GCSS-MC Capability Support and Decommissioning Services

The Marine Corps Systems Command, representing the Portfolio Acquisition Executive Mission Systems, has issued a Request for Information to conduct market research aimed at identifying potential sources capable of providing services related to the capability support and decommissioning of the Global Combat Support System Marine Corps (GCSS-MC). This system is a complex Oracle-based Enterprise Resource Planning platform enhanced with custom Java and HTML forms to efficiently manage logistics, supply, and maintenance operations on a global scale, supporting over 25,000 users. The RFI specifically focuses on maintaining the current system and facilitating its decommissioning, explicitly excluding any requests for enhancements or modernization efforts. The solicitation, identified by the number M67854-26-I-4414, is a sources-sought notice with no set-aside applied, classified under NAICS code 541519. The work is overseen by the Department of Defense and is based out of the Marine Corps office in Quantico, Virginia, with performance taking place in Stafford, Virginia. Interested parties are encouraged to respond by the deadline of May 14, 2026. Primary points of contact for inquiries include Hannah Thompson and Allison Passanita. The effort seeks to ensure a smooth transition and sustained support during the phase-out of the GCSS-MC system.
