Global Command and Control System

The Global Command and Control System Software and Digital Technology Pilot Programs (PE 0303150K), managed by the Defense Information Systems Agency (DISA), is a critical research, development, test, and evaluation (RDT&E) initiative that underpins the Department of Defense's (DoD) ability to provide joint command and control (C2) capabilities. The primary focus of this program element is the modernization and sustainment of the Global Command and Control System-Joint (GCCS-J), which is the DoD's system of record for joint C2 and situational awareness. The program aims to deliver an integrated, near real-time operational picture to support joint, coalition, and multinational operations across air, maritime, ground, space, and cyber domains.

GCCS-J modernization is the central objective of this line item. The program's goals are to transition GCCS-J to a cloud-based, Zero Trust, and IPv6-compliant architecture, while enhancing web-based access via the SIPRNet. This modernization effort addresses evolving operational requirements, cybersecurity mandates, and the need for improved data sharing and interoperability among U.S. and coalition forces. The modernization strategy is aligned with Joint C2 (JC2) Mission operational priorities and the DoD's JC2 Reference Architecture, ensuring that the system remains responsive to the Joint Staff's annual capability requirements.

Development and strategic planning activities include decomposing existing applications into modular services, implementing agile development practices, and consolidating tools to reduce sustainment costs. The program emphasizes the use of commercial off-the-shelf (COTS) hardware and software to achieve cost efficiencies. DISA also aims to limit local deployments in favor of enterprise solutions, exposing data and scaling services to support a broader enterprise implementation. These efforts are designed to ensure that GCCS-J remains operationally effective while reducing the overall cost of ownership.

Technical transformation initiatives within the program focus on integrating a minimum viable capability of a new C2 cloud-native product line, deploying container orchestration for improved scalability and resiliency, and overhauling the legacy data model to reduce latency and simplify future upgrades. The adoption of standardized, bi-directional, CJADC2-compliant data service APIs is intended to facilitate integration with external data sources and recipients. These activities support the Combined Joint All Domain Command and Control (CJADC2) vision of seamless information sharing across all military services.

Cybersecurity and compliance are also major objectives. The program is implementing Zero Trust architecture as mandated by DoD policy, which aims to contain, impede, or stop adversaries from exploiting GCCS-J systems. The transition to an IPv6-only operational model is another compliance-driven goal, ensuring that GCCS-J remains functional as the DoD phases out IPv4 support. Ongoing cybersecurity patching, trouble ticket resolution, and the integration of spectrum information are part of the sustainment activities to maintain operational readiness and security.

Test and evaluation activities are robustly supported to ensure that all new capabilities and modernized components meet operational requirements and security standards. These include operational testing at various labs, cybersecurity assessments, and integration testing with mission partner networks. The program leverages performance-based contracting and cost-reimbursable task orders to retain flexibility and ensure that contractors meet cost, schedule, and performance objectives.
