MARINE CORPS SYSTEMS COMMAND (MARCORSYSCOM)

Marine Corps Systems Command (MARCORSYSCOM) is the acquisition command of the Marine Corps, serving as head of contracting authority, exercising technical authority for all Marine Corps ground weapon and information technology programs. Our mission is to equip and sustain Marine forces with the most capable and cost-effective systems for current and future expeditionary and crisis-response operations. This mission focus informs the command’s two primary lines of effort: program execution and program executive office support.

MARCORSYSCOM is both a Naval Systems Command and a Headquarters Marine Corps organization. The Commander reports to CMC for operating forces support and logistics sustainment responsibilities and as the Marine Corps “Proponent” for acquisition. As a Naval SYSCOM commander, COMMARCORSYSCOM has oversight responsibility and authority for core acquisition processes, including cost estimating: technology development and technical readiness assessment; systems engineering; test and evaluation; maintenance and modernization planning; configuration management; comptroller and legal support. Responsibilities also include incorporating advanced technology and lessons learned into the design, maintenance, modernization, and acquisition specifications that apply to weapons and IT systems; in-service support; providing support services to PEOs; executing safety programs in accordance with the Marine Corps Safety Program; and serving as the operational safety and assurance certification authority for the ground weapon and IT system program portfolio.

We execute over 450 acquisition programs aligned as weapon and/or IT system portfolios to the corresponding Marine Air-Ground Task Force element, including Command Element Systems, Ground Combat Element Systems, Logistics Combat Element Systems, and Supporting Establishment Systems (corresponding to the MAGTF’s “fifth element,” the entire Supporting Establishment of the Marine Corps). Individual programs within these MAGTF portfolios comprise the development and production of systems for command, control, communications and intelligence; infantry equipment and weapons, tanks and fire support, and infantry squad integration; supply, maintenance, ammunition, engineering, and medical; information technology; the light armored vehicle; and training systems.
