Every R-2A line of this project, largest FY2027 request first. Linked where the activity has enough of its own narrative to carry a page; the rest are shown in full on the project page.
