What the FY2027 request buys
Verbatim from the R-2A exhibit for project PS1 of PE 0604820A. 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.
FY 2027 funds will support: - Continue building of prototype assets to be used for qualification and developmental testing - Validate Safety and Human System Integration designs - Begin Developmental testing - Participate in Transformation in Contact (TIC) activities
Decrease in FY 2027 funds are due to initial transition from development to production.
FY2025–FY2026: what came before
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.
FY26 funds will support: - Continued development of system design - Create interface specifications and drawings - Building of prototype assets to be used for qualification, and developmental and operational testing - Safety and Human System Integration designs
FY25 plans will support: - Continue development and trade studies - Develop statutory/regulatory documentation
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) |
|---|---|---|
| FY2025 | Actual | 13.8 |
| FY2026 | Enacted | 34.4 |
| FY2027 | Request | 25.0 |
This activity is 100% of project PS1's FY2027 request and 43% of PE 0604820A'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.
