History

Origins and Establishment

The origins of the Marine Corps Systems Command (MCSC) can be traced to the Marine Corps Research, Development, and Acquisition Command (MCRDAC), which was established on November 18, 1987. This formation was mandated by the Goldwater-Nichols Department of Defense Reorganization Act of 1986, which sought to centralize acquisition functions within each military service to improve oversight, efficiency, and alignment with service-specific needs. Prior to this, Marine Corps acquisition activities were often fragmented and reliant on arrangements with other Department of Defense entities, prompting the need for a dedicated command to unify these efforts. On January 1, 1992, MCRDAC was redesignated as the (MARCORSYSCOM) through Marine Corps Order 5000, which formally authorized the new entity and outlined its responsibilities for acquisition and lifecycle management. This redesignation marked a pivotal step in evolving the command's structure to better support the full spectrum of systems development, from research to sustainment, ensuring more integrated management of Marine Corps equipment. Headquartered at , MCSC's initial focus was on consolidating previously dispersed research, development, and acquisition activities from across various Marine Corps commands into a single, unified organization. This centralization aimed to eliminate redundancies and foster a cohesive approach to equipping forces with ground weapons and systems. The early mandate emphasized enhancing procurement efficiency for ground combat systems, thereby diminishing the Marine Corps' dependence on acquisition channels from other military services and enabling more tailored, responsive support for operational needs.

Key Developments and Reorganizations

In 2017, Marine Corps Systems Command (MCSC) underwent a significant realignment to better align its acquisition efforts with the Marine Air-Ground Task Force (MAGTF) structure, reducing 32 program managers to 14, organized under four portfolios: Systems (GCES), Command Element Systems (CES), Systems (LCES), and Supporting Establishment Systems (SES). This restructuring aimed to enhance operational alignment by organizing capabilities across MAGTF elements, excluding air combat elements managed by the for Tactical Aircraft Programs, thereby streamlining support to Marine operating forces. On February 12, 2024, MCSC announced a further organizational to accelerate implementation, focusing on modernizing operations and improving efficiency in capability delivery. Key changes included consolidating tactical vehicle programs and intelligence systems under the , Land Systems (PEO LS), to foster better integration with naval acquisition processes and enhance responsiveness to evolving threats. This shift supported broader Marine Corps goals for force modernization without disrupting core portfolio functions. MCSC's 2025-2032 Strategic Plan further emphasized the integration of agile acquisition practices and data-driven decision-making to expedite the delivery of critical capabilities, such as precision fires and unmanned systems. The plan outlined standardized processes for optimizing program efficiency, including and iterative development, to align with the Marine Corps' emphasis on in contested environments. These practices have enabled MCSC to prioritize scalable solutions that support distributed operations. Notable milestones include the fielding of the (JLTV) beginning in early 2019, which replaced legacy High Mobility Multipurpose Wheeled Vehicles and enhanced ground mobility for Marine units. MCSC continues to support the 2025 Force Design Update through initiatives like the delivery of Command and Control, Communications, Computers, and Cyber Systems (CAC2S) units by the end of fiscal year 2025, providing portable command capabilities to Marine Littoral Regiments and other units.
