Global Combat Support System

Abstract

GCSS-Army gives combat forces a decisive edge by providing soldiers a seamless flow of timely, accurate, accessible, and secure logistics information to get combat power at the right place, at the right time. The GCSS-Army program is an information and communications technology investment that provides key enabling support to the transformation of the Army into a network-centric, knowledge-based future force. The GCSS-Army approved Capability Development Document (CDD) and Capability Production Document (CPD) require an enterprise approach to replace current logistics and maintenance Standard Army Management Information Systems (STAMIS) to include supply, maintenance, ammunition, aviation, and property book. GCSS-Army implements best business practices to streamline supply, accountability, maintenance, distribution, and reporting procedures in support of the future force transition path of The Army Campaign Plan. GCSS-Army must take critical steps towards integration and implementation of the next generation of Enterprise Business Systems capabilities. This effort will address the obsolescence of existing SAP Enterprise Resource Planning (ERP) logistics and financial management platforms. GCSS-Army's modernization work sets the conditions for development of a converged, post-modern Defense Business System that streamlines and integrates the Army's core business functions. GCSS-Army must identify redundant processes as candidates for business process re-engineering. Funding will support the 1) market research of Industry best practices, 2) Initiation of an Army Enterprise Development Environment to enable prototyping which reduces risk by aiding the requirements development. This environment includes: Cloud-hosted infrastructure, applications, and programs and tools, 3) government Program Management and Systems Engineering and Technical Assistance (SETA) contractors needed to plan for and manage the initiation of the post-modern system implementation effort. The funds in the GCSS-Army Research Development Test & Evaluation (RDT&E) line are for building the software solution for disconnected supply, ground maintenance and accountability, and Store and Forward Capability. Enterprise Resource Plan (ERP) modernization supported EBS-C in FY 2023 before full transition of efforts to EBS-C in FY 2024. GCSS-Army Project EK2 (Aviation logistics) completed in FY 2023. The Aviation sustainment effort has been rolled into the GCSS-Army Capability Support using mostly OMA. In FY 2024 after transition to capability support, RDT&E funding for Continuous Enhancements will be used to execute system change requests (SCRs) to enhance sustainment activities, accountability, auditability, and calculations of total cost of ownership. Implementation of SCRs enhance capability support and effectiveness by synchronizing system data and utilizing enterprise interface tools to eliminate input errors. FY 2025 Base dollars in the amount of $2.566 million will continue to support GCSS-Army Audit related fixes and Cyber updates. Other planned FY 2025 enhancements include: G-Invoicing, Enhancement Pack 8, and follow-on Identity, Credential, and Access Management (ICAM) to include privilege user access management and zero trust. The FY 2025 RDT&E funds will also be used to complete the software solution for disconnected supply, ground maintenance and accountability, and Store and Forward Capability. GCSS-Army Enterprise Aviation is integrating the Aircraft Notebook (ACN) data into GCSS-Army via an interface with the Enterprise Aviation Middleware components. Advanced Manufacturing (AdvM) Data Repository (DR) is an Army priority. AdvM DR will fully integrate AdvM capabilities and enable Digital Thread (DT) within the Army ERPs. It will integrate the AdvM DR with the Army Futures Command (AFC) Enterprise Product Management (ePDM) system providing a fully automated capability for the transfer of the AdvM product configuration data to the AdvM DR. Capability will reduce manual efforts to transfer configuration data to the AdvM DR ensuring accuracy and maintaining configuration of AdvM print data.
