AF Satellite Comm System

The AFSCOM - AF Satellite Comm System program is a key line item in the Department of Defense (DoD) budget, managed by the United States Space Force under the Air Force. Its primary objective is to maintain, modernize, and sustain the Satellite Control Network (SCN), which is a globally distributed ground terminal network supporting command and control (C2) for over 170 satellites. The SCN provides critical support for DoD, Intelligence Community (IC), and NASA operations, including Positioning, Navigation and Timing (PNT), Intelligence, Surveillance and Reconnaissance (ISR), Missile Warning and Defense, Communications, Weather, Launch Vehicle Support, and Research and Development (R&D) satellites.

The SCN Commodity Procurements budget line focuses on the procurement, modification, refurbishment, installation, and testing of equipment necessary to maintain and optimize SCN operational capability. Funds are prioritized for addressing obsolescence and sustainment issues, with the potential for failed satellite contacts driving procurement priorities. Key objectives include replacing obsolete hardware with IP-based, software-defined modems, recorders, and control servers, transitioning software to a 64-bit architecture, and upgrading radome structures at Remote Tracking Stations (RTS) to protect against environmental damage.

Additionally, resources are allocated for upgrades to Range, Communications, and Network segments, as well as for studies on future planning and cybersecurity requirements. These efforts aim to ensure the SCN remains resilient and adaptable to evolving operational needs.

The SCN Knowledge-Based Services line item provides essential cybersecurity and test and evaluation (T&E) expertise to ensure system functionality and compliance. This includes submitting packages to Certifying Authorities for Authorizations to Operate (ATO) or Interim Authorizations to Test (IATT), streamlining the validation process, and supporting the Space Force Security Control Assessor (SCA). The program also delivers technical and acquisition support for integrating new systems and services into Space Systems Command (SSC) programs, standardizing systems engineering processes, and supporting all phases of the acquisition lifecycle.

The SCN Replenishment Spares budget line is dedicated to procuring spares for systems under sustainment contracts, ensuring that SCN users have the necessary parts to maintain and repair their equipment. This includes consumable and reparable spares, as well as capital equipment replacements for items such as processors, archival event recorders, timing systems, and components affected by Diminishing Manufacturing Sources and Material Shortages (DMSMS). These efforts are critical for minimizing downtime, maintaining operational readiness, and ensuring reliable satellite contacts.

Modernization and resiliency are central goals of the AFSCOM program. Funds support the upgrade of core SCN hardware and software, network automation, cyber defense work, and the replacement of obsolete components. The program aligns with Presidential Executive Order 14028 and National Security Memorandum 8, which emphasize the importance of cybersecurity and the adoption of zero trust principles across government systems. The Space Force also leverages commercial, government, and international partnerships to respond rapidly to emerging threats and operational needs in the contested space domain.

Another objective is to support launch and early orbit operations, providing worldwide telemetry during launch vehicle ascent, staging, and orbital insertion. The SCN ensures data transmission and reception for new satellites during early orbit checkout and conducts Factory Compatibility Testing (FCT) to verify satellite and launch vehicle communication capabilities prior to launch. These activities are vital for the successful deployment and operation of satellites each fiscal year.

The AFSCOM program includes funding reductions to promote efficiency and align with administration policies, such as Executive Order 14222, which seeks to advance government efficiency and cost savings. The program also supports requirements for financial audits as mandated by Title 10 U.S.C. Chapter 9A, Sec 240-D. The AF Satellite Comm System line item is designed to ensure the continued reliability, security, and modernization of the SCN, supporting a broad range of national security, intelligence, and civil space missions.
