What project 656565 buys
SSC/SYD 85/BAS is developing the Deep Space Advanced Radar Capability (DARC) (Project 656565) for Guardians across the USSF Space Domain Awareness (SDA) mission, Combined Forces Command, Mission Delta 2, and 20th Space Surveillance Squadron. As a result, the Service will (Pick at least one FY27 Effects, one enduring effect and add optional as needed). Space Domain Awareness (SDA) is one of five core competencies of the Space Force and is the effective identification, characterization, and understanding of any factor, passive or active, associated with the space domain that could affect space operations and thereby impact the security, safety, economy, or environment of our nation. As the foundation for space control, SDA encompasses surveillance of all space objects and activities; detailed surveillance of specific space assets; monitoring space environmental conditions; monitoring cooperative space assets; gathering indications and warnings on adversary space operations; and conducting integrated command, control, communications, processing, analysis, dissemination, and archiving activities. This program element develops, tests, upgrades and fields new SDA capabilities across the space surveillance network (SSN) while companion program element 1203940SF develops, fields, and operationalizes sensor networks and information integration capabilities. Activities funded in this program element (1206425SF) also support efforts such as engineering studies and analyses, architectural engineering studies, trade studies, technology needs forecasting, modernization initiatives, systems engineering, system development, and test & evaluation. Activities may include prototyping and technology demonstration(s). This program falls within the SDA mission area which provides a ground-based radar system that detects, tracks, and maintains custody of deep space objects 24/7 in all weather and through the solar exclusion gap. DARC will augment the Space Surveillance Network as an additional sensor with increased capacity and capability for deep space object custody, providing full global coverage. The FY 2026 spend plan amount includes $0 thousand of discretionary and $281,861 thousands of mandatory (reconciliation) for a total of $281,861 thousands. The mandatory funds continue construction and integration of Site 1, and development of Sites 2 & 3.

Project 656565 funding, FY2025–FY2031
Prior years are actuals, the budget year is the request, and the outyears are the FYDP plan. Estimate types are colored and never summed into one figure. Projects carry the full five-year plan; the activities inside them stop at the budget year.

The R-2A exhibit — the only level of the budget that describes work that has not happened yet. Activities carry the prior, current and budget year only, no five-year plan. Each describes FY2027 work in enough detail to have its own page; the rest are shown here in full. Coverage is partial across the corpus, so count activities, never total them.
Complete Site 1 Operational Testing, deliver the Operational Leave-Behind Capability, and begin Interim Contract Support. Continue Site 2 pre-construction activities and begin site construction. For Site 3, the Program Office will initiate engineering and design work. These efforts include execution of critical activities such as…

Performers named in the R-3 exhibit under this project. Share is of the project's whole FY2027 R-3 total — the same denominator the program-element split uses, so the two read on one scale and will not sum to 100% when unnamed or government work is in the mix. Budget-justification contract funding, not obligations.
