What the FY2027 request buys
Verbatim from the R-2A exhibit for project ACX-01 of PE 0603468E. 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.
- Continue to conduct flight hardware acceptance testing for the propulsion system. - Continue to integrate the developed propulsion systems with the air harvesting inlets. - Continue conducting environmental qualification tests for the air harvesting inlets. - Finalizing ground software build and testing. - Finalizing flight software build and testing. - Integrate the satellite onto the launch provider. - Launch of the satellite.
The FY 2027 increase reflects the shift from design and build activities to final satellite integration, launch and on orbit demonstration.
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.
- Conduct flight hardware acceptance testing for the propulsion system. - Integrate the developed propulsion systems with the air harvesting inlets. - Conduct environmental qualification tests for the air harvesting inlets. - Continue ground software build and testing. - Continue flight software build and testing. - Kick-off the launch services partner process.
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 | 35.8 |
| FY2027 | Request | 47.7 |
This activity is 9.5% of project ACX-01's FY2027 request and 8.8% of PE 0603468E'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.
