What the FY2027 request buys
Verbatim from the R-2A exhibit for project 65A041 of PE 1206425SF. 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 continues the development and build of the first SG-XX constellation increment. Space Vehicle (SV) providers will support design reviews and initiate efforts critical to timely and cost-effective SV production. SV providers will collaborate and coordinate with the ground-based systems provider and other SV providers to establish common standards and protocols, improving mission effectiveness. Ground development and integration efforts will begin, and efforts will include mission unique software development and integration into an enterprise ground network construct. Additionally, the development of training curriculum and preparations for operator training will commence. Technology enhancements and prototyping efforts for space-based space domain surveillance against evolving threats, may include, but are not limited to: future upgrades, extension and augmentations through analysis, studies, demonstrations, and experimentation. FY 2027 will seek opportunities for commercial, international, academic, and Federally Funded Research and Development Center (FFRDC) partnerships. Efforts will include implementation of mission data processing and data dissemination efforts. Efforts will include the integration of YSG-XX prototyping efforts into the SG-XX technical baseline, which will inform future SG-XX spacecraft and sensor development. YSG-XX prototype activities will focus on completing host development, integration, and preparations for the launch and on-orbit demonstration of two commercial spacecraft. This demonstration will enhance system resiliency and situational awareness for operations in the contested space domain. System Engineering, Integration and Test (SEIT) efforts may include, but are not limited to: technology road mapping and improving coordination and collaboration across SG-XX Ground and SV segments, collaboration with other SDA programs (e.g. RG-XX), and down-stream programs anticipated to leverage SG-XX mission capabilities. Working groups will be coordinated and established, facilitating risk mitigation and cross-program collaboration, facilitating system-of-system integration and effectiveness. Activities may include, but are not limited to: program office support, studies, technical analysis, experimentation integration and test of command and control (C2), resiliency measures, risk mitigation, mission partner interfaces, commercial and international partner engagement, space test/combat range events and office support, etc.
FY 2027 funding increase reflects the initial request of discretionary funds for the SG-XX program for continued development of the first SG-XX constellation increment. FY 2026 mandatory funds initiated this effort.
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.
The efforts described in the description are resourced with mandatory funds within this program element in FY 2026.
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 | 0.0 |
| FY2027 | Request | 370.9 |
This activity is 100% of project 65A041's FY2027 request and 28% of PE 1206425SF'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.
