What the FY2027 request buys
Verbatim from the R-2A exhibit for project 645601 of PE 1206427SF. 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.
- ROOSTER: For ROOSTER-4, finish payload integration; support launch integration and launch, pending updated launch plans. Begin the execution of the 12-month on-orbit prototype testing and demonstration phase. Conduct on-orbit tests and demonstrations to enable technology maturation. For ROOSTER-5, continue integrating manifested payloads, begin launch integration campaign, continue ground system development and testing. Begin mission CONOP development. For ROOSTER-6, develop tunable payload dispensers with standardized interfaces to reduce payload integration costs and increase rideshare hosting opportunities for rapid needs. - Tetra: Finish integration, storage and operations to support future launch of Tetra 5 and 6 space vehicles, pending updated launch plans. - Quasi-Zenith Satellite System-Hosted Payload (QZSS-HP): Continue international cooperation with Japan via ongoing on-orbit testing and experimentation of HP-1 as well as final integration, launch, initial on-orbit testing, and experimentation of HP-2. Support sensor calibration, on-orbit experimentation, data validation/dissemination, and preparations for on-orbit operational leave-behind of both HPs.
FY 2027 decreased by $6.450 million due to completion of the integration activities of Rapid On-Orbit Space Technology Evaluation Ring (ROOSTER)-4, Tetra-5a, and QZSS-HP QZS 7-HP.
FY2026: the year under way
Prior-year accomplishments and current-year plans from the same exhibit. Context for the FY2027 plan, not a series — an activity partitions its project exactly in the request year, but can under-cover it in earlier years.
- ROOSTER: For ROOSTER-4, complete payload integration; support launch integration and launch; and begin the execution of the 12-month on-orbit prototype testing and demonstration phase. Conduct on-orbit tests and demonstrations to enable technology maturation. For ROOSTER-5, continue payload integration for manifested payloads; begin ground system development, integration, and testing. - Tetra: Continue integration, storage and operations to support future launch of Tetra 3, 4 & 5 space vehicles in FY 2026, pending updated launch plans. - QZSS-HP: Continue international cooperation with Japan via on-orbit testing and experimentation of HP-1 as well as final integration, launch and initial testing of HP-2. Support sensor calibration, on-orbit experimentation, and data validation/dissemination.
Three years, and no five-year plan
An R-2A activity publishes the prior year, the current year and the budget year. The FYDP outyears exist at project and program-element level and are deliberately absent here rather than inferred. Estimate types are colored and never summed into one figure.
| Fiscal Year | Estimate Type | Amount ($M) |
|---|---|---|
| FY2025 | Actual | 22.6 |
| FY2026 | Enacted | 28.0 |
| FY2027 | Request | 21.6 |
This activity is 25% of project 645601's FY2027 request and 25% of PE 1206427SF'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.
