Spaceborne Equip (Comsec)

The Spaceborne Equip (Comsec) program, as outlined in the Department of the Air Force's FY 2026 budget request, is a critical procurement line under the Space Force's Space Programs portfolio. The primary goal of this program is to acquire and sustain cryptographic products and communications security (COMSEC) equipment essential for safeguarding Department of Defense (DoD) satellite platforms and the associated ground nodes that link to space assets. This equipment is foundational for achieving space information superiority and ensuring the confidentiality, integrity, and availability of mission-critical data in support of national security objectives.

Space Communications Security (COMSEC) is the central focus of this line item, with objectives centered on procuring centrally-funded cryptographic products such as End Crypto Units (ECUs), Embedded Solutions (ES), Transmission Security (TRANSEC) devices, and related ancillaries. These products are designed to operate in the challenging space environment and provide secure communications for both spaceborne and terrestrial nodes. The program supports compliance with CNSSP No. 12, which governs cybersecurity for space systems supporting national security missions.

By enabling secure command and control (C2) of satellites and protecting telemetry, tracking, and command (TT&C) data, Space COMSEC mitigates the risk of adversarial interception, manipulation, or destruction of sensitive information.

Logistics is a significant component of the Spaceborne Equip (Comsec) program, ensuring the long-term sustainment of COMSEC products throughout their 20-to-40-year lifecycle. The logistics objective includes procuring specialized test sets, certified training materials, maintenance manuals, spare components, and modifications necessary to maintain operational readiness. These products are provided as Government Furnished Equipment (GFE) to contractors and ground stations, with the Air Force responsible for organic sustainment and component-level maintenance.

Funding supports ongoing lifecycle sustainment and ensures that mission requirements for the Department of the Air Force (DAF), Space Force, and DoD are met.

Aerospace Vehicle Equipment (AVE) Products procurement targets the acquisition of reduced size, weight, and power (SWaP) space-qualified satellite cybersecurity COMSEC products. These are used in a variety of satellite applications, including LargeSat, SmallSat, CubeSat, and hosted payloads. The goal is to support the development, integration, launch, and operation of a more proliferated and resilient space architecture.

Funding will maintain the United States Space Force's (USSF) requirements for secure TT&C and mission data cryptographic products, enhancing the security posture of emerging and operational space systems.

Ground Operating Equipment (GOE) Products are also a key procurement objective, providing ground-based cryptographic equipment and algorithms necessary for secure communications with DoD satellite systems. This includes equipment for TT&C, mission data, and satellite communications (SATCOM) cybersecurity applications, which are vital for secure command and control and data transmission.

The budget increases funding to address the growing need for a resilient and proliferated ground architecture, supporting secure links between ground nodes and National Security Space System satellite platforms.

Space Modular Common Cryptography (SMCC) is another important element within this line item. The SMCC program aims to reduce development and lifecycle costs for space programs by providing a modular, upgradable, and common cryptographic solution set, fully endorsed by the National Security Agency (NSA) as the preferred approach for new National Security Space Systems. SMCC supports the future procurement of Cryptographic Modernization 2 (CM2) devices across both ground and space assets, increasing data throughput and the number of supported communication channels to meet the demands of expanding space-based communications.

The Spaceborne Equip (Comsec) program is justified by the need to protect sensitive information such as warfighter positions, mission planning, intelligence, and operational orders. Secure space communications are essential for maintaining decision superiority and preventing mission degradation due to adversarial actions. The program's funding supports rapid response to emerging threats, system resiliency, and the integration of commercial and international solutions where appropriate. By investing in advanced cryptographic products and robust sustainment, the program ensures the continued security and effectiveness of DoD space operations.
