What the FY2027 request buys
Verbatim from the R-2A exhibit for project MSL-01 of PE 0602025E. 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.
- Conduct assessment of designs to understand ability to meet mass production requirements. - Develop preliminary design of integrated system. - Test sub-scale solid rocket motor assembly. - Compare preliminary designs to potential transition partner requirements.
The FY 2027 decrease reflects the shift from feasibility testing to sub-scale motor assembly testing.
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.
- Develop physics models to validate component-level feasibility analysis. - Resolve trade studies for conceptual design. - Validate concept viability for testing and integration phase. - Perform feasibility tests of components for proof-of-concept validation. - Understand system requirements of conceptual design.
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 | 28.8 |
| FY2027 | Request | 18.7 |
This activity is 14% of project MSL-01's FY2027 request and 1.1% of PE 0602025E'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.
