This activity requests $46.1M in FY2027, 53% of project 645601, up 27% on FY2026. The R-2A exhibit describes it across FY2026–FY2027, including what the FY2027 money is planned to buy.

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.

FY2027 planned work

- ROOSTER: Support shipment and launch integration efforts for the ROOSTER-4 space vehicle, pending updated launch plans. For ROOSTER-5, complete platform development and factory testing of the ROOSTER-5 space vehicle and begin integrated test campaign. Prepare for shipment and launch integration efforts. Obtain security and policy approval for the test campaigns of both integrated space vehicles and launch stacks, USSF-43 and USSF-70, respectively. For ROOSTER-6, award integration contract to begin initial integration and development of the space vehicle platform. Rapidly respond to implement system resiliency and situational awareness necessary to operate in the contested space domain. Activities may include, but are not limited to program office support, studies, technical analysis, experimentation, risk reduction, prototyping, and activities that may leverage commercial, U.S. Government partnership, and international opportunities to respond to existing and emerging adversarial threats with speed and agility. - Tetra: Finish Tetra 5 and continue storage pending updated launch plans (USSF-43). Continue development of Tetra 6 and continue storage pending updated launch plans (USSF-155). Continue storage of Tetra 3 and 4. Initiate follow-on space vehicle bus development and payload integration. Award future Tetra contract(s). - Quasi-Zenith Satellite System-Hosted Payload (QZSS-HP): Continue international cooperation with Japan by maturing system components and connectivity with internal and external systems. Continue maturation of the ground system data dissemination in support of HP-1 and HP-2 in preparation for acceptance as dedicated sensors to the Space Surveillance Network.

FY2026 to FY2027 change

FY 2027 increased by $9.916 million due to continued development of the Rapid On-Orbit Space Technology Evaluation Ring (ROOSTER)-6 bus.

Before the request year

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.

FY2026 plans — current year

- Rapid On-Orbit Space Technology Evaluation Ring (ROOSTER): Support shipment and launch integration efforts for the ROOSTER-4 Space Vehicle. Continue development and integration of the ROOSTER-5 space vehicle and begin the factory test campaign. Obtain security and policy approval for the test campaigns of both integrated space vehicles and launch stacks USSF-43 and USSF-70, respectively. Initiate follow-on space vehicle bus and payload development. Award ROOSTER-6 contract. - Tetra: Continue development of Tetra 5 & Tetra 6, in addition to pending launch plans. Continue storage of Tetra 3 and 4 pending updated launch plans. - Quasi-Zenith Satellite System—Hosted Payload: Continue international cooperation with Japan by maturing system components and connectivity with internal and external systems. Continue ground system and data communication development.

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.

This activity is 53% of project 645601's FY2027 request and 53% 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.
