Communications Security (COMSEC)

The Communications Security (COMSEC) line item (LI 0125B96000) in the Army's FY 2026 budget is a critical component of the Army's information security and modernization strategy. Its overarching goal is to ensure the confidentiality, integrity, and availability of Army communications at all classification levels, including SECRET and TOP SECRET. The program supports secure battlefield operations and is essential for maintaining operational security against current and emerging cyber threats. COMSEC funding enables the procurement, fielding, and sustainment of cryptographic equipment, key management systems, and secure load devices, all of which are necessary for secure communications across tactical, strategic, and enterprise networks.

COMSEC Cryptographic Systems (CCS) is a major sub-program within this line item. CCS focuses on acquiring, upgrading, and sustaining National Security Agency (NSA)-certified products, including In-Line Network Encryptors (INE), Link family encryptors, and Secure Voice (SV) devices. These systems are designed to meet NSA's Cryptographic Modernization 2 (CM2) and High Assurance Internet Protocol Encryption (HAIPE) Binding Operational Directive requirements. CCS products are fielded at various Army echelons, from high-capacity network nodes to tactical edge users, and are priced according to network bandwidth and security needs. The program also includes recurring costs for product support, fielding, contractor management, system engineering, and training.

Army Key Management Infrastructure (AKMI) is another key sub-program. AKMI's objective is to develop, procure, and sustain systems that securely store, transport, and distribute cryptographic keys and products from the NSA Key Management Infrastructure (KMI) storefront. AKMI supports a large number of End Cryptographic Units (ECUs) and includes components such as Management Client (MGC) Nodes, Automated Communications Engineering Software (ACES), Simple Key Loader (SKL), and Next Generation Load Device - Small (NGLD-S). The program is also responsible for software convergence and integration into the Next Generation Command and Control (NGC2) architecture, increasing automation and reducing manual oversight in key distribution.

Next Generation Load Device - Medium (NGLD-M) is a new start in FY 2026. NGLD-M is designed to replace the legacy SKL, offering enhanced capabilities such as cryptographic re-programmability, Over-the-Network Keying (OTNK), and upgradability to NSA CM2 algorithms. The device supports secure issuance, filling, and management of cryptographic keys and mission planning products for ECUs. The NGLD-M program experienced a delay in FY 2025 due to NSA-driven hardware security modifications and integration cost increases, with procurement now scheduled to begin in FY 2026. The program is managed as an Acquisition Category III (ACAT III) Program of Record and involves multiple vendors.

Each sub-program within the COMSEC line item includes funding for engineering support, software maintenance, help desk operations, depot support, training, and initial spares. For NGLD-M, funding covers recurring engineering changes, user application software integration, software licenses, cybersecurity support, warranties, contractor logistics, and systems engineering. Initial spares and repair parts are procured to support fielding and sustainment, with training provided for operators and maintenance personnel. The AKMI program also includes depot support for key components, ensuring continued production and refurbishment necessary for SKL sustainment.

The justification for these investments is rooted in the need to maintain secure communications for both active and reserve components, supporting homeland defense, domestic emergency response, and military support to civil authorities. The COMSEC program aligns with statutory requirements and Army modernization priorities, particularly in addressing quantum-resistant cryptographic solutions and automation of key management processes. The procurement and sustainment of these systems are coordinated with NSA and other stakeholders to ensure compliance with evolving security directives and operational requirements.
