The Department of Defense, specifically the U.S. Army Combat Capabilities Development Command (DEVCOM), is soliciting White Papers (WPs) related to the C5ISR/EW Modular Open Suite of Standards (CMOSS) under Topic FC-05, focusing on Positioning, Navigation, and Timing (PNT) Enablers and Modular Open Systems Architectures (MOSA). This initiative aims to gather information for market research and strategic planning, with the goal of integrating new capabilities into existing C5ISR systems while reducing lifecycle costs. The Army plans to award 1 to 3 contracts with a total ceiling of up to $40 million, with individual contract values ranging from $500,000 to $20 million, anticipated by June 2025. Interested parties must submit their WPs by February 15, 2025, and can contact Brian S. Townsend at brian.s.townsend6.civ@army.mil or Brian D. McGuire at brian.d.mcguire1.civ@army.mil for further information.
