Global Combat Support System

The Global Combat Support System-Army (GCSS-Army) is a critical information technology program within the Department of Defense budget, aimed at providing the Army with a seamless, timely, and secure flow of logistics information. The primary objective of GCSS-Army is to enable combat forces to achieve a decisive edge by ensuring that logistical support such as supply, maintenance, ammunition, and property accountability is delivered efficiently and accurately, even in challenging operational environments. This program is a key enabler for the Army's transition to a network-centric, knowledge-based force, replacing legacy Standard Army Management Information Systems (STAMIS) with a modern, enterprise-level solution.

One of the main goals of the GCSS-Army program is to implement best business practices to streamline supply chain management, accountability, maintenance, distribution, and reporting procedures. The program supports the Army Campaign Plan's future force transition path by ensuring that logistics processes are both effective and auditable. GCSS-Army is also designed to be financially compliant, supporting the Army's enterprise strategy for financial auditability and transparency.

A significant focus of recent and current funding is the development and deployment of a Disconnected Operations Solution. This initiative addresses critical battlefield gaps where network connectivity is unavailable, such as during cyber-attacks or in remote operational areas. The disconnected architecture allows units to maintain and regenerate combat power, order and process spare parts, track battle losses, and conduct maintenance activities even when communications are disrupted. Funding is dedicated to completing the software solution for disconnected supply, ground maintenance, accountability, and the Store and Forward capability, which ensures data synchronization once connectivity is restored.

Another key component is the Continuous Enhancements effort, which uses Research, Development, Test, and Evaluation (RDT&E) funding to execute system change requests (SCRs). These enhancements are prioritized by the warfighter and are designed to improve sustainment activities, accountability, auditability, and calculations of total cost of ownership. This includes audit-related fixes, cyber updates, and the implementation of advanced Identity, Credential, and Access Management (ICAM) solutions, including privileged user access management and zero trust security principles.

The Advanced Manufacturing Data Repository (AdvM DR) is another Army priority supported under this program. The AdvM DR initiative aims to fully integrate advanced manufacturing capabilities and enable the Digital Thread within Army Enterprise Resource Planning (ERP) systems. By automating the transfer of advanced manufacturing product configuration data, this repository reduces manual efforts, ensures data accuracy, and maintains configuration control for 3D-printed and other advanced manufacturing data. Funding has been allocated to integrate the AdvM DR with the Army Futures Command's Enterprise Product Data Management system.

The GCSS-Army Enterprise Aviation initiative is also being advanced, with efforts to integrate Aircraft Notebook (ACN) data into GCSS-Army via an interface with Enterprise Aviation Middleware components. This integration supports improved aviation maintenance and logistics, contributing to overall readiness and operational effectiveness.

The GCSS-Army program's objectives are centered on modernizing Army logistics through enterprise-level solutions, enhancing operational resilience in disconnected environments, supporting audit and cybersecurity requirements, and integrating advanced manufacturing and aviation data. The program's acquisition strategy emphasizes iterative development, user-driven enhancements, and integration with broader Army digital modernization efforts.
