The Department of Defense, through the Marine Corps Systems Command (MCSC), is conducting market research to identify industry capabilities for supporting the Marine Corps Wideband Satellite Communications – Expeditionary (MCWS-X) program. The MCSC is specifically seeking vendors who can provide system maintenance, sustainment, and the development of new terminals to enhance existing communications capabilities, as they currently rely on L3Harris for these services. The MCWS-X terminals are critical for rapid deployment and high data throughput, utilizing advanced satellite communications technology that is compatible with both legacy and future systems. Interested parties must submit their responses detailing their capabilities and proprietary information by May 7, 2025, via email to the primary contact, Victoria Downing, at victoria.downing@usmc.mil, or the secondary contact, Leigh Anne Romo, at leigh.a.romo.civ@usmc.mil.
