Project 65A036 — RG-XX requests $355.9M in FY2027, 27% of the $1.32B requested for program element 1206425SF — a new start, with no prior-year and no current-year money. 1 R-2A activity decomposes the request, 1 new this cycle.

New start

This project requests $355.9M in FY2027 with no prior-year and no current-year funding. There is no incumbent line to compare it with — it did not exist before this President's Budget.

What project 65A036 buys

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 warning on adversary space operations; and conducting integrated command, control, communications, processing, analysis, dissemination, and archiving activities. This program element expands reconnaissance and surveillance SDA capabilities, deploying a constellation of new proliferated space vehicles (SVs), which will integrate with existing, but evolving Space Control operations. 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, risk mitigation, and test & evaluation, and may include prototyping and technology demonstration. RG-XX will increase SDA capabilities and capacity to detect, track, and characterize threats to high value U.S. and allied satellites. SVs will use dynamic Rendezvous and Proximity Operations (RPO) capabilities and may include refueling capability. RG-XX will use a flexible acquisition construct enabling concurrent and rapid onboarding of multiple new SV vendors, incorporate allied nation partnerships, and leverage commercial capabilities and services. RG-XX requirements are based on a Rapid Prototyping Requirements Document (RPRD) and a classified Capability Description Document (CDD). RG-XX will provide critical Fire Control capability such as search, detect, and track objects from space-based sensors for timely custody and event detection. Reconnaissance and Surveillance from space augments and overcomes existing ground sensor limitations with timely 24-hour above-the-weather collection of satellite metric data only possible with space-based sensors.

Project 65A036 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.

1 accomplishment / planned program

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.

FY 2027 will continue activities for implementation of system resiliency and situational awareness necessary to operate in the contested space domain environment. Activities may include, but are not limited to: program office support, studies, technical analysis, experimentation integration and test of command and control (C2)…
