The Department of Defense, specifically the Department of the Army's Program Executive Office Command Control, Communications: Tactical (PEO C3T), is seeking recommendations for hardware and software architecture related to Cross Domain Solutions (CDS). The objective is to enhance interoperability between security domains, enabling the timely exchange of critical information such as Situational Awareness, Command and Control, and Intelligence data among U.S. forces and mission partners. This initiative is vital for maintaining information dominance and operational effectiveness in military operations. Interested vendors must submit their responses electronically by noon (12 PM) EST on November 1, 2024, and can direct inquiries to Virginia Pippen at virginia.a.pippen.civ@army.mil or Cynthia Grove at cynthia.a.grove.ctr@army.mil.
